Common Battery Sizes

Common battery sizes are 10, 13, 312, and 675. To identify the battery size, manufacturers use an industry standard colour coded system.

Size 10: Yellow

Size 13: Orange

Size 312: Brown

Battery life is affected by several factors such as: size of batteries, hearing aid model, how long you use the hearing aid, the volume setting and even the background noise.
