Things You'll Need
Instructions
Purchase a very strong adhesive like Gorilla Glue, Krazy Glue or Super Glue. All of them will work just as well as the next.
Prepare your PSP battery cover by sanding the broken edges. Sanding makes the plastic more porous, which allows the glue to act as an even better bonding material.
Remove the cap from the glue that you purchased. Squeeze a little bit of the glue onto a paper plate. Take your small paint brush and place it into the glue. Brush the glue onto the battery cover along the break. Connect the two pieces of plastic together and hold it for about five minutes until it sets.
Repeat step 3 if you have more than one piece to reapply. Allow the glue to set for five hours before you reattach it to the back of your PSP.
