Comment on is our battery/junk drawer dangerous?

It’s fine. Even if they were lithium batteries —still fine. See battery manufacturers actually design batteries specifically so that they don’t fail catastrophically (🤯 crazy right?) but it’s true. Turns out they have whole-ass warehouses full of them.

Obviously it’s possible for lithium batteries to fail catastrophically, but this isn’t a typical failure mode. Generally catastrophic failures happen when a battery is damaged and or under load.

Typical household batteries are not as energy dense as EV batteries. And are not packed as densely such that a single cell puffing won’t cause a cascading failure.

I do recommend keeping them in bags to contain leaks, coin cells are generally already well packed, but it can’t hurt. It’s also not a terrible idea to write the date you bought them on the bags and properly dispose of them after ~5 years.

damn your preemptive hyphen preventing me from reading it as ass-warehouses and chuckling to myself

  I mean… there’s that company big ass fans, I feel like they definitely refer to it as such ;-)

I’m not a chemist or ‘battery scientist,’ but I understand that Li+ ion cells can indeed be heavily damaged without showing any outward traces of such. That is, internal filaments can build up over time, and a damaged cell can be at risk when charging (as you note above, I believe).

That said, there may be associated swelling that tends to indicate such damage, but I’m not sure that’s always true. A cell with a cheaply-made casing would be a combined risk.
