A charger for a battery includes a power source and a control circuit. The battery has an internal resistance, at least one cell having a recommended charge voltage, and an aggregate recommended charge voltage. The power source is capable of providing an applied voltage and charge current to the battery. The control circuit is connected to the power source and is capable of detecting the applied voltage of the battery and enabling the charge current and applied voltage to the battery until the applied voltage is greater than the aggregate recommended charge voltage by an amount less than the product of the internal resistance and the charge current. The control circuit is capable of reducing the applied voltage towards the aggregate recommended charge voltage at a controlled rate such that the recommended charge voltage of the at least one cell is not exceeded.
