Hearing Aid Batteries

Factors that Influence Hearing Aid Battery Life

Like with any battery, there are a number of factors that can impact the run time and life span of your hearing aid battery. These include:

• Severity of Hearing Loss - The harder the hearing aid needs to work, amplifying sound, the more it will drain the battery. Similarly, if you have to use your hearing aid for long periods of time each day, you’ll need to replace the battery more often.
• Temperature - If the battery is exposed to extreme temperatures, you’ll likely see a decline in performance and lifespan. This applies to both batteries in use and storage. Avoid exposing your hearing aid to hot or cold temperatures for extended periods of time and store unused batteries in a cool, dry place.
• Size of the Battery - As hearing aids diminish in size, the battery gets smaller too. Smaller batteries will have less "active material" inside to power your aid. These batteries may need to be changed more often.

Hearing Aid Battery Sizes and Types

Older models of hearing aids are often larger than some of the newer models. As the size of hearing aids gets smaller, the batteries used in them get smaller, too. We carry multiple battery formats that are color coded to make it easier to pick the right option each time.

How Often to Change Hearing Aid Batteries

When choosing your hearing aid battery, you also should consider the amount of time you plan to use your device each day. If you need to use your hearing aid for extended periods of time throughout every day, your battery may need to be replaced more often. The type of hearing aid you use and the severity of your hearing loss can also play a part in how frequently you need to change your hearing aid batteries.

The expected lifespan of your battery will likely vary based on the above factors. Some types of batteries for hearing aids need to be changed every 5 to 7 days, while other types have a lifespan that can last up to around 10 days.

Ingestion Safety Warning

Due to their small size, hearing aid batteries are incredibly easy to swallow, especially for children. While these batteries are safe for normal use, they can be hazardous when ingested. To avoid accidental ingestion, do not leave your batteries within reach of children. For more information, read our ingestion safety tips.
