1. An electronic battery tester for testing a storage battery, comprising:

  • a first pair of connectors configured to couple to a positive terminal of the battery;

    a second pair of connectors configured to couple to a negative terminal of the battery, the first and second pairs of connectors forming a Kelvin connection with the battery;

    a memory;

    a calibration interface configured to provide a calibrator control output to a calibrator;

    a microprocessor configured to test the battery through the Kelvin connection based upon a calibration value stored in the memory, the microprocessor further configured to communicate with the calibrator through the calibration interface to initiate a self calibration, measure a calibrated value of the calibrator through the Kelvin connection and store the measured calibrator value in memory as the calibration value.
