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.
