It is important to make sure you correctly dispose of your hearing aid batteries.

  • Keep out of reach of infants and children
  • Make sure batteries are secure in the device
  • Do not leave batteries out where they can be mistaken for medicine or pills

Proper use of your hearing aid batteries

Remove the drained battery from your device, then:

  • Spin the dial on your hearing aid battery packet to position a battery over the packet door
  • Open the door and remove the hearing aid battery from the packet
  • Re-close the door to ensure the batteries remain clean, secured and protected
  • Remove the battery tab and let it sit for one minute to allow air to activate the battery
  • Insert the battery into your device with the flat side facing up, then close the device door

Your hearing aid should now be powering up and ready for use!

Storing your hearing aid batteries

Store your batteries at room temperature. Avoid extreme temperatures, heat will shorten the life of the batteries and refrigeration is not recommended. Avoid carrying batteries in your purse or pocket because metal objects such as keys or coins can short out batteries.

Do not leave batteries in your hearing aid if you do not use them over a long period of time.

How long do hearing aid batteries last?

Battery life is determined by the type and amplification of your hearing aid, as well as the hours you wear it. Because this varies from person to person, we suggest you consult with your hearing professional so they can properly determine the expected battery duration in accordance with your lifestyle.

For more information on batteries specific to your hearing aid, refer to the hearing device manufacturer's manual or website.

How do I know if the batteries need changing?

Depending on how often you use your hearing aids, you may need to change the batteries weekly, fortnightly or monthly.

You should change your hearing aid batteries if the sound becomes distorted or you have to turn up the volume on your hearing aid more than normal, or if the low battery beep or voice sound comes on, indicating that the battery is low and should be replaced.

Why is there a tab on my battery?

Zinc air batteries use air as an active ingredient in fuelling the battery. The tab provides a seal that ensures freshness until the time of use. Once you remove the tab, the air from outside of the battery begins to react with the zinc inside of the battery. This reaction is what powers the battery.

To properly activate the battery, remove the tab and wait one minute to allow air to fill the battery, then insert the battery into your hearing aid.

When the tab is removed and the battery has been aired up properly, make sure that you are not forcing the battery door closed. Check that the battery is inserted correctly before closing the door.

Note that replacing the tab when the battery is not in use will not extend the battery life.
