If straight from the capacity point of view, 5A does not have advantage against the 2A.. However, after the explanation of how the 5A being configured as 2 rolls of parallel cells, then is a totally different condition. Because of 2 parallel configuration, it allow a higher outflow current loads. Like some of is familiar with Lithium ion battery with the "C" rating, higher "C" value will allow a higher level of current (Amp) flows through. As higher demand tasks, having higher resistance, and required higher torque power to accomplish the task, thus as a result higher load to the motor, and result in draining higher current from the batteries.. all these means, needs higher current flowing out from the batteries to the motor. ;-)
Something that may improve the consistency of your guys' testing would be to pre-drill pilot holes in the testing material. That way, you eliminate the time it takes for the self-feed bits to grab (which seems to be inconsistent at times). Love the channel, you guys make some great content!
As a "DIY'er" home use, is it worth spending the $80 difference on the 5.0ah 2pack or getting the 3.0 2 pack that's on sale? Yard work, occasional 2x4 rough cuts. No long extensive use.
Hi Guys, Yes, it's expected for certain tool to run a little faster between 2.0ah and 5.0ah battery. I think the new idea for faster, cooler and more power on certain cordless tool is by using the new batteries that have the 21700 cells. The regular batteries are running on 18650 cells. Still using larger ah batteries regardless which cells battery does help the performance of the tool. Now in saying that i still like to use the compact batteries for certain task and the same with the larger batteries. Everyone uses these cordless tools differently. With kits now coming with all sorts of different size batteries no one should have a problem with speed or power. If I'm screwing above my head or screwing in cabinets a lighter battery is better. Thanks for the video
Using simple math. A tool grade battery will allow you to draw about 20c. 2*20*20 = 800w. And a 4Ah battery will allow twice that current draw. If the maximum power draw of the tool is less than say 800W, the advantage in power is minimal.
I use Dewalt tools. I like the compact batteries on my impact drivers and sander but I prefer to use the larger batteries on all my other tools. I find the ten cell batteries are more balanced on the drills than the five cell batteries. Nice video.
Yeah a 4/5 Ah battery on the impact drivers doesn't seem to make much difference unless you're driving big lag screws, and it really unbalances the tool. I always use 2Ah on my impact driver
I have the same Makita drill and run it with 3Ah and 5Ah batteries. To be perfectly honest, I don't notice much difference, if any. It's a very powerful tool that I highly recommend. OTOH, my other (brushless) Makita drill rated at half the power of the former does seem to have more juice with the bigger battery. YMMV. Interesting video to watch. Nice to see decent vises on YT. I have 8 in my shop including a Tradesman like yours. Most of the others are heavier duty. Don't get me wrong, it's a killer vise.
that is because the 3ah, 4ah, 5ah and the 6ah have 2 sets of 5 batteries in parallel so double the current and capacity. the 2ah has only 5 batteries in series.
Thank you for this review. I only have the 2ah on my subcompacts, but know if I need more umph, to swap to the 5ah. Also just read your 6ah review and I am about to grab the last pair in the area while they are on sale.
I personally think it depends on the project. To drill just a few holes or drive a few basic deck screws, I think the lighter weight of the smaller battery is worth a few extra seconds of my time. When it comes for heavier duty work, such as larger spade bits, bigger screws/lags,or extended periods, I’d go with the larger size batteries for runtime, and *extra power, depending on application*
The second run is better because the battery is warm. Warm batteries have lower internal resistance. Lower internal resistance means higher voltage/power.
I have dewalt 5.0ah for my jigsaw and reciprocating saw. Smaller 1.5ah (I think? for my drill and small jobs for the impact) I also have a hitachi (I guess now metabo) drill that I replaced the 1.5's with 3.0. I'm really enjoying the Metabo. The feel, performance, etc. Looking at purchasing the Metabo impact (18V) wondering if tbe 3.0 would suffice for homeowner purposes or upgrade to their massive 6.0? I kinda think that huge 6.0 would add a lot of weight and would be more suitable for things like cordless circ saws, mitres,. etc, opinion?
