This video is an excellent example of just what an informative, no-nonsense presentation looks like. All of the information a person would want to know on the subject without anything else getting in the way of its efficiency. Outstanding work, my friend.
This was one of the better reviews i have seen. I do appreciate how you showed the temperature of the batteries as they charge. Thank you for this video!
Great video. I've had the 40v 19 inch mower, string trimmer, hedge trimmer, and blower/vacuum, for the past 4 years. I have nothing but good things to say about it. I will admit that the 80v is tempting. The tools appear to be a sturdier quality and build.
Clay McDonald I also have the 40v 19” mower, I bought it in June 2016 and it does a good job as long as I don’t skip a week mowing my lawn (if I’m bagging it). Haven’t had any problems yet using it once or twice a week during rain seasons. I’m getting tempted to buy the 80v lawn mower as well but I already invested in an extra 40v spare battery ($90 on amazon) besides the ones that came with the mower. Patience my friend!!!
Good review. I don't know much about electrical, but my primary question is whether the 80V mower with the 4AH battery will "power through" my tall thick grass any better than the 40V mower with the 4AH battery. I'm in the market to buy a new cordless battery-powered mower and this is really my biggest need. Thanks!
I bought the 40 V 2Ah version with 2 batteries supplied as the 80V lawner seemed too heavy to move around trees in out of the garage, etc. The 40V has lots more power than previous 10 year old Bosch 36V Rotak. Went through my 'meadow' style lawn with lots of clover with ease. So I'm happy, the 40 volt more than meets my needs in terms of power. I also prefer that size in case I buy the hedge cutter and lawn trimmer with the 40 v. Those tools with the 80V wer very big and looked like tools for the strongest man competition. But I've only got about 400 square meters so much smaller than backyards I see in the US videos here. Having said that the 80V charging system with ventilator seems higher quality that should mean longer battery life.
Good video but it doesn't really address any performance advantages/disadvantages of 80v over 40v, if there are? In the spreadsheet it looks like the 2ah/80 is comparable to the 4ah/40, at approx 145 watt hours, with the 80v being heavier and more expensive. Also cells get smaller as voltage goes up. So what's the advantage of higher voltage? What are you getting? With power tools it always seems like the 12 to 18v jump is better.
I like your reviews. Thank you. I just ordered from Amazon an 18 inch 80 volt saw. I have a plug in electric saw and I really like how I can relax and think about my next cut in a quiet non hurried environment.
4:40 This is so much more useful than amp hours, but manufacturers insist on advertising the latter only, which is actually a big disadvantage for higher voltage systems.
@@tominomaza actual capacity is amp hours * voltage. lets say you have two batteries that are the exact same capacity. but if you only advertise in amp hours, then the battery with 1/4th the voltage will have 4x greater amp hours listed. This makes high voltage systems seem like they have a smaller battery because its less amp hours, when in reality its the same. A 2AH battery for a 80V system is the same size as a 8AH battery for a 20V system. Both batteries have the same capacity of 160 watt hours of work its able to do.
@@BoopSnoot Ok, I did not know they not advertise Wh before. So 40V 6Ah should be the same run time as 60V 6Ah but more powerful when mowing high grass, right? I can not make decision. Here is only 40V and 60V both available with 2, 4 and 6Ah batteries. I am still very skeptical about battery life in self-prop mouwer as (greenworkstools.eu/cz/en/products/lawn-mowers-gd60lm46hp ) They claim about 80minuts with 4Ah, but there are videos when it run with 5Ah up 20minutes not even high grass.. I have about 1500m2 its like 1/3 acre.. 50% is steepe. I count on to buy at least 3 x 40V 6ah (in total 648wh) or 2 x 60V 6ah what is the same 648wh in total. And now the price for the wh is almost the same here. I guess I do more squer feet with 60V
@@tominomaza Greenworks is a reputable brand, and brushless are more energy efficient than brushed motors. That is also a variable speed mower, which means it doesn't always run at 60V, and will down the voltage depending on the grass height and grass type, and you'll be able to hear when it goes into "high power" mode for tough spots. 40V is not powerful enough IMO, and 60V would be the way to go, but personally I went with the 21" 80V version. The batteries are rapid charge, so you don't need as many as you think. If you mow the front with a small battery for example, you can take a 15 min break to get some water, and by the time you're done the battery will probably be topped off in the rapid charger anyway. Its not like the old lead-acid mowers where they trickle charge. I also save money by using the same 2AH 80V battery in all my devices (trimmer, blower, hedger), as the battery is far more expensive than the tools usually.
The quality between 40V and 80V Greenworks tools is like night and day and has nothing to do with the batteries. 80V tools is more toward commercial duty whereas 40V more occasional homeowner duty. That is just Greenworks, there could engineered the other way around. Just look at the Milwaukee 10" miter saw, crazy power on an 18V battery.
Yeah, I'd imagine while volts and amps play big roles, a bigger difference could easily be made with a superior electric motor assembly with say, a larger/more powerful neodymium magnet for extra efficiency.
Actually the measured max voltage (at least for the Greeenworks 4AH "PRO") is 82vdc. I believe the Commercial GreenWorks 82V batteries are actually exactly the same.
The 40 volt batteries being a slide system will be more future proof though, cause you can leave room for bigger batteries in the tool itself. The 80 volt batteries would have to get taller for higher capacity batteries. Which doesn’t leave much room
The buttons and lights on the newer 40 volt batteries are like the 80 volt now. I have both the old and new 40 volt, and they perform the same, but the new 40 volt has no air channels, so it still gets hot when charging.
I have a Kobalt 40V mower and I have a Greenworks 80V mower I would say that the 80V is much stronger and lasts a bit longer, However, the Kobalt 40V is the best looking grass I've seen!!
In mid 2023, Greenworks introduced a 40-volt rapid charger that charges at 5 amps. They probably did that to conveniently charge their 8-amp-hour 40V battery, which they introduced at the same time.
I have the Kobalt system, batteries are the same as Greenworks with a slight form factor but you could make it interchangeable. Kobalt 40V and 80V garden tools are made by Greenworks based in Canada. It's not just about the batteries, 40V tools are toys where 80V are commercial duty. Difference like day and night. 40V maybe OK if your demand is not heavy.
Hello Jesse. Say, I have multiple Kobalt 80v tools which are actually made by Greenworks, one of which came with a silent charger, no cooling fan. Battery gets really warm while charging. This is odd to me. All of my other chargers came with cooling fans and charge with 4 amps. The silent no fan one says 2amps on the bottom label. Which charger will preserve the longevity of the battery packs better? 2 amps and no fan? Or 4 amps with active cooling? Thank you. David
I have two 40 volt batteries, one i just purchased a day or so ago from Amazon, the original battery shows only two green lights , and will not fully charge, can the older battery be recycled or repaired
The thermal charger pics made me decide against any 40v Greenworks, and I wonder about 40v/36v licensees. (For now I expect the 60v chargers would be okay.)
