Been using hearing aids for several weeks that run on size 312 zinc-air
button batteries. They last about a week then go dead along a very sharp
discharge curve.

When I used those, I would remove them from the hearing aid at night
and place them, vent hole down, on a smooth surface. They lasted much
longer.

Gun control is like trying to reduce drunk driving by making it tougher for sober people to own cars.
