A computer-implemented method enables capacity based pre-charging and age based permanent failure detection in a battery. The method comprises detecting, via a controller, a real time cell voltage for at least one cell in the battery. The controller determines if the real time cell voltage is less than a normal operating cell voltage. In response to the real time cell voltage being less than the normal operating cell voltage, a capacity based pre-charge value is calculated based on a full charge capacity and at least one cell parameter of the cell. A pre-charge time is calculated based on the capacity based pre-charge value. A pre-charge voltage is identified. The battery management controller is triggered to pre-charge the battery using the calculated pre-charge time and the identified pre-charge voltage.
