1. A method comprising:

  • obtaining a plurality of batteries;

    obtaining information related to each of the plurality of batteries;

    performing at least one battery test on each of the plurality of batteries to obtain at least one test result for each of the plurality of batteries;

    associating the at least one test result for each of the plurality of batteries with the corresponding obtained information related to each of the plurality of batteries;

    generating a reference value based upon the test results obtained for the plurality of batteries, the reference value is for a specific battery model to which the plurality of batteries belong;

    storing the reference value and a battery model code associated with the reference value in a memory;

    performing a battery test on another battery, which is not one of the plurality of batteries, but of a same model as each of the plurality of batteries; and

    providing a battery test output based on a comparison of measurements obtained, during the battery test on the battery that is not one of the plurality of batteries, with the reference value,wherein the test results for the plurality of batteries comprise dynamic parameter values, andwherein the reference value is an average of the dynamic parameter values that fall within a predetermined range of acceptable values, with the dynamic parameter values that fall outside the predetermined range of acceptable values being excluded.