Nice to run into this review. I would like to know more on your experience whacking weeds with 40v and 80v trimmers. In replying to J. Wagoner you said "power and efficiency". Efficiency, certainly. I well understand the efficiency of higher voltage (less heat, smaller wires). But in actual use can you further characterize the difference in whacking thick weeds using a 40v vs an 80v trimmer. Let me add that I just decided to buy a cordless trimmer, but wanted to see if the battery units were "ready for prime time" compared to gas powered units. I went out and bought 5 different brand/models of cordless trimmers to compare. I found that for the weeds I need to trim (coastal scrub in California, which are a bit on the gnarly side) the 40V Greenworks unit a bought did a great job, and the 80V Kobalt unit I bought also did a great job. But in using the two for 10-15 minutes I didn't notice that the 80v unit was all that much more powerful. In other words, I didn't run into any weeds that the 40V could not whack that the 80v could. That's why I'd like to hear your thoughts. :> Finally, for reasons other than pure whacking power, I fell in love with the 80v Kobalt trimmer. It just was the all round best of the five. As best as I can tell the 80v Kobalt unit is nearly identical to the 80v Greenworks unit, and in fact it is claimed that the Kobalt is just a re-branded Greenworks made for specifically for Lowes. If true, the biggest difference between the two right now may be PRICE. The latest model 80v Greenworks trimmer -attachment capable- on Amazon is a whopping $348 with 2AH battery (www.amazon.com/dp/B00YBFXCMI?ref=emc_p_m_9_b). The 80v Kobalt trimmer at Lowes with the same battery is only $199 (www.lowes.com/pd/Kobalt-80-volt-16-in-Straight-Brushless-Attachment-Compatible-Cordless-String-Trimmer-Battery-Included/50394980.) WOW!!!
I’ve got a review of the 80v trimmer vs a Stihl gas trimmer here: Greenworks 16-Inch PRO 80V String Trimmer Review and Comparison ua-cam.com/video/B7BZRWSc1qY/v-deo.html
I feel pretty silly but we have the 80v and I can’t see an easy way to eject the battery after charging. We end up tapping it on its end with our hands - trying to encourage it out of the charger. Our hands get sore with this method. Am I missing a release mechanism of some kind? I can’t see an easier way!
Excellent review! Thanks for putting the thought and effort into this. The extra detail you added from your personal use was truly helpful, as was the cooling mechanisms.
I bought the Greenworks 80v snowblower in the hope that I could expand to other devices with 80v batteries. However, I don't see any other devices that use 80v batts from Greenworks.
Great video, much appreciated. Thanks. It's probably been said and I've missed it, but is there an actual power difference between the 40v and 80v systems? My guess would be that if there is it's related to the tool itself, not the battery. We use a couple different Makita 18v impact drivers at work and one model definitely has more power than the other, both using the same battery. I'm leaning toward the 80v simply because I'm guessing it's a little better tool (battery notwithstanding).
the difference in the battery life between those drills is probably that one is a brushless DC motor vs one that is an older style brushed DC motor. The brushless motors are significantly more efficient and will give you more run time and/or more torque from the drill to get the job done.
The 80 volt is a more powerful tool. Have a 40 volt edger. The battery was mia. Bought a CRZ 428 mower. Replaced the 40 volt edger with a 82 volt edger. The 82 volt is a beast. Homeowner not a commercial lawn care user. Like buying from a dealer.
Love the Videos you did on the 80V. You give alot off info that the MFG doesn't. Also, I believe the high amp 80V it taller. I put on some 60V videos and the 60V and 80V are amazingly similar. I'd love to see how quick you can get through a 15in pine with the 80V, I got through in 33sec with a standard chain. It would be a much better estimate of power between the 2 saws.
Can you interchange the batteries on all products? I'm considering the hedge trimmer but noticed the 2 amp battery that is unlike the other Greenworks 4 amp tools I own. Thanks for the video.
Theoretically you can use all the 40v batteries in the 40v tools and all the 80v batteries in the 80v tools, but practically sometimes the 2ah batteries don’t last long enough (80v mower) and sometimes the 4ah batteries are too heavy (80v chainsaw and trimmer).
Ok, so what I don't understand about the difference between a 40v and 80v setup is does the 80v deliver more power or capacity or both? Debating (with myself) on buying the Greenworks snowblower. Do the 40v and 80v models have the same size motors? Will the 80v just run longer or is it also turning the motor at a higher rpm rate? What's the deal? Thanks.
It’s hard to explain. Higher voltage means greater efficiency with thinner wiring usually. So yes, usually that will translate into more power, greater run times, etc, but a lot of that comes down to the engineering in the rest of the system. If a 40v system and an 80v system perform the same, usually the 40v system will be heavier. Hope that helps.
@@createthisdotcom Som how does that help me decide? Looks like the 80v package doesn't give me much more for the money (assuming they perform the same which I actually have no idea about) other than less weight or am I missing something?
No. For the same power, the higher the voltage, the lower the current; and the lower the current, the lower the overall losses and the better the whole system efficiency. So, increase the voltage is always a better option. @creathis : Talking about efficiency, and without any polemics, it seems quite silly to start from gasoline, pass through a generator, converting to a sinusoidal voltage to supply the AC to DC converter (its own charger) to eventually charging the battery. It would be justified only in case of emergency, I mean, if there would be no available utility plug.....
I'd stay away from GreenWorks tool altogether...unless you want all your batteries to die less than a year. I have over 8 of them...ALL DEAD!!! waste of $$$ 80v, 40v, & 24v.
@@svldvc i have 7 tools, and most the batteries are fine. 1 of the 4 batteries i have is starting to show it's age, but that's 4 years old. Not expecting 20 years for a battery. I smell a extreme exaggeration when it comes to battery life. Since Greenworks has a 3 year warranty including the battery. may i have them so i can return all 8 for a replacement?
I just got a GreenWorks self-propel mower I think 21in I have 1 40volt gmax 4amp lithium ion batter I’m only getting 30mins roughly of mowing time my yard is lot bigger and need 1.25 more charges to finish would it be worth getting the 5amp for my secondary battery so I can get done hopefully all at once or is it not run much longer then the 4amp and save lil money n just get another 4amp I think price now is around 120 bucks where the 5amp is 180 any advise be helpful
Sorry, I’m not sure. I don’t have the 5 amp hour. I know there was a huge run time boost from the 2 amp hour to the 4 amp hour. I wouldn’t expect the 5 to be that dramatic of a difference compared to a 4 amp hour though.
So my 4 times using my 21in deck self propelled mower 40volt with a 40volt 4apm battery got 30mins first time use 2 time 25 3rd time 16 mins and this last time around only 6mins all on full charge and when I push the light on the battery see what’s left nothing so it’s drained wouldn’t recommend the 40volt mowers from GreenWorks battery is just not cutting it taking me ages to mow my yard with having to always recharge and getting shorter run times each time
I have the 80 V battery two... for my lawn mower... the left battery works however, the right battery will not.. states that it is charged , when I put it in the Charger nothing activated to show charge or complete. When I mow the left battery is fine, when exhausted it should switch to the right battery but NO.... and the Customer Service is horrible.... I will need to return to Costco due to battery issue?
I have several Greenworks 40v tools. Was looking for an extra 4 amphr battery and was confused that the prices on eBay were all over the place with many model numbers referenced. Prices went from $48 to $180. what’s that about?
Would you happen to know what the run time would be on the 80 V 5 amp hour battery when it is used in a Greenworks Pro 21 in. 80V 3 in 1 Self-propelled Mower
What are good examples of why you would prefer the 80 volt over the 40 volt ( as far as the tool goes) ? I mean why would anyone want an 80 volt weed trimmer?
