1. An electronic battery tester for testing a storage battery comprising:

  • a Kelvin connection configured to electrically couple to the storage battery;

    a microprocessor configured to determine a dynamic parameter of the storage battery;

    a data bus coupled to the microprocessor configured to carry data in the electronic battery tester;

    a connector coupled to the data bus and configured to communicate with a spaced apart digital module, the connector including electrical connections which couple to the data bus;

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

    a sensor electrically coupled to the storage battery and configured to sense an electrical response of the storage battery to the applied forcing function signal; and

    wherein the microprocessor is configured to couple to the spaced apart digital module and send or receive data from the spaced apart digital module on the data bus.
