Been using hearing aids for several weeks that run on size 312 zinc-air

discharge curve.

I measured some used ones in a battery tester and their voltage has
returned to normal- around 1.45v. Not sure how long they'd last if tried
them back in the hearing aids- or it's a good idea to put them in there.

I think it's highly unlikely they'll have any significant load capacity
but can't see what harm it could do to try.

Saw interesting whitepaper
