Hearing Aid Batteries

The most common type is the zinc-air button disposable battery. Traditional hearing aid batteries were produced using trace amounts of mercury to assist with conductivity and stabilize internal components, but mercury is no longer used in hearing aid batteries. Zinc-air batteries remain stable for up to three years when stored in a room temperature, dry environment.
