OSTI ID:6766270
A rechargeable battery includes a storage cell, a housing enclosing the storage cell, a rectifier in the housing, and a pair of output terminals exposed for delivering electrical energy from the storage cell. The battery is provided with a pair of prongs arranged for electrical connection to a female power supply receptacle. The prongs are pivotally mounted at opposite sides of one of the terminals to extend selectively in a first disposition straddling one end of the housing, and a second disposition projecting from that one end in parallel-spaced relationship to be received in the female power receptacle. The electrical circuit of the rechargeable battery includes a switch for electrically connecting the prongs to the rectifier and storage cell to permit recharging of the storage cell from the female power supply receptacle only when the prongs are disposed in the extended disposition. The prongs may be biased both to the retracted disposition and the extended disposition, and at least one of the contacts may be a spring contact for effectively maintaining electrical connection between the prongs and the charging circuitry. One of the contacts of the switches may be defined by a portion of the prongs. 6 figures.
