How long can I store my batteries? Do they discharge themselves at some point?

All of today's hearing aid batteries work on the basis of zinc and oxygen. That is why you will always find a colored sticker on one side of the hearing aid battery.

This sticker keeps the battery close to airtight. As soon as you remove this sticker, the zinc/air battery is activated by drawing in oxygen through tiny holes. Therefore, you should not remove the sticker until you need the battery.

It is recommended that you remove the sticker from the battery, and wait about 2 minutes, before you insert the battery. If you need immediate assistance, you can call us at 1800 480 480 or 01 874 2341.
