A method for estimating state-of-charge of a battery cell includes suppressing full execution of a capacitance-estimation algorithm for as long as a parameter does not exceed a certain threshold. The parameter is either a measured voltage value across the cell's terminals, the cell's estimated state-of-charge, or an amount of charge passing in or out of the cell during some interval. A battery-management system triggers full execution when the parameter falls below the threshold, or, if the parameter is the amount of charge passing, when it rises above the threshold.
