Great video - given the assumption that OEMs will always be "the best option" it's nice to see what's best of the 2nd option (3rd party). As long as these cells are safe, it's almost a no-brainer. With shipping a new OEM Dyson V8 batt is $150 including shipping from Dyson. That's almost half the cost of a NEW V8. Even if one of these $30 replacements were to fail, you could "fail" 5 times before you reached the cost of the Dyson batt. This is not convenient or eco-friendly but that means the replacement needs to have the longevity of about 1/5 the OEM price parity. You can't tell me that Dyson is not overcharging for their replacement packs. I don't expect them to be cheap but at least not exorbitantly overpriced. Again, thanks for this vid.
Dyson is definitely charging a premium for their battery packs, that is for sure. While they are the best made packs available, it is nice to know there are some decent replacements on the market if you shop the right models. I'm glad this helped!
Fantastic review. Wish you tested more batteries, but I understand you pay for them out of pocket. I would love to see more non-vacuum videos from you. Batteries for power tools, solar lights etc. Your work helps us mortals tremendously. The sellers are just so incredibly deceptive. As far as the amperage rating from what I have learned from other youtubers is that it's a wild west and you can state whatever you want with no legal repercussions.
Glad you enjoyed the video! The battery choices certainly don't remain evergreen, so I'm sure I will be testing more in the future (likely a selection of eBay replacement batteries). Interesting idea on testing the other battery applications out there. I'll have to keep that in my back pocket! Thanks for watching!
I just watched this video today, and unfortunately cannot locate either the DutyOne or the Tenhutt on Amazon. Do you have a current recommendation? Thanks so much.
Couldn't have said it better myself! OEM is always the most reliable option, but replacement batteries can really be a gamble. But if you get lucky with a good one, it can save a lot of money... decisions, decisions! Thanks for watching and commenting!
From my experience, it's the opposite. Purchased V8 in Nov 2018. By Aug 2020, OEM battery was dead (a minute or two if we were lucky). I purchased a Lasica aftermarket from Amazon and replaced it in Aug, 2020. It's been 3 years and it's still going. It's still giving about 6 minutes of use as opposed to the close to 10 so I'm considering replacing it. So in my case, the OEM was a dud in under 2 years.
Thanks for your extensive effort on these reviews. 10C on a 3AH cell would be 30A, not 20A. One thing we've discovered is many so called "nickel strips" are not solid nickel, but are nickel plated iron. Since both nickel and iron are magnetic you can't tell with a magnet. You can tell with a corrosion test as nickel won't rust but the plating makes it difficult to test the interior of the strips. The plated strips have more resistance and this adds to the heat generated and reduces the energy delivered to the vacuum motor. Nickel is quite expensive. So when a cheap pack has nickel strips, I wonder if they are real...
I think that in the name of the environment and recycling, these battery packs should be able to have rechargeable batteries that can be just slot in when the old ones have died just as you would do with a torch. All these battery packs use these 3.2 volt batteries which are easy to acquire and depending on the brand are better or worse
Liability of a customer using an underrated cell and causing an explosion will likely keep that from happening, but your point is well taken. Battery powered items do have a shorter expected life overall and will contribute more waste and pollution with cell chemicals. Everyone should always recycle their lithium ion batteries either at their local municipality or BatteriesPlus or a similar retailer. Thanks for commenting!
I mean the cells in most battery packs are pretty replaceable if one has a decent set of tinkering skills -except Makita, eff those guys- so chances are even if you don't have those skills, someone in the family should.
You have a good point. You shouldn't have to replace the battery casing, the electronics, and the charging port, just because cells are dead. but it keeps profit high for them since it makes it more complicated to source a battery with similar quality of electronics, and good cells. unfortunately, batteries are often just marketed on their capacity. I would gladly buy a third party battery pack with removable cover and easy to swap cells. does everything really have to be glued/soldered?
Hi Albert! I did test the V8 battery at 2:01 . However, I did not disassemble the OEM battery because we already know what cells it is using, which is the Sony/Murata 21700 VTC-6. It is a top shelf cell. Hope that helps. Thanks!
Very well done and informative video. I would be interested if you have tested the POWTREE Upgraded 6.0Ah V8 SV10 Battery 215681 Replacement Compatible with Dyson V8, against the FORMIKO 6.0 Ah 21.6V Lithium Battery Replacement for V8. Both seem to have high ratings and the lowest #1's.
I'm repacked my dyson v8 battery using molicel p42a 21700 cells, they have a 45 amp discharge, 4200mah capacity, they are 1mm larger in size, so you have to sand the inside a little bit, not a big problem though. The battery runs much cooler. I'm able to get 70ish minutes on low power, 15-20 minutes on max.
@@HouseOfVacuums I'm getting 60-70 minutes on low power, and 15-20 minutes on max. I'm working on a 3d printed shell using the original bms, but with a 2s6p configuration, so in total 12 cells with a total capacity of 8400mah at 21.6 volts, you would need a better charger though, my p42a battery takes about 4-5 hours to full charge, isn't too bad but 8-10 hours would be horrendous with the 8400mah config, I might buy a 6s 100 watt charger to charge faster. Wish these kind batteries were sold on amazon, the quality you get from 3d printing is never as good as injection molded plastic.
I bought the Dutyone May 2021. It worked great for all of 8 months!! Then it DIED completely while on the charger!!! I went to use it and it was DEAD. Arrrrgh!!! Total waste of money!
hi i bought two 8v batteries from amazon replacement li-ion tool battery for my dyson v8 animal plus. one worked a day and stopped. if you plug it inn the blue green light stays on but dosnt charge up. i will look up the batteries you said thank you 🙂
Hi Lea! The link to the DutyOne is in the description, however it has been out of stock for a little while. My second choice in the comparison would be the runner-up, the TenHutt which can be found here rb.gy/hpzxok. The FirstPower in this comparison did not test nearly as well. I hope that helps!
