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!
Hey just to let you know you're affiliate link is pointed at a seller no longer stocking these.
I don't want you to miss out on revenue as this was such an informative video you deserved the sales /
Thanks for the production quality, clarity, honesty, accuracy, technical depth and every other metric for what youtube reviewers and content creators should be striving for, you hit it out of the park my man.
Thank you so much for the kind words. That means a lot!
You are definitely a nerdy science geek and I appreciate you so much because my talents are limited to the use of the internet and a screw driver to remove and replace the battery. you saved me from what would otherwise be junking my current Dyson and needing to buy a new one.
Very helpful. I appreciate your approach to testing. Well done!
Thank you! Glad it was helpful.
Stellar work, thank you for your time doing so.
Happy to help!
and you are not an Electrical Engineer? Your knowledge and description are TOP NOTCH. Thank you so much for this comparison. I purchased my new battery based on your video alone!
Thanks Christian, I appreciate the kind words. Maybe in another life I would have been an electrical engineer... hahaha. Cheers!
This was so helpful! You’re a wizard 🧙♀️
Happy to help out! Thanks for watching and commenting.
Wow. I am impressed by your testing process & standards. THANK YOU for your diligence, Sir!
I have just started down the path of getting my V6 working. I found it nonfunctional 2 days ago.
No power, lights or anything. The V6 charger output measured to it's 26.1V spec.
As far as battery choice goes, the First Power brand looks like a good choice for me.
THANKS! Your video has given me quality information to use in making my battery choice.
Thanks for watching, I'm glad that I was able to help with your decision. Best of luck!
Great Job on the Review Break down!
Glad you liked it!
Nice detailed breakdown.
Thanks for watching and the compliment!
Thank you for this review, very very useful
My pleasure!
Well made, amazing review... 👏
Thank you, I appreciate the kind words!
Thx. Awesome video. Great analysis!
My pleasure!
Thank you for this very good video! I wish I had watched this before I did my 1st (unsat) battery change. 😎😎
So glad it helped!
That’s a brilliant video thankyou very helpfull
Thank you for the kind words!
Great presentation!
Thank you Patty!
Great video, the level of detail i wanted to see. I wish there was someone selling an empty replaceable cell battery so i can simply put my own cells inside
That would be a super cool concept. I would imagine the liability could be the limiting factor, but who knows?
Thanks for watching and commenting!
No. It didn't show how to remove the battery pack.
Hi Matt, One of your best battery videos.
Well presented with a lot of preparation done in advance and well thought out presentation.
Excellent. What more can be said.
John in Ohio
Awesome, glad you enjoyed it!
Just a quick note here, the Taiwanese Molicel factory in Canada was shot down years ago. At least the one I live close to.
Great review by the way as I'm due for a new battery pack for my Dyson as well.
Thanks for watching and the comment! Molicel did have a location in Canada that was shut down, but they do still have a a location in Maple Hill, British Columbia. Thanks again for watching!
Hi, based upon your teardown of the genuine item, what would you say to repacking the original unit with fresh, quality cells? I'm an electrical engineer, and know one side of a soldering iron from another - but I've never attempted to crack open a Dyson battery pack. For a start, does the plastic case come apart easily without needing to destroy it? My Dyson run-time is significantly degraded, but I'm not ready to risk destroying it yet ....
Very helpful information thank you so much, please update the product link to the battery vender.
Thanks for the heads up! This has been updated.
This just shows that a well build cell, kept within spec (BMS) will last a very long time :) 8 year old VTC4 from a high drain application, and still at around 1.5ah only down from 2.1ah :)
Well, I'll be honest, on this particular vacuum I think it was luck of the draw. I have not treated this battery well... constantly on the charger, starting charging immediately after using, etc. So in this case I think I got really lucky... it is certainly one of the longest lasting Dyson batteries I have come across.
But to your point, VTC4s are pretty fantastic cells. If any cell is up to this duty, it would be these.
Thanks for watching and commenting!
Not when they program the bms to disable the battery after like 100 charges or so.
My battery went bad and I tried to order a “good” one from Dyson. But, they were out of stock and no idea when they would be able to provide. So, I replaced the Dyson fixed battery with a Makita removable LiOn battery system. It’s a little bulkier than the original, but I can now swap out batteries, and even use a much larger 5 Ah battery for longer run time. Not something easy to do, but really don’t understand why Dyson doesn’t go that route.
