1. An electronic battery tester, comprising:

  • test circuitry configured to couple to a battery and measure a parameter of the battery;

    a manual input configured to receive an input from an operator;

    a user output configured to provide an output to the operator;

    a memory containing programming code, the programming code including programming code to output on the user output battery test procedure instructions for implementation by the operator wherein the output battery test procedure instructions differ based upon the battery being tested, the memory further containing measurement information and test criteria; and

    a microprocessor which operates in accordance with the programming code to instruct the operator to perform the battery test procedure and perform a battery test based upon the measured parameter, the measurement information and the test criteria;

    wherein the battery test procedure output by the microprocessor changes as a function of the battery being tested to instruct the operator to perform different steps in the battery test procedure based upon the battery being tested,wherein the microprocessor is further configured to, upon receiving an instruction-selection-enabling input, operate in accordance with the programming code to output on the user output a portion of the battery test procedure instructions specific to the battery being tested, and configured to test the battery according to one or more test-step-advancing inputs, related to the battery being tested, received by the microprocessor in response to the portion of the battery test procedure instructions output on the user output, andwherein at least one of the one or more test-step-advancing inputs, related to the battery being tested, received by the microprocessor in response to the portion of the battery test procedure instructions output on the user output is different from the measured parameter, the measurement information contained in the memory and the test criteria contained in the memory, and wherein the at least one of the one or more test-step-advancing inputs related to the battery being tested comprises a sensed voltage.
