1. A battery diagnostic system, comprising:

  • Kelvin connectors configured to electrically couple to a storage battery;

    a forcing function source configured to a forcing function signal to the storage battery through the Kelvin connectors;

    measurement circuitry calculating an electrical parameter of the storage battery;

    a memory storing a plurality of electrical parameters for each of a plurality of storage batteries, each of the plurality of stored electrical parameters associated with storage battery identification information which identifies one of the plurality of storage batteries and time information, which identifies a time the electrical parameter was obtained;

    diagnostic circuitry coupled to the memory and diagnosing a condition of the storage battery based upon the calculated electrical parameter of the storage battery, the plurality of stored electrical parameters for the plurality of storage batteries, the identification information and the time information;

    wherein the diagnostic circuitry identifies a peak value of the plurality of stored electrical parameters; and

    wherein the peak electrical parameter is used as a baseline and diagnostic output from the diagnostic circuitry is based upon a comparison of a current measured electrical parameter to the baseline.
