  • Battery removal and replacement system
    Patent number: 5489485
    Abstract: A battery housing for a combination of cells which prevents inadvertent short circuiting caused by electrical contact with discarded battery assemblies. An embodiment of the battery housing comprises a conductive connector, electrically connected to the positive battery terminal, for electrically connecting to a mating contact within an appliance. A terminal insulator insulates the conductive connector from electrical contact with a second battery housing. A sleeve, comprising a length of heat-shrinkable tubing, secures the positioning of the combination of cells and the terminal insulator. A non-conductive cap insulates the conductive connector of a battery assembly removed from the appliance from any external electrical contact. An optional orientation slot is included on the terminal insulator to match with a rib incorporated within the appliance to guide a slip-in fit of the battery assembly within the appliance.
