What size of battery does my hearing aid need?

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 10 (yellow)
  • 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.

How do I store and use hearing aid batteries?

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.

How long will my hearing aid battery last?

Hearing aid batteries can last anywhere from a couple days to a couple weeks. Rechargeable hearing aid batteries are also an option for most newer hearing aids, check with the Audiologists at Mile High Hearing if you are interested. Always make sure to check the expiration date located somewhere on the packaging before you purchase hearing aid batteries. We recommended buying hearing aid batteries that have an expiration date that is further out than 2 years. There are many factors that influence the amount of time your hearing aid batteries will function including: 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. Where you store your hearing aid batteries will also impact their lifespan. Store them 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 1-800-498-86666.
