PowerOne Size 312 Mercury Free 60 Pack
PowerOne Size 312 mercury free hearing aid batteries come in a pack of sixty cells for adult users. The zinc air chemistry activates when the tab is removed. Each unit is new and ready for daily use in compatible hearing instruments.
Practical Limits of Zinc Air Chemistry
Zinc air cells require air exposure to generate voltage after the tab is pulled. Shelf life shortens once the seal is broken and performance drops in very cold or very humid conditions. Users who need rechargeable cells or a different voltage must choose another chemistry.
