Hearing Aid Batteries – Do’s & Don’ts
The typical size 312 disposable battery will give you approximately 5-7 days of battery life. While this may seem like a short time, remember that this tiny battery needs to power a tiny computer that is constantly processing sound.
Disposable hearing aid batteries are often called Zinc-Air batteries. The primary chemical substance in disposable hearing aid batteries is zinc and when you remove the sticker/tab from the back of the battery, air mixes with the zinc creating an electrical charge. This 1.45 volts is strong enough to power your hearing aids.
