In case your PSP battery breaks and you find it too expensive to buy a new one right now, take this lead from LordLeXat and use your Nokia battery as replacement. That's some real MacGyver shiz right there.

If we are to believe LordLeXat's testimonial, this makeshift battery actually lasts longer than your usual PSP battery. Says he, "The battery is lighter and has nearly 150 lifetime of the original 1800mAh PSP battery, and by the way, the text of the Nkia battery reads 1020mAh."

How did he do it? Looks like he used a standard Nokia battery (BL-5C) pack with the original PSP battery control board. You can try it out for yourself, but you know it's at your own risk.
