Things You'll Need
Instructions
Open the PSP's battery slot on the back of the PSP by pushing in the battery release button. Pull the PSP battery out of the PSP.
Hold the PSP battery in the hand opposite your dominant hand. Slowly begin to score the plastic seam that goes all the way around the battery using a knife or box cutter. Under no circumstances insert the knife or box cutter into the battery.
Continue to lightly score the seam until the top battery cover comes off. Locate the black "ICO4" circuit on the bottom of the battery's motherboard.
Use the safety pin to carefully pull the fourth pin on that circuit off of the motherboard. The pin will turn copper when it is fully disconnected.
Place the battery cover back onto the battery and snap it back into place. The PSP battery can now be used as a Pandora battery.
