1. A device for testing a battery, comprising:

  • measurement circuitry adapted to apply a signal to cells of the battery and measure a response signal of the cells that make up the battery; and

    a microprocessor coupled to the measurement circuitry adapted to determine a statistical parameter of a first portion of a string of cells that make up the battery as a function of the response signal, measure a first dynamic parameter of a second portion of the string of cells that make up the battery as a function of the response signal, and provide an output based upon a comparison of the statistical parameter to the dynamic parameter.
