Dyson V8/SV10.... 15 mo ago i got an OEM replacement battery direct from Dyson, but it's already dead (it only flashes red a few times then nothing). I's prefer to not give them another $130 (esp since it's not our 'daily driver' vac anymore), but so many people here say to avoid 3rd party. I thought about replacing the cells but then reading about BMS auto-locks. So what do i do?

Are there any 'ok' 3rd party recommendations y'all can offer me? or any other ideas?

I actually just spent 45 min on the phone w Dyson support (thinking it was covered under a 2 year warranty) apparently not. And not sure why i needed 44 minutes to be told that.

btw do their batteries have a 'use it or lose it' aspect to them? Do they last longer when exercised regularly?

EDIT: ended up ordering one from Amazon "POWTREE Upgraded 6000mAh V8 SV10 Battery 215681 Replacement Compatible with Dyson V8" for $40. So far so good.

I am disappointed that the battery on my V8 Animal is already dead after 2.8 years. I use it only as a backup (aka light use). Seems like power tool batteries last much longer under much more heavy use.

In any case, I need to replace the battery. There is the super expensive Dyson replacement and 3rd party Amazon's. Looked at some reviews. Is there any reason no to pick a 3rd party? Is there a known incident of a 3rd party pack to go up in flames? Frankly, this would be the only reason for me not to go with 3rd party.
