1. A car battery jumper cable apparatus having a first positive pole and a first negative pole to be fitted to an exhausted car battery and a second positive pole and a second negative pole to be fitted to a supplementary power source battery, wherein the apparatus comprises:

  • a relay comprising an exciter coil and a switch, wherein the switch is coupled between the pole of the exhausted car battery and the pole of the supplementary battery;

    a relay driving circuit coupling to the exciter coil of the relay for controlling whether current flows to the exciter coil of the relay;

    a battery polarity recognition circuit coupling between the pole of the exhausted car battery and the pole of the supplementary battery for examining whether the pole of the exhausted car battery is correctly connected to the pole of the supplementary battery, and wherein an output terminal of the battery polarity recognition circuit is coupled to the relay driving circuit to control whether the relay is excited;

    a signal oscillator wherein an oscillation-enabled terminal is coupled between the pole of the exhausted car battery and the pole of the supplementary battery by a current detector to examine an immediate recharged current status, and wherein an output terminal is coupled to the battery polarity recognition circuit to determine whether to output an oscillation pulse wave signal to the battery polarity recognition circuit along with-the recharged current status;

    an alarm circuit of reverse battery polarity coupling between the pole of the exhausted car battery and the pole of the supplementary battery, wherein a warning sounds when the coupled battery polarity of any end of a cable is reversed in relation to a required fitting;

    an indicator light for discharged battery connection comprising a first light-emitting diode, wherein an anode and a cathode of the first light-emitting diode are coupled to the positive pole and negative pole of the exhausted car battery respectively; and

    an indicator light for recharged battery connection comprising a second light-emitting diode, wherein an anode and a cathode of the second light-emitting diode are coupled to the positive pole and negative pole of the exhausted car battery.
