Hearing Aid Batteries

Understanding Hearing Aid Battery Sizes

Hearing aid batteries come in standardized sizes, typically identified by color codes and numbers: 10 (yellow), 13 (orange), 312 (brown), and 675 (blue). Choosing the correct hearing aid battery size is essential for compatibility with your device.

Always check your hearing aid's manual or the old battery for the correct size and color code.

Zinc-Air Hearing Aid Battery Technology

Most modern hearing aid batteries are zinc-air batteries, which are activated by exposure to air. Once the tab is removed, oxygen reacts with the zinc inside, generating power. These zinc-air batteries offer a stable voltage and long shelf life when sealed.

It's important to wait a few minutes after removing the tab before inserting the battery into your device for optimal activation.

Maximizing Your Hearing Aid Battery Life

To get the most out of your hearing aid batteries, store them in a cool, dry place and keep the protective tab on until ready to use. Turn off your hearing aid or open the battery door when not in use overnight to conserve power.

Avoid storing batteries in humid environments like bathrooms, as moisture can impact their performance and lifespan.