Thanks for watching and commenting!
I asked why they didn't do that for years. They have finally updated the whole V11 line to have toolless battery swapping... but, man, it took them long enough!
Thanks
Happy to help. Thank you for the Super Thanks!
House, thanks for all the work you put into the testing and production of the video. One point of clarification, though: You decided that the First Power battery was the "winner" at 16:06, but then at 16:29, you say, "All that being said, the best option is always the OEM Dyson battery." Can you clarify how these two statements jibe? If FP is the winner, then why is the Dyson one "always the best option"? Thanks.
Thanks for the comment!
My statement was made within the context of the Amazon sources batteries. Out of the 4 I tested, FirstPower was the best. However, replacement batteries still carry inherent risks and reliability issues. So, ultimately, the OEM is the gold standard and FIrstPower rated first among 3rd party batteries.
I hope that helps, please let me know if you have any other questions or concerns!
@@HouseOfVacuums Okay, thanks.
Thank you for making this video. Alas First Power doesn't seem to be available on Amazon anymore. Not the best solution, but I'll be gauging the user reviews by checking the 1, 2 and 3 star reviews of those with most number of reviews (here in Australia).
Happy to help. I'll have an update video coming soon, so hopefully next time they won't be out of stock. Cheers!
@@HouseOfVacuums I ended up ordering one that Amazon advertised as “#1 Best Seller”, even though it had fewer reviews than a similar one. Probably won’t know how well it lasts till we’ve had it for 3 to 6 months. My original battery lasted years, when it was the last of the DC59 before rebranded as V6. Amazon battery was $30 vs Dyson’s $120 in Australian dollars.
Very good video, do you know if all lithium batteries are the same?. Do you know if I can create a battery with Tesla batteries for a vacum cleaner?
Regrads,
Luis
Thanks for commenting, Luis! Not all lithium batteries are the same. Every model from each manufacturer has different specifications that make them well suited to certain applications. For a Dyson V6 battery, you must use cells with a minimum 20 amp discharge rating. Check out our battery dissection playlist as starting point.
I'm unfamiliar with the different Tesla cell specs, but any cell with that discharge rating would work. I don't think that a Tesla cell would necessarily be better or worse in this application. Particularly for the price, I would still with a quality cell from Sony, Panasonic, Samsung or LG.
Just FYI, I bought the First Power battery on Amazon based off this video in Jan 2022. Yesterday it exploded and sent fireballs all over my pantry while it was just plugged into the charger.
So sorry to hear that, Troy! I'm glad you are safe. While replacements are cheaper, the OEM batteries are always the safe bet because of quality control and components. It is certainly is a risk/reward analysis when choosing replacement versus OEM.
How long was it on the charger?
This review was great. Fact is that there are no batteries past 3.5 Ah and the 3.5 Ah batteries are very expensive. 100% of aftermarket batteries for the V6 lie about their capacity ratings and as you said, can change their cells at anytime.
I did purchase 2 different aftermarket batteries on Amazon with the sole purpose of removing and spot welding in newer higher capacity, high current cells. I had to return the first one due to it getting stuck on and not responding to the power switch. I didn't check if they use a NC or NO switch but the button is toggled on when the motor is off and toggled off when the motor is on. I then disassembled it and did a non-destructive capacity test using a hobby charger. As expected, they both came in well under their ratings. I left detailed reviews on both of the batteries and was surprised that they still accepted the return after I left a review showing it apart.
I have already purchased a few grade B LG 18650 INR rebranded cells and swap out the bad cells. I suspect that the BMS on my original Dyson battery has gone bad.
Yeah, when the cells are quality and the pack fails to charge it is usually the battery pack's PCB that is gone. That's why I have never gone down the road of trying to rebuild Dyson packs because often it is the PCB and if it isn't then I don't know how long after it will last. It certainly seems like an area that Dyson has overlooked, because you don't run into this many issues in other industries like cordless power tools which have very reliable BMS systems now.
Thanks for watching!
Keep missing which you said was best and youtube has so many ads I don't want to rewind anymore. So which one is best?
