Hearing Aid Batteries
There are two types of batteries used in hearing aids, rechargeable and disposable. Newer hearing aids often come with rechargeable batteries. With these batteries, they generally require a nightly charge, just like other electronic devices.
Disposable batteries are zinc-air button batteries. Since these batteries are air activated, the come with a sticker on them. This sticker enables them to have a very long shelf life, approximately 3 years at room temperature. Storing in the refrigerator can lower this shelf life as condensation can form under the sticker.