Hello thanks for the video, I have a question, was the battery test performed with the Power head (Carpet) attached and operating or was it only the tube itself. That would change results drastically. Would love to hear back. Thanks again.
Hey Scott! Because of my video, the DutyOne is unfortunatley often out of stock. I would say the FirstPower would be my second choice, and you can find that here: www.amazon.com/FirstPower-5-0Ah-V8-Replacement-Battery/dp/B08F2LVTN8/ref=sr_1_6?crid=O3OCCPGHAYN4&keywords=tenhutt+dyson+v8&qid=1670691819&sprefix=tenhutt+dyson+v8%2Caps%2C60&sr=8-6
What do you think of the batteries on Ebay? Some of them say they are powered by Sony cells. I was thinking about it to save a buck. Would love your feedback on them.
Great catch, I miscalculated! The correct formula would be (3.0Ah * 10C = 30 Amp Burst). 10 C does differ a little bit from maximum discharge rating, though. The C rating is the burst rating for a very short period of time, the max discharge is the maximum draw a battery can withstand over the entire discharge... so we still don't know if this battery can handle be on high for the duration of a Dyson V8s runtime. Thanks for pointing that out!
Hey Mike. It's apparently doable, but I'm not good at it. The cases are pretty mangled by the time I get through with them. The best advice I can give is work slowly on the seam with the smallest screwdrivers you can find. Cheers!
Thanks for watching! The recommended DutyOne is currently out of stock (no doubt COVID supply chain issues). Without that one available, I would recommend the runner-up, the TenHutt rb.gy/r38xx7. Hope that helps!
Bought a 5000mah aftermarket battery on ebay and they came broken, the battery just not usable (when charge it, nothing happened, when put them onto the vacuum nothing happened as well) they resend a new one, and i opened up the broken one and nothing seems out of place or burned is anyone has any idea?
Batteries on eBay are notoriously sketchy and I'll probably do a video on them eventually. In the meantime I would stick with the recommendation in this video or the OEM as your safest bets. Thanks!
Absolutely! The DutyOne has been out of stock for a while... likely due to the current global supply chain issues. While it is unavailable, I would recommend the TenHutt as a second choice. While it doesn't have name brand cells, it is constructed extremely well and performed well in the test... only slightly behind the DutyOne. smile.amazon.com/gp/product/B07QG5NMWN/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
such a great review! ONLY problem is the DutyOne is available NO WHERE. Amazon out of stock and not getting stock so i'm stuck looking at all the other replacement batteries that you didn't recommend. after reading reviews just about all the others have bad reviews after using for a month or more. :( so lost on what to get. Any other recommendation?
Thanks for the question. Yes, the DutyOne has been out of stock for a little while now due to supply chain issues. Another option is the TenHutt from our test. It tested very well and was a solid build. You do give up the name brand cells from the DutyOne, but the TenHutt would certainly be my second choice. Thanks!
Hi Bryan! It seems the DutyOne I recommended is currently out of stock. Because of this, I would recommend out runner-up, the Tenhutt. It didn't win the competition, but I think it is a solid runner-up for the price. rb.gy/r38xx7
@Bryan Young in my testing, the TenHutt beat the OEM battery in terms of runtime. If you are talking about overall life of the battery, it is exactly like OEM where it is the luck of the draw. The best way to protect the battery is to wait 20-30 minutes after using to recharge it. Also, don't let it stay on the charger for days on end. That will help with battery life. Thanks!
Unfortunately no. I will have a V7 battery comparison coming out in the next 4 months or so, but I know that doesn't help right now. I would stick with a battery made by Tenhutt or just get the OEM.

I have not tested the DutyOne long term. Looking at the reviews, my guess is going to be that the PCB doesn't handle continuous charging well. Really, that should be avoided in pretty much any lithium battery pack, but some handle it better than others. My review is really to determine 1) which one lasts the longest, 2) which has the best cells and 3) whether or not the manufacturer is overstating capacity. But like I said in the video, I'm not an electrical engineer who can determine the quality of the PCB, so if reliability is more important that price, the best option is always the OEM battery. Hope that helps explain where I was coming from. Thanks for watching and commenting. Cheers!
Your right, and typically I wouldn't recommend Sunpower because of a lack of documentation. But for a 3000mAh 21700, 10C is on the low end of what that form factor is capable of, so I feel pretty confident they are up to the task. Hope that helps!
Great review, thanks for taking the time. Well done sir. I bought a battery from amazon, the brand was battool. It worked well about 3 times, now will not power. I would be up for sending it to you (my dime of course) to take apart to do your thing. If you would like, comment here and we will figure out how to make that happen
Hey, thank you for the thought and sorry for the delayed reply! I'm sure you have disposed of it by now, but I appreciate the thought! What did you replace it with?
When doing the battery prices ,just round up the prices insted of saying $19.99 , just say $20.00,Thank you ,grest video :I have just gotten one step closer to being the smartest man on Earth
Ordered a replacement battery with stated power of 8000mAh vs. the dyson’s 2800mAh and 21.6V. QUESTION: do I face any issues with such a higher power output?
Great catch, I miscalculated! The correct formula would be (3.0Ah * 10C = 30 Amp Burst). 10 C does differ a little bit from maximum discharge rating, though. The C rating is the burst rating for a very short period of time, the max discharge is the maximum draw a battery can withstand over the entire discharge... so we still don't know if this battery can handle be on high for the duration of a Dyson V8s runtime. Thanks for pointing that out!
I cross reference that number with the available batteries for Dyson models and didn't come up with anything. There are for any Dyson V8 that takes battery part number 967834-08. I hope that helps!
