Abstract

A computer-implemented method and information handling system manage a rate of decreasing full capacity of a rechargeable battery by using a projected/target rate of decreasing charge capacity for the battery. The method includes determining an actual rate of decreasing charge capacity of the battery, comparing the actual rate of decreasing charge capacity to the projected/target rate of decreasing charge capacity to determine whether the actual rate of decreasing charge capacity is greater than the projected rate of decreasing charge capacity, and if the actual rate of decreasing charge capacity is greater than the projected/target rate of decreasing charge capacity, modifying one or more variable parameters to slow down the actual rate of decreasing charge capacity of the battery such that the actual rate of decreasing charge capacity remains within a range of the projected/target rate of decreasing charge capacity, and charging and discharging the battery using the modified parameters.
