1. An electronic battery tester for testing a storage battery while the storage battery is coupled to an electrical wiring system, comprising:

  • a first electrical probe configured to electrically couple to a positive terminal of the storage battery;

    a second electrical probe configured to electrically couple to a negative terminal of the storage battery;

    a third electrical probe configured to electrically couple to the positive terminal of the storage battery;

    a fourth electrical probe configured to electrically couple to the negative terminal of the storage battery;

    battery test circuitry coupled to the first, second, third and fourth probes and configured to perform a battery test on the storage battery as a function of a current through the first and second probes and as a function of a voltage between the third and fourth probes and responsively provide a battery test output;

    wherein at least one of the probes is adapted to electrically couple to the battery at a physically remote location from the storage battery.
