Abstract
Battery life estimation can be performed by using an algorithm and parameter values for the algorithm, scaled according to the type, e.g. capacity and chemistry, of the battery actually being used. The result of the algorithm may be scaled according to the expected current demand of the apparatus being powered by the battery. A parameter of the algorithm may also be varied if it fails to meet a predetermined fitness criterion during discharging of the battery.