I use a Dyson V8 with a Dewalt battery attachment. One 6 amp battery last 3 times as long as the original Dyson battery. If that ever went dead put in another 6 amp battery. I have 6 Dewalt batteries.
I definitely want to test out some of those adaptors. The couple of potential issues I see would be a lower voltage resulting in poorer performance as well as issues with the low voltage cuttoff not being accurate... I just haven't gotten around to it yet. Glad it's working for you!
@@HouseOfVacuums I asked the same thing knowing Dyson is set for 21.6 volts and dewalt is 20v, but I knew dewalt isn’t exactly 20v it’s always a little more. Together with 5 and 6 amp batteries the voltage stays at that rate. Dyson being around only 2 amps the voltage drops to 20 when using it. So I said I have to wait to try it and it worked fine like I thought.
I'm not 100% sure, but it may be that it isn't able to fully get to the 25.2V charge due to a weak cell, which would cause an error. Is the battery still running a decent amount of time or has it become weaker?
What people don’t understand is there’s only a few 18650 cell maker’s… Samsung, LG and Sony. For high drain Sony VTC6’s are the best!!! Off brand batteries are just re-wrapped Samsung, LG and Sony’s. If it’s high drain it’s almost definitely a green wrapped Sony VTC5A or VTC6 or VTC6a. Ohhh they’re using 21700 batteries… better than 18650 for power but not as tested as the 18650 cells, but the Sony 18650 VTC’s can handle 30a continuous load rather well, but when ran in parallel it reduces the amp load on each cell. If you take off the wrap it should have a number batch stamp if they’re Sony’s. If it’s a mechanical switch they probably have a mosfet chip to control temperature. All batteries are rated like D to A+ in grade. All the A+ rated cells go to big OEM companies like Dyson for example… that demand high quality and consistency. You can add more batteries to cut the load on each cell
The big 4 cell manufacturers are Samsung, LG, Murata (formerly Sony) and Panasonic/Sanyo. That being said, there are a fair number of Chinese and Taiwanese companies that make their own cells like EVE, Sunpower, Hunan Prospower, Molicell, etc. They are actual manufacturers and not rewrappers. I think the rewraps you are referring to are the vaping specific brands like Efest, Vapcell, Imren, etc. They are most definitely rewrapped, lower binned units. The most sketchy of them are rewraps of binned cells from companies like Sunpower and Hunan... the stuff nightmares are made of. Thanks for watching. Cheers!
To my knowledge, yes. Unfortunately, these battery manufacturers and the version of their batteries change on a frequent basis, so it is possible there is something better out there but I haven't tested it. I'll have a follow-up test of some new models in 3-6 months as an update. Cheers!
Very disappointing that a £250 hoover has a battery that lasts little longer than 15 months! Mines still under warranty so Dyson sent a replacement but no doubt I'll be in the same boat in 15 months time. Put me off buying another Dyson
don't keep it plugged into the charger 24/7 it kills the battery since lithium ions degrade when fully charged and kept fully charged. get a timed outlet or a smart outlet and set it to charge for a couple hours or more depending on usage and then power off. it does suck that the charging IC doesn't have that built in tho. but personally no other vacuum holds up to the dyson imo
I hear you. While Dyson is certainly the most ubiquitous cordless vacuum brand, these issues aren't unique to them. It comes with the cordless category in general. While some product segments like power tools have MUCH higher quality battery management, there literally isn't a single cordless vacuum manufacturer that has gone to those lengths to protect the battery cells. Because the bar is so low for consumer electronics, I don't see that changing any time soon. Thanks for watching and commenting!
@@dylan-nguyen i have a v8 and was looking online and it said it was safe to keep them plugged in so it’s better to not keep them plugged in 24-7 I just want it to last and have as much life cause I paid like 400$ for this thing and it’s great.
Thanks for this video. I just replaced the OEM with the new one a Powtree that I bought from Amazon before I saw your video. The battery I bought says on their product description to use the original dyson charger. When I plugged it in to charge the battery the blue lights do flash even though it appears the charger doesn't insert fully into the port. It's hard to tell by sight because of the plastic housing that surrounds the port. Do the blue lights flashing mean that the battery is getting fully charged? Should I be concerned about the charger not appearing/feeling like it is fully inserted? Or should I buy a different charger for the replacement battery? Thanks for your help.
With barrel port chargers, it can sometimes appear that they are not all the way in when they actually are. As long as the light is flashing blue it is getting voltage and charging. Depending on how they circuit board is controlled it will either turn off that light or shine constant blue once completely charged. But I don't see a reason why you would need a new charger since there is voltage getting to the battery. I hope that helps!
The best option is to not buy any of these batteries. Instead buy a battery adapter for the any of the Milwaukee, dewalt etc batteries. I can run my v8 animal on normal with a Milwaukee 5ah for about 40 minutes and about 12 mins on turbo.
The dewalt batteries don't have a built in temp cutoff which as you saw in the comparison is what is saving the batteries from burning up. Also If you use the adapter you shouldn't drain the battery completely so that it doesn't get damaged. Lastly, they may discharge more quickly when left connected. This happened to my old dewalt 18v(nicad) drill with official dewalt adapter for use with lithium batteries. I can't say the same for milwaukee batteries though.
Yes, with supply chains still being a mess I think they are diverting all their new batteries to building new machines. It's unfortunate the genuine batteries are so hard to come by.
Even if the batteries inside had the brand and model number, it means nothing as most batteries are fake from china, some the capacity maybe correct but doesn’t mean the brand is genuine and the rest of the spec is accurate, I bought many cells that claim to be Panasonic or Sony or LG but most are fake, some have real capacity but are not genuine still, so even if the brand and model number is on the cells, it means nothing. Best to build your own battery with cells
True for name brands, but there isn't any reason to fake already Chinese cells like BAK, EVE, Sunpower, etc. These video aren't to prove that one is awesome, it is more to show that most are pretty terrible.