The winner of this comparison was the FirstPower, the link is in the description. Cheers!
Using a $18 adapter, we now use a Milwaukee tool battery! Nuclear.
Video upcoming RE battery adapters. Be on the lookout!
I've just busted open an original Dyson v6 pack, lost the spring lol. Just wanted to say the wires to the switch and the charge port seem very thin gauge to me on the Dyson original. I suppose it's probably okay because the microswitch is just a signal switch, it's just looking for continuity or not (actual vacuum motor current runs through the beefy prongs). And the charge port, although 26V, is a fairly small current, I think I saw 700mA or thereabouts.
You are absolutely right, it is just a signal switch. It certainly wouldn't be a deciding factor for me, but I thought it was worth pointing out since it appears that cost was the manufacturer's primary concern.
Thanks for watching and comment!
@@HouseOfVacuums Charging is also done at very low input levels (typically things like 1/5th of the output level). They start by charging at constant current then switch to constant voltage for ebike batteries and tools so probably do for these too.
Interestingly, i've just stripped down an original V8 battery and it contained Molicell cells. These are not 18650's as they are slightly longer (70.2mm) and a larger diameter (20.4mm). They are branded with Dyson's logo and numbered 1NR-20700A / 0842K10603. These do not fit in most fixed 18650 chargers but will work in those with adjustable earth electrodes. Now i just have to find something i can use them in...
That is very interesting, I've never come across a genuine Dyson battery using Molicell cells. But they are great, so I would have any hesitancy they can meet OEM spec.
Many more recent Dyson models have moved away from the 18650 form factor to the slightly larger 20700 or 21700 cells. They provide more capacity and typically higher discharge rates than 18650 cells. The 20700 standard was created by Panasonic/Sanyo to add capacity to cordless tools and the 21700 standard was pushed by Samsung and LG Chem for high discharge applications. The 21700 form factor can also be found in the Tesla Model 3 and some models of their Powerwall.
@@HouseOfVacuums That's them exactly. After doing some checks the Molicells in the Dyson battery are indeed classed as 20700 cells. I didn't even know such things existed...
@@lesrogers7310 Just so you know 18650 means 18mm wide and 65mm tall though the height and thickness can slightly vary due to wrapping and protection circuitry built into the tops. this is why the 20700 cells measure close to 20mm and 70mm. Just the slight increase of the size can increase the capacity quite a bit, reason why tesla started developing their own 2170/21700 cells.
I really want to buy the Milwaukee M18 adapter for this vacuum.
I'm hoping to test those eventually. My two concerns are the voltage difference (the machine will run at a lower speed) and the low voltage cutoff. I would definitely want an answer on those two points before I recommended them.
Can you do another video on this? none of these brands are available anymore
Planning on doing one around May or June, so stay tuned!
Sweet!
Hope you enjoy it, this video took a lot of time.
Thanks for watching!
Thank you so much - also would love to know of any replacement battery packs outside of China. I just spent 2 hours looking at most 4+ star replacement packs and they are all from China or unlisted (even on their website). :( Would love to support an American company or an honest country of origin
Unfortunately, not to my knowledge. I do think there is a huge untapped market for a quality replacement battery that falls between OEM and the Chinese "cheapies". Something similar to Wasabi or Watson with cameras. Perhaps one day! Thanks for watching!
Hi, I just received a Dyson V6 Absolute from a friend and it needs a new battery. The First Power replacement battery model you recommended is no longer available on Amazon. I'm not great when it comes to this stuff and am working on a tight budget. Can you let me know which is the next best option? Thank you so much!
Unfortunately, due to the age of this video I don't have any current information. However, my experience with DutyOne and Tenhutt batteries has been relatively positive. Hope that helps!
Electronics engineer here to help... Have you noticed how the Dyson runs at the same performance from start to finish of a charged battery? That it simply doesn't change speed as the battery runs out? That's because somewhere in the system is voltage regulation, and the most efficient voltage regulators keep the same continuous power output from the battery. This is important as the Dyson may have (I don't know) a lower internal working voltage. With the voltage regulation (using a buck / boost controller) it could inflate the mAh times for a specific battery. High voltage, low current at the start and as the battery voltage drops as it drains it would increase the current, keeping the power constant. That would explain why some are doing better than others, one that are able to sustain a higher voltage from a fresh charge for longer. However, that's not going to explain the wild differences from something that should run twice as long as the Dyson battery but doesn't!