Depends on what you use it for, how you store it, how often you cycle it, etc. If you run the smaller 80v batteries in a high draw application like the mower I have, they will heat up more and probably won’t last as long. However, if you size them properly to the application and store them above freezing you should get good life out of them. Cycle life for lithium ion is a curve and the battery typically is considered to need replacement once the battery is delivering 80% of it’s rated capacity. They typically do that after 300 to 500 cycles. So let’s say you mow your lawn once a week. There are 52 weeks in a year, but let’s say you mow only half of those because winter. So 26 mowings per year, 26 cycles. 300 cycles divided by 26 is 11.5 years! Will they actually last that long? I have no idea. I really wouldn’t bet on it. But they might. That’s what the math says. Mine are all still going strong since I made this video. I see no reduction in capacity. HTH.
i was thinking of buying a 80v GW snow blower but not have to rid myself of the 40v line. I wonder how plausible it would be to combine 2 40v batteries in series and use it on the 80v blower? All I would need is a empty 80V casing and some 12G wire.
Very Good and Detailed Comparison and Review!! I'm gonna be putting the 40v battery to the test this Winter 🥶 since I just bought the Green works 40v Cordless Snowblower lol
Excuse me if this is a silly question but the higher voltage systems 80v vs 60v vs 40v vs 25v - just means that the batteries charge quicker? Are the actual run times longer or is it more about having extra power and quicker charge time?
+Jack Sassenfeld it's not a silly question. Higher voltage means the wires can be thinner while delivering more power. Basically, lighter and more efficient, but possibly more dangerous too.
Jack, the battery energy capacity actually should be measured in Watt hours. Higher voltage (with the same power) is better for higher efficiency and less heat while working/charging. It also should be noted that in US most sompanies use "mmarketing voltage" while in EU it is nominal numbers that are just multiplied nominal cell voltage (3,6V). So the real world lithium batteries are mostly 18/36/72V.
Frank W it's a yes and no at the same time. Lower voltage/higher Ah battery will need higher peak and avg. current to charge, causing higher heat emission from (basically) the same cells. This will lead to shorter cell life.
Incredibly helpful information! Very detailed for sure. Thank you for making this video! Do you own a landscape company? Is that what you use the greenwork line of tools for? Thanks, Riley
No, I’m not a professional landscaper. I just found myself in a situation where I had a bunch of batteries and had used them and thought other people might find it useful to hear my thoughts.
@@createthisdotcom Well thank you for thinking of others and making this video. I just bought a greenworks 80v hedge trimmer kit that came with charger and battery. Bought a backup 4ahr battery as well to go with it. Looking forward to building a tool set that is mainly electric and looks like a greenworks chainsaw might be the next add on ☺️
Yes, the 80v chainsaw is excellent, especially with a replacement Oregon chain and bar. I can’t recommend it enough. Just used it yesterday to trim my Christmas tree. Happy holidays!
Good video but can you dumb down the charge/electricity cost for me? Will I notice a big bump on our power bill with weekly weed trimming with an 80V? And how is that comparable to gas (trying to ignore our current high prices)?
You would have to have either very high electric rates or many of these batteries in constant rotation to even notice a change in your electric bill at all. Electric is almost always cheaper than gas when it comes to tools and vehicles (not so much heat, but that’s a different kind of gas).
Hey Excellent comparison. People need to know what volts and amp hours. Larger volt systems indicates a heavier duty motor., Greenworks Commercial 82 volt systems. Yet another.
Thank you. Is there a difference is power between the 40 and 80? I'm asking particularly because I'm trying to decide between the 40v and 80v leaf blower, i.e. would an 80v powered blower be more powerful or not?
Nice technical video, well explained. As I cannot get information anywhere else I thought I would ask, is there a torque difference in mowers when you use a 80v vs the 40V, Which one has the more power to tough it through thick grass, and also chop up leaves, vacuum leaves?
My 40v mower uses two small blades. My 80v mower uses one large blade. So yeah, there’s obviously a torque differences in the motors, but they’ve designed the lower torque system to do roughly the same work. The 80v is always going to be stronger though. For me it’s more about runtime and cut quality. The 80v mower with the 4ah battery goes a lot longer between battery swaps. And the 40v mower tended to leave a run of uncut grass between the two blades so you had to go over everything twice. I strongly recommend the 80v mower.
@@createthisdotcom I have the newest 40V Kobalt mower (manual push) and it has one blade. Been impressed so far. I think it is relabeled by Greenworks for Kobalt. Super solid deck, wheels, etc. Not so plastic like the Ryobi or earlier versions of the 40V Kobalts.
It is technically possible to build such a tool. They’re called buck converters. However, I don’t think greenworks makes one for their own battery systems.
the 40v 2AH battery and 80v 2AH battery both take an hour to charge.. those charge faster than the 40v 4AH battery because they are only half the capacity.. nothing to do with volts
Actual usage life is not mentioned…. The 80 watt betteries last 15-20 minutes in a lawn mower . Takes 2 batteries to cut a very small lawn. Any way to lengthen the actual cutting life of these? A battery hack?
Could someone please explain the relationship of the volts in the battery to the engine- I would assume that the running time of the 80 volt would be greater than the 40 volt- does the voltage co-ordinate with the engine in any way? for example, doe it increase the rpm's, or the torque, or the performance of the engine in any way? Thanks
Higher voltage just means the wiring can be thinner to deliver the same amount of power. Practically speaking, I think you’ll find that higher voltage products tend to be more powerful because of this, but from a strict engineering perspective that doesn’t have to be the case. It’s just that commercial products tend to be made as cheaply as possible and yet still get the job done. So higher voltage tends to be more powerful.
Additional advantage to higher voltage: higher voltage electric motors are more efficient. Also, for the same work load (Watts), the battery contacts current on the higher voltage packs is less than the lower voltage packs.... Watts = Volts x Amps. This means the battery and tool contacts will last longer... experience speaking :-) Running a gas generator to charge an electric mower...? seems to defeat one of the big purposes of having battery powered mowers... but that's my opinion.
Please advice! I can not make decision. Here is only 40V and 60V available. I am still very skeptical about battery life in self-prop mouwer as (greenworkstools.eu/cz/en/products/lawn-mowers-gd60lm46hp ) They claim about 80minuts with 4Ah, but there are videos when it run with 5Ah up 20minutes not even high grass.. I have about 1500m2 its like 1/3 acre.. 50% is steepe. I guess a gas mower only my chance.
Great video. I’m looking at a two Greenworks snow throwers. One is a 40V 4AH system smaller unit and can be stored away nicely and not take up room. The other is a 80V 4AH system. A much bigger machine and will take up more room for storage. Of course the prices don’t compare to each other. Reading specs on the units they both seem to have the same estimated run time of 45 min under load. Out of the 2 machines I’m more interested in the actual power performance and how long the machine would operate for? As well as which machine could work through heavier snow. What you think?
Green works has a big issue with having 40v, 60v, and 80v systems. There is no universal charger.once you choose one, You are stuck. At least with other brands. They keep everything the same for the most part. If they want you to go from 20v to 80v. It is really about just adding more batteries to the machine.
The Ah rating is the best measure of battery capacity, not the voltage. An 80v 2.5Ah battery, in theory, isnt going to cut it any better than a 40v 4Ah battery, it's perhaps just a tiny bit more powerful and not that you'd notice in the real world. The 4ah will run hotter as it's a smaller more energy dense battery trying to produce similar power to the 2.5ah (80v). You cant use voltage as an indicator of power, it doesnt work that way. As a rule of thumb I've seen that a 4ah battery is the absolute minimum, regardless of voltage, but 5ah upwards is MUCH better. A larger voltage battery will run cooler than a 40V, but you'll still want 4 or 5ah as minimum even with higher voltage.