I'd love to see your skid row type application but try it with Milwaukee as the can be a 2.0 vs 5.0 vs 9.0 vs 12.0 and see how they max torque the bolt difference. Also go makita 2.0 battery. That was a rough test that most of us wouldn't do in the field. Good to know
Yeah, the results could be interesting. However, as the differences will have the final dependency of what is the specifications of the motor max load and max toque. If the higher Amp with larger number of parallel cells configurations, (1P Vs 2P Vs 3P Vs ...) beyond the motor max load specifications, it will not going to give any difference ;-)
It's all about discharge rating of each battery. The 5ah may have a higher discharge rate. If the 2ah battery had the same discharge rate they would perform equally. Amp hour rating is how many holes you can drill.
Thank you for the video. I'm in the house where what battery the company supplies the customer with is what you should be testing with. If you add a better battery for the review, then you should have to add the cost of that battery to the product in said review. Thank you again. :)
Thank you for the video and the excellent explanation at the end of the video. Looks like higher Ah batteries not only produce more torque and cuts down the work effort and time it also will last longer since it is less stressed. Thank you again.
It's a property of the battery, so yes it will apply to any tool. If anything, it will be even more noticeable on a saw because it's a very high torque load
I’ve absolutely seen the difference in power between new 2 and 4 amp batteries when removing lug nuts off my truck with an impact wrench. Noticeably faster and easier with the 4 amp. I wasn’t surprised by the test results here. Good test. 👍🏻
When you pull the drill out of the hole, do you reverse the drill anti-clockwise? I think you don’t, but not entirely sure.

Thanks for the follow up test. Many other online tool reviewers know everything and won't admit they might have goofed a little on a test. Suggestion: Could you do a similar test except use batteries of the same configuration but different Ah cells. For example: A Ryobi 3.0 HP vs a 6.0 HP or Milwaukee 6.0 vs 8.0 High Output or just standard 4.0 vs 5.0 2P Battery.

Are all the battery sizes in the same line interchangeable? I thought they were but I grabbed a 5ah to use on my drill that originally came with a ?1.5ah and it didn't want to go on. ?
Does a 40V 2.0AH battery weigh significantly less than a 40V 4.0AH battery? find my Greenworks weed wacker to be quite heavy with a 4 attached and wondered if switching to a 2 would do anything for me.
In fact, this gain is not due to the greater number of energy cells, but to the type of energy cell used in each battery. The 2Ah battery uses 5 Samsung 2000mAh power cells with a maximum CDR of 15A. The 5Ah battery uses 10 Samsung 2500mAh power cells with a maximum CDR of 20A.
I had to 'like' when Clint was humble about not knowing 100th's of a second. It's great when experts in something admit they're not experts about everything. Good video guys
Unlike torque, this is very much dependent on the force applied by the operator. He's not a robot, that force will vary. Not just that, when going into a workout, for example, a certain weight will be harder to push before you're warmed up.
the 3 data points helps to prove the point. Agree a confounder is the fact that he bet the 5ah battery would outperform, therefore consciously or subconsciously he may be pushing harder with that tool. But again the multiple datapoints should help smooth that out. Also, they could have had the timer guy do the experiement too (who bet on a smaller difference). Would be intetesting to see what the difference in speed was with him at the helm. And yes going back and forth between batteries (and warmed up bits) would help. In fact warming up each battery and the bit to start (give each a trial run), then start to measure the time would help eliminate any differences due to 'warmth'. Overall though a neat experiment with an outcome that matches what is known to be true (5ah delivers more power/torque tha n 2ah)
I find the 3,0 amp battery to produce much less dust than the 5,0 amp one... BUT.... You can see much more easily through the holes drilled with the 5,0amp battery which makes this quite a difficult choice. I also noticed the 3,0 amp battery to be somewhat noisier. Now I'm at a complete loss as to what should I go for. Thank you guys for confusing me even more!