Next, the switch's thin wires. Simply not important. That switch isn't carrying any significant level of current, might not even be a mA. For the recharging, same, the current is much lower because the charge time is far longer than the run times. Thin wires aren't so important.
Finally, the blacked out markings. It's not uncommon for Chinese companies to buff off the names of ICs etc to stop people copying them. I suspect in this case they know they've got a good battery and are trying to make it more difficult for someone to see which one they're using. I wouldn't say it's ideal, but probably not blacked out for the reasons you've stated.
Hi John! Thanks for the insight, that's super appreciated. I do agree these off-brand battery manufacturers are not sophisticated enough to actually be calculating the mAh based on voltage/current demand. While they are certainly pulling the wool over people's eyes by overinflating the ratings, it's certainly an interesting discussion!
Good to know about the blacked out markings as well, because I've run into that a few times.
Look forward to chatting with you on future battery videos. Cheers!
I'm thinking of converting one of these packs to 26650 cells, 2 cells on top of 4. They have much better specs, than the 18650. it wouldn't fit in the cradle anymore but I think the charge plug can be removed from the cradle to plug straight into the pack. Do you have Any thoughts on the matter?
I think it is doable as long as you keep the same number of cells so the voltage remains the same. The major issue I would foresee is how to encase them in a housing for safety since you don't want open battery connection for safety's sake.
Your best bet would be to run 18650 cells in a 6S2P format. If you had access to a 3D printer, you could easily design a case that could accommodate this and connect to the portion of your case that screws in and plugs into your vacuum.
I have often thought of that... then I realize I don't know any kind of CAD software and immediately dismiss it 😀.
Hi there
I got dyson v8
Battery dead after 4 years.
Any links for the best replacement battery i can buy?
Thanks for the comment! My most recent video actually addresses this very question...
th-cam.com/video/bDDigo6hCaw/w-d-xo.html
Is there any link between 1 battery and their capacity of mAh?
In these particular design the batteries are organized in essentially a straight line, positive to negative end and so on. This is called a series configuration. What this does is increases the voltage of the battery, but it does not increase capacity or amp ratings. So if you have a series battery pack and you know that one cell is 2000mAh, then you can also ascertain that the entire pack is rated at 2000mAh.
I hope that helps!
Thank you again House of vacuums I ordered my battery through the link provided easy to install about 5 minutes after a full overnight charge I did a real-life vacuum test meaning that I actually vacuumed my whole house the new battery lasted 18.5 minutes on low ( almost enough to vacuum my house two times ) within one minute of the vacuum battery being depleted I took a temperature with a laser temperature probe 101° ( dead center back of battery ) The very next day on full charge I ran vac on high it lasted six minutes and 48 seconds and the temperature on the battery was 120°. Description on the bottom of battery - Li-ion rechargeable battery pack for dc62 / dc61, 21.6 v 5000mah, 108wh , Some warning information and lastly made-in-china.
Question since the batteries was a little warm is it okay to charge it up or should it be cooled down before charge ?
I know in the past five years with the V6 I never let the battery cool down before charge.
Thank you
Sounds like the temperature is staying within reason... although that second run was significantly hotter. Did you have it on high for that run (that will indeed cause it to heat up)?
For charging, it is best to let the battery completely cool down before charging... I usually wait about 30 minutes. When it is warm and has just been run, the electrons are still "excited" and charging it in this state can stress the battery.
Thanks for watching and the comment!
@@HouseOfVacuums Second run from start to finish 100% on high speed.
To answer your question.
All batteries when they get warm is when they are most vulnerable for permanent damage. When charging cycle is finished, the cells are usually warm. You should let them cool down before usage. This also applies under heavy usage to depletion, cells will get warm and they should cool down prior to starting the charging cycle.
What’s the best ?Looking for one that doesn’t burn my house down.Watching vid now .lol
If I was going to go with a non-OEM battery, I would choose the Power Extra based on the cells. On the topic of the Amazon reviews, the one nice thing about the Power Extra is that Fakespot gives it an "A" rating for review reliability, meaning there are a high percentage of real reviews. Other items may have higher star ratings, but if they score "B" and below on Fakespot they are likely purchased reviews or fakes.
