Do hearing aids use special batteries?
Yes. They use hearing aid batteries. There are a number of sizes of disposable hearing aid batteries available. However, yours will become easy for you to identify. They are all color coded with the same size corresponding with the same color across all manufacturers. Your Doctor of Audiology will counsel you on which battery is the correct size for your hearing aid. Rechargeable batteries are also an option. They are included in the hearing aid and may not be changed or accessed by you. In fact, the case on the hearing aid does not even open!

A standard disposable battery will last approximately a week when used all day every day. However, don’t let that run time discourage you! Batteries are available at all major retailers and your Doctor of Audiology will teach you how to change the battery. Additionally, don’t be shy about using your hearing aid. If you peeled their stickers off to activate the battery and left it sit on the table (without any use), the battery would only run about 2 weeks.

The biggest benefit for many patients is that you don’t have to worry about changing a battery. As long as you remember to charge it when you go to sleep each night, it will always be ready to run in the morning. This makes it perfect for people with dexterity issues, as well.

[Top of Page]When do I change my my hearing aid batteries?
Hearing aids have a built-in battery warning. Your hearing aids will alert you when the battery is low and needs to be changed or charged. For disposable batteries, this is approximately every 7 days. Another good way to check to see if they need to be changed is to scratch your head just above the hearing aid. If you can hear the scratch, you know it’s working.
