Things You'll Need
Instructions
Remove the battery from the PSP.
Insert one end of each wire into the two terminals, one to the positive and one to the negative. Make sure that the wires do not touch one another.
Wrap the foil around each loose end of the wires, making sure that the wires themselves do not touch.
Allow this connection to sit for about 30 seconds.
Remove the foil and wires, and put the battery back into the PSP. It should be able to take a charge, although you will now need to fully recharge the battery before starting your PSP.