As to not wanting to burn down your house, I'm not an electrical engineer so I cannot vouch for the PCB. However, the cells are reliable. If you want the safest, the OEM battery is the way to go even though it is expensive.
Cheers!
I ordered the First Power 4.0ah back at the end of July. So far I'm impressed with its performance.
I initially charged it fully and we've used it a hand full of times without recharging.
I've read that they recommend to initially conduct a full charge and then use it until it fully depletes and then fully charge it again. This helps the memory capacity on the cells. Obviously and mostly important is to charge it once it cools down from using and also use it only when it has cooled down from charging. This supposedly prolongs the life of the cells. I'll try to give another long yerm update.
Thanks for the feedback, I would love to hear a follow-up! I truly think that the two worst things owners do with batteries is 1) charge them directly after use and 2) leave them on the charger. I've got 8 stick vacs now that I use for testing and only replaced one battery, but I've avoided both of those pitfalls.
Hope the First Power keeps up the good work!
@@HouseOfVacuums I sure will. Thx again
Hello HoV. I have been looking at a First Power 5.0Ah battery for my V6 on Amazon.
The item description says to wait 15-30 minutes after use before charging, otherwise battery life will suffer. Do you know what this is about? Is this about heat?
My V6 has a charging base and that is where I keep it when I am not using it. So it it always plugged in.
Should I put the charger on a switch and hope I can remember to turn it on after 30 minutes?
Once the battery is charged, should I switch the charger off?
THANKS in advance for any insight you can provide! 👍👌👍 👁
Great question! When a battery cell is done discharging at a high rate there is still a lot of movement/heat built up in the electrolyte in the cell. Giving it some time to cool down to a resting state prior to charging helps the cells last longer.
@@HouseOfVacuums You could put the charger on a cheap mechanical timer to charge in the middle of the night.
I feel like the only way to really get a good battery is get a generic pack, and swap out the garbage cells with some extremely good cells, particularly since Dyson has none in stock... but will the control board still wreck them or actually balance them properly?
Thanks for the comment. Dyson batteries use very high quality cells, so the issue isn't so much an issue of cell issues but, typically, either stress or continuous charging. For stress, there are a few things that shorten cell life like running on high constantly (high drain situation) or charging the battery immediately after use without a "cool down" period. Both of those are hard on cells. Then there is constant charging which can also damage the pack. Essentially, the PCB is constantly monitoring the voltage in the cells and providing small top offs if necessary. Doing this 24/7 is hard on both the PCB and the cells. The best option would be to unplug the vacuum once charged. th-cam.com/video/XhcWERhvRYY/w-d-xo.html
I’d give a 1000 likes if I could, thank you for you doing a vid like this.
Thank you for the kind words!
@@HouseOfVacuums unfortunately as you predicted the best one rated may be buying cells in bulk - appears to be true. More recent reviews had pics of low quality cells and poor performance. So it’s a gamble on Amazon all full of crazy claims. Our v6 battery lasted 7 years so I reached out to dyson and 3min online chat later had a 20% discount and free shipping which closed the margin to only $20cad than the Amazon option, so going genuine. But serious thanks to your efforts proper analysis.
Can you be so kind to help with silly problem:I don’t remember which Dyson I have V6 or V8. How to solve this ?
Thankfully
Simon
Hi Simon. If you take the cup off your vacuum there will be a manufacturer sticker that should say SV04 (V6) or SV10 (V8). Hope that helps!
Very interesting! The local vacuum store " recommended" the First Power. But when I checked the reviews on Amazon there were lots of returns. However, the customer service was rated as superb. That is, they will easily replace any defective batteries. Going by reviews, I went for the DEWOKI. I have not installed it and know nothing about batteries and AMPS. Any thoughts? Thanks for a great video.
I have never disassembled a DEWOKI, so I couldn't speak to it's quality. Hopefully it ends up being reliable for you!
Thoughts are that all those people don't know anything thing about batteries and would rather not write any reviews at all because all they have to say is of no value, those reviews have no meaning
Ive purchased the knock off made in China batteries and they outlast the OG Dyson battery every time,the massive over rating of the amp hour ratings is getting way out of control now
I totally agree on the amp hour ratings... maybe these videos will help make some kind of difference!
