These Longlife Extra hearing aid batteries from our 123accu house brand are of high quality and suitable for in-the-ear (ITE) hearing aids that use battery type 312 (brown). The batteries have an extra large capacity and ensure that your hearing aid will last for a long time.

These 312 hearing aid batteries have a zinc-air composition. As the name suggests, this composition depends on air for its operation. It is therefore important to leave the seal (the brown tab) in place until you plan to use the battery. As soon as you want to use the battery, we recommend that you wait 2 minutes

after removing the seal before inserting the battery into the hearing aid. This gives the battery the opportunity to activate. The package contains 6 batteries.
