Battery life varies depending on factors such as battery size, type of device, and usage. Typically, disposable hearing device batteries last anywhere from 3 to 10 days, while rechargeable batteries can last a full day or longer on a single charge.

There are two main types of device batteries: disposable zinc-air and rechargeable lithium-ion. Disposable batteries come in various sizes, denoted by color-coded labels, such as size 10 (yellow), size 312 (brown), size 13 (orange), and size 675 (blue).

Most devices play a warning signal, such as a beep or tone, when the battery is low. Also, you may notice a decrease in hearing aid performance, such as reduced volume or distorted sound, which indicates it’s time to replace the batteries.

Store hearing device batteries at room temperature in a dry environment. Avoid exposing them to extreme temperatures or humidity, as this can affect their performance and lifespan. Keep batteries away from metal objects, such as coins or keys, to prevent short-circuiting.

Yes, hearing aid batteries are recyclable. Many local recycling programs accept hearing device batteries, or you can drop them off at designated recycling centers. Some hearing clinics and battery retailers also offer battery recycling services.
