ABSTRACT:
A differential voltage battery DC power supply for use with an electronic device, such as a computer, comprising a multi-cell battery, a plurality of regulators, at least one filter and a recharging circuit. The battery cells are electrically interconnected serially to produce positive voltages of 0 to positive 12 volts DC and negative voltages of 0 to negative 12 volts DC. The battery includes output terminals having output DC voltages closely corresponding to the input DC voltages required to power the electronic device. The output terminals are electrically interconnected to regulator circuitry, structured to drop the corresponding battery output terminal DC voltages to the input DC voltages required by the electronic device, and filters, structured to remove unwanted transients. The recharging circuit includes an AC voltage input terminal, at least one transformer structured to drop the input AC voltage to AC voltages corresponding to the battery output terminal DC voltages, and a plurality of rectifiers structured to convert the output AC voltages from the transformers to positive and negative DC voltages corresponding to the battery output terminal DC voltages.
