With all the different styles and brands of hearing aids today, you might think there are an equally large variety of batteries to power them. The good news is that hearing aid manufacturers have developed a standard for all hearing aid batteries to make it as easy as possible for consumers.

While there are a few models of hearing aids that may use rechargeable or long-life batteries, the vast majority of hearing aids are powered by zinc batteries. Round button cell zinc-air batteries are the standard for all types and brands of hearing aids, whether it is behind the ear, in the canal, in the ear or any other type. The batteries come in several sizes identified by numbers and colors. That way, no matter the manufacturer of the battery, the size and color will always be the same. The most commonly used sizes and colors are:

  • 5 - red - for CICs
  • 10 - yellow - for CICs and RICs
  • 13 - orange - for BTEs and ITEs
  • 312 - brown - for mini BTEs, RICs and ITCs
  • 675 - blue - for High Power BTEs and Cochlear Implants

The batteries are activated by removing the tab and will continually provide power for about two weeks with normal use. The flat side of the battery is the positive terminal and the rounded side is the negative terminal to make it easy to insert into the hearing aid battery door.
