There are four different sizes/numbers/colors when it comes to hearing aid batteries. If you are unsure which battery your hearing aid needs, please consult with one of our Audiologists.

  • Size 312 (brown)
  • Size 13 (orange)
  • Size 675 (blue)

Your Audiologist will show you how to change your hearing aid batteres. Do not force the battery door closed if it does not close with ease initially.

Hearing aid batteries are zinc-air, which means they are powered by air (oxygen). A small sticker keeps it sealed from air and fresh until you are ready to use it. When you are ready to use a new battery, remove the sticker and wait 2-5 minutes before you place it in the hearing aid. This allows the battery to become fully charged, providing you the best battery life. Hearing aid batteries can last anywhere from a couple days to a couple weeks. There are many factors that influence the lifespan of your hearing aid batteries. Hearing aid batteries can be affected by the size of the battery, amount of hearing loss, amount of time the hearing aid is used, humidity, temperature, altitude, wireless streaming, and personal listening environments. Hearing aid batteries should be stored in a dry, room temperature environment.

CAUTION: Keep batteries out of reach of children and pets. If swallowed or inhaled, they can cause serious injury. If swallowed or inhaled, contact the National Battery Ingestion Hotline at 1-800-222-1222 or collect at 202-625-3333.
