Rechargeable hearing aid batteries are available across most of our hearing aid families, including Beltone Imagine™ and Beltone Achieve™. Hearing aids that are not rechargeable most commonly use zinc-air disposable batteries.

Rechargeable Hearing Aid Batteries

The same type of battery that powers smartphones, tablets and laptops is now powering hearing aids. With high energy density and a small footprint, lithium-ion rechargeable batteries can deliver enough power for up to 30 hours of continuous use for some hearing aid users. Recharging your hearing aids is simple—just place the hearing aid into its charger each night, and it will be ready to go the next morning. Some models also have a quick-charge function, giving you up to eight hours of use with only 30 minutes of charging. Not yet ready to make the switch to rechargeable hearing aids?

Zinc-Air Disposable Batteries

Zinc-air batteries are not rechargeable and must be discarded after use (typically every 5-7 days). They look like small, silver buttons and come in five sizes that fit the various hearing aid styles. Because zinc-air batteries are activated by oxygen, they come factory-sealed with a sticker that must be removed before inserting them into your hearing aids. To activate the battery, remove the sticker and wait a full minute before placing it in your hearing aid. Don’t skip this step—the battery needs to absorb an adequate amount of oxygen to work properly. Once the sticker is removed, the battery is activated and cannot be resealed, so leave the sticker in place until you are ready to use the battery.

  

 

Battery Sizes

Hearing aids come in a variety of styles and sizes, so they have different battery requirements. For example, larger hearing aids or those designed for profound hearing loss use more battery power and require larger batteries. To ensure you select the correct battery size for your hearing aids, batteries come in color- and number-coded packages that make the battery size easily identifiable.

 

Store at room temperature in a dry environment.
Do not store in a bathroom or refrigerator.
Do not carry them loose in a pocket or handbag where they may touch metal items, like keys or coins. This can short-circuit the battery.

Size 5: 3-5 days
Size 10: 3-7 days
Size 312: 3-10 days
Size 13: 6-14 days
Size 675: 9-20 days

Store batteries at room temperature (65°F-80°F). Hearing aid batteries will retain up to 97% of their power for a full year when stored at room temperature.
Leave the battery compartments open when you're not wearing your hearing aids. This limits battery-drain and helps alleviate moisture build-up.
Turn off your hearing aids when not in use to help extend battery life.
Consider a hearing aid dehumidifier, which will absorb moisture from your hearing aid and battery, allowing the battery power to be used more efficiently.
Check the expiration dates and buy hearing aid batteries that don’t expire for a year or more from the purchase date.
If your batteries aren’t lasting as long as they should be, ask your hearing care
