How to get the most out of your rechargeable batteries
Please make sure that both batteries are used on a regular basis.
Constantly recharging the batteries will shorten their service life.
That's why you should exchange the batteries in the hearing aid
with the batteries in the charging station regularly (for best results,
once a week).
