Abstract
A set of battery jumper cables for placing a discharged battery parallel with a charged battery in order to increase the amount of electrical energy available to the discharged battery. The battery jumper cables include a pair of conductor cables having at each end disengagable clamp handles for coupling terminals of the charged and discharged batteries. One of the conductor cables includes a half wave rectifier biased to permit an electrical charging current from the positive terminal of the charged battery, but prevent reverse flow and potential damage to automobile computer circuitry. In a preferred embodiment the half wave rectifier is replaceably included in one of the disengagable clamp handles of one of the conductor cables. Alternative embodiments include color coding the conductor cables. Other embodiments also include indicia on a clamp handle indicating the bias of the half wave rectifier.
