1. An electronic battery tester for use in testing a battery pack formed by a plurality of storage batteries, comprising:

  • battery test circuitry configured to measure a dynamic parameter of the battery pack formed by the plurality of batteries using Kelvin connectors coupled to the battery pack and provide a battery test result;

    a memory configured to store a plurality of known configurations (series, parallel and series-parallel) of batteries in a battery pack;

    a microprocessor configured to automatically identify the configuration (series, parallel and series-parallel) of the plurality of batteries in the battery pack based upon a measured voltage of the battery pack and responsively change a test criteria of the battery test circuitry; and

    wherein the battery test result is based upon the identified configuration of the plurality of batteries.
