Tip
A ZINC AIR battery that has not been used yet, has a sticker on the backside for closing off the battery. Until the sticker is removed, the battery will not be activated. When you remove the sticker, air can flow into the battery, which will activate the battery. Before closing the battery compartment of the hearing aid, wait at least 30 seconds up to 1 minute to let the battery breath. When you do this, the lifetime of the battery can be prolonged extensively.

Oxygen to generate voltage
In a Panasonic zinc air PR312 battery, oxygen from the environment is used to generate voltage. The battery itself contains an electrolyte and a porous zinc electrode that permits air to flow through, the air being used as an electrode. In sealed devices where air cannot get inside, the batteries cannot be used because of this process. When the seal is removed, the generation of electricity starts. The production of Zinc Air batteries by Panasonic was launched in Japan in 1985.