Larger batteries prevent voltage drop and have better sustained amperage *flys away* I still use smaller batteries, mostly because it's only a small drop in power and much more nimble. Bust out the large battery when I'm using the hammer drill with a large bit
I have a makita handheld blower. 5ah clearly has more speed and power over the 3ah. Just saying there is no doubt from me. I have many makita tools, but it's the most obvious. You can audibly hear the difference
To see the difference gotta run Milwaukee high draw tools with batteries with 18650 and 21700 cells. There is a difference. They clearly run faster/stronger with 21700 cells
It makes a huge difference. Especially with Milwaukee, just have to have the right version of the right size battery(High Output, Extended Capacity, High Demand, ect.) Dewalt is now in the game with power detect. But they all do it to some degree.
I would like to mention is it worth getting the 5.2A over the 4 and 3 A packs for chainsaw use? as there is huge price difference for the 5.2A Packs. Run time would be important to me here.
I opted for 6 Ah batteries for my Weed Wacker and my pole saw (a small chain saw on a pole for pruning trees). Both came with 1.5 Ah batteries, but due to the length of time on the weed wacker and the load on the pole saw I felt the higher Ah batteries were a good investment.
Good test but I would like to see something more accurate without the variables of arm hand and finger fatigue, micro differences in the pressure applied by the user etc
Like I said good test just interested for my own store of knowledge if higher ah = more power in physical terms not emotive terms...didnt mean to upset anyone
This is the 5th tile project we've done where we've removed the old tile before installing new tile, and the first one with this tool ua-cam.com/users/postUgkxqqoaX03nrziKwF7Bjjcc71YzLEleMvOS . I want to cry for all the unnecessary work we've done in the past. With this tool, we removed tile surrounding a fireplace, as well as the hearth tile, set in loads of cement, in less than an hour. I highly recommend this tool. It was easy to use, and very satisfying watching the tile literally fall off the wall.
Hello everyone , I want to buy the makita Lawn mower DLM431 . In the user manual of this mower its written that i can use only up to 5AH (18v) two batteries. If i use the same battery but with 6Ah do i destroy the lawn mower?
According to my understanding the Ah range stands only for the run time and could not harm the tool if you take higher Ah with the same voltage. But maybe I wrong......For one hand I don't want to harm the mower's engine but on the second hand i really want my mower to work more time.
Ok so between a bosch 18V 1.5ah and 18v 2.0ah Is there any significant difference in life And how long it lasts on charge Like as in 1 hr on 1.5 and 2hrs on the 2.0 I drill knife steel mostly
@Pro Tool Reviews Im looking for new batteries for my Makita products i have drills only at the moment but looking to expand to router, sander, circular saw? As power band & charge time goes 3Ah has served me well. But im concerned other tools will demand more power what do you recomend from 4, 5, or 6Ah for comfortable use time & charge rate used in high drain tools? Ive also seen aftermarket 2.5Ah on the slim profile batteries on ebay which could be useful in a tight spot but dont trust the Ah advertised by the c*****e sellers and the reviews make no sense look copied & pasted. At worst they could be guttless 1.3Ah? For all we know not whats stamped on the tin. Is there a way of testing Ah by loging charge time any info much appreciated to tell me how best to purchase the tools with or without bats for price?
It's not just the Ah, its the amount of cells in a battery. 10 cell (3-6Ah for Makita) batteries can deliver more current than 5cell batteries(1.3-2Ah for Makita)
This will very from tool to tool, battery year to battery year etc.. most companies will use one type of 18650 cells for lower more mass produced batteries then use higher end premium ones in the 5.0 and larger ones. For an average the 5.0 area seem to be the cut off for most companies as to when the use better cells. The better cells will allow for more efficient and quicker power delivery. Jeep in mind that they shop these batteries out yearly so last years battery might have had Sony cells but this years might have Panasonic cells. So while this years battery may be 10% more powerful last years could’ve been equal to or even 20% more powerful. But short of the story.. the rating is in how many amps the battery can deliver in 1 hour so could’ve saved yourself a lot of time and wood and simply used common sense and math lol..
This isn't really an accurate test unless they hook the drill up to a machine that can provide consistent pressure. The inconsistencies in the OSB could also have higher resistance in some areas
don't think a fair test of batteries, should have 2 - 3 brands, most likely a big difference in results, my take. I use 1.5 ah to 5 ah dewalts. milwaukees. thks!
