Using the USB port in the back of the Wii, this charger from Sanko will add what the Wii should’ve had when it shipped…. rechargeable battery packs. Looks simple enought to use. Plug in the charger, replace the battery cover on the Wii-mote with the battery pack and bingo. Done.

Charge time is about 3.5 hours for 25 hours of play. Identical to the system from Nyko coming out at some point, though this one sells each charger separately whereas the Nyko has two cradles in one unit. Single charger is $29, dual is $53.
