Nintendo 3DS XL Battery Replacement

Loosen the two 4.2 mm-length screws located at the top of the back cover.

• The screws have locking washers that prevent the screws from falling off of the back cover. Leave these locking washers on the screws; it is not necessary to remove the washers for this repair guide.

Hold the device so that the cover is facing up.

Using a plastic opening tool, pry off the cover starting at the top right corner.

• Hold the edge of the cover to ensure it does not reattach.
• Look for the small section below the stylus compartment. Pry off the cover at that point if it is still attached.

Take off the cover of the device and set aside.

Insert the plastic opening tool into the opening located on the right side of the battery.

Pry off the battery from the lower casing.

Lift the battery out of the case and set aside.