@@HouseOfVacuums yh I understand that part, I was just telling you my experience as I buy lots of cells, obviously china only fake the decent brands and no reason to clone a china cheap brand, I just have tested batteries from 10 different suppliers and near enough everyone was either fake capacity and or fake brand like LG, Panasonic or Sony etc
Dyson has been known to make parts scarce... but in this case I really think it was the supply chain issues the last 2 years. The chips used to control the batteries were impossible to find for a while, so it unfortunately wasn't just a Dyson problem. That being said, I also distrust Dyson's part availability in general. Cheers!
Fair, but you'd think with the YUUUGE margins Dyson has with the price of their packs, they'd have a bit more leeway to bump up the offer prices to their suppliers so'd they'd be near the front if the line...
You can... it just takes some special steps. The PCB will lock up forever if you remove all voltage from it, so you need to be able to provide 12-24 volts-ish in parallel with the existing cells prior to removing them. Then you need to attach them, which is best accomplished with a high amperage battery cell spot welder. You can solder it, but that prolonged heat can damage a new cell... end you right back where you started. Thanks for watching and commenting!
@@HouseOfVacuums In my experience this is not entirely true. I have recently rebuilt two different (ZH2, VE6) V8 batteries with new cells. Having the rumoured need for a parallel voltage supply in the back of my had I tested the OEM-Pack by disconnecting and reconnecting the nickel strips first. The pack worked just fine after that. Note that the battery does not put out any meaningful voltage outside the vacuum regardless of pushing the little switch. To test the functionality (of your partially disassembled battery pack) you actually have to slide it into the vacuum (mind polarity!). If the battery works, the vacuum will turn on (without pushing the micro-switch). I have also found that it is possible to loose functionality if you disconnect (and reconnect) one or more of the middle voltage sensing strips. I could regain functionality be disconnecting and reconnecting the main positive afterwards. This apparently resets the battery management system on the PCB. When rebuilding my two packs both PCBs would sit on the bench without any cells for days. Reconnecting the cells I started with the main negative and connected the strips in ascending order finishing with the main positive. Please note that this job is far out of scope for layman. I would not recommend it due to electrical and fire hazards involved and the need for a spot welder. It is even extraordinary difficult to open the packs without damaging the plastic cover.
Very interesting, thanks for the information and the detailed explanation. It is good to know that it can be rebuilt without the need for parallel voltage if the need arrises. One of these days I'm going to "hot rod" one of these batteries with higher capacity cells, so this is great to know. Cheers!
There are many that don't work very long, whether it is cheap cells, a cheap BMS or both. Hopefully these videos help narrow down the ones that have the best chance of lasting longer than a few months. Thanks for watching!
That's why I take them apart; Amazon reviews are notoriously unreliable. There are certainly negative experiences with replacement battery packs, so if you are ever uneasy about their safety, it is always better to get the OEM battery pack like I stated in the video. Hope that helps!
Why do you think these have literally doubled in price in less than 2 years and EVERY one of THOSE big vacuum makers have made an inferior copycat one of THESE! You can go wrestle with that Kirby if you want but I’ll pass because this has proven to actually clean better.
Sadly these reviews don't last for long... the brands change like the winds and disappear after the companies run out of supplies for their manufacturing runs
Part of my selection process is to look for "brands" that have a history of sales on Amazon. For instance, TenHutt, FirstPower and DutyOne have all been around a while. Unfortunately, the DutyOne seems to have run into supply chain issues... so we'll see what happens there. Thanks for the comment!
Hmmm, never stated that they were Dyson units... they are replacements which is common in many industries. Do you think the mechanic that uses Fram oil filters on your car instead of Honda, Toyota, etc. is encouraging fake goods and a hypocrite? Seems like you are a little worked up over a vacuum battery video there, bro.
I bought a homesuit 4600mah battery. We're used. 5 month, but i think max. 10 work hours. Yesterday didn't work more. One of the 6 battery is failed. I replaced to a 2000mah this one, and alive again. I haven't capacity tester, but i have the battery type code: PROS18650 F2 3.6V 23E182Y10 I didn't found any information, about this battery, but if you find it, you have information about another one company (and pls write me also).

As far as the amperage rating from what I have learned from other youtubers is that it's a wild west and you can state whatever you want with no legal repercussions.

Very well done and informative video. I would be interested if you have tested the POWTREE Upgraded 6.0Ah V8 SV10 Battery 215681 Replacement Compatible with Dyson V8, against the FORMIKO 6.0 Ah 21.6V Lithium Battery Replacement for V8. Both seem to have high ratings and the lowest #1's.
Great review, exactly what I needed!
Glad I could help!
thank you so much for the review and sharing
Thank you for doing this for us. I appreciate you.
Have you ever used one of these replacement batteries in you V8? Or do you have a nightmare Dyson battery story to share? We'd love to hear from you!
I'm repacked my dyson v8 battery using molicel p42a 21700 cells, they have a 45 amp discharge, 4200mah capacity, they are 1mm larger in size, so you have to sand the inside a little bit, not a big problem though. The battery runs much cooler. I'm able to get 70ish minutes on low power, 15-20 minutes on max.
@@Iinustechtips Molicel P42a are great cells! Good choice. I'd be interested in hearing the runtime results/temps you experience.
