Hearing Aid Batteries

When choosing the perfect hearing aid, one thing you need to consider is your hearing aid batteries.

Smaller batteries can be used in smaller hearing aids, and if discretion is your main concern, you’ll use a smaller battery. However, if you have severe hearing loss, or need a hearing aid that packs a lot of punch, you might consider a hearing aid that accommodates a larger battery.

Hearing Aid Battery Sizes

size 675 battery

675: Batteries with a blue label are size 675, and they are the most powerful batteries on the market. These batteries are normally fitted into Behind the Ear devices, provide a lot of power, and can last longer than some of the smaller batteries.

Size 13 battery

13: Size 13 batteries come with an orange label, and they are the second most powerful battery you can find. You’ll find size 13 batteries in most In the Ear hearing aids.

size 312 battery

312: With a brown label, size 312 is the most common battery size. They have a moderate battery life, lasting for a few days, and still provide enough power for all the programs and features you love. They are found in In the Canal and Receiver in the Ear devices.

size 10 battery

10:  The smallest hearing aid batteries are size 10, and they have a yellow label. While they have a short battery life, and you’ll have to replace them more often, these batteries can easily fit into tiny devices, like Completely in the Canal devices.

Battery Life

How long your battery lasts will depend on a few variables, including the battery size, the number of hours per day you use your hearing devices, and the power output needed by the programs you are running. If you spend your days in a noisy environment with a background noise suppression program activated, you’ll use more power than if you spend the day in the quiet of your living room. On average, hearing aid batteries will last anywhere from 3 to 10 days.

Getting More Out of Your Batteries

When using hearing aid batteries, it’s important to realize that the advanced programs and features you’re using will drain your batteries throughout the day. Unlike the batteries in your alarm clock that use a very small amount of power, hearing aid batteries power your entire hearing aids for many hours each and every day.

One way to get more out of your batteries is to open the battery doors at night, or whenever you take your devices out of your ears. This ensures that the hearing aid batteries and contact posts dry out every night, improving function and extending the battery life.

Storing Hearing Aid Batteries

The best place to store your hearing aid batteries is in a safe and dry place, like on your bedside table or in your desk drawer. While you might think the bathroom would be the best place for your hearing aids and batteries, the higher humidity in the bathroom could be damaging your devices and your batteries. Keep all your batteries in the same place, along with your cleaning kit, carrying case, or any other hearing aid products you have. Store your hearing aids and batteries away from direct sunlight, and never put them in the fridge. Your batteries should always be stored at room temperature, and in a dry place.

It’s also a good idea to keep a spare set of batteries in your bag or in your wallet so that if you run out of power during the day you won’t have to struggle through the rest of your day, or make an emergency trip back home.

How to Change a Hearing Aid Battery

Changing hearing aid batteries is quick and easy, and just requires a few simple steps. First, take off the tab on the battery. You should never remove the tabs before you need to use the batteries, as this will oxygenate the battery, and start draining power. After removing the tab, insert the battery into the hearing aid with the positive (+) sign facing up.
