Instructions
Connect the 5-pin end of the USB cable into the USB port on your PS3 controller.
Locate an open USB port on your computer, and then connect the other end of the cable to the port. The LED lights on the controller will flash, indicating that the device is charging.
Disconnect your controller when the LED lights stop flashing. This indicates that the controller's battery is fully charged.
Press and hold the "PS" button for more than one second, when the device is connected to the game console, to check the battery charge level on the screen.
