> So, I'm quite happy replacing my own phone battery with reasonable precautions, but no, friend, you may not charge your sketchy e-bike in my hallway.

Having myself witnessed a cell phone's battery go up when it was nicked during a removal, I'll take the candle a thousand times over one of those. But you know what you know.

Personally I just wouldn't fuck with re-manufactured batteries at all. Batteries should be new, from licensed factories, and they should be recycled in a way akin to car batteries so we don't lose all the lithium inside that's still perfectly good for another go-round in a new battery.



Yeah, i know the risk, that was my point. Given the difference in frequency (say, ~every day vs. ~once a year) and level of attention, the risk to others is at least comparable.

Given how popular DIY phone battery replacement is, you'd expect there to be at least a few incidents reported if it was a major risk, but I just don't see them. On the other hand london fire brigade reports 200 candle fires a year...
