Our zinc powder/electrolyte plus provides superior battery life and battery freshness is guaranteed! Zinc-air batteries use air as a source of power. Each battery has a factory-applied tab that seals the air holes in the battery to ensure freshness until you are ready to use it. Each Interstate hearing-aid battery pack is stamped with an open freshness date to ensure that you always receive fresh batteries.

We also carry Energizer brand hearing aids with the EZChange dispenser.

Did You Know?

Once the tab is removed, the battery should not be installed into the hearing aid for several minutes to allow the battery to reach full capacity. Hearing aid batteries should always be installed using a clean cloth or an applicator as oils from your hands can create a layer of resistance between the battery and the hearing aid. This resistance will cause the battery to work harder and fail prematurely. After activation, allow battery to rest for 15 minutes before installation.
