Hearing Aid Batteries

Hearing aid technology may change, but the need to power hearing aids stays the same. All hearing aids require a source of power. Whether your hearing aids use rechargeable or disposable batteries, Valley Hearing Center has the batteries you need.

Disposable hearing aid batteries

Disposable hearing aid batteries use zinc-air technology. The zinc ions in the battery create an electrical charge when they are exposed to the oxygen that’s in the air around us. This style of battery lasts about every 7 to 10 days. Many hearing aids emit a beeping sound when the battery level is low. If your digital hearing aids have a smartphone app, the app may monitor your battery levels.

Buying disposable hearing aid batteries

Shopping for hearing aid batteries is easy. While there are many hearing aid manufacturers, there are only a few hearing aid battery sizes. Each battery size is color-coded and assigned a number for quick identification. Valley Hearing Center carries hearing aid battery sizes as follows:

  • Orange (#13): In-the-ear (ITE) and behind-the-ear (BTE) hearing aids generally use orange batteries. Average life is about 240 hours. 
  • Yellow (#10): In-the-canal (ITC) hearing aids generally use the yellow battery. These batteries provide about 80 hours of use.
  • Blue (#675): The blue battery is the largest battery and it is used in the largest hearing aids, like a BTE or some ITE models . This battery lasts the longest and provides about 300 hours of use.
  • Brown (#312): The smallest hearing aids are worn deep in the ear canal and use the smallest battery. The brown battery lasts about 175 hours.

Rechargeable hearing aid batteries

If you live an active lifestyle, travel frequently or have vision or dexterity issues, then hearing aids powered by rechargeable batteries may be the best option for you. You won’t need to worry about keeping a supply of fresh batteries with you and won’t need to fumble or squint when faced with tiny, button-sized batteries and small battery doors.

Most rechargeable batteries use lithium-ion technology and may need recharging every few days or daily, depending on the battery. These batteries recharge, much like the battery in your smartphone. Hearing aids with rechargeable batteries come with a docking or charging station.

During your hearing evaluation, the hearing health specialist will discuss your needs to match you with the right hearing aid and the right style battery. During your fitting appointment, Valley Hearing Center will teach you how to replace or charge your hearing aid batteries.