Very thorough and informative video - thank you. Your temperature while charging pics caught my attention, as I just finished reading a review on Amazon from a guy who's workshop caught on fire when he left his Greenworks battery charging overnight. I think I'm going to try and rig a cooling fan to the charger. Have you looked into this?
That’s because how long they last entirely depends on the tool you are using and the load on the tool. A mower in high grass will kill a battery faster than a mower in low grass, for example.
@@whyno713 yes, watt hours is a good indication of how long a battery lasts. It's not the only indicator, because sometimes a given battery may handle higher amp loads better than another battery of the same watt hour capacity, but watt hours is probably the best metric we have to compare two battery run times given the same tool.
I really enjoyed your video. I purchased the leaf blower Green works pro and it came with a 60 volt lithium Max battery and then it says 2.5 which of course I don't believe either one of those or this one was not disgusting your video my question is do I want to leave the battery on the charger I do almost as storage and it's always plugged in I was just using it outside and of course I was using high power which I know lessons the amount that I have and then I just started wondering if leaving the battery charger on the charger after it's charged is okay or not okay and I didn't know if the 60 volt batteries charger has a fan in it like you were saying the larger of the two dead that you were explaining about the 80 so I don't know I was thinking about just getting another battery and so I'd have to charge so when I was out there for that 20 minutes and I have maybe 15 more minutes to go I could just switch to a battery that's already charged but they're not cheap yeah actually want the prices I saw I'm almost better off going and getting another one with a leaf blower I mean I want to say that battery was like what 160 and you can get the whole shebang for 199 I know I got a good deal on it that Lowe's but yeah I don't know and I don't know what terms of UA-cam I just agreed to by sending you this message hopefully that's nothing important yeah I just any anything more that you can tell me about the 60 I would appreciate it I do wish they made a battery that could last longer and I don't even know if Green works is made in the USA or somewhere else I honestly I should pay attention more but I didn'tthank you very much I don't know how I'll know that you answered me but I guess maybe try to check back here? I'm the technically challenged one.yeah I just I don't know I didn't want I thought maybe it's damaging the battery by leaving it on the charger I'm hoping that because I've been doing it for about a year just crossed my mind today and I don't know if it's worth trying to get another battery just get a whole another one have a extra leaf blower on me? I will tell you I live in an apartment on the second floor we have outside steps that are always well right now full of leaves and stuff and I used to sweep them and I'm disabled I'm young but I'm disabled and standing for so long isn't as easy as it used to be and I absolutely love the before I mean it really I can hit blow cobwebs or whatever is going on up above me or around the door or it's just a quick easy way and who doesn't love a toy I might be 58 years old but men still like we still like our toys and I knew I wasn't going to want to do a plug-in that would have been a nightmare and this way I can recharge sometimes and go around and hit the neighbors entryways and maybe their patios help clean the blow the leaves out for them. Cordless was definitely the way to go just wish the batteries could be made to last longer wishful thinking I did like the idea of the 80 charging faster I believe yes I got to watch your video again but because yeah let me know on the battery if it's okay to leave it on there if once it's charged I should undo it should I just unplug it from the wall obviously too then hopefully someday I'll have a garage again I hate living in an apartment especially on the second floor but I guess I need some extra size thank you again for your time to my question
For the mower, yeah, it’s pretty good. Too heavy for the trimmer or chainsaw though. I hesitate to say it’s the best as I think there is a 5.0ah battery too and I haven’t tried it.
You will have the same performance. It's wierd how all this power tools rate the voltage. These are lithium ion batteries and they use 20 batteries in series with a nominal power of 72v and a maximum power of 82v. I'm not sure why they don't use the nominal power instead. these batteries have the same characteristics of a 72v rated ebike battery

This video is an excellent example of just what an informative, no-nonsense presentation looks like. All of the information a person would want to know on the subject without anything else getting in the way of its efficiency. Outstanding work, my friend.
This was one of the better reviews i have seen. I do appreciate how you showed the temperature of the batteries as they charge. Thank you for this video!
If I'm not mistaken the 40 volt system uses passive convection cooling the 80 volt an air driven fan. At least that's what it sounded like.
Great video. I've had the 40v 19 inch mower, string trimmer, hedge trimmer, and blower/vacuum, for the past 4 years. I have nothing but good things to say about it. I will admit that the 80v is tempting. The tools appear to be a sturdier quality and build.
Clay McDonald I also have the 40v 19” mower, I bought it in June 2016 and it does a good job as long as I don’t skip a week mowing my lawn (if I’m bagging it). Haven’t had any problems yet using it once or twice a week during rain seasons. I’m getting tempted to buy the 80v lawn mower as well but I already invested in an extra 40v spare battery ($90 on amazon) besides the ones that came with the mower. Patience my friend!!!
Good review. I don't know much about electrical, but my primary question is whether the 80V mower with the 4AH battery will "power through" my tall thick grass any better than the 40V mower with the 4AH battery. I'm in the market to buy a new cordless battery-powered mower and this is really my biggest need. Thanks!
Way more power with 80v. 4ah = duration battery lasts. 80v = power and efficiency.
createthis Thanks man, I appreciate it.
I bought the 40 V 2Ah version with 2 batteries supplied as the 80V lawner seemed too heavy to move around trees in out of the garage, etc. The 40V has lots more power than previous 10 year old Bosch 36V Rotak. Went through my 'meadow' style lawn with lots of clover with ease. So I'm happy, the 40 volt more than meets my needs in terms of power.
I also prefer that size in case I buy the hedge cutter and lawn trimmer with the 40 v. Those tools with the 80V wer very big and looked like tools for the strongest man competition. But I've only got about 400 square meters so much smaller than backyards I see in the US videos here.
Having said that the 80V charging system with ventilator seems higher quality that should mean longer battery life.
Good video but it doesn't really address any performance advantages/disadvantages of 80v over 40v, if there are? In the spreadsheet it looks like the 2ah/80 is comparable to the 4ah/40, at approx 145 watt hours, with the 80v being heavier and more expensive. Also cells get smaller as voltage goes up. So what's the advantage of higher voltage? What are you getting? With power tools it always seems like the 12 to 18v jump is better.
I am curious about that as well. 14 inch 40 v chain saw 2.5 or 80 volt 16.
Generally speaking - used for more power hungry tools/vehicles, more power output, faster charging speeds
I like your reviews. Thank you. I just ordered from Amazon an 18 inch 80 volt saw. I have a plug in electric saw and I really like how I can relax and think about my next cut in a quiet non hurried environment.
4:40 This is so much more useful than amp hours, but manufacturers insist on advertising the latter only, which is actually a big disadvantage for higher voltage systems.
Why it is disadvantage for higher voltage systems.?
@@tominomaza actual capacity is amp hours * voltage. lets say you have two batteries that are the exact same capacity. but if you only advertise in amp hours, then the battery with 1/4th the voltage will have 4x greater amp hours listed. This makes high voltage systems seem like they have a smaller battery because its less amp hours, when in reality its the same. A 2AH battery for a 80V system is the same size as a 8AH battery for a 20V system. Both batteries have the same capacity of 160 watt hours of work its able to do.
