Hearing Aid Batteries

All hearing aids require hearing aid batteries to power the unit. Most modern hearing aids don’t come with a rechargeable battery. So hearing aids often require regular batteries for use. These batteries require changing between 5 days to two weeks of use.

Every model of hearing aid requires a different type of battery, due to different sizing and power needs. Larger and more power hearing aids often require more powerful hearing aid batteries. While smaller hearing aids require less power and therefore you can use a smaller battery.

The most common sizes of batteries, used for the majority of hearing aids, are sizes 10, 13, 312 and 675.

Luckily the industry has a standard colour scheme across all brands to ensure that it’s easy for you to pick the right size.

While hearing aid batteries normally last on average 5 - 7 days, if you find that you device is dying sooner, then it’s best to take them back to get them checked. Turning your hearing aid off when not in use can also increase their lifespan.

There are also other factors that can affect the lifespan of your hearing aid batteries. Humidity and heat exposure can definitely reduce the lifespan of the battery. Temperatures at around 21 c (room temperature) are the optimal temperature for long-term lifespans. The lifespan of most zinc-air batteries is around 3 years.

Additionally, keeping your batteries in a purse with other metal items may also short-circuit and reduce their lifespan.

When not using your hearing aid the best thing to do is to remove the batteries as well as open the battery compartment door to help any excess moisture escape from the compartment.

Most manufacturers now make mercury-free hearing aid batteries which perform on par with products that have traditionally been made with mercury, in order to assist with internal conductivity.

The mercury-free products will indicate so on the package. A few companies do not include mercury in their batteries based on legislative decisions. Some people feel more at peace with mercury-free hearing aid batteries so companies, and us at Ozen, have provided several mercury-free options.
