leaking/corroded 18650

Luckily of the 50 or so laptop pulls that I have this is the only 1 that’s physically gone bad on me. I check them yearly but perhaps I should check them more often. Now that I think about it I have a bunch stored with my earthquake supplies (checked semi-annually) so perhaps I should store new batteries instead. The reason I haven’t is that seems like a waste to store good batteries which will likely never be used. Then again none of my emergency supplies will probably ever be used :partying_face:
