Everything You Need to Know About Hearing Aid Batteries

Hearing aid batteries use zinc-air technology. What is zinc-air technology? As the name implies, zinc-air technology uses oxygen from the atmosphere as an active ingredient. There are some other unique aspects that make zinc-air batteries different from other types of batteries:

Need for a Sticker/Tab

Hearing aid batteries need a tab or sticker to seal the vent holes in the battery and prevent dry out. Do not peel off the paper tab until you are ready to change your battery.

Letting Your Hearing Aid Battery BreathLet the Battery Breathe

This is very important. Once you peel off the paper tab, it is important to let the battery “catch its breath.” As air starts to enter the holes under the paper tab, it activates the battery. We always recommend that you let the battery sit for a full 3-5 minutes before you insert it into your hearing aid and shut the door. That is important because it allows the voltage in the battery to rise and ensures that you will not have start-up problems with the hearing aid.

Use Right Away

Zinc-air batteries are best used right after you peel off the tab. This is because the battery begins to discharge as soon as that tab is removed. It is impossible to stop that discharge from occurring once you have removed the tab. Replacing the paper tab will not stop the battery from draining.

Environment

Battery performance, and ultimately hearing aid performance, can be sensitive to the environment. Heat, cold and humidity all can affect the life of your battery.

Reminders

:

  1. Keep on the paper tab until ready to use.
  2. Once you peel of the paper tab, let the battery breathe for 3-5 minutes before you close your battery door.
  3. Batteries will slowly drain as soon as you remove the tab even if you are not using your hearing aid.
  4. Keep your batteries in a cool and dry place.