Can't help but wonder how 2AH vs 5 AH batteries effect no-load rpms - measured with some kind of accurate tachometer or strobe. Also wonder if torque can be measured. Some more controlled, repeatable, scientific tests without the variability or subjectivity of humans and without pushing a tool beyond reasonable, normal use. Test the batteries against rated specs. If you need better performance, why not get a better (heavier duty) model tool?
4/5Ah when doing hard work, 2Ah when in the back of a cabinet or the bigger batteries are all on charge... works about as well as I need it to, and means I don't need to pay for half a dozen big batteries I'd also expect the difference to increase as the charge drops - on my electric car there's a noticeable drop in power when at 20% battery vs 100%
Jose Vega Ampere-hour is effectively more runtime. But they got more Ampere-hour not by having better cells, but by putting the double amount of cells in parallel, which mean double available amperage too. Assuming the tool can draw this added power, you get a benefit, but not necessarily double the power as the tool can’t necessarily draw that much current. On bigger tools though, it can be even more of a difference.
No. Ah is a measure of energy storage capacity, not power delivery. Ah x nominal voltage = Wh, higher Wh translates to more total energy storage, and at a given power usage/delivery, that means longer runtime. But power usage/delivery is not fixed. There are two factors involved: 1. Amount of power the cells can supply, sustained and instantaneous. This number typically varies with both Ah (2.0, 2.5, 3.0, etc) rating of the cell, and size of the cell (18650, 21700, etc). Since power is voltage x amperage (aka Watts), and all these batteries are nominally the same voltage, it all depends on how much amperage the cells can sustain. 2. The number of “packs” or “banks” of cells in parallel. An 18V (20V max) LiIon battery in a 1P (single bank of cells) contains 5x 3.6/3.7V cells in series. But those cells (18650) top out at 2.5Ah in they types used for “traditional” (not HP/HO) power tool batteries, because the 3.0Ah and higher versions have lower current/power delivery ratings. So to get above 2.5Ah, you have to either go to a 2P (2 banks of 5 cells in parallel, 10 total cells) or even 3P configurations. Thus, a traditional 3Ah/4Ah/5Ah battery is a 2P configuration with 10 cells. That means it can potentially deliver twice the amperage/power, if the tool can use that much. But since the tool will rarely need/use that much. It also means longer runtime. How much power or speed, will depend upon the specific tool and how hard it’s being loaded. For lighter loads, you might simply get 2x the runtime, but for heavy loads, you might get faster results, and 1.5x-2.0x the runtime. The newer High-Output/High-Performance batteries typically use 21700 cells, these are larger, and can deliver about 50% more current than the 18650 cells used in traditional power tool batteries. They’re also available in capacities up to 4.0Ah, so a 3.0 or 4.0 HO/HP battery can be a “compact” 1P configuration using just 5 cells, while the 2P configurations will be 6.0 or 8.0 Ah, and 3P configurations will be 9.0 or 12.0Ah, capable of delivering very high amperage and power, and/or longer runtimes.
There's too much room for human error here for this to be at all accurate. You should've filmed it with a 60FPS camera and then worked out the time by counting the frames. Could've done that with your phone - probably several hundred FPS. Also, getting a human to randomly drill holes is obviously an issue. You could've used a torque meter to do a very easy and reliable test.
Maybe I should buy a 5Ah battery for my Makita impact to try out, as with my current 3Ah battery it has problems getting the wheel bolts off of my car, although on paper it should have enough juice to do so...
The 3ah has 2 rows of 5 cells, only the capacity is biggeron a 5ah, but maybe the cells are worn out a little and it's having some power loss because of that
@@lukie4ever Well, thanks for the reply, but I don't think they're worn out, as I didn't put heavy use to them...yet. I just have that DTW285 impact and a drill. If the impact is too tiny, well, I'll have to go bigger...(1001 or 1002).
