Dyson V8 (215681) Battery Disassembly

- A brief video I recorded after dismantling my Dyson V8 battery to recover the 186500 cells, apologies I didn't record this as I did it, but as I couldn't see any other videos on RUclips I thought it may help someone else.

No problem that you didn't film the actual "breaking it open" , this is very helpfull, thanks!
Some folks have replaced the weak cell or all cells in this battery pack, though the price of an aftermarket replacement battery pack is reasonably priced.. Thank You
Thx for the video. The battery is the 20700 (20mm x 70mm) size not 18650 (18mm x 65mm)
Great video. Just a little correction, joints between batteries are spot welded. So you cannot desolder.
Appreciate that 👍
So if I was to take them apart, what would be the best way to get them back? Can I try to solder them back and hope that it would hold? Or can you recommend something else.
@@aajeev get a spot welder and spot weld it. I am not saying you cannot solder because you can but batteries do not like heat. You need to have a proper preparation and a quick as possible solder solution. Also keep in mind soldering batteries not safe and could be dangerous. Use all PPEs.
@@helel78 thank you. Appreciate you sharing your experience.
Very useful Thanks.
Those batteries are not soldered, they are spot welded, DO NOT apply heat to them thinking they are soldered, it may short the cell and cause it to burst
Also, unwise to pull off the metal welded to the cell as it can easily pull holes in the sealed cell. By the way, they are not 18650 but 20700 - bigger !
Gutes Video, greetings from Germany...
Thx mate!
Great video dude
Thanks for the video. My two year old original Dyson V8 battery pack still has good capacity, but it’s become slow to recharge. I assume one or more cell became weak and the BMS is doing some balancing each time it’s charged. I suppose there’s nothing to be done except recover all the cells and individually test them for capacity.
That's a great start tq.
I’d love to know what tools you think could use to open this without damaging it. I had all these tabs wedged and it still wouldn’t budge a millimeter. Mine was glued closed..
I think you could probably use the plastic tools you use with car panels and mobile phones, just needs to patience 👍
Robert Jones Nope. I’ve dismantled cell phones and gaming systems before. I have pry tools. This was glued inside.
Even harder then, I had no glue! I notice there are heating pads available for removing iPad screens etc, so I guess depending on the type of glue, heat may be an option, but could be it's becoming unserviceable.
Robert Jones yeah pretty much impossible to not break to open. Stinks.
It's a disappointing trend these days with expensive items to prevent repair isn't it!
Has anyone had any success with the £30 ebay replacement packs?
If just replacing individual cells then do they have to be Dyson branded?
I've been using aftermarket batteries on the older DC34, DC35 and V6 for several years now. They've proven to be very good in terms of both reliability and run time. I can especially recommend these brands: Floureon, FlyLinkTech and Flagpower. To replace just the cells you would need high-drain ones but any brand should be fine.
Thank uou
Why would you need to recover the cells? They are expired-- I missed that.
Why not 😉
