18650 go BANG! :o(
plugged in my charger last night and a bright flash, big bang little puff of smoke and tripped all the sockets in the house… Why?
Battery was a trustfire protected one (Blue) and it’s only the second time it’s been charged, I was using the charger with a universal adapter, is it possible to get the polarity wrong?
got it all from DX at in December.Posted 9 years agoMrNuttMember
oh dear, I’ve gotta say I do get the fear with these batterys, that said I do ride around with one on my bars (kind parallel with my wedding tackle) and another tied to my head, both in metal tubes with no obvious sudden "pressure release" capability, essentially a potential pair of pipe bombs!
but hey, times like this I often ask myself: What would WCA do? 😀Posted 9 years agopk-ripperMember
mine have been fine thus far. That said, the 18650 batteries do have a history and reputation of being "explosive", so I’ve always been slightly sceptical of them. My charger has been ok though.
personally, I wouldn’t use the batteries that were in the charger when it went.Posted 9 years agotwohatsMember

It’s not unknown for this sort of stuff to be spec’d on the old european voltage stabdard (230 +/-6%) rather than either the old UK spec (240 +/-6%) or the new pan-european including the UK spec (230 +10%/-6%). When they changed the standard they changed it in such a way that we in the electricity companies didn’t need to do anything, old equipment would still work but equipment suppliers had to increase the tolerance that their kit would work over. If they didn’t then someties things fail.
That said I am assuming there is a decent regulated power supply in most chargers (they’re pretty cheap) and it would surprise me if one I bought failed.
So maybe it was just a duff one – contact the seller and see if they’ll honour whatever king of warranty a Hong Kong internet seller provides.
