How Long Do Hearing Aid Batteries Last?

This blog post has been reviewed and approved by a hearing care professional.

Batteries are essential to keeping your hearing aids performing at their best. The time that your hearing aid batteries last will depend on a variety of factors. Things like the type of battery used, the hearing aid model, if you stream audio with your hearing aids, and how long the hearing aid is used for all matter. Here is how long each type of battery lasts with an average wear time of 12 hours and no direct streaming:

  • One size 10 battery - 3 to 5 days

  • One size 312 battery - 7 to 10 days

  • One size 13 battery - 10 to 14 days

  • One size 675 battery - up to 3 weeks

Most batteries have a “shelf-life” of about three years, if stored properly. All batteries will have an expiry date on their box. If you need more batteries or know what size batteries your hearing aids use, you can contact your local hearing healthcare professional.
How do I know if my hearing aid batteries need changing?

You likely need to change the batteries in your hearing aids about once a week, depending on how often you use them and what size batteries they are. You should change your hearing aid batteries if:

  • The low-battery indicator or voice alert comes on

  • Sound becomes distorted

  • You have to turn up the volume more than normal

If you change the battery and continue to experience sound distortion or the need to increase the volume please contact your hearing clinic to investigate further.
Hearing Aid Battery Care Tips

If you want to know how to care for your hearing aid batteries so they last as long as possible, you can try the following: 

  • Store hearing aid batteries at room temperature

  • Do not refrigerate them, the cold reduces their shelf life

  • Remove the sticker around the batteries only when you are ready to use them. 

  • Allow the batteries to ‘charge up’ for a full 30 seconds prior to closing your battery door

  • Wash your hands thoroughly before changing batteries

  • Leave the battery door of your hearing aid open at night to turn the device off and so moisture can escape

  • Remove dead batteries from your hearing aids immediately

  • Hearing aid batteries often lose power very suddenly, so it's smart to carry an extra set of batteries with you at all times

Rechargeable Hearing Aids

How long your hearing aid batteries will last will depend on the type of batteries you require. It can vary from three days to three weeks with them having a “shelf-life” of around three years.