@@BoopSnoot Ok, I did not know they not advertise Wh before. So 40V 6Ah should be the same run time as 60V 6Ah but more powerful when mowing high grass, right? I can not make decision. Here is only 40V and 60V both available with 2, 4 and 6Ah batteries. I am still very skeptical about battery life in self-prop mouwer as (greenworkstools.eu/cz/en/products/lawn-mowers-gd60lm46hp ) They claim about 80minuts with 4Ah, but there are videos when it run with 5Ah up 20minutes not even high grass.. I have about 1500m2 its like 1/3 acre.. 50% is steepe. I count on to buy at least 3 x 40V 6ah (in total 648wh) or 2 x 60V 6ah what is the same 648wh in total. And now the price for the wh is almost the same here. I guess I do more squer feet with 60V
@@tominomaza Greenworks is a reputable brand, and brushless are more energy efficient than brushed motors. That is also a variable speed mower, which means it doesn't always run at 60V, and will down the voltage depending on the grass height and grass type, and you'll be able to hear when it goes into "high power" mode for tough spots. 40V is not powerful enough IMO, and 60V would be the way to go, but personally I went with the 21" 80V version. The batteries are rapid charge, so you don't need as many as you think. If you mow the front with a small battery for example, you can take a 15 min break to get some water, and by the time you're done the battery will probably be topped off in the rapid charger anyway. Its not like the old lead-acid mowers where they trickle charge. I also save money by using the same 2AH 80V battery in all my devices (trimmer, blower, hedger), as the battery is far more expensive than the tools usually.
Great review - Thanks ! Have you ever compared the 80V GW to the 60V GW ?
Hello.
Have you solved your question?
Did you manage to find a comparison?
I'm looking for a little different.
It is necessary to compare 60 and 82V.
The quality between 40V and 80V Greenworks tools is like night and day and has nothing to do with the batteries. 80V tools is more toward commercial duty whereas 40V more occasional homeowner duty. That is just Greenworks, there could engineered the other way around. Just look at the Milwaukee 10" miter saw, crazy power on an 18V battery.
Yeah, I'd imagine while volts and amps play big roles, a bigger difference could easily be made with a superior electric motor assembly with say, a larger/more powerful neodymium magnet for extra efficiency.
Actually the measured max voltage (at least for the Greeenworks 4AH "PRO") is 82vdc. I believe the Commercial GreenWorks 82V batteries are actually exactly the same.
The 40 volt batteries being a slide system will be more future proof though, cause you can leave room for bigger batteries in the tool itself. The 80 volt batteries would have to get taller for higher capacity batteries. Which doesn’t leave much room
The buttons and lights on the newer 40 volt batteries are like the 80 volt now. I have both the old and new 40 volt, and they perform the same, but the new 40 volt has no air channels, so it still gets hot when charging.
To use the 40v battery outside the tool, it needs to enabled. Do you know how this is done (C & Ω terminals)?
I have a Kobalt 40V mower and I have a Greenworks 80V mower I would say that the 80V is much stronger and lasts a bit longer, However, the Kobalt 40V is the best looking grass I've seen!!
In mid 2023, Greenworks introduced a 40-volt rapid charger that charges at 5 amps. They probably did that to conveniently charge their 8-amp-hour 40V battery, which they introduced at the same time.
I have the Kobalt system, batteries are the same as Greenworks with a slight form factor but you could make it interchangeable. Kobalt 40V and 80V garden tools are made by Greenworks based in Canada. It's not just about the batteries, 40V tools are toys where 80V are commercial duty. Difference like day and night. 40V maybe OK if your demand is not heavy.
Hello Jesse. Say, I have multiple Kobalt 80v tools which are actually made by Greenworks, one of which came with a silent charger, no cooling fan. Battery gets really warm while charging. This is odd to me. All of my other chargers came with cooling fans and charge with 4 amps. The silent no fan one says 2amps on the bottom label. Which charger will preserve the longevity of the battery packs better? 2 amps and no fan? Or 4 amps with active cooling? Thank you. David
I have two 40 volt batteries, one i just purchased a day or so ago from Amazon, the original battery shows only two green lights , and will not fully charge, can the older battery be recycled or repaired
This is a question for greenworks support.
Call Greenworks, batteries are warranted for 3 years as far as I know.
Yes you can open it and charge individual cells to 4.2v, these gets imbalanced, so you get 2 lights only
The thermal charger pics made me decide against any 40v Greenworks,
and I wonder about 40v/36v licensees.
(For now I expect the 60v chargers would be okay.)
Seems like the weight of the 40 v 2AH battery would be a major consideration when you use it to power a weed trimmer.
Nice to run into this review. I would like to know more on your experience whacking weeds with 40v and 80v trimmers. In replying to J. Wagoner you said "power and efficiency". Efficiency, certainly. I well understand the efficiency of higher voltage (less heat, smaller wires). But in actual use can you further characterize the difference in whacking thick weeds using a 40v vs an 80v trimmer.
Let me add that I just decided to buy a cordless trimmer, but wanted to see if the battery units were "ready for prime time" compared to gas powered units. I went out and bought 5 different brand/models of cordless trimmers to compare. I found that for the weeds I need to trim (coastal scrub in California, which are a bit on the gnarly side) the 40V Greenworks unit a bought did a great job, and the 80V Kobalt unit I bought also did a great job. But in using the two for 10-15 minutes I didn't notice that the 80v unit was all that much more powerful. In other words, I didn't run into any weeds that the 40V could not whack that the 80v could. That's why I'd like to hear your thoughts. :>
Finally, for reasons other than pure whacking power, I fell in love with the 80v Kobalt trimmer. It just was the all round best of the five. As best as I can tell the 80v Kobalt unit is nearly identical to the 80v Greenworks unit, and in fact it is claimed that the Kobalt is just a re-branded Greenworks made for specifically for Lowes. If true, the biggest difference between the two right now may be PRICE. The latest model 80v Greenworks trimmer -attachment capable- on Amazon is a whopping $348 with 2AH battery (www.amazon.com/dp/B00YBFXCMI?ref=emc_p_m_9_b). The 80v Kobalt trimmer at Lowes with the same battery is only $199 (www.lowes.com/pd/Kobalt-80-volt-16-in-Straight-Brushless-Attachment-Compatible-Cordless-String-Trimmer-Battery-Included/50394980.) WOW!!!
I’ve got a review of the 80v trimmer vs a Stihl gas trimmer here: Greenworks 16-Inch PRO 80V String Trimmer Review and Comparison ua-cam.com/video/B7BZRWSc1qY/v-deo.html
I feel pretty silly but we have the 80v and I can’t see an easy way to eject the battery after charging. We end up tapping it on its end with our hands -
trying to encourage it out of the charger. Our hands get sore with this method. Am I missing a release mechanism of some kind? I can’t see an easier way!
Excellent review! Thanks for putting the thought and effort into this. The extra detail you added from your personal use was truly helpful, as was the cooling mechanisms.
I bought the Greenworks 80v snowblower in the hope that I could expand to other devices with 80v batteries. However, I don't see any other devices that use 80v batts from Greenworks.
Mountfield stiga & kobalt use 80v for sure along with other brands....
I use a 200 watt inverter that plugs into my pickup to charge the batteries while on the job site
same here
Great video, much appreciated. Thanks. It's probably been said and I've missed it, but is there an actual power difference between the 40v and 80v systems? My guess would be that if there is it's related to the tool itself, not the battery. We use a couple different Makita 18v impact drivers at work and one model definitely has more power than the other, both using the same battery. I'm leaning toward the 80v simply because I'm guessing it's a little better tool (battery notwithstanding).
the difference in the battery life between those drills is probably that one is a brushless DC motor vs one that is an older style brushed DC motor. The brushless motors are significantly more efficient and will give you more run time and/or more torque from the drill to get the job done.
