1. An apparatus for calibrating an electronic battery tester, the battery tester of the type having first and second battery tester Kelvin connections configured to couple to terminals of a battery, the apparatus comprising:

  • a first Kelvin connection having an A′

    terminal and a C′

    terminal configured to couple to the first battery tester Kelvin connection;

    a second Kelvin connection having a B′

    terminal and a D′

    terminal configured to couple to the second battery tester Kelvin connection;

    a calibrated shunt in series with a power supply connected between the A′

    terminal of the first Kelvin connection and the B′

    terminal of the second Kelvin connection, the calibrated shunt having a calibrated resistance value; and

    an active shunt in series connected between the C′

    terminal of the first Kelvin connection and the D′

    terminal of the second Kelvin connection, the active shunt providing a calibrated apparent resistance between the C′ and

    D′

    terminals which is a function of the calibrated resistance value of the calibrated shunt.
