How to Remove the Battery From a Wii System

Electronics have certain data that needs to be stored, even when the power has been turned off. Devices that use these types of batteries, which can last for up to 10 years, include computers and most major gaming consoles including the Nintendo Wii. The internal battery of the Wii is responsible for keeping the date and time current when it is unplugged from a power outlet. Occasionally these batteries can fail and need to be replaced.

Things You'll Need

• Phillips head screw driver

Instructions

1. Unplug any USB devices and game cube controllers that are plugged into your Wii. Also be sure to take any SD cards out of the slot.

2. Turn your Wii upside down with the serial number sticker facing you.

3. Unscrew the single Phillips screw on the bottom right of the Wii.

4. Remove the cover. This is where the battery is stored.

Tips & Warnings

• Do not worry about voiding your warranty when you remove the battery cover. The primary components that are protected by Nintendo require a Triwing screwdriver, which must be custom ordered.