@@HouseOfVacuums I'm getting 60-70 minutes on low power, and 15-20 minutes on max. I'm working on a 3d printed shell using the original bms, but with a 2s6p configuration, so in total 12 cells with a total capacity of 8400mah at 21.6 volts, you would need a better charger though, my p42a battery takes about 4-5 hours to full charge, isn't too bad but 8-10 hours would be horrendous with the 8400mah config, I might buy a 6s 100 watt charger to charge faster. Wish these kind batteries were sold on amazon, the quality you get from 3d printing is never as good as injection molded plastic.
@@Iinustechtips I am in the process replacing battery in my v8. Do you need to sand inside of the container in order to put 21700? Thanks
I bought the Dutyone May 2021. It worked great for all of 8 months!! Then it DIED completely while on the charger!!! I went to use it and it was DEAD. Arrrrgh!!! Total waste of money!
neither is availble now, any updates? tx
hi i bought two 8v batteries from amazon replacement li-ion tool battery for my dyson v8 animal plus. one worked a day and stopped. if you plug it inn the blue green light stays on but dosnt charge up. i will look up the batteries you said thank you 🙂
Educational and lawyer like in the review. Excellent work and helpful.
Happy to help. Thanks for watching!
How do you attach it?
Nice job, a real service, thank-you. I would never buy a Dyson again!
Glad to help!
Can you supply the link to buy the Dutyone and Firstpower
Hi Lea! The link to the DutyOne is in the description, however it has been out of stock for a little while. My second choice in the comparison would be the runner-up, the TenHutt which can be found here rb.gy/hpzxok. The FirstPower in this comparison did not test nearly as well. I hope that helps!
Thanks for your honest review.
Happy to help. Thanks for watching and commenting!
Hello thanks for the video,
I have a question, was the battery test performed with the Power head (Carpet) attached and operating or was it only the tube itself. That would change results drastically. Would love to hear back.
Thanks again.
Hey GTR! The test was performed with the carpet power nozzle attached since that is most common use case. Hope that helps. Thanks!
It doesn't really matter since they were all tested the same, you can tell which battery lasts longest.
Just the video I was looking for 👏🏼 thank you 🇸🇦
Glad I could help!
Can you recharge the battery while not on the vacuum?
Yes, you sure can!
I am having trouble finding the Duty One battery on the internet, do you have any suggestions ordo you know where I can get one?
Hey Scott! Because of my video, the DutyOne is unfortunatley often out of stock. I would say the FirstPower would be my second choice, and you can find that here:

Great review, helped me make a smart decision
Great, glad it was helpful, Kevin!
thank you for a job well done on my questions.
Happy to help!
Both top batteries are unavailable now -_-
What do you think of the batteries on Ebay? Some of them say they are powered by Sony cells. I was thinking about it to save a buck. Would love your feedback on them.
I personally have not had any experience with eBay battery packs, so I would be hesitant to recommend them. Maybe a new video series idea? Hmmmm.
5:17 would a 10C rating not mean 30 amps or have I got that wrong
Great catch, I miscalculated! The correct formula would be (3.0Ah * 10C = 30 Amp Burst). 10 C does differ a little bit from maximum discharge rating, though. The C rating is the burst rating for a very short period of time, the max discharge is the maximum draw a battery can withstand over the entire discharge... so we still don't know if this battery can handle be on high for the duration of a Dyson V8s runtime.
Thanks for pointing that out!
After watching your video I ordered a new one from Amazon for £37.00!!!!
Great! Hope it works well for you!
Thanx for the info, How does the battery pak come apart without destroying it
Hey Mike. It's apparently doable, but I'm not good at it. The cases are pretty mangled by the time I get through with them. The best advice I can give is work slowly on the seam with the smallest screwdrivers you can find. Cheers!
How many mah, I must use?
Hey Selim! I'm not sure I understand your question... are you asking how many mAh the OEM battery is?
Nice video, but can’t find any of these batteries.
Thanks for watching! The recommended DutyOne is currently out of stock (no doubt COVID supply chain issues). Without that one available, I would recommend the runner-up, the TenHutt rb.gy/r38xx7.
Hope that helps!
Hi. Thanks for the review. Wanted to get your input and thoughts on adapter for use with Milwaukee m18 batteries? Thanks
Bought a 5000mah aftermarket battery on ebay and they came broken, the battery just not usable (when charge it, nothing happened, when put them onto the vacuum nothing happened as well) they resend a new one, and i opened up the broken one and nothing seems out of place or burned is anyone has any idea?
Batteries on eBay are notoriously sketchy and I'll probably do a video on them eventually. In the meantime I would stick with the recommendation in this video or the OEM as your safest bets. Thanks!
the link you listed for the amazon battery shows it is unavailable. can u recommend another one ?
Absolutely! The DutyOne has been out of stock for a while... likely due to the current global supply chain issues. While it is unavailable, I would recommend the TenHutt as a second choice. While it doesn't have name brand cells, it is constructed extremely well and performed well in the test... only slightly behind the DutyOne.

Great video, thanks very much.
Thanks for watching, James!
such a great review! ONLY problem is the DutyOne is available NO WHERE. Amazon out of stock and not getting stock so i'm stuck looking at all the other replacement batteries that you didn't recommend. after reading reviews just about all the others have bad reviews after using for a month or more. :( so lost on what to get. Any other recommendation?
Thanks for the question. Yes, the DutyOne has been out of stock for a little while now due to supply chain issues. Another option is the TenHutt from our test. It tested very well and was a solid build. You do give up the name brand cells from the DutyOne, but the TenHutt would certainly be my second choice. Thanks!
My dutyone died a little more than 2 months in with rare use. Pretty sure all these batteries packs are crap shoots.
Not sure why you had to open the "trap door". Otherwise, very good instructions!
The debris door? It just makes it easier to remove the battery without catching on the lip, but not completely necessary. Thanks for watching!
Thanks, great review!!
Happy to help!
amazing review thank you.
