Abstract

A method for predicting the remaining life of a battery for a vehicle includes obtaining a value representative of the amount of remaining life for a battery in a new and fully charged state and monitoring at least one parameter of the battery during use of the battery. The method also includes obtaining an acceleration factor based on the at least one monitored parameter and estimating the amount of life lost from the battery utilizing the acceleration factor.
