Abstract
A method for determining an end of life of a battery includes determining a discharge capacity of the battery at a given moment in time, determining a discharge capacity at a functional endpoint of the battery, and determining a fuel remaining in the battery at the given moment in time as a function of both the discharge capacity at the given moment in time and the discharge capacity of the battery at the functional endpoint of the battery. The determined fuel remaining is indicative of an end of life of the battery.
