How often will I need to replace my hearing aid batteries?

On average, hearing aid batteries need to be replaced approximately every 5-7 days. Some factors that may affect the life of the battery include:

Size of the battery: There are different sizes of hearing aid batteries which depend on your hearing aid. The larger the battery, the longer it is likely to last. The most common battery size is 312/brown sticker pack.

Activation time: Hearing aid batteries are air activated once the tab is removed. The battery will be fully activated approximately 1-2 minutes after removing the tab and before inserting into the hearing aid. Even if you don’t us the battery it will start to deteriorate over time.

Advanced features: Some hearing aids have advanced features, such as wireless streaming for phone calls or music, which require more energy from the battery.

To eliminate the hassle of changing hearing aid batteries every week, rechargeable hearing aids are a popular option. Rechargeable hearing aids sit in a charger overnight and will last up to 30 hours of use on a full charge.

For more information on the convenience of rechargeable hearing aids, call Gardner Audiology at 1-800-277-1182 or email to schedule a hearing aid consultation with one of our Board-Certified Audiologists.
