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

  • Kelvin connections configured to couple to terminals of the battery;

    measurement circuitry coupled to the Kelvin connections configured to measure a dynamic parameter of the battery and a voltage across terminals of the battery;

    an empirical variable input configured to receive an empirical input variable;

    computation circuitry configured to provide a relative battery test output as a function of the dynamic parameter and the empirical input variable, the relative test output indicative of a condition of the battery.