I can’t find the Dutyone battery that you recommended in this video. Could you help me out please?
Hi Bryan! It seems the DutyOne I recommended is currently out of stock. Because of this, I would recommend out runner-up, the Tenhutt. It didn't win the competition, but I think it is a solid runner-up for the price.
rb.gy/r38xx7
@@HouseOfVacuums awesome, thank you! Do you know if it lasts longer than the original battery that comes with the vacuum?
@Bryan Young in my testing, the TenHutt beat the OEM battery in terms of runtime. If you are talking about overall life of the battery, it is exactly like OEM where it is the luck of the draw. The best way to protect the battery is to wait 20-30 minutes after using to recharge it. Also, don't let it stay on the charger for days on end. That will help with battery life. Thanks!
Does the v7 with the power head use the same battery?
Unfortunately no. I will have a V7 battery comparison coming out in the next 4 months or so, but I know that doesn't help right now. I would stick with a battery made by Tenhutt or just get the OEM.
it's sold out, can you place links to the other two, thank you
Absolutely! The DutyOne has been out of stock for a while... likely due to the current global supply chain issues. While it is unavailable, I would recommend the TenHutt as a second choice.

DutyOne Replacement Battery, you are advertising here, have pretty bad score on amazon. Have you tested them for longer period ?
I have not tested the DutyOne long term. Looking at the reviews, my guess is going to be that the PCB doesn't handle continuous charging well. Really, that should be avoided in pretty much any lithium battery pack, but some handle it better than others.
My review is really to determine 1) which one lasts the longest, 2) which has the best cells and 3) whether or not the manufacturer is overstating capacity. But like I said in the video, I'm not an electrical engineer who can determine the quality of the PCB, so if reliability is more important that price, the best option is always the OEM battery.
Hope that helps explain where I was coming from. Thanks for watching and commenting. Cheers!
just find the sunpower 21700-3000mah seller said discharge rate is 10C but i didnt find the official datesheet
Your right, and typically I wouldn't recommend Sunpower because of a lack of documentation. But for a 3000mAh 21700, 10C is on the low end of what that form factor is capable of, so I feel pretty confident they are up to the task. Hope that helps!
Great job, thanks.
Thanks for watching!
Great review, thanks for taking the time. Well done sir.
I bought a battery from amazon, the brand was battool. It worked well about 3 times, now will not power. I would be up for sending it to you (my dime of course) to take apart to do your thing. If you would like, comment here and we will figure out how to make that happen
Hey, thank you for the thought and sorry for the delayed reply! I'm sure you have disposed of it by now, but I appreciate the thought! What did you replace it with?
Awesome review!! Thank you
My pleasure!
When doing the battery prices ,just round up the prices insted of saying $19.99 , just say $20.00,Thank you ,grest video :I have just gotten one step closer to being the smartest man on Earth
Glad you liked the video. Thanks for watching!
Thank you!
You're welcome!
Ordered a replacement battery with stated power of 8000mAh vs. the dyson’s 2800mAh and 21.6V.
QUESTION: do I face any issues with such a higher power output?
it's a lie, it's literally not possibly to have 8000mah with lithium cells like this, they just give huge numbers to beat the other Amazon listings
5:23 Wouldn't it be 30 amps? since 10c x 3amp capacity?
Great catch, I miscalculated! The correct formula would be (3.0Ah * 10C = 30 Amp Burst). 10 C does differ a little bit from maximum discharge rating, though. The C rating is the burst rating for a very short period of time, the max discharge is the maximum draw a battery can withstand over the entire discharge... so we still don't know if this battery can handle be on high for the duration of a Dyson V8s runtime.
Thanks for pointing that out!
Are these replacements for dyson battery pack 242151?
I cross reference that number with the available batteries for Dyson models and didn't come up with anything. There are for any Dyson V8 that takes battery part number 967834-08. I hope that helps!
wich one is the more powerfull
All of these will output 21.8V nominal.
I use a Dyson V8 with a Dewalt battery attachment. One 6 amp battery last 3 times as long as the original Dyson battery. If that ever went dead put in another 6 amp battery. I have 6 Dewalt batteries.
I definitely want to test out some of those adaptors. The couple of potential issues I see would be a lower voltage resulting in poorer performance as well as issues with the low voltage cuttoff not being accurate... I just haven't gotten around to it yet. Glad it's working for you!
@@HouseOfVacuums I asked the same thing knowing Dyson is set for 21.6 volts and dewalt is 20v, but I knew dewalt isn’t exactly 20v it’s always a little more. Together with 5 and 6 amp batteries the voltage stays at that rate. Dyson being around only 2 amps the voltage drops to 20 when using it. So I said I have to wait to try it and it worked fine like I thought.
Top Video. Grüße aus Germany 👍
Danke mein Freund!
Can you use a higher amp battery. I can’t get the correct battery
If you are looking at higher amp hour batteries (denoted by Ah) then yes, you can use those. Hope that helps!
@@HouseOfVacuums thank you
My v8 animal battery blinks red and blue when it gets to 3 lights on the charger. What does that mean?
I'm not 100% sure, but it may be that it isn't able to fully get to the 25.2V charge due to a weak cell, which would cause an error. Is the battery still running a decent amount of time or has it become weaker?
I got fed up with thr proprietary Dyson packs and bought an adapter to use my Ryobi batteries. 25 bucks well spent.
