Hearing aids come in a set of common sizes. With a limited selection of cell size, your device will probably need one of four common sizes. Because you rely on your device for daily communication and interaction, the team at Imagine Hearing Solutions offers the most common hearing aid batteries and accessories. Let’s direct you through the most popular battery sizes of hearing aids and explain what cells are compatible with what types of hearing aids.

Types of batteries

In the disposable category there are four total sizes of battery, each with its own advantages and disadvantages. The most common are zinc-air batteries. When power is depleted, they should be discarded just like any other disposable battery. The batteries are activated by oxygen, which is triggered by removing the tab on each battery. It’s important to wait a few minutes after removal for best performance.

Here are the colors and corresponding numbers for each battery type:

Blue (#675): As the largest battery, the blue type has the longest runtime of all the batteries (300 hours). Due to the size, only the behind-the-ear (BTE) style can leverage its power.
Orange (#13): We use these in larger styles like BTE and in-the-ear (ITE) devices. As one of the larger batteries, they last up to 240 hours.
Brown (#312): These are one of the smallest types, so they are only suitable for the in-the-canal (ITC) and completely-in-canal (CIC) devices. They last about 175 hours.
Yellow (#10): This is the smallest type and lasts for about 80 hours before needing to be replaced.

How to extend the life of your batteries?

When activating the battery, wait about five minutes before putting it into battery compartment. Studies have shown that this can improve battery life by as much as 80%. Also, try to keep your batteries at a consistent temperature, as temperature fluctuations can affect battery performance. Opening the battery gate when the hearing aid is not in use and storing the device in a cool, dry place are other easy ways to maintain battery life.

When it’s time to change your battery, a related app or a continuous beeping noise from the device will notify you. Because usage patterns vary among hearing aid users, batteries can run out at any point, so you should always be prepared with spares that are close to hand.
