Since hearing aids are electronic devices, their operability depends on a power source. Up to now, BTE (behind the ear) hearing aids with rechargeable power storages (i.e. batteries) use an external contact point for that functionality. With this external contact point, the hearing aid user is exposed to the battery and although the voltage is relatively small, some countries prohibit such constructions. Thus, most rechargeable BTE models need to be redesigned without the recharge functionality. Besides, the use of external contacts can itself be problematic because of the pin-to-hole alignment or protruding pins that are not aesthetically accepted.
