In a method of charging a battery cell, having a positive terminal and a negative terminal, a charging current is applied to the battery cell. A voltage is measured between the positive terminal and the negative terminal. The charging current is removed from the battery cell at a predetermined period subsequent to when the voltage changes at a rate, relative to time, that is not greater than a predetermined threshold. A battery cell charger for charging a battery cell includes a charger circuit, capable of applying a charging current to the battery cell, a voltage sensor circuit that measures a voltage between the positive terminal and the negative terminal and a charger control circuit that is responsive to the voltage sensor. The charger circuit directs the charger circuit to apply the charging current to the battery cell while the voltage changes at a rate, relative to time, that is greater than a predetermined threshold and directs the charger circuit to cease to apply the charging current to the battery cell at a predetermined period subsequent to when the voltage changes at a rate, relative to time, that is not greater than a predetermined threshold.
