The typical size 312 disposable battery will give you approximately 5-7 days of battery life.  While this may seem like it isn't very much, just remember that this tiny battery needs to power a tiny computer that is constantly processing sound.  How do disposable batteries work.  Since Mercury was eliminated from hearing aid batteries, the primary chemical substance is Zinc.  These batteries are often called Zinc-Air batteries because 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.  What will affect battery life?

1. Severity of Hearing Loss

2. Battery Size
