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.

When purchasing hearing aids, Dr. Napoli will help you determine which type of battery is best for you.
