  • Patent number: 7498770
    Abstract: A load controlled battery charging device is provided which is structured to apply an electrical charge to a plurality of rechargeable storage batteries having a wide range of voltage output capacities. The device includes an electrical charging circuit having an input connection to a power source to provide the power required to permit recharging the batteries. The load controlled charging device also includes a load bank structured to draw a substantially constant electrical current from the power input, and may include a rectifier to convert an alternating current power supply to a direct current to be applied to the rechargeable storage batteries. Additionally, the load controlled battery charging device includes a charging current output connection structured to interconnect the electrical charging circuit to the rechargeable storage battery, at least during the charging operation.