@@HouseOfVacuums I just replaces a OG Dyson V8 22.6v 2800mAh battery with a eBay Fake Dyson V8 22.6v 9000mAh and i'm getting basically the same run time on full power. I would love to expose this fraud on eBay but I know the sellers have really good legal protection and angry lawyers. It seems on eBay you really require extreme buyer beware on any style of purchase. The site seems to promote some really shonky dealers.
@leokimvideo why would you want to expose them if you just said the battery was better?? Confused
What is estimated cost of these replacement batteries:
Full set( Cover ,PCB board, etc.) retail price of V6 (without battery): :USD 6
Total cost : Full set with battery cost :
1)First power : USD 30 .
2)Dutyone: Grade A cell from factory : USD 15 , Grade B cell from supplier : USD 10
3)Lekzai : USD 12, GZNS battery normally rated 3-5C , its for e-bike battery (multiple parallel ) most of cell rated on 10A or below , not suitable for high rating vacuum with 1P
Those price(without couting the shipping and assembly cost) . calculated from good star rating China supplier from 1688 and it's with minimum qty of 5-10.if qty is more, the cost will be much more lower .
Note: First power : USD 30 . the price may not accurate , Molicel is not as popular as Sony , samsung LG etc in China , the original price is relative high.Those cell info is covered/ removed , cell may not Grade A cell from factory , Grade B cell price much different
Thank you for the insight!
7.2022 FOUND THIS WITH 9000 RATING. Is it better? 5.0 AH is better than 4.0 AH?
More Ah will give you more run time. However, what you need to watch out for is manufacturers inflating that rating. As you saw in the video, most of the replacement manufacturers over-inflate their battery pack's capacity. Hope that helps!
Would have been great if you had run a new oem battery against them.
Indeed. However, during the supply chain issues recently new OEM batteries have become almost unobtainium. Thanks for watching!
I got a first power and that was a mistake. Worked fine for a couple uses and then acted like the original Dyson battery that I had for years and would only run max mode for 3 seconds and cut out. Normal mode a minute if I was lucky. Turd cells.
Great feedback! Unfortunately, anything power with lithium ion cells has the potential to run into these issues. Particularly until vacuum manufactures start designing their battery packs with the care that power tool brands do. Whether replacement or OEM, vacuum batteries tend to be cheaply made and a reliability crapshoot. However, based on the cells themselves, I do still believe the FirstPower is a cut above the other replacement batteries. Cheers!
I'm so happy to know the best choice still kinda sucks lol.
Yeah, it's unfortunate but I have to tell it like it is. Thanks for watching and the comment!
MFW I just bought a "9000 mAh" battery for our V6 (for A$29).
It appears that I'm going to need to find a way to verify the actual capacity - preferably without having to tear-down the battery pack.
I'm not asserting that the vendor is falsely advertising, but if it's 9aH the V6 should run for more than half an hour based on the experience of the tests in this video.
Fortunately, if it doesn't yield results that are close to spec, Australian Consumer Law (ACL) is *brutal* for sellers who make false _or misleading_ claims about the stuff they sell.
Even if the battery is true to capacity, but results in unsafe operating conditions (e.g., overheating), the fact that the vendor claims that it is suitable for our model, exposes them under the ACL - even if they're located outside Australia.
Just to be sure, I always tick 'Australia Only' in the search sidebar on eBay, and "Ships from Australia" on Amazon.
I would agree, there is almost no chance that the pack is 9000 mAh. There isn't even a battery I'm aware of in either the 18650 or 21000 form factors that gets anywhere close to that number. And since the batteries are wired in series, the voltage increases with each cell added, but the capacity remains the same, so 6 2100 mAh cells in series is still 210 aAh.
Very interested as to whether you get legal traction on that. I'm not familiar with the Australian system, but would love to hear back if you pursue it. Cheers!
First power's 4.8Ah battery is cheaper than their 4.0 for some reason and has pretty bad reviews. There are even pictures of the unit catching fire!
