Abstract
An electronic battery tester for testing a storage battery while the storage battery is coupled to a wiring system includes a first electrical probe configured to physically and electrically couple to a positive terminal of the storage battery, a second electrical probe configured to physically and 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 at a physically remote location from the storage battery, and a fourth electrical probe configured to electrically couple to the negative terminal of the storage battery at a physically remote location from the storage battery. Battery test circuitry couples to the first, second, third and fourth probes and performs a battery test on the storage battery using the first, second, third and fourth probes in a Kelvin connection configuration and responsively provides a battery test output.