The 80 volt is a more powerful tool. Have a 40 volt edger. The battery was mia. Bought a CRZ 428 mower. Replaced the 40 volt edger with a 82 volt edger. The 82 volt is a beast. Homeowner not a commercial lawn care user. Like buying from a dealer.
Love the Videos you did on the 80V. You give alot off info that the MFG doesn't. Also, I believe the high amp 80V it taller. I put on some 60V videos and the 60V and 80V are amazingly similar. I'd love to see how quick you can get through a 15in pine with the 80V, I got through in 33sec with a standard chain. It would be a much better estimate of power between the 2 saws.
The big question is what is better the 40 or 80v. I Am not sure if there is much of a difference. Charging yes but not so much performance
Great comparison, answered questions l hadn't thought about.
Loved the whiteboard in the background too 😊
What system do you use for solar charging these batteries.
Can you interchange the batteries on all products? I'm considering the hedge trimmer but noticed the 2 amp battery that is unlike the other Greenworks 4 amp tools I own. Thanks for the video.
Theoretically you can use all the 40v batteries in the 40v tools and all the 80v batteries in the 80v tools, but practically sometimes the 2ah batteries don’t last long enough (80v mower) and sometimes the 4ah batteries are too heavy (80v chainsaw and trimmer).
createthis thanks!

We'd love to see you without the beard! Great review by the way!
Ok, so what I don't understand about the difference between a 40v and 80v setup is does the 80v deliver more power or capacity or both? Debating (with myself) on buying the Greenworks snowblower. Do the 40v and 80v models have the same size motors? Will the 80v just run longer or is it also turning the motor at a higher rpm rate? What's the deal? Thanks.
It’s hard to explain. Higher voltage means greater efficiency with thinner wiring usually. So yes, usually that will translate into more power, greater run times, etc, but a lot of that comes down to the engineering in the rest of the system. If a 40v system and an 80v system perform the same, usually the 40v system will be heavier. Hope that helps.
@@createthisdotcom Som how does that help me decide? Looks like the 80v package doesn't give me much more for the money (assuming they perform the same which I actually have no idea about) other than less weight or am I missing something?
The 80v will usually perform better. If you can afford it, I recommend 80v. Otherwise go for 40v and see if it will work for you.
@@createthisdotcom Performance as in longer or clearing of heavier snow or maybe both?
Yes. Both.
I have the 80 v and the 60 volt battery in the same form factor, do u know if I can use the 80 volt on a 60 v lawnmower?
Pretty sure you cannot.
You should and your mower will run much better but may burnout in time. I would not push it making sure motor not overheated.
Lowe's are selling a 60v products now. Wonder if that's a good compromise over the 80v.
No. For the same power, the higher the voltage, the lower the current; and the lower the current, the lower the overall losses and the better the whole system efficiency.
So, increase the voltage is always a better option.
@creathis : Talking about efficiency, and without any polemics, it seems quite silly to start from gasoline, pass through a generator, converting to a sinusoidal voltage to supply the AC to DC converter (its own charger) to eventually charging the battery. It would be justified only in case of emergency, I mean, if there would be no available utility plug.....
I'd stay away from GreenWorks tool altogether...unless you want all your batteries to die less than a year. I have over 8 of them...ALL DEAD!!! waste of $$$ 80v, 40v, & 24v.
@@svldvc i have 7 tools, and most the batteries are fine. 1 of the 4 batteries i have is starting to show it's age, but that's 4 years old. Not expecting 20 years for a battery.

Thanks great video, but I have a question. My Greeneorks came with a 40 amp hour battery is it possible to move up to a 5 Ah battery?
Yes, they make an 80v 5.0ah battery. I don’t have one, but I’ve seen it listed on the website.
I just got a GreenWorks self-propel mower I think 21in I have 1 40volt gmax 4amp lithium ion batter I’m only getting 30mins roughly of mowing time my yard is lot bigger and need 1.25 more charges to finish would it be worth getting the 5amp for my secondary battery so I can get done hopefully all at once or is it not run much longer then the 4amp and save lil money n just get another 4amp I think price now is around 120 bucks where the 5amp is 180 any advise be helpful
Sorry, I’m not sure. I don’t have the 5 amp hour. I know there was a huge run time boost from the 2 amp hour to the 4 amp hour. I wouldn’t expect the 5 to be that dramatic of a difference compared to a 4 amp hour though.
So my 4 times using my 21in deck self propelled mower 40volt with a 40volt 4apm battery got 30mins first time use 2 time 25 3rd time 16 mins and this last time around only 6mins all on full charge and when I push the light on the battery see what’s left nothing so it’s drained wouldn’t recommend the 40volt mowers from GreenWorks battery is just not cutting it taking me ages to mow my yard with having to always recharge and getting shorter run times each time
I have the 80 V battery two... for my lawn mower... the left battery works however, the right battery will not.. states that it is charged , when I put it in the Charger nothing activated to show charge or complete. When I mow the left battery is fine, when exhausted it should switch to the right battery but NO.... and the Customer Service is horrible.... I will need to return to Costco due to battery issue?
I have several Greenworks 40v tools. Was looking for an extra 4 amphr battery and was confused that the prices on eBay were all over the place with many model numbers referenced. Prices went from $48 to $180. what’s that about?
Do you know the difference between the power of the greenworks 40v chinsaw vs. the greenworks 80v chainsaw. Thanks
Would you happen to know what the run time would be on the 80 V 5 amp hour battery when it is used in a Greenworks Pro 21 in. 80V 3 in 1 Self-propelled Mower
Whats the retail of the 80v 5amp in the US? Here in Britain its a complete rip off at over $500 each! Just not practical when needing 5 of them.
What are good examples of why you would prefer the 80 volt over the 40 volt ( as far as the tool goes) ? I mean why would anyone want an 80 volt weed trimmer?
80v tends to be gas equivalent, in my experience. If you want something slightly less powerful and possibly lighter, go with a lesser voltage.
Hey! How long that 80v battery will last before you have to replace it?
Depends on what you use it for, how you store it, how often you cycle it, etc. If you run the smaller 80v batteries in a high draw application like the mower I have, they will heat up more and probably won’t last as long. However, if you size them properly to the application and store them above freezing you should get good life out of them. Cycle life for lithium ion is a curve and the battery typically is considered to need replacement once the battery is delivering 80% of it’s rated capacity. They typically do that after 300 to 500 cycles. So let’s say you mow your lawn once a week. There are 52 weeks in a year, but let’s say you mow only half of those because winter. So 26 mowings per year, 26 cycles. 300 cycles divided by 26 is 11.5 years! Will they actually last that long? I have no idea. I really wouldn’t bet on it. But they might. That’s what the math says. Mine are all still going strong since I made this video. I see no reduction in capacity. HTH.
@@createthisdotcom Thanks for a reply.
I am trying to buy a greenworks chainsaw. Does it matter which one I buy? There's so many options for it between 40V and 80V. Which would be best?

Is this battery compatible with a powerworks mower?
i was thinking of buying a 80v GW snow blower but not have to rid myself of the 40v line. I wonder how plausible it would be to combine 2 40v batteries in series and use it on the 80v blower? All I would need is a empty 80V casing and some 12G wire.
Probably won’t work, but feel free to try at your own risk and let me know how it goes.
do you compare 40v 4a/h with 80v 2a/h? could not get it. please clarify!
