ABSTRACT:
A protective device for a repeatedly rechargeable electrochemical battery (10) with a battery housing (12), the protective device having at least one switching element (86) which can be activated by a detector element (62) and which is designed or adjusted to prevent recharging and/or discharging of the battery (10) in an impermissible operating state thereof. The protective device has a hermetically sealed protective housing (54) which holds the battery housing (12). An impermissible operating state of the battery (10) causes a change in shape (deflection) to be impressed on the detector element (62). Preferably, the at least one switching element (86) is made as a make contact which electrically short circuits a recharging circuit supplied by a charging device when a predetermined expansion in the volume of the battery housing (12) and/or gas escape therefrom occurs. The protective device is part of an implantable device, such as a hearing aid.
