    I have several out of date – expired- battery packs. Does the use of these in any way damage the hearing aid?

      Thank you for reaching out to us. We caution the use of expired batteries as the battery life may be reduced as well as the possible threat of the battery corroding and damaging the hearing device. We recommend only using batteries that have not expired.

      Hi Vicki,

      If you are looking at them side by side, the rechargeable battery is MUCH more shiny, and it has writing on the back along with the + sign. The regular battery is much more dull/matte, and instead of writing near the + sign, there are 3 very tiny holes. We hope that helps!