What people don’t understand is there’s only a few 18650 cell maker’s… Samsung, LG and Sony. For high drain Sony VTC6’s are the best!!! Off brand batteries are just re-wrapped Samsung, LG and Sony’s. If it’s high drain it’s almost definitely a green wrapped Sony VTC5A or VTC6 or VTC6a. Ohhh they’re using 21700 batteries… better than 18650 for power but not as tested as the 18650 cells, but the Sony 18650 VTC’s can handle 30a continuous load rather well, but when ran in parallel it reduces the amp load on each cell. If you take off the wrap it should have a number batch stamp if they’re Sony’s. If it’s a mechanical switch they probably have a mosfet chip to control temperature. All batteries are rated like D to A+ in grade. All the A+ rated cells go to big OEM companies like Dyson for example… that demand high quality and consistency. You can add more batteries to cut the load on each cell
The big 4 cell manufacturers are Samsung, LG, Murata (formerly Sony) and Panasonic/Sanyo. That being said, there are a fair number of Chinese and Taiwanese companies that make their own cells like EVE, Sunpower, Hunan Prospower, Molicell, etc. They are actual manufacturers and not rewrappers.
I think the rewraps you are referring to are the vaping specific brands like Efest, Vapcell, Imren, etc. They are most definitely rewrapped, lower binned units. The most sketchy of them are rewraps of binned cells from companies like Sunpower and Hunan... the stuff nightmares are made of.
Thanks for watching. Cheers!
DutyOne is now very expensive around $60 -80 vs the other brands $20-40 now.
Thank you for this very informative video. It is very helpful. 👍🏻👍🏻👍🏻5⭐️
Tenhutt still your 2nd choice? Ask because review have some time
To my knowledge, yes. Unfortunately, these battery manufacturers and the version of their batteries change on a frequent basis, so it is possible there is something better out there but I haven't tested it. I'll have a follow-up test of some new models in 3-6 months as an update. Cheers!
I found this video to be very helpful! Thank you for sharing,
Thanks! I'm glad it was helpful.
Very disappointing that a £250 hoover has a battery that lasts little longer than 15 months! Mines still under warranty so Dyson sent a replacement but no doubt I'll be in the same boat in 15 months time. Put me off buying another Dyson
don't keep it plugged into the charger 24/7 it kills the battery since lithium ions degrade when fully charged and kept fully charged.
get a timed outlet or a smart outlet and set it to charge for a couple hours or more depending on usage and then power off.
it does suck that the charging IC doesn't have that built in tho.
but personally no other vacuum holds up to the dyson imo
I hear you. While Dyson is certainly the most ubiquitous cordless vacuum brand, these issues aren't unique to them. It comes with the cordless category in general. While some product segments like power tools have MUCH higher quality battery management, there literally isn't a single cordless vacuum manufacturer that has gone to those lengths to protect the battery cells. Because the bar is so low for consumer electronics, I don't see that changing any time soon. Thanks for watching and commenting!
@@dylan-nguyen i have a v8 and was looking online and it said it was safe to keep them plugged in so it’s better to not keep them plugged in 24-7 I just want it to last and have as much life cause I paid like 400$ for this thing and it’s great.
I'm going on 5 years with mine and it finally started to die on "Low." Rarely use MAX, that probably has something to do with it.
dutyone is currently priced above 70$...missed out
Yikes! That is a huge price hike!
OK, I got really alarmed at first by the temps, then I realised it's probably not Celsius 😂
LOL, now that's funny! I'll make it a point to include that it is Fahrenheit in future videos to spare anyone a heart attack!
Thanks for this video. I just replaced the OEM with the new one a Powtree that I bought from Amazon before I saw your video. The battery I bought says on their product description to use the original dyson charger. When I plugged it in to charge the battery the blue lights do flash even though it appears the charger doesn't insert fully into the port. It's hard to tell by sight because of the plastic housing that surrounds the port. Do the blue lights flashing mean that the battery is getting fully charged? Should I be concerned about the charger not appearing/feeling like it is fully inserted? Or should I buy a different charger for the replacement battery? Thanks for your help.
With barrel port chargers, it can sometimes appear that they are not all the way in when they actually are. As long as the light is flashing blue it is getting voltage and charging. Depending on how they circuit board is controlled it will either turn off that light or shine constant blue once completely charged. But I don't see a reason why you would need a new charger since there is voltage getting to the battery. I hope that helps!
@@HouseOfVacuums Yes Thanks so much!
As of 9/15/22 the price has shot up to $70.25!!!! YIKES
Whew, that's getting pretty close to the OEM!
A lot of talks and finally no comparison Genuine vs Aftermarket.
I like to do "a lot of talks". You must be fun at parties :-P.
@@HouseOfVacuums
Yes, but no comparison as described, you compare aftermarket vs aftermarket, where is Dyson battery?
Interesting video thanks. Sadly the Dutyone battery user reviews on Amazon are terrible and almost all packed in in a very short time.
Definitely, if you want the best for safety and consistency, genuine Dyson is the way to go!
I'm worried about a fire with non oem. Otherwise id be all for it
Agreed, it is always a risk. For safety, you can't beat OEM.
WARNING: do not waste your time watching this video because none of the batteries reviewed are for sale anymore.
The best option is to not buy any of these batteries. Instead buy a battery adapter for the any of the Milwaukee, dewalt etc batteries. I can run my v8 animal on normal with a Milwaukee 5ah for about 40 minutes and about 12 mins on turbo.
The dewalt batteries don't have a built in temp cutoff which as you saw in the comparison is what is saving the batteries from burning up. Also If you use the adapter you shouldn't drain the battery completely so that it doesn't get damaged. Lastly, they may discharge more quickly when left connected. This happened to my old dewalt 18v(nicad) drill with official dewalt adapter for use with lithium batteries. I can't say the same for milwaukee batteries though.
just convert it to milwaukee batteries or dewault.
Dyson hasn’t had a v8 battery in stock for like a year, so 3rd party is basically your only choice
Yes, with supply chains still being a mess I think they are diverting all their new batteries to building new machines. It's unfortunate the genuine batteries are so hard to come by.
