What kinds of batteries do hearing aids use?

Most hearing aids use disposable zinc-air batteries 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 your audiologist at ENT Specialists of Metairie or ordered online.

How long will hearing aid batteries last?

On average, batteries last five to seven days depending on the size and style of your hearing aids, your degree of hearing loss, the amount of time your hearing aids are used and your listening environment.

How will I know when it’s time to change the batteries?

Obviously if there is no sound coming through your hearing aids, your first suspicion should be a dead battery. Other signs include sound that is distorted or unclear and unusually low volume levels. Some hearing aids are designed to produce an audible tone warning you when batteries are low.
