Dyson DC31 DC34 DC35 DC44 battery disassembly for replacement: Not Worth It.

[@nw8000]

You can’t buy genuine batteries from Dyson anymore so this really helped me to get the case open on mine. Now I need a video on how to diagnose what’s wrong with it. Good job thank you.

[@TheChug]

Thank you so much for the feedback. Glad it helped.

[@tasmedic]

Most likely it will be a simple matter of charging it up then running the appliance until it runs flat. Then check voltages on the cells. You could then try replacing the worst of the cells, although this would be tough to do, judging by the design. Looking at this excellent video, it would probably be easier to remove all the batteries, and the charging circuit, and replace with new cells plus a 7-way molex plug connected to the positive end of each cell, plus the negative end of the last cell. You could then use a standard balance charger to charge the thing up. Not ideal, as you'd have to charge the battery off the appliance, but it's what I've done with all my lithium cordless drills and it works very well, plus you can choose your own charge rate and use a top notch balance charger which preserves the cells. If you've multiple lithium ion devices, and you adapt them all to molex plugs, you'll be laughing!

[@nw8000]

@@tasmedic That sounds great! Have you done a video on how to do it??

[@tasmedic]

@@nw8000 Yes, I ought to do that. I've a couple of videos up about other things though. I wonder if you've seen those....?! ;-)

[@mrj1518]

It's highly likely these 18650 cells are low or faulty. These batteries only last about 2 years in the Dyson. In the UK you can buy Samsung 18650 cells from £3.79 each. Get yourself a multimeter and check each cell. But, to remove the cells and install new ones isn't for beginning. The cells need to be spot welded on back.

[@tromboneJTS]

It is nice that you are so gentle with it.

[@woodydroneson]

Just ordered a new battery pack, but interesting to see what was inside, I suspected the batteries would be standard 18650 cells, and they were, the soldering etc would make it difficult to repair, but not impossible :) Thanks for the video, I'll dismantle mine and see if any of the cells are usable for a torch or something :), but probably for the recycle bin!

[@JA-gu8zb]

Does the battery pack works after replacing the cells? Hopes the BMS will not brick like those in the V6 battery packs.

[@Jaang29]

thank you Chug for taking the time to pst this video, really like it, and useful, simple

[@fiveminuteman]

Great vid, least he's shown you how to remove the casing and what's inside. Probably saved loads of people time and given others info via comments section on what batteries to use.

[@TheChug]

Thanks man, positive comments are rare on this video haha!

[@phartblossum]

Thanks for the video. I realize many others have issues with it. But I simply wanted to see what things looked like INSIDE of a dyson battery pack. Plus how hard it might be to manually replace the batteries. So your video accomplished showing curious folks the guts of a Dyson battery pack. The 18650 batteries are quite popular these days. I see that people building DIY VAPING RIGS for 510mm cartridges use them . So, many 18650 BATTERY REVIEWS sites are out there. Showing different 18650 batteries reviews and ratings.

thank you for the effort. was contemplating whether to diy replace my batteries.your video saved me much time.

[@JonathanVaucher]

j'ai reussi a faire une belle job en utilisant un exacto au lieur d'un flat screwdriver et en utilisant des lames de rasoir de sureté pour commencer à faire levier avant de wedger des lame d'exacto pour chacune des 6 pins.... tres clean job mais ton vidéo m'a aidé.

[@svankervej]

In the beginning i could i could turn my DC35 on when i pressed the battery from the rigth angle. I did the replacement with LG HG2 but now i cant turn it on at all. The head can spin but the motor doesent start. I suspect the 3 little pins being the problem as they are measuring only 0,05 V. Should they output 24 volt or? Hope one can help :)

[@bobbykoulouris]

thanks for the effort.

[@Jaang29]

[@plcrawley7]

Hi I have a dyson dc 35 cordless and it's s withing off the same as yours but only seems to do it while I have the full pole attached .when I took the pole.off and checked filters it is working fine but once I attach the pole it stops working .any help .

[@bobyoung1698]

Not to be critical, but I thought that the battery case - as it was first shown, before disassembly - was a "plug and play" unit. The replacement battery includes the case.

[@liamcottell7491]

Tried for 15 Minutes and couldnt get inside yet! Thanks for the video showing it is possible with lots of scratch marks. I just wanted to repair the worn socket in the battery unit but might as well buy another battery. Any luck with the $25 knock offs, saw some place online asking $85 for a genuine one lol

[@TheChug]

I bought the cheap one and it's still working!

[@Chapter27]

Thanks for the video … at least it satisfied my need to pull it apart lol 😂

[@TheChug]

That's great! 😂

[@paolocorronca3855]

Christian I thought initially "such a novice!!!". Damn guys, it is really the hardest battery pack I ever came across. To open it you eventually ruin it. It is not because of the plastic clips, it is because it is damn tight (with foam tape to increase the friction even further!!). To those that are wondering. I just rebuild mine, replacing the original Sony US 18650vc3 (rated 1900 mAh, 20A) with 6 LG HG2 (3000 mAh, 20A). PROBLEM: the original Sony have a diameter of 18.2mm, the LG have a diameter of 18.5 (0.3mm more). Guys, they DO NOT FIT, you have to use the Dremel to re-bore the cells' case, or modify the cell case (like a did with a cutter). As a result, the battery pack will result bent, and you will have to close it with American tape. Is it worthwhile? Meh...