2 bad batteries have gone bad in the same amount of years. Yea aren’t worth a battery pack a year. $73 for dutyone now
Hope the DutyOne is still going strong for you!
Even if the batteries inside had the brand and model number, it means nothing as most batteries are fake from china, some the capacity maybe correct but doesn’t mean the brand is genuine and the rest of the spec is accurate, I bought many cells that claim to be Panasonic or Sony or LG but most are fake, some have real capacity but are not genuine still, so even if the brand and model number is on the cells, it means nothing.
Best to build your own battery with cells
True for name brands, but there isn't any reason to fake already Chinese cells like BAK, EVE, Sunpower, etc. These video aren't to prove that one is awesome, it is more to show that most are pretty terrible.
@@HouseOfVacuums yh I understand that part, I was just telling you my experience as I buy lots of cells, obviously china only fake the decent brands and no reason to clone a china cheap brand, I just have tested batteries from 10 different suppliers and near enough everyone was either fake capacity and or fake brand like LG, Panasonic or Sony etc
If you have tool batteries just buy an adapter
Video upcoming about those!
The best dyson battery is to just buy an adaptor to any non-dyson battery.
Yay artificial scarcity! Sounds about right for a "premium" brand...
Dyson has been known to make parts scarce... but in this case I really think it was the supply chain issues the last 2 years. The chips used to control the batteries were impossible to find for a while, so it unfortunately wasn't just a Dyson problem. That being said, I also distrust Dyson's part availability in general. Cheers!
Fair, but you'd think with the YUUUGE margins Dyson has with the price of their packs, they'd have a bit more leeway to bump up the offer prices to their suppliers so'd they'd be near the front if the line...
you're better off rebuilding an oem with better cells
You can... it just takes some special steps. The PCB will lock up forever if you remove all voltage from it, so you need to be able to provide 12-24 volts-ish in parallel with the existing cells prior to removing them. Then you need to attach them, which is best accomplished with a high amperage battery cell spot welder. You can solder it, but that prolonged heat can damage a new cell... end you right back where you started.
Thanks for watching and commenting!
@@HouseOfVacuums In my experience this is not entirely true. I have recently rebuilt two different (ZH2, VE6) V8 batteries with new cells. Having the rumoured need for a parallel voltage supply in the back of my had I tested the OEM-Pack by disconnecting and reconnecting the nickel strips first. The pack worked just fine after that. Note that the battery does not put out any meaningful voltage outside the vacuum regardless of pushing the little switch. To test the functionality (of your partially disassembled battery pack) you actually have to slide it into the vacuum (mind polarity!). If the battery works, the vacuum will turn on (without pushing the micro-switch).
I have also found that it is possible to loose functionality if you disconnect (and reconnect) one or more of the middle voltage sensing strips. I could regain functionality be disconnecting and reconnecting the main positive afterwards. This apparently resets the battery management system on the PCB.
When rebuilding my two packs both PCBs would sit on the bench without any cells for days. Reconnecting the cells I started with the main negative and connected the strips in ascending order finishing with the main positive.
Please note that this job is far out of scope for layman. I would not recommend it due to electrical and fire hazards involved and the need for a spot welder. It is even extraordinary difficult to open the packs without damaging the plastic cover.
Very interesting, thanks for the information and the detailed explanation. It is good to know that it can be rebuilt without the need for parallel voltage if the need arrises. One of these days I'm going to "hot rod" one of these batteries with higher capacity cells, so this is great to know. Cheers!
most of these batteries dies in few months. So you pay $40 or so for 3 to 4 sucky months, that is the truth of Amazon batteries for Dyson.
There are many that don't work very long, whether it is cheap cells, a cheap BMS or both. Hopefully these videos help narrow down the ones that have the best chance of lasting longer than a few months. Thanks for watching!
Amazon reviews disagree
That's why I take them apart; Amazon reviews are notoriously unreliable. There are certainly negative experiences with replacement battery packs, so if you are ever uneasy about their safety, it is always better to get the OEM battery pack like I stated in the video. Hope that helps!
when the battery dies just chuck the lot in the bin and get a real vacuum cleaner that runs off the mains
Mains power is my preference as well. But when you pay $4-500 for a V8, you may want to lengthen the life with a new battery. Thanks for watching!
Why do you think these have literally doubled in price in less than 2 years and EVERY one of THOSE big vacuum makers have made an inferior copycat one of THESE! You can go wrestle with that Kirby if you want but I’ll pass because this has proven to actually clean better.
Sadly these reviews don't last for long... the brands change like the winds and disappear after the companies run out of supplies for their manufacturing runs
Part of my selection process is to look for "brands" that have a history of sales on Amazon. For instance, TenHutt, FirstPower and DutyOne have all been around a while. Unfortunately, the DutyOne seems to have run into supply chain issues... so we'll see what happens there. Thanks for the comment!
People enjoy paying low prices and yet bash fake knockoffs, rofl! hypocrite at its best, you encourage fake goods. Dont complaint ever again.
Hmmm, never stated that they were Dyson units... they are replacements which is common in many industries. Do you think the mechanic that uses Fram oil filters on your car instead of Honda, Toyota, etc. is encouraging fake goods and a hypocrite? Seems like you are a little worked up over a vacuum battery video there, bro.
I bought a homesuit 4600mah battery. We're used. 5 month, but i think max. 10 work hours. Yesterday didn't work more. One of the 6 battery is failed. I replaced to a 2000mah this one, and alive again. I haven't capacity tester, but i have the battery type code:
PROS18650 F2 3.6V
23E182Y10
I didn't found any information, about this battery, but if you find it, you have information about another one company (and pls write me also).
Thanks!
Thank you so much! Your generosity is greatly appreciated!
