The power source of BTE (Behind the Ear) hearing instruments is an internal battery which has to be covered or just held at its designated place by a battery compartment cover. Up to now, such covers are mainly made of solid plastics. These parts do not protect the battery compartment from moisture penetration sufficiently and also are susceptible to battery door hinge breaking.