[@TheChug]

Haha, yeah, well... I know it's not pretty and it sure looks like a novice. Thanks for the comment. It's not worth rebuilding it...

[@paolocorronca3390]

Christian Galipeau seriously, initially thought “here we go. It’s just a matter of patience, this guy had none...” took me two hours to open the case, no matter the use of hairdryer to make the plastic softer... and eventually the cells that I had were slightly too big to fit... it’s really a risky exercise, because you have to weld over the battery and there is really little space. Risk of shorting is real.

[@remicourty9689]

Hello My dyson work and stope work and stop I try to clean the connector of dyson With screwdriver of the DC35 type B in the body and little bit in the connector of batterie And now my dyson don’t work totally Do you have solution ?

[@norbertbendl6076]

Oooh nooo, don't you ever use a screwdriver for tasks like this! Opening cases like this one is an art! 😏 Use a thin knife blade instead and carefully work your way under the clips. The plastic Dyson used is flexible enough to take the strain and not break. I just opened a similar case (DC62) with very little visible damage. Now I have to find a way to unclip the light guide for the LED indicator. Almost harder than opening the case 😜

[@TheChug]

Thanks for the hint!

[@Swenser]

Try car petrol to weaken plastic joints first with cotton buds

[@TheChug]

Great idea!

[@toddstube578]

I assume I should also get 24V out on the three metal contacts on the backside of the battery when it is just sitting correct? I get 24V out from the two main connectors on the top of the post but nothing on the three metal contacts on backside and suspect this is why the vacuum head works fine, but powered attachments don't work.

[@svankervej]

Hi did you resolve your issue? Im having the same issue, only measuring 0,05 V across the 3 terminals. Does anyone know how to fix?

[@randycollens2681]

@@svankervej the 3 terminals is for communication between the main unit and the battery. You won’t find the output voltage there.

[@treccobay5621]

Makes you think why Dyson did not design the battery pack where you can side in the replacement individual chargeable batteries one by one. Some one claimed Dyson do not sell the pack any more yet they are still advertising on their website. My main concern there are plenty available cheap compatibles for sale from China priced around £22. Just don’t trust the compatibles for this reason.

[@etiennemattei9631]

Hi, I've opened my D62 battery pack. It is slightl different of yours. Do you know the type of soldering, is it tin? Can I use a soldering iron ?

[@KegRaider]

All lithium battery packs are spot welded. You can solder, however, be very careful. I have done it plenty of times before, without issue. I scuff up the new battery terminals with a razor or file, then set my soldering iron to MAX heat (550 C), then on the newly scratched up area of the battery hold the iron and apply a gererous amount of solder, without making it flood inside the positive cap!. Do one end of the battery, then move to the next battery, giving them time to cool down before soldering the other end. Remember, be careful! They can explode.

[@wingleung22]

[@fast2valve559]

Are them 18650's? if so im gonna tear mine apart and put some of my panasonic 3400mah cells in it

[@zorki23]

No do not use these panasonic cells, they can't handle the discharge rate of this device !!!

[@fast2valve559]

Carsten Oschlies whats the current draw on the dc59. I use these batteries in my fenix tk75 which i figure pulls a pretty high current also. thanks for the heads up.

[@zorki23]

It has 100 watt so it consumes up to 33A, as far as I know. You have to divide watt by 3 but don't ask me why.

[@fast2valve559]

if its draws 100 watts at 22 volts it would pull 4.5 amps

[@zorki23]

Happy trying. Dyson builds in expensive Sony VTC4 cells which can handle 30A in long time use. They will do this for a good reason.

[@zorki23]

It is possible to refit this battery, but not easy. Everything is very tight. But buying a new one is not a better option: This device is to old, and so are the third party batteries you can still get. Nevertheless, it is worth it. Every new Dyson (or Dyson clone) ist much bigger and less handy.

[@warbabe81]

You have to buy the WHOLE unit! What are you doing man?

OnlineBackupServices yeah, I don't think it's easy to replace those batteries There...

[@Professional_Youtube_Commenter]

Have you attempted it? The problem is the genuine replacements are very expensive and the cheap aftermarket packs use low quality cells which will die after 1 year. The dyson use us sony VTC4 18650 cells which have high amp 30Amp. The aftermarket chinese ones use any old cells. It may be worthwhile finding a faulty aftermarket battery pack and put in sony vtc4 cells. The aftermaket packs might be easier to take apart and reasemble.

[@TheChug]

OnlineBackupServices no, I bought a cheap one on Amazon... works great!

I reckon this is potentially very dangerous. You risk damaging the protection circuit which prevents over charging and over discharging the cells. Failure of the circuit could lead to a fire.
