Abstract
A method and apparatus for testing a storage battery is provided in which a battery is measured to obtain a battery dynamic parameter value such as conductance. The battery is measured to obtain an open circuit voltage, a resistance and a recovery voltage differential. A condition of the battery is determined as a function of the measured battery dynamic parameter, the open circuit voltage and the recovery voltage differential.
