A charger and a method for charging a battery pack having a plurality of battery cells is presented. The method includes measuring the voltage of the battery cell(s), comparing the voltage measurement(s) of the cell(s) to a target charge voltage value and if the voltage measurement(s) of the cell(s) is not greater than or equal to the target charge voltage value than setting a current for the battery pack based on the voltage measurement(s) of the cell(s).
