Abstract
A method of charging a cell of a battery includes the steps of: applying a test current to an input terminal of the battery; measuring a voltage output, wherein the voltage output is comprised of a voltage of the cell and a voltage drop, induced by the test current, across an internal impedance of the battery; and applying a charging current to the input terminal of the battery if the measured voltage output is higher than a predetermined voltage, wherein the charging current is greater than the test current.