Very Good and Detailed Comparison and Review!! I'm gonna be putting the 40v battery to the test this Winter 🥶 since I just bought the Green works 40v Cordless Snowblower lol
Excuse me if this is a silly question but the higher voltage systems 80v vs 60v vs 40v vs 25v - just means that the batteries charge quicker? Are the actual run times longer or is it more about having extra power and quicker charge time?
+Jack Sassenfeld it's not a silly question. Higher voltage means the wires can be thinner while delivering more power. Basically, lighter and more efficient, but possibly more dangerous too.
Jack, the battery energy capacity actually should be measured in Watt hours. Higher voltage (with the same power) is better for higher efficiency and less heat while working/charging. It also should be noted that in US most sompanies use "mmarketing voltage" while in EU it is nominal numbers that are just multiplied nominal cell voltage (3,6V). So the real world lithium batteries are mostly 18/36/72V.
No. It really depends on the charger. If the 40V battery had a fast charger, it would be just as fast.
Frank W it's a yes and no at the same time. Lower voltage/higher Ah battery will need higher peak and avg. current to charge, causing higher heat emission from (basically) the same cells. This will lead to shorter cell life.
Jack Sassenfeld qetpiutewwď
Thank you very good video.
Do you recommend storing fully charged.
I don’t think that is ideal for lithium batteries, no, but it is what I do.
I have 80 volt Greenworks blower, chainsaw and string trimmer.
glad to hear that-
Incredibly helpful information! Very detailed for sure. Thank you for making this video! Do you own a landscape company? Is that what you use the greenwork line of tools for? Thanks, Riley
No, I’m not a professional landscaper. I just found myself in a situation where I had a bunch of batteries and had used them and thought other people might find it useful to hear my thoughts.
@@createthisdotcom Well thank you for thinking of others and making this video. I just bought a greenworks 80v hedge trimmer kit that came with charger and battery. Bought a backup 4ahr battery as well to go with it. Looking forward to building a tool set that is mainly electric and looks like a greenworks chainsaw might be the next add on ☺️
Yes, the 80v chainsaw is excellent, especially with a replacement Oregon chain and bar. I can’t recommend it enough. Just used it yesterday to trim my Christmas tree. Happy holidays!
Good video but can you dumb down the charge/electricity cost for me? Will I notice a big bump on our power bill with weekly weed trimming with an 80V? And how is that comparable to gas (trying to ignore our current high prices)?
You would have to have either very high electric rates or many of these batteries in constant rotation to even notice a change in your electric bill at all. Electric is almost always cheaper than gas when it comes to tools and vehicles (not so much heat, but that’s a different kind of gas).
@@createthisdotcom Thank you.
On the two 40 volt batteries can I use the same charger for both the 2.0AH and the 4.0AH?
Yes the 2AH 40 volt and 4AH 40 volt batteries use the same charger
hi handsome could you test the enhulk battery system plus kress system? thanks
Does the 40v chain saw perform as well as an 80
Hey Excellent comparison. People need to know what volts and amp hours. Larger volt systems indicates a heavier duty motor., Greenworks Commercial 82 volt systems. Yet another.
How do you charge with solar? Through an inverter or is there a dc to dc means?
For greenworks I think they only offer AC chargers, so always through an inverter.
Thank you. Is there a difference is power between the 40 and 80? I'm asking particularly because I'm trying to decide between the 40v and 80v leaf blower, i.e. would an 80v powered blower be more powerful or not?
80v is definitely more powerful
What difference from original batery and batery pack from alliexpress 80v 4ah ?
Nice technical video, well explained.
As I cannot get information anywhere else I thought I would ask, is there a torque difference in mowers when you use a 80v vs the 40V, Which one has the more power to tough it through thick grass, and also chop up leaves, vacuum leaves?
My 40v mower uses two small blades. My 80v mower uses one large blade. So yeah, there’s obviously a torque differences in the motors, but they’ve designed the lower torque system to do roughly the same work. The 80v is always going to be stronger though. For me it’s more about runtime and cut quality. The 80v mower with the 4ah battery goes a lot longer between battery swaps. And the 40v mower tended to leave a run of uncut grass between the two blades so you had to go over everything twice. I strongly recommend the 80v mower.
@@createthisdotcom I have the newest 40V Kobalt mower (manual push) and it has one blade. Been impressed so far. I think it is relabeled by Greenworks for Kobalt. Super solid deck, wheels, etc. Not so plastic like the Ryobi or earlier versions of the 40V Kobalts.
@@joq702 oh that sounds good. yeah, the original twin force greenworks 40v was pretty bad. it wasn't even brushless. maybe they perfected it.
Is it technically possible to power down an 80V battery to 40 so it can run a 40V tool and if so have you found such a third party converter?
It is technically possible to build such a tool. They’re called buck converters. However, I don’t think greenworks makes one for their own battery systems.
What is the actual running times of the 40 and 80 volt batteries I currently have Ego tools and am interested in getting a pole saw and blowed
Run time depends on the tool.
Which system do you think would work better for a snow blower. I currently use a small corded blower, but would like to lose the cord.
Thanks
If the choice is between a 40v or 80v system, I’d pick the 80v system every time. If cost is not a factor the 80v system will probably perform better.
That said, I hope they aced the waterproofing on an electric snow blower. Seems a bit risky unless they know what they’re doing.
the 40v 2AH battery and 80v 2AH battery both take an hour to charge.. those charge faster than the 40v 4AH battery because they are only half the capacity.. nothing to do with volts
Actual usage life is not mentioned…. The 80 watt betteries last 15-20 minutes in a lawn mower . Takes 2 batteries to cut a very small lawn. Any way to lengthen the actual cutting life of these? A battery hack?
The 80-V 4 ah battery lasts 45 minutes. The newer mowers can hold two batteries and automatically swap between them to provide 90-min runtime.
Could someone please explain the relationship of the volts in the battery to the engine- I would assume that the running time of the 80 volt would be greater than the 40 volt- does the voltage co-ordinate with the engine in any way? for example, doe it increase the rpm's, or the torque, or the performance of the engine in any way? Thanks
Higher voltage just means the wiring can be thinner to deliver the same amount of power. Practically speaking, I think you’ll find that higher voltage products tend to be more powerful because of this, but from a strict engineering perspective that doesn’t have to be the case. It’s just that commercial products tend to be made as cheaply as possible and yet still get the job done. So higher voltage tends to be more powerful.
Which one would you prefer
So, are you saying that the 40v tools are compatible with the 40v batteries? I'm confused.
I said a lot of stuff in the video. Yes, 40v tools are compatible with 40v batteries of the same brand.
Thank you. Answered every question I had.
Additional advantage to higher voltage: higher voltage electric motors are more efficient. Also, for the same work load (Watts), the battery contacts current on the higher voltage packs is less than the lower voltage packs.... Watts = Volts x Amps. This means the battery and tool contacts will last longer... experience speaking :-)
Running a gas generator to charge an electric mower...? seems to defeat one of the big purposes of having battery powered mowers... but that's my opinion.
They just started migrating from 4S to 6S low kv in the racing quad world. Less voltage sag. More efficient.
Please advice! I can not make decision. Here is only 40V and 60V available. I am still very skeptical about battery life in self-prop mouwer as (greenworkstools.eu/cz/en/products/lawn-mowers-gd60lm46hp ) They claim about 80minuts with 4Ah, but there are videos when it run with 5Ah up 20minutes not even high grass.. I have about 1500m2 its like 1/3 acre.. 50% is steepe. I guess a gas mower only my chance.
