Another link about it on REecharge news
air/zinc batteries are the majority of the batteries used in hearing aids. A main reason is the very high energy density you can get from that technology at a reasonable cost. They are not rechargeable but very high energy density.
They have a cover strip that you remove to activate the battery and leave them exposed to air for a few minutes before installing them.