There’s a little problem with the correctness of your experiment. Your manual pressure applied on the drill could vary between between tests. You could be pushing harder on one test or lighter. Not very scientific :)
AH make a huge difference with impacts. My high torque Milwaukee with a 3.0 can barely remove wheel nuts...5.0 it with will with out struggle. A 9.0 will snap the stud off and a 12.0 will clear rip the engine out of the car 😂
A larger battery is not for more power, it is for longer working time. In order to increase the power, you have to increase voltage. A 5ah battery, will run the tool, twice as long as 2ah battery. That means you get more work before a recharge. Its like having your car, half full, or full, of gas. You are not going to get more power out of the full tank, but you will go twice as far.
Most unscientific boring test I’ve ever seen. U can’t redo the test because you’re putting drain on that particular battery. R u sure u guys aren’t painters?
Power = Voltage x Amperage. If the motors are the same they will draw the same amperage, so the only thing you can change is the Voltage to gain more power. Since the voltage isn't changing there are NO power gains. The only thing you get is longer battery life because they're are physically more batteries. You are charlatans and it upset me how popular this sudo- science is. GLWS

a little over twice as long
I agree, thats only half of the test.I think they should have kept going until both were flat.

Great and informative stuff 👍
thank you so much for the information, i am asking if there is no problem operating a 1.3 ah drill with a 3ah battery
Wouldve been great to know how much charge was left in both at the end.
Does a 40V 2.0AH battery weigh significantly less than a 40V 4.0AH battery?
find my Greenworks weed wacker to be quite heavy with a 4 attached and wondered if switching to a 2 would do anything for me.
Thanks for that. Solved a discussion we were having. Nice video too.
In fact, this gain is not due to the greater number of energy cells, but to the type of energy cell used in each battery. The 2Ah battery uses 5 Samsung 2000mAh power cells with a maximum CDR of 15A. The 5Ah battery uses 10 Samsung 2500mAh power cells with a maximum CDR of 20A.
This sounds really interesting
Just getting into makita. I got 4 each 5 aH batteries that came with my kits and a 1 2AH battery.
I had to 'like' when Clint was humble about not knowing 100th's of a second. It's great when experts in something admit they're not experts about everything.
Good video guys
Would there be that much of a difference between a 1.5 and 2 ah battery that would be worth the extra 60 dollars?
Unlike torque, this is very much dependent on the force applied by the operator. He's not a robot, that force will vary. Not just that, when going into a workout, for example, a certain weight will be harder to push before you're warmed up.
And the 2ah weigh a lot less than the 5ah, does that matter?
the 3 data points helps to prove the point. Agree a confounder is the fact that he bet the 5ah battery would outperform, therefore consciously or subconsciously he may be pushing harder with that tool. But again the multiple datapoints should help smooth that out. Also, they could have had the timer guy do the experiement too (who bet on a smaller difference). Would be intetesting to see what the difference in speed was with him at the helm. And yes going back and forth between batteries (and warmed up bits) would help. In fact warming up each battery and the bit to start (give each a trial run), then start to measure the time would help eliminate any differences due to 'warmth'. Overall though a neat experiment with an outcome that matches what is known to be true (5ah delivers more power/torque tha n 2ah)
Can u put time index for all tests ty
I find the 3,0 amp battery to produce much less dust than the 5,0 amp one... BUT.... You can see much more easily through the holes drilled with the 5,0amp battery which makes this quite a difficult choice. I also noticed the 3,0 amp battery to be somewhat noisier. Now I'm at a complete loss as to what should I go for. Thank you guys for confusing me even more!
Can I put 5a on a makita brushless?
It came with 2am but it’s also 18v
yes you can.. amp=runtime, it has nothing to do with power
@@erwinmaes3105 Amp = power output. Amp Hour (Ah) = runtime. A and Ah are NOT the same thing (like miles and miles-per-hour are different)
Should have a regulated pressure, doing it by hand the pressure and speed will vary.
Over 6 runs for each test (24 total), by the same person, it will average out enough that it doesn't really matter: the difference is still stark
Larger batteries prevent voltage drop and have better sustained amperage *flys away*
I still use smaller batteries, mostly because it's only a small drop in power and much more nimble. Bust out the large battery when I'm using the hammer drill with a large bit
Feels like there's some undercover tension between these guys on the banter 😂
I was always told no matter the amps, when volts were the same, the battery would produce the same power output and the amps only determined run time.
