Hearing Aid Batteries

Fully Participate in Conversations Again

Hearing aid batteries are essential to powering the circuitry that enables you to hear with your new hearing devices, and it’s one of the hearing aid accessories that we get the most questions about. Some of the newer models have rechargeable batteries, while many styles still require the use of disposable batteries.

How can I tell which kind of batteries my hearing aids need?

When you select your hearing aids, your Hearing Health Solutions audiologist will make sure that you know what kind of hearing aid batteries you need. Generally speaking, hearing aid batteries are color- and number-coded for ease in re-ordering. For example:


Blue = 675


Orange = 13


Brown = 312


Yellow = 10

How do I find out the color or number of my hearing aid batteries?

During your hearing aid fitting, your audiologist will show you where to look and how to change the batteries. They are labeled by color and number, so it will be easy to tell. But if you ever have any difficulties, please call us at 888-638-5095 or contact us below and we’ll be glad to help.

How long do hearing aid batteries typically last?
Accordion Toggle

For rechargeable batteries, most hearing aids will need to be charged on a nightly basis, but will last you throughout better part of 24 hours. Usually, standard hearing aid batteries can go for 5 to 7 days before you need to replace them, but the actual amount of time depends on several factors, including:

  • Battery size
  • Hearing aid model
  • The severity of your hearing loss
  • The sound environments in which you are using your hearing aids
  • The accessories you use with your hearing aids
  • How many hours a day you are using your hearing aids

The more demanding your sound environment is, and the longer you wear and use your hearing aids, the faster the battery will wear down.

Why do hearing aid batteries wear down so quickly?

That is a very common question, and people often mention that watch batteries last for years. This is true, but keeping time uses far less juice than the demanding functions hearing aids must perform with very small batteries. A hearing aid battery powers a microphone, amplifier and other complex functions, determining how frequencies are delivered in various sound environments as the day goes on. This is why they don’t last as long as watch batteries.

How can I keep from running out of hearing aid batteries?

Our audiologists recommend ordering a 30-day supply at least a month ahead of when you’ll need them, so you don’t run out. If you order 10 at a time, re-order once you’re down to 7 or 8 so shipping time isn’t a problem.

Is there any place I should or should not store my hearing aid batteries?

We suggest storing the batteries next to the place you store your hearing aid overnight. This could be in a drawer in your bedroom or in a box on your bedside table. Some people keep theirs in a drawer in the bathroom, but this is not recommended, as moisture and temperature variations can decrease battery life. They should be kept in a dry location with a consistent temperature. Never store hearing aid batteries in the refrigerator, as the temperature and moisture can ruin them quickly.
