[quote name='bugeeker']Nope, play-n-charge cables do NOT work to charge rechargable AA batteries. but investing in your own set of rechargable AAs, and a charger, is likely worth you while. As mentioned, you can then use those batteries for other devices too.[/QUOTE]
I've got a big Radio Shack charger, but sometimes the controller dies and you can't find any more batteries with a full charge! I usually just steal the batteries from the Wiimote, or vice versa.
