Hearing Aid Batteries – Dr. Emily McMahan

Your hearing aids need a steady power supply from high quality hearing aid batteries in order to run effectively. Even subtle changes in a batteries output can mean the difference between clear performance and poor volume or noise control.

Alaska Audiologist Dr. Emily McMahan stocks batteries for all major hearing aid manufacturers. If you are unable to control the levels in your hearing aid it may be that your hearing aid batteries are low and need to be replaced. Below are some FAQ’s about hearing aid batteries.

How long do batteries typically last?

Standard hearing aid batteries lasts anywhere from 3 to 22 days, depending on the hearing aid type, battery type and capacity, and the amount of hearing aid use.

How do I know if I should change my hearing aid batteries?

  • Change your hearing aid batteries if sounds become distorted or you have to turn up the volume more than usual.
  • Some hearing aids will also make a small beeping sound when the battery is low. Be sure to switch your hearing aid batteries immediately when you hear the alarm.
  • Hearing aid batteries often lose power very suddenly, so it’s smart to carry an extra set of batteries with you at all times.
  • To protect against discharging your backup batteries, keep them away from coins, keys or other metal objects.


What’s with the seal on hearing aid batteries?

Always purchase unopened battery packages. Make sure the seal on a new battery is unbroken. Hearing aid batteries begins to discharge as soon as the protective seal has been removed.

  • If you won’t be using the hearing aid for an extended period of time, remove the battery entirely.
  • Avoid storing in extreme temperatures to keep from draining battery power and shortening battery life.


What are some good care tips for hearing aid batteries?

  • Store hearing aid batteries at normal room temperatures.
  • Do not refrigerate.
  • Wash your hands thoroughly before changing batteries. Grease and dirt on the batteries may damage the hearing aid.
  • Leave the battery compartment of your hearing device open at night so moisture can escape. Doing so will keep the battery from corroding and damaging the hearing aid.
  • Remove dead hearing aid batteries immediately. A completely discharged battery may swell and become difficult to remove.
