Abstract
A method and apparatus for determining the cold cranking ampere (CCA) value of a battery under test in which an algorithm of battery CCA as a function of battery internal resistance (IR) is provided, the IR of the battery under test is measured, and the measured IR determines the CCA value of the battery under test from the algorithm. The method and apparatus are used either in a vehicle in which the battery is installed or on a stand alone basis.
