Our Dyson replacement battery video series are our most popular and most expensive videos to produce. For every video, we have to buy the vacuum and batteries at full retail. If you found this video helpful and would like to support our work, please consider giving us a Super Thanks above. We appreciate you watching!
I wish I'd seen your video before I purchased, but I bought from Amazon the Battool 6000mah that was on sale for $55. It came with a free replacement filter. I've done analysis and just went with Amazon feedback. My oem battery lasted about 2 years. This unit I swapped in seems to be far better than the Dyson unit for me. Plus "free" filter! I'm super happy with it. When it comes time to swap for our other V10, I'll check your channel!
Hello, first of all, thanks for your review and very useful information. Tenhutt V3 3.0Ah is no longer available on the link you have provided. Could you please send another one if possible? Thanks in advance.
With the battery industry getting bigger, i would like to see another video update next year for newer brands and larger capacity batteries. Thanks great video
I will certainly update these videos along the way with new offerings. Still wishing there was a reputable brand that made consistent replacement batteries for Dyson, but unfortunately I haven't found one yet. Cheers!
@@HouseOfVacuums im waiting for a battery with 26650 model instead of 18650. Also why are there no videos on UA-cam for roomba replacement batteries. Seems very unpopular i guess
First Thank you for that considerable information more than i expected but very welcomed i will go with the tenhutt battery so i can afford two i never go to the dealer especially car dealers where i paid over 300.00 for a replacement fob at least they were able to update our backup fob on a nissan rogue... true story Sorry!!
Good question! Home Depot, Best Buy and Batteries Plus should all take old lithium cells for recycling. There is usually a drop box by the customer service desk at Home Depot, so I usually take them there.
Hi Matt, great analysis. however as other users commented, the Tenhutt is no longer available at amazon. any advice of a current battery available at amazon for my v10? I dont find any DutyOne or FirstPower. thanks in advance
Hello how are you, I am writing to you from Spain. thanks for your video. I need to replace the battery of my dyson v10, can you confirm that this model is still the best?
To my knowledge that is still best unit I have tested. There are always new models coming on the market and Chinese companies like to change brand names on a frequent basis, so in another 6-9 months I'll likely do another test. Hope that helps. Thanks for watching and commenting!
@@HouseOfVacuums If you have any videos on taking the battery packs apart, that would be great! If you don't, then consider it as ideas for more videos. When I have more time, I'm going to take apart the old pack and see if checking individual cells will show anything.
@@HouseOfVacuums , Mine finally went out. It lasted 1.5yrs. However, they seem much easier to work with as opposed to the OEM battery, which is overbuilt and over-engineered. I took both apart to see which is worth replacing the cells. The OEM seems like too much of a hassle. So, ordered 7 Molicel 21700 P45B 4500mAh 45A. It ran me up to $55. However, I think it will outperform even the OEM battery I have once I replace the cheap batteries with a name brand, which has a higher capacity and a continuous current well above the OEM's.
Liked and subscribed. Greetings. Your Tenhutt link now shows a '4 amp' (claimed) but the reviews are spotty. Any chance you can see if it is still the same quality 21700 cells or did they go cheap over time? Thanks again for these tests.
I will have a new V10 battery video coming out, likely over mid-summer. However, I can say that generally Tenhutt has been pretty decent at picking good cells. The spotty reviews are really probably more due to bad batteries stemming from charging issues. The best way to avoid that is to wait 30 minutes after using the vacuum to charge it. Then only leave the vacuum charging until it is full, then unplug it. This will help protect it and give it the best chance of working over the long term.
After your video I was quite surprised, that on dismantling my Dyson V10 stock battery I found 7 Molicell INR18650-P26A. So it seems they do not even put something else themselves anymore. After digging a bit into these nonsense chinese batteries I decided to just buy some Molicell P28A off NKON and exchange the cells on the stock battery myself. They come with a small 200mAh capacity adder and same 35A discharge current, as compared to the P26A. Disclaimer for the kids: Don't try this at home ;-) Nice video though!
I have the tenhutt and the OEM battery. The Tenhutt looks way simpler to take apart and to work with. The OEM seems way too complicated and over-packaged. Yes, I spent about 50 on the tenhutt. Now I'm spending another 55, to replace the batteries that lasted about 1.5yrs (still cheaper than replacing with an OEM battery). I'm replacing the cells of the tenhutt with Molicel 21700 P45B 4500mAh 45A. This will, surely, be a decent upgrade... even to the OEM batteries. Let alone the fact that 45A is well above the continuous current of the P28A, which is 35A. PS. i also ordered the P28A for Worx batteries that I need to replace.
You are correct, I disassembled one of the first gen V10 batteries. They have since been switched to 21700s, but good eye on that first V10 video of mine!
Didn't even have to watch the video to know Chinese battery packs use the grade B cells that were made for vapes and rechargeable flashlights. Thanks for confirming though. I think ill pay the higher price of a Dyson battery pack.
Wish your review had come out a week earlier and I would have purchased the Tenhutt. However, after looking at a bunch of options, I went with the OEM battery which I just installed. I bought an aftermarket battery for my previous Dyson and it lasted about a day past the 1 year warranty.
Question - is it possible to make an external battery pack with a much larger capacity - say true 10,000 mah and just run a wire to the Dyson head? That would do three things: Greatly increase battery run time, increase battery life as it is running on lower percentage of max discharge capacity, and reduced the weight of the vacuum unit itself. If no, what's the rason it cannot be done? Thanks.
Sure, technically it could absolutely work. I guess my question is, where would you put the pack? I'd be hesitant to home-brew a battery pack and then strap it to myself with a backpack or something similar... just my own personal preference. Let me know if you try it!
