Hearing Aid Batteries

Hearing aid batteries aren’t that much different than there were a few years ago. The technology has made strides in the direction of stability, although there has been an innovation or two in other areas. Hearing aid batteries remain rock solid for extended use even with extra features like Bluetooth being active. The Hearing Aid Specialists of the Carolinas covers battery information during the fitting. Brand, type and maintenance are all discussed with the patient.  

Battery types

Hearing device brands will always use batteries that work best with a particular series. It isn’t uncommon to see a hearing aid manufacturer using three or four different types of batteries across their entire catalog of devices. There are four total sizes in the disposable category, each with their own set of strengths and weaknesses. Zinc-air batteries are the most common, but are not rechargeable. They should be discarded when depleted of power. The batteries are not activated until the tab is removed and oxygen molecules hit it. This is why it’s important to wait 1-2 minutes before adding it to the hearing aid

  • Orange (#13) – Used for Behind-The-Ear and In-The-Ear devices. Lasts up to 240 hours on a single use
  • Brown (#312) – The smallest battery so its main purpose is for In-The-Canal and Completely-In-Canal devices. Lasts about 175 hours
  • Yellow (#10) – In-The-Canal and Completely-In-Canal devices also use yellow. This battery lasts for 80 hours before needing a replacement
  • Blue (#675) – Blue has the longest runtime of all the batteries with up to 300 hours total. It’s used in the bigger hearing aid options like Behind-The-Ear

Extending the life of batteries

Buying hearing aid batteries is easy if users follow the color codes. Usage patterns of the individual will determine when the battery needs to be changed. A blue may last one person a few weeks, yet someone else with the same battery will need to change every few days. One of the best ways to preserve battery life is by opening the battery door when the hearing aid is not in use. Storing in a cool and dry place is another way to extend the life of a battery. When it is time to make a change, users will be notified by an associated app or by a constant beeping noise from the device. Since usage patterns are never the same, users should always have extra batteries ready.
