ABSTRACT:
A battery jumper cable with a polarity indicator is disclosed which includes a positive power and negative power connecting wire, the two ends of which are respectively disposed between donor battery end clips and depleted battery end clips for clipping the terminals of the donor and depleted batteries; and a polarity indicator including a donor battery indicating means, a depleted battery indicating means, and an override protective means. The override protective means is disposed between the clips of the positive and negative battery connecting wires. The donor and depleted battery end indicating means includes light emitting diodes positively connected between the positive and negative battery connecting wires, respectively, near the donor and depleted battery ends. When the connections to the donor and depleted battery ends are correct, the light emitting diodes are energized to emit light to indicate the correct connection. A buzzer is negatively connected in parallel between the positive and negative battery connecting wires for emitting a warning sound when the wires are incorrectly connected. When an incorrect connection causes a short circuit, the override protective means is able to disconnect the wires to prevent damage to the circuit.
