I have a pandora battery (hard-modded) (phat 1800 mAh) that used to work perfectly but now it doesn't work. I thought it might be dead but when I tried to charge it the orange charge light just flashed for a few minutes and then the light went away. I've tried doing this by turning on the psp with AC adapter then putting in the pandora battery, but to no avail. How can I charge/use my battery??:confused:
