Two Parts:Knowing When You Need a New BatteryChanging the Battery

As any hearing aid user knows, hearing aid batteries will go flat at the most awkward times! This is a step by step tutorial on knowing when and how to change them safely and correctly without damaging the aid or battery.

Part 1
Knowing When You Need a New Battery

    Check the source of your hearing aid issues. You'll need a new battery when the old one no longer works. This may seem obvious, but you need to check that the battery is at fault rather than a technical glitch with the aid itself.
    • If you switch your hearing aid on and there is no sound, check the list below. If all this is fine, then you may need a new battery.
      • Is the tube blocked?
      • Have you inserted the aid properly?
      • Is the battery door closed with the battery in correctly?

    Look for a low battery signal. On many models your aid can make a noise when the battery is running low, to give you prior warning before the battery goes completely flat. Some models give you a countdown, with a tone at 30, 5, and 1 minute remaining of your battery life. This usually gives you time to obtain a fresh battery and change it.

    Follow up with any other issues, if it's not the battery. If you insert a new battery correctly and there is still no sound, contact your hearing aid supplier as there may be a problem with your hearing aid itself.

Changing the Battery

    Find a new battery in the correct size for your hearing aid. If in doubt, check on the web or in your hearing aid manual. Some providers (such as the NHS in the UK) will provide a battery book with important details when they issue your batteries.

    Remove the battery from the pack and take off the sticky tab from the back. This activates the battery. Do not do this too far in advance as the battery may lose power. Leave the new battery to sit.

    While the new battery is sitting, remove the dead battery. Open the battery door to your hearing aid, and the battery should come out readily from a bowl-like area. Turn the aid around to let gravity help if necessary, but if the old battery is stuck you may need to contact your hearing aid provider.

    Insert the new battery the correct way around so that the + and - terminals correspond with the aid markings. If you insert the battery backwards/ upside down, the battery door may not close or you may even break the hearing aid! The door should close without abnormal resistance.

Tips

  • Keep batteries with you at all times, such as in your wallet

Warnings

  • Dispose of used batteries safely, ideally in a battery recycling box
  • Keep new and used batteries out of the reach of children and animals, especially since they are very small and may present a choking hazard.