Not true unfortunately
I have Ryobi .like to order batteries for it .weedeater what is the longest running battery for it.
That 5.0 on the thumbnail doesn’t seem legit
I have a makita handheld blower. 5ah clearly has more speed and power over the 3ah. Just saying there is no doubt from me. I have many makita tools, but it's the most obvious. You can audibly hear the difference
Same with the impact wrench. Clear difference In power.
To see the difference gotta run Milwaukee high draw tools with batteries with 18650 and 21700 cells. There is a difference. They clearly run faster/stronger with 21700 cells
Same with ryobi hp vs regular 1.5 or 2 ah ryobi makes a hp 2.0 that comes with some tools but i havent seen it sold separately
It makes a huge difference. Especially with Milwaukee, just have to have the right version of the right size battery(High Output, Extended Capacity, High Demand, ect.) Dewalt is now in the game with power detect. But they all do it to some degree.
I would like to mention is it worth getting the 5.2A over the 4 and 3 A packs for chainsaw use? as there is huge price difference for the 5.2A Packs. Run time would be important to me here.
I opted for 6 Ah batteries for my Weed Wacker and my pole saw (a small chain saw on a pole for pruning trees). Both came with 1.5 Ah batteries, but due to the length of time on the weed wacker and the load on the pole saw I felt the higher Ah batteries were a good investment.
It like to see this test done with Milwaukee's high output battery vs the standard. Nice test though 👌
Check out vcgconstruction they have done this already
More Beans = More POWER!
Good test but I would like to see something more accurate without the variables of arm hand and finger fatigue, micro differences in the pressure applied by the user etc
And how would shomthing like that be done? This is a great comparison, you're just nitpicking now
Like I said good test just interested for my own store of knowledge if higher ah = more power in physical terms not emotive terms...didnt mean to upset anyone
If I knew how the test could be done I wouldnt ask the question, I am a mere builder not a physicist tho we are all learning
This is the 5th tile project we've done where we've removed the old tile before installing new tile, and the first one with this tool ua-cam.com/users/postUgkxqqoaX03nrziKwF7Bjjcc71YzLEleMvOS . I want to cry for all the unnecessary work we've done in the past. With this tool, we removed tile surrounding a fireplace, as well as the hearth tile, set in loads of cement, in less than an hour. I highly recommend this tool. It was easy to use, and very satisfying watching the tile literally fall off the wall.
It would help to put the Drill in Reverse when removing it out after drilling through
Lol he understands what the viewers want lol we don’t need all that damn chitchat 😂
I have a Milwaukee 12v vacuum and I can ear the difference with 2 or 4 amp batteries. The motor is louder and a bit powerful with 4 amp batteries.
Hello everyone , I want to buy the makita Lawn mower DLM431 . In the user manual of this mower its written that i can use only up to 5AH (18v) two batteries. If i use the same battery but with 6Ah do i destroy the lawn mower?
According to my understanding the Ah range stands only for the run time and could not harm the tool if you take higher Ah with the same voltage. But maybe I wrong......For one hand I don't want to harm the mower's engine but on the second hand i really want my mower to work more time.
Simple answer No it doesn't affect performance.the mower just runs longer
Ok so between a bosch 18V 1.5ah and 18v 2.0ah
Is there any significant difference in life
And how long it lasts on charge
Like as in 1 hr on 1.5 and 2hrs on the 2.0
I drill knife steel mostly
@@Protoolreviews and u my friend gets a sub
@@Protoolreviews so it is worth it to get a 3ah battery separately since I I usually drill steel
@@Protoolreviews I dont have the money for that and I dont think its available in my country
Thank you very much great test ..Conclusion that higher power equipment needs higher ampere batteries
My generator battery is 12v 15ah 20hr can I sub it for a 12v 18ah 20hr? Does it matter?
@@Protoolreviews 🙏thank you!!
