In one embodiment, the present invention includes a method for performing a test on a rechargeable battery to indirectly determine a state of protection circuitry associated with the battery. The method may discharge the battery by controlling a pull-down current into a system, determine if the battery voltage falls below a first threshold level within a predetermined amount of time, and if so provide a pre-charge current to the battery.
