i have a psp 1001 running cfw 6.39 me-6 and 2 batteries that are acting up. both are off brand 3.6v 2200mAh (one gold lettering one white lettering) the gold lettering one after full charge drops to 66% in less than 3 min of use. the white one drains quickly(2-3hrs). i recently discharged both in an attempt to reset the percentage to absolute zero instead of what my psp thought was zero. neither battery operated at full potential from the start, i wast to get the most out of my batteries. any ideas?
