Sound Advice: Battery Brief

Updated: Mar 29, 2019

Understanding Your Options


Can I use any battery with any hearing aid?


Generally, yes. Although the quality may vary between manufacturers, the sizes are standard. We will always make a battery recommendation for you based on your individual situation.


Do hearing aid batteries come in different sizes?


Yes. Hearing aid batteries usually come in 4 common sizes: 10, 312, 13 and 675. Most manufacturers use an industry standard color code on their packaging to make the size easier to identify.


“I highly recommend the new Rayovac batteries. They last 2 to 2 1/2 days longer, depending on the amount of streaming I do. And I wear my hearing aid a minimum of 15 hours a day!. I’m delighted.”

How long can I expect my batteries to last?


There are a number of different factors that determine the life of your hearing aid batteries:

  1. The type of hearing device you have

  2. The type of batteries you have

  3. The number of hours you use your hearing aids each day

  4. The way you use your hearing device – if you do a lot of streaming, for example, your batteries will be working harder



How should I take care of my hearing aid batteries?


There are several things you can do to extend the life of your hearing aid batteries:

  • Store them at room temperature. It used to be that storing them in the fridge would help them last longer, but today’s batteries are powered by zinc air and will not benefit from colder storage.

  • Speaking of zinc air (which just means using air as the energy source), you should keep the plastic tab on your battery until you are ready to use it. Pulling it off exposes the battery to air, which essentially turns it on.

  • When you are not using your hearing aid, turn it off and store it with the battery door open. This will allow moisture to escape so it won’t damage your device if left for a long period of time.

What about rechargeable batteries?


Definitely an option! Both Oticon and Signia offer hearing aids with the option of rechargeable batteries, which are a great fit for many people.