I had this question in my head for a while cool video fellas
@Pro Tool Reviews Im looking for new batteries for my Makita products i have drills only at the moment but looking to expand to router, sander, circular saw? As power band & charge time goes 3Ah has served me well. But im concerned other tools will demand more power what do you recomend from 4, 5, or 6Ah for comfortable use time & charge rate used in high drain tools? Ive also seen aftermarket 2.5Ah on the slim profile batteries on ebay which could be useful in a tight spot but dont trust the Ah advertised by the c*****e sellers and the reviews make no sense look copied & pasted. At worst they could be guttless 1.3Ah? For all we know not whats stamped on the tin. Is there a way of testing Ah by loging charge time any info much appreciated to tell me how best to purchase the tools with or without bats for price?
So now that this is done let's revisit the ryobi vs craftsman with EQUAL ah batteries.
It's not just the Ah, its the amount of cells in a battery. 10 cell (3-6Ah for Makita) batteries can deliver more current than 5cell batteries(1.3-2Ah for Makita)
@@aessu ryobi with a 4ah and craftsman with a 4ah
This will very from tool to tool, battery year to battery year etc.. most companies will use one type of 18650 cells for lower more mass produced batteries then use higher end premium ones in the 5.0 and larger ones. For an average the 5.0 area seem to be the cut off for most companies as to when the use better cells. The better cells will allow for more efficient and quicker power delivery. Jeep in mind that they shop these batteries out yearly so last years battery might have had Sony cells but this years might have Panasonic cells. So while this years battery may be 10% more powerful last years could’ve been equal to or even 20% more powerful. But short of the story.. the rating is in how many amps the battery can deliver in 1 hour so could’ve saved yourself a lot of time and wood and simply used common sense and math lol..
Agreed. However the new 21700 cells in the new 3ah and 4ah batteries are changing that cut off a bit.
Good vid and Nice vises!
NOICE INFO BRO!
Thought this was common knowledge for anyone who used cordless tools.... My 15 year old Makitas made use of this.
This isn't really an accurate test unless they hook the drill up to a machine that can provide consistent pressure. The inconsistencies in the OSB could also have higher resistance in some areas
I was thinking the same thing. Also reflexes to stop start watch over time become more accurate but i appreciate the experiment!
Drill would be negligible, you needed something like a belt sander
If you focus on his thumb for the stop watch. He’s slow to react to the actual driver start.
Konsistant Kenny needs to lighten up
Очень интересно 👍
Very good test .
don't think a fair test of batteries, should have 2 - 3 brands, most likely a big difference in results, my take. I use 1.5 ah to 5 ah dewalts. milwaukees. thks!
Can't help but wonder how 2AH vs 5 AH batteries effect no-load rpms - measured with some kind of accurate tachometer or strobe. Also wonder if torque can be measured. Some more controlled, repeatable, scientific tests without the variability or subjectivity of humans and without pushing a tool beyond reasonable, normal use. Test the batteries against rated specs. If you need better performance, why not get a better (heavier duty) model tool?
Ah=runtime.. Nm=power
4/5Ah when doing hard work, 2Ah when in the back of a cabinet or the bigger batteries are all on charge... works about as well as I need it to, and means I don't need to pay for half a dozen big batteries
I'd also expect the difference to increase as the charge drops - on my electric car there's a noticeable drop in power when at 20% battery vs 100%
Not a well constructed test.
Some are off angle and so have to travel further and the pressure applied is not controlled.
What's up with you guys. Someone pissed in Kenny's coffee that morning.
You have one job😁
... way didn't you used the handler ? It's given you more advantage
Doesn’t Ah only increase runtime not power.
No, this test proves that larger batteries can supply more power to the tool.
Jose Vega Ampere-hour is effectively more runtime. But they got more Ampere-hour not by having better cells, but by putting the double amount of cells in parallel, which mean double available amperage too. Assuming the tool can draw this added power, you get a benefit, but not necessarily double the power as the tool can’t necessarily draw that much current. On bigger tools though, it can be even more of a difference.
No. Ah is a measure of energy storage capacity, not power delivery. Ah x nominal voltage = Wh, higher Wh translates to more total energy storage, and at a given power usage/delivery, that means longer runtime. But power usage/delivery is not fixed. There are two factors involved:
1. Amount of power the cells can supply, sustained and instantaneous. This number typically varies with both Ah (2.0, 2.5, 3.0, etc) rating of the cell, and size of the cell (18650, 21700, etc). Since power is voltage x amperage (aka Watts), and all these batteries are nominally the same voltage, it all depends on how much amperage the cells can sustain.
