Without batteries, your hearing aids would be unable to function. Batteries can either be disposable or rechargeable. Most disposable batteries are zinc-air that are color- and number-coded for easy replacement. The type of battery needed depends on the style and size of your hearing aids and includes: 10 (yellow), 13 (orange), 312 (brown) and 675 (blue).
Most drugstores carry replacement batteries; they can also be purchased from Watauga Hearing or ordered online.
