Instructions
Remove any rubber jackets or accessories covering the Wii remote. The contacts on the battery must connect with the metal contacts on the charging station. Covers on the remote prevent the connection.
Make sure the Wii remote has the battery cover supplied with the charge station. The standard Wii remote battery covers don't have the hole for the battery charger contacts.
Verify the charging station is plugged into the wall outlet.
Remove the battery if the Wii remote will not power on after you charge it. Bend the contacts on the bottom of the battery out slightly, then bend them back. The contacts will protrude slightly and give better contact with the connections inside the Wii remote.
Repeat the pairing process between the remote and the Wii if the remote turns on, but the Wii console does not respond. Turn on the Wii and open the cover on the front of the console. Remove the battery cover from the back of the Wii remote. Press and release the "SYNC" button on the Wii console and the Wii remote.
