"The Wiire had a chance to speak with Lance Barr, a Nintendo industrial designer and the case designer for the American versions of the NES and Super NES, concerning Nintendo Wii´s controllers. According to Barr, at this time, the batteries powering the Wii controller are not internally rechargable.
Barr said that the Wii controllers currently operate on AA batteries, either standard alkaline, lithium ion batteries, or rechargable batteries. Barr stated that, at launch "It´s would be cheaper for us to provide AA batteries," and mentioned that a rechargeable battery pack sold separately might be an option."