There are battery converters for power tool batteries to use instead of the original dyson batteries or after market ones. I haven’t found one for the dyson v10 yet but I’ve ordered one for the dyson v8!
Great video thank you so much. One question though, I've seen a lot of the older model Dysons have aftermarket battery adapters that allow you to run power tool batteries like DeWalt and Milwaukee. I haven't found an adapter for the v11 though. Do you know if they are available for the v11?
They aren't, unfortunately. The 18V batteries are already downvolting the motors on the V6-V8. Anything from the V10 on uses 25+ volts and won't run on the tool batteries. The PCB just thinks it is a dead battery. Hope that helps!
Great video. I have a V8 and watched that vid and this V10 vid too, and it seems the 21700 cell is an important determining factor in deciding which battery to buy. So, how can I know whether the replacement battery has the 21700 without tearing the thing apart?
It is touch to know about the 21700 without tearing them apart. You could try contacting the sellers and asking which form factor it uses. Many of them will be willing to respond. Could they lie? Yes. But it is certainly better than nothing.
Hi Matt , Thanks for this very useful video! But the only first great problem with all these (too) powerful cleaners is that only one range of cells for so many output/amps is not enough . Specially if used with max power, which kills quickly the good cells...and very quickly the chinese cells. All discharge amps are at the limit , and Lithium hates strong discharges, even with good cells if often used and first of all during a long time. Changing 18650 for 21700 is a poor solution. The best would be to propose also batteries with minimum 2 ranges of cells in // : much longer worktime and first of all much longer lifetime.( like for power drills batteries)...but commercially totally uninteresting...James Dyson is a clever man .
I agree that having two series banks of cells run in parallel would be the best solution. I have serious doubts about whether or not any vac manufacture will ever be bothered to do that since they are notoriously cheap. But one can dream!
@@HouseOfVacuums If you consider the full discharge of the battery ..in 5, maxi 10mn with max power, it's a real pain for the cells, even for very good cells , even more so if you try this with an already half-discharged pack. So it's not a dream , it's technically an obligation , ...but commercially an aberration.
Question -- Why do the Dyson OEM batteries fail so quickly? I'm told never to keep the vacum plugged in --- so don't keep it in the charging wall unit hanger. right?
Honestly, it is hard to say what the variable is. Some folks leave them on the charger and that causes the BMS controller to fail. They also fall pretty often since they can't be locked upright, and that could damage the cathode, anode, separator or tab of a cell. Also there are 6 or 7 individual battery cells in each pack, which gives you 6 or 7 times more opportunity for a cell failure. I will say this. Vacuum companies in general don't take battery management systems or robust construction seriously. I have 8 Milwaukee power tool batteries that are going on 7 years old now without a hitch. Industries like power tools have proven that you can build a robust consumer battery pack, but that costs money. And vacuum companies are notorious for cutting corners for either profit or price advantage. It's unfortunate, but consumers will continue to buy Dysons over and over again with batteries that fail. Tradespeople are less forgiving when they rely on a tool to make a living. I'm rambling, but there are a LOT of reasons battery powered vacuums less reliable. Thanks for the comment!
Possible ...if the charger itself is unplugged for any reason. Normally if you let a battery connected to a charger which is not itself connected to main current , you have an upside down operation : the charger will slowly discharge the battery for its own use. If too low voltage, the BMS stops the discharge...and voltage goes a little higher again. Well, the BMS allows a new discharge and stops again with too low voltage...and so one...But at the end if the voltage falls with too empty batterie (a BMS is not perfect and a very low milliamps discharge control is difficult) , then the Dyson BMS "locks" definitively with red light. So never let any device connected to an unplugged charger during a long time . Voltage discharge is very low, but permanent....like in your car with only a little lamp switched on : if the car is not used , after some days the battery (although with 70Ah) is empty. You can test it easily with a Drill battery : Charge it full and test the voltage. Then let it connected to the unplugged charger and re-test the voltage after simply a week : voltage is much lower. For Dyson devices , the best is : not install the jack in the rack , and charge separately . So you disconnect the charger from the device every time after full charge.
ur wrong sadly, the V10 doesn not have ANY BMS controller. SO yes the original Battery dies permanantly when any cell go in inballanced@@HouseOfVacuums
Currently the link on Amazon for Tenhutt takes you to a 4Ah battery and they have a 5Ah battery as well for this model. Any thoughts on these as the 3.0 is no longer available?
I personally haven't cut up the 5.0Ah battery, so I couldn't venture a guess as to what is in there. I will say, the two TenHutt batteries I have open have both used decent cells. That being said, almost all of these batteries have incorrect Ah ratings, so you may not see much real-world difference between the two.
They can and I am evaluating an adapter right now for a video. There are some trade offs, but it is a viable option for those already in a power tool battery ecosystem.
@@HouseOfVacuums that is exactly what I’m in the market for I am a plumber and have a dozen m18 batteries and would love to swamp batteries and keep vacuuming then have to stop and charge the whole unit
The problem with Chinese batteries is that they may work well for the first few months but they will lose any functionality after that forcing you to buy another one. Very wasteful. I think I will just bite the bullet and buy an OEM pack considering I am still on the original 2.5 years into owning one and can probably get another 6 months out of it.

Tenhutt out of stock 4/2023😢
Wish I could find another hood replacement. Might have to go oem.
Bummer! Tenhutt has been a little spotty recently. I would probably go FirstPower if you can find one. I hope that helps!
Great video Matt. John in Ohio
Thanks, John!
Great video. Thanks.

Definitely weak cells. It's time to replace the battery. Hope that helps!
