Abstract
A system and method for providing an application-independent estimation of the state of health (SOH) of a battery. A battery terminal voltage, under a non-zero load, when a specific amount of charge has been drawn from the battery is compared to stored terminal voltage test data obtained under the same conditions. An estimate of SOH is provided in response to the comparison.
