These Longlife Extra hearing aid batteries from our 123ink 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 lasts for a long time.
These 312 hearing aid batteries have a zinc-air composition. As the name suggests, this compound relies on air for operation. It is therefore important to leave the seal (the brown tab) in place until you intend to use the battery.
Once 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 60 batteries.
Of course this 123ink product also comes with a 100% warranty!
