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:
- Always open the battery chamber when not wearing your hearing aid.
- In case you sweat or walk through rain, please dry the battery with a dry tissue in the evening.
- 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.
- 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).
