Do Hearing Aid Batteries Expire?

As with all batteries, hearing aid batteries do expire. The average hearing aid battery has a shelf life that lasts about four years. When buying hearing aid batteries, always check the end date on the package. It is a good idea to stock up to have enough to meet your needs for a few months. But, too large of a stockpile can lead to waste. Avoid wasting hearing aid batteries by not using them before they expire. Always use the closest end date first.

Many Factors Impact Battery Lifespan

Once the battery is in and starts working, many things can affect how long the battery lasts. Smaller batteries have shorter lifespans. They last about 3 to 10 days. Some of the larger ones can last 9 to 20 days.

High tech hearing aids use more power from the battery. The degree of hearing loss can also affect the battery’s shelf life. The higher the amplification of sound needed, the more energy the hearing aid uses.

Your environment can also affect the hearing aid battery lifespan. With a lot of background noise, your hearing aid may use more power. This will decrease the battery faster. Extreme temperatures, humidity, and altitude can also affect battery life.

Store The Battery Better For Longer Shelf Life

You should keep batteries in the package or a battery caddy until ready to use. Once the tab comes off, and you expose them to air, the battery is then activated. Store them in a dry, room temperature area. Humid places, like a bathroom cabinet can shorten the life of the battery. Cold places, like the refrigerator, can also shorten battery life.

How You Can Make Your Hearing Aid Batteries Last

Battery life length can be hard to predict with so many factors at play. There are things you can do to extend battery life. Hearing aid batteries are zinc-air powered. Following the installation instructions is important to battery performance and lifespan. After removing the tab from a new hearing aid battery, wait two to five minutes before installing it. This gives it time to power up.

When you take your hearing aid out for the night, turn it off. Leave the battery slot door open to let any extra moisture out. Keep your hearing aid clean. Avoid getting lotion, perfume, and other substances on your hearing aid. This action will protect function and battery life.
