About this deal
A size #00 crosshead screwdriver will be required to remove the battery from a Nintendo 3DS XL system. Adjust the screen brightness according to your environment. Lowering the brightness to a tolerable level, if you can manage, will have a drastic effect on the battery life. To remove the battery cover, lift it up slightly and slide it away from the bottom of the system. There are two tabs on the underside of cover. Please make sure the tabs do not catch on anything when removing the battery cover, as this may result in damage to the cover.