It's a good point. The unfortunate truth is that many sellers game the reviews. I use a browser plug-in called Fakespot that will tell you whether or not the reviews on an Amazon item are reliable. First Power's are typically graded as an A or B, meaning there is little manipulation, so you are getting real opinions.
The second reason is sample size. The First Power 4.8Ah has over 800 reviews, meaning you are getting a better data sample. It is much harder to call listings with 50-100 reviews as representative.
Ultimately, you can't beat the OEM Dyson batteries for quality and safety. Out of all the replacement batteries I've seen, the First Power is the safest ONLY based on cell safety alone. But when a replacement costs 1/3 of the original, you are certainly giving up quality somewhere. Could that cost cutting have caused the fire in the one review? Certainly. Which is why I always add the caveat that if you don't want to take chances with safety, you get the OEM every time.
Hope that helps. Thanks for the comment!
Why are the reviews for the 'best' one so bad? I wonder if they changed the cells they used it something because people seem to really hate this battery pack and there's a review where it seems to have caught on fire.

@@HouseOfVacuums Yup I just ordered 2 of them, and by the sounds of it they took advantage of the great initial reviews and then swapped for cheap generic cells, they are no where near the rated ratings and they don't even last as long as stock, over a minute less in full power and 3-4 minutes less in low power! Shame!
When an 8 year OLD oem battery outperforms half the new batteries, I would love to see how a NEW OEM battery performs?
One of these days this one will fail and I'll be able to justify a new one to benchmark. Thanks for watching and commenting!
@@HouseOfVacuums So it would seem then that genuine Dyson batteries are by far the best, but are they best by runtime per dollar? And lifetime hours per dollar?
I felt like runtime was not good to start with so I came looking for longer-running compatible batteries. Like how you get so so so much better value with non-genuine printer ink/toner cartridges. No way am I going to spend a cent on lower-capacity batteries.
The main issue I have is the battery running out before finishing vacuuming and having a patch or whatever of dirty area left and having to wait for the battery to cool down and then recharge.
I guess the best options are:
1) revive the screws, get a second genuine battery, and swap batteries half way through vacuuming;
2) buy high quality cells in serial sets and wire the sets together in parallel with the original and seal in a neat case. Kind of like the one you reviewed but using quality units.
So, boiling all this down to the most succinct executive summary, the winner is:
FIRST POWER.
Is that right? Why not rank all the replacement batteries you tested from first (best) to last (worst)?
I would get an OEM but Dyson is all sold out of the V6 models.
Yup, that's the verdict! I purposely didn't rank them because I would simply classify the HSW and Lekzai are definite "do not buy" models and the DutyOne is on the cusp. The FirstPower is the only one I would recommend based on the cells, performance and build. If anyone wants the rundown, check the results at 15:01.
Thanks for watching and commenting. Cheers!
I have bought a MCWGOLD would it be safe what is your verdict.
@Rubina Ali I have not tested that particular battery pack, so I really couldn't say with certainty since the quality on the Chinese packs are wildly inconsistent.
Why don't they make the battery packs with simple drop-in battery replacement cassette? So much unnecessary restrictive packaging!!!
All I want to see is how to install my replacement battery
That was not the purpose of this video, however if you search for "replace dyson v6 battery" the first response is an instructional from Dyson.
i was lured by the fake battery too. my conclusion is just buy the genuine item. unfortunately my oem did NOT last anywhere near 8 years, not even 2 or 3, which angered me giving the high price of these machines and persuaded my decision to bypass dyson's overpriced battery and go straight for a counterfeit. The counterfeit lasted a matter of months before showing rubbish performance and now it is acting very strange indeed with 3 cutouts before working normally??? but with a reduced runtime. I think it's better to just bite the bullet and buy an OEM dyson battery. They are all lying excessively about the mAh anyway so better to just buy the original.
Thanks for watching and commenting!
I always tell people that if you want the safest and most vetted product, just go OEM when available.
What do you folks think? Would you go with the First Power, OEM or another option? Let me know!
Gona try first power.Thanks
Reviews don’t look good unfortunately.
I'm trying to find a replacement battery for my V8 Absolute. OEM direct from the website is out of stock. Going off your review for the V6, I looked up the FirstPower V8 batteries. And it doesn't seem like they review farmed their product. Where as the other ones on Amazon have hundreds of fake reviews. No reviews on the FirstPower of it blowing up yet..
