1. A method of testing a storage battery, comprising:

  • (a) measuring a dynamic parameter of the battery;

    (b) obtaining an open circuit voltage of the battery; and

    (c) measuring a temperature of the battery;

    (d) obtaining a cranking size rating of the battery; and

    (e) estimating a load test voltage of the battery as a function of the measured battery dynamic parameter, the open circuit voltage of the battery, the measured battery temperature and the cranking size rating of the battery, the estimated load test voltage indicative of power remaining in the battery.
