Problem solving: batteries do not last long enough

The average life-time of a hearing aid 312 battery lies between 5 and 7 days.

Please follow these instructions to ensure long duration of your batteries:

1. Always open the battery chamber when not wearing your hearing aid.
2. In case you sweat or walk through rain, please dry the battery with a dry tissue in the evening.
3. After unpacking the battery leave it for 30 seconds in the air before placing it into the hearing aid. This launches chemical processes that are necessary for good functioning.
4. Make sure you buy the batteries at a reliable dealer. We can gladly provide you with high-class batteries in our online shop (click here).