Going to take the hit and buy it. See what happens. It seems the main issues with non OEM batteries are that they eventually just die, the vacuum runs on its own eventually and burns out the motor/battery, and people are unsure if it stops charging when full.
My V8 barely runs 10 minutes on low, before running out.
:(
Wish me luck.
Thanks for the review!
Gona just get oem.
I went with the First Power from Amazon, and unfortunately they cheapened out and went with crappy cells, no longer using Molice cells, it didn't even outlast the stock ones! Even on the cells its stamped "RH YG18650 TZ10C 21AP" whichever that is but nowhere near stock!!! I guess gotta start over and research for some good ones again!
If you want to improve these videos please cut the awful music and the logos, you are not IBM and just get into it as you are wasting the 60s preview, if you want the logo stick it at the end so you don't block your own content with related videos . Otherwise a good video
Thanks for the comment!
What is wrong with your lighting, keeps making light and dark patterns on the carpeted table. Very annoying, like I'm suffering heat exhaustion in the desert or something. Also, try not to use such a complex carpet design because it uses up a lot of the video bitrate, reducing the quality of everything else at same bitrate. Lastly, all I wanted was a spreadsheet listing the brands/models, listing the battery, listing rated current, achieved runtime, rated runtime, and cost. That ONE spreadsheet would be better than 18 minutes of talking.
What is wrong with your typing? There are so many letters, it's giving me a headache. If you could present your paragraph to me in a Powerpoint deck, that is actually what I wanted. Not ONE giant paragraph.🤣
@@HouseOfVacuums Maybe more effort on videos and less on jackarsism?
@@stinkycheese804You wanted a spreadsheet on TH-cam? 😂😂😂 Wrong platform... And if you are not happy with the effort and choice of the content creator video style you could always get off your butt and do your own testing, creating your own spreadsheet instead of b*tching about someone else's efforts that don't match your demands couldn't you?
Let's be honest the v6 is garbage I've gone through 2 motors and 1 battery pack. Not worth the constant breakdown in my opinion
Wow, that's intense. I've had two V6s hanging around for testing, one of them has to be close to 10 years old. I've replaced one battery so far.
That being said, they do take some effort to maintain. Charging directly after vacuuming, leaving the battery on the charger, letting the vacuum fall, having clogged cyclones... a lot of things could have contributed to those failures.
If you want a cordless that is crazy easy to maintain, check out the Riccar R10CV.
They are all sh!te, including Dyson batteries (especially if you use max setting much), because Dyson didn't implement a cell balancing circuit. I have power tool batteries 10 years old (at least 1000 cycles) that still have about 60-70% capacity. I didn't even get 50 cycles from a couple of Dyson batteries, before the run time was considerable less and max setting would only work for a few seconds before cutting out. The after market battery had the same failure, only much sooner. I know it is a balancing problem because I took the packs apart and found the cells to be extremely out of balance. Such a state will not allow the battery to fully charge and the safety circuit will shut the power off very prematurely. Resulting in pathetic capacity. I balanced the batteries with a hobby charger and they work as they should.
The only problem is that there isn't enough room inside the battery to add a balancing port, so the batteries can be rebalanced (easily) again after several charges. Dyson uses quality cells, but it's a moot point if those cells become out of balance (and they absolutely will in a series configuration) and there is no balancing circuitry.
I agree that it is a balanced charging issue in part. If you have no balancing and weak cell, eventually the voltage on that cell will drop so low that the BMS won't allow the vacuum to turn on due to a "low voltage" condition. If you happen to get well matched cells. from the factory, this can be avoided. I got a V6 battery that is at least 7 years old and keeps cranking... so I got well matched cells that haven't fallen out of voltage spec yet. So it is largely luck of the draw.
In either case, if vac manufacturers are going to continue to sell vacuums, I would hope that they would start building better packs with correct BMS and balancing like power tool companies. Unfortunately, I think that would push the cost of the vacuum above what consumers would be willing to accept. I don't see the vac industry changing any time soon.
If you want to see a great vac battery design, check out my tear-down of the Riccar Superlite Cordless battery. Cheers!
They are crap,Dyson v6
what's 120F in science?
322 Kelvin :-P