Great video. I’m looking at a two Greenworks snow throwers. One is a 40V 4AH system smaller unit and can be stored away nicely and not take up room. The other is a 80V 4AH system. A much bigger machine and will take up more room for storage. Of course the prices don’t compare to each other. Reading specs on the units they both seem to have the same estimated run time of 45 min under load. Out of the 2 machines I’m more interested in the actual power performance and how long the machine would operate for? As well as which machine could work through heavier snow. What you think?
What did you go with? Do you still like it?
Thank you for doing this video
Green works has a big issue with having 40v, 60v, and 80v systems. There is no universal charger.once you choose one, You are stuck. At least with other brands. They keep everything the same for the most part. If they want you to go from 20v to 80v. It is really about just adding more batteries to the machine.
The Ah rating is the best measure of battery capacity, not the voltage. An 80v 2.5Ah battery, in theory, isnt going to cut it any better than a 40v 4Ah battery, it's perhaps just a tiny bit more powerful and not that you'd notice in the real world. The 4ah will run hotter as it's a smaller more energy dense battery trying to produce similar power to the 2.5ah (80v).
You cant use voltage as an indicator of power, it doesnt work that way.
As a rule of thumb I've seen that a 4ah battery is the absolute minimum, regardless of voltage, but 5ah upwards is MUCH better. A larger voltage battery will run cooler than a 40V, but you'll still want 4 or 5ah as minimum even with higher voltage.
Which is MORE POWERFUL??!!
charge time doesnt matter to me...so for my new chainsaw the 40 is as good as the 80?
The 80 is always better. Get the 40 if you rarely use it and when you do you only use it for pruning small limbs. Or just buy the 80.
how long do the batteries last?
Not sure how long they actually last. But the warranty is 4 years on the tool and battery
Will the 40 volt 2 amp battery work in a 40 volt 4 amp lawn mower
Yes. My 40V Lawn mower actually came with a 4AH and a 2 AH. Both work fine. (But the 2AH drains much more quickly, which is unsurprising.)
Very thorough and informative video - thank you. Your temperature while charging pics caught my attention, as I just finished reading a review on Amazon from a guy who's workshop caught on fire when he left his Greenworks battery charging overnight. I think I'm going to try and rig a cooling fan to the charger. Have you looked into this?
THANK YOU FOR THE DETAIL INFORMATION.
anyone knows what cells these use internally?
Can I use an 80v battery in a 40v chainsaw green works
No
very informative. Thanks much!
which works best on a mower, 40v or 80v
80 V
the 80v 4ah battery is 2 inches longer
Indeed.
salut mon ami on peut tu prendre une la batterie 80 v et la mettre dans une tondeuse a gazon 40v ?
I assume this is French. Sorry, I don’t speak French.
U never spoke about how long they last while using
That’s because how long they last entirely depends on the tool you are using and the load on the tool. A mower in high grass will kill a battery faster than a mower in low grass, for example.
is not (Watt Hours) a general idea for duration?
@@whyno713 yes, watt hours is a good indication of how long a battery lasts. It's not the only indicator, because sometimes a given battery may handle higher amp loads better than another battery of the same watt hour capacity, but watt hours is probably the best metric we have to compare two battery run times given the same tool.
I thought it was Jesse Pinkman
I really enjoyed your video. I purchased the leaf blower Green works pro and it came with a 60 volt lithium Max battery and then it says 2.5 which of course I don't believe either one of those or this one was not disgusting your video my question is do I want to leave the battery on the charger I do almost as storage and it's always plugged in I was just using it outside and of course I was using high power which I know lessons the amount that I have and then I just started wondering if leaving the battery charger on the charger after it's charged is okay or not okay and I didn't know if the 60 volt batteries charger has a fan in it like you were saying the larger of the two dead that you were explaining about the 80 so I don't know I was thinking about just getting another battery and so I'd have to charge so when I was out there for that 20 minutes and I have maybe 15 more minutes to go I could just switch to a battery that's already charged but they're not cheap yeah actually want the prices I saw I'm almost better off going and getting another one with a leaf blower I mean I want to say that battery was like what 160 and you can get the whole shebang for 199 I know I got a good deal on it that Lowe's but yeah I don't know and I don't know what terms of UA-cam I just agreed to by sending you this message hopefully that's nothing important yeah I just any anything more that you can tell me about the 60 I would appreciate it I do wish they made a battery that could last longer and I don't even know if Green works is made in the USA or somewhere else I honestly I should pay attention more but I didn'tthank you very much I don't know how I'll know that you answered me but I guess maybe try to check back here? I'm the technically challenged one.yeah I just I don't know I didn't want I thought maybe it's damaging the battery by leaving it on the charger I'm hoping that because I've been doing it for about a year just crossed my mind today and I don't know if it's worth trying to get another battery just get a whole another one have a extra leaf blower on me? I will tell you I live in an apartment on the second floor we have outside steps that are always well right now full of leaves and stuff and I used to sweep them and I'm disabled I'm young but I'm disabled and standing for so long isn't as easy as it used to be and I absolutely love the before I mean it really I can hit blow cobwebs or whatever is going on up above me or around the door or it's just a quick easy way and who doesn't love a toy I might be 58 years old but men still like we still like our toys and I knew I wasn't going to want to do a plug-in that would have been a nightmare and this way I can recharge sometimes and go around and hit the neighbors entryways and maybe their patios help clean the blow the leaves out for them. Cordless was definitely the way to go just wish the batteries could be made to last longer wishful thinking I did like the idea of the 80 charging faster I believe yes I got to watch your video again but because yeah let me know on the battery if it's okay to leave it on there if once it's charged I should undo it should I just unplug it from the wall obviously too then hopefully someday I'll have a garage again I hate living in an apartment especially on the second floor but I guess I need some extra size thank you again for your time to my question
Very well described. Thanks for this.
Nice review. Thank you!
You’re welcome!
Hey brother so pretty much the 80v 4.0 is the best one you can get?
For the mower, yeah, it’s pretty good. Too heavy for the trimmer or chainsaw though. I hesitate to say it’s the best as I think there is a 5.0ah battery too and I haven’t tried it.
Hey I own a e bike with a 72v 500w lead acid sealed battery rating can I swap the battery with the 80v greenworks for more speed?
You will have the same performance. It's wierd how all this power tools rate the voltage. These are lithium ion batteries and they use 20 batteries in series with a nominal power of 72v and a maximum power of 82v. I'm not sure why they don't use the nominal power instead. these batteries have the same characteristics of a 72v rated ebike battery
@@twinkletwinklenanastar9500 thanks for the reply man but I'm still trying to see if theirs a cheap way to stop using less acid battery as I need the consistent power of lithium
Marketing
@@User-pc5xe search for "alarmhookup" on Ebay. They sell overstock modem batteries. Build yourself a battery pack. It's nicer that way. If you're a DIY guy, it's perfect
@@User-pc5xe I have bought from them, and they are good quality batteries. And they have so many different options
Lightweight is good and what did I use it for it’s a lawnmower ua-cam.com/users/postUgkxTPN04aT-Qdjr_KS3ql7ng8wnU3wwsCqk also recommend Yes it is lightweight so hence not as robust as our old one. But if you take care it does the job really well.
Do all the batteries fit on all the Greenworks tools?
very helpful. thanx
