Types of batteries

There are several hearing aid battery types and sizes that are color-coded for easy identification.

Thin Foil Technology (TFT)

These batteries are the latest development in the market with a very high energy density, providing more capacity and a longer battery life compared to other well-established hearing aid batteries by up to 15%*. These batteries have been developed to support individuals who wear hearing aids meet modern-day challenges, and allow wearers to enjoy long conversations, hours of streaming, and everyday life. Ask your hearing care professional for Phonak private label batteries with this state-of-the art technology.

Mercury-Free Zinc Air

These environmentally friendly batteries use air as an energy source with a tab that seals the air holes. Once the tab is removed, it takes about two minutes before the battery is activated. If it’s not activated correctly, the battery could get damaged and won’t have the required voltage level to work properly. These batteries have a minimum shelf-life of two years, and when you’re ready to dispose of them, it’s recommended to recycle.
A variety of micro batteries are available at our hearing care professional network, please ask your provider to find the best and most convenient solution for you.

Rechargeable ACCU Plus

These high-quality, reliable batteries are fast-charging, high-performing, and can be used in most hearing aids. They don’t contain any heavy metals like mercury, cadmium, or lead, and are subject to strict safety and quality checks. They also feature a quality seal to guarantee maximum product protection, as well as a re-closeable clip to keep them safe.

Extending the life of your batteries

From incorrectly storing your hearing aids, to not waiting long enough for the battery to activate, there are a few things to be aware of when making sure your batteries last and work as long as possible.

Proper care and handling

The running time of your hearing aid battery depends on several factors, but there are ways you can extend it with proper care and handling to get the best performance out of your batteries.

Factors that can shorten your battery’s running time:

  • Hours of use per day
  • Streaming mode, which requires more battery energy
  • Exposure to moisture
  • Incorrectly storing the hearing aids in the wrong temperature, a warm, humid environment, or near metal objects such as keys 
  • The type and features of the hearing aid being used
  • Improperly activating the hearing aids after removing the battery tab

Troubleshooting and safety

Despite getting a new battery, it’s possible that you could still have problems with your hearing aids not working. Luckily, there are steps you can take to troubleshoot your issues before going to a hearing care provider.

Factors that can stop your hearing aids from working:

  • Not waiting enough time for the battery to be activated after removing the tab
  • A dented battery surface, which causes poor contact with the battery terminal of the hearing aid
  • Build-up of dirt on the battery terminal of the hearing aid
  • A dead battery, which can happen when it’s not activated correctly