2. The number of “packs” or “banks” of cells in parallel. An 18V (20V max) LiIon battery in a 1P (single bank of cells) contains 5x 3.6/3.7V cells in series. But those cells (18650) top out at 2.5Ah in they types used for “traditional” (not HP/HO) power tool batteries, because the 3.0Ah and higher versions have lower current/power delivery ratings. So to get above 2.5Ah, you have to either go to a 2P (2 banks of 5 cells in parallel, 10 total cells) or even 3P configurations. Thus, a traditional 3Ah/4Ah/5Ah battery is a 2P configuration with 10 cells. That means it can potentially deliver twice the amperage/power, if the tool can use that much. But since the tool will rarely need/use that much. It also means longer runtime. How much power or speed, will depend upon the specific tool and how hard it’s being loaded. For lighter loads, you might simply get 2x the runtime, but for heavy loads, you might get faster results, and 1.5x-2.0x the runtime.
The newer High-Output/High-Performance batteries typically use 21700 cells, these are larger, and can deliver about 50% more current than the 18650 cells used in traditional power tool batteries. They’re also available in capacities up to 4.0Ah, so a 3.0 or 4.0 HO/HP battery can be a “compact” 1P configuration using just 5 cells, while the 2P configurations will be 6.0 or 8.0 Ah, and 3P configurations will be 9.0 or 12.0Ah, capable of delivering very high amperage and power, and/or longer runtimes.
There's too much room for human error here for this to be at all accurate. You should've filmed it with a 60FPS camera and then worked out the time by counting the frames. Could've done that with your phone - probably several hundred FPS. Also, getting a human to randomly drill holes is obviously an issue. You could've used a torque meter to do a very easy and reliable test.
Maybe I should buy a 5Ah battery for my Makita impact to try out, as with my current 3Ah battery it has problems getting the wheel bolts off of my car, although on paper it should have enough juice to do so...
The 3ah has 2 rows of 5 cells, only the capacity is biggeron a 5ah, but maybe the cells are worn out a little and it's having some power loss because of that
@@lukie4ever Well, thanks for the reply, but I don't think they're worn out, as I didn't put heavy use to them...yet.
I just have that DTW285 impact and a drill.
If the impact is too tiny, well, I'll have to go bigger...(1001 or 1002).
@@wiedapp i have the makita ripoff from that dtw drill lmao
There’s a little problem with the correctness of your experiment. Your manual pressure applied on the drill could vary between between tests. You could be pushing harder on one test or lighter. Not very scientific :)
AH make a huge difference with impacts. My high torque Milwaukee with a 3.0 can barely remove wheel nuts...5.0 it with will with out struggle. A 9.0 will snap the stud off and a 12.0 will clear rip the engine out of the car 😂
Mean O’ Dustino I have the 2767 and have only used it with a XC 5.9 so far haha
Not true
NOT A REAL TEST, HE HAND PRESSURE IS DEFFRENT
6:48 😂😂😂
Not accurate. Because if you push hard on one example and less hard on the other you will have different result.
10:00
The higher amp batteries shine at max loads. Not this drilling nonsense
Thats a lot of money your wasting in wood.
A larger battery is not for more power, it is for longer working time. In order to increase the power, you have to increase voltage. A 5ah battery, will run the tool, twice as long as 2ah battery. That means you get more work before a recharge. Its like having your car, half full, or full, of gas. You are not going to get more power out of the full tank, but you will go twice as far.
Most unscientific boring test I’ve ever seen. U can’t redo the test because you’re putting drain on that particular battery. R u sure u guys aren’t painters?
Power = Voltage x Amperage. If the motors are the same they will draw the same amperage, so the only thing you can change is the Voltage to gain more power. Since the voltage isn't changing there are NO power gains. The only thing you get is longer battery life because they're are physically more batteries. You are charlatans and it upset me how popular this sudo- science is. GLWS
