Xbox 360 controllers come with a built-in battery, but if you want to power them yourself you can. Here’s how:
- Open the Xbox 360 case and remove the two screws on the back of the controller.
- Remove the battery cover by gently prying it off with your fingers.
- Place the battery cover back on and screw it in place.
- Close the Xbox 360 case and reattach the screws on the back of the controller.
