I was in the middle of fighting Bowser at the end of Super Mario Galaxy earlier when I was presented with a fearsome message that my Wiimote was not responding (dead batteries). After looking around the house and trying two pairs of batteries I realised everything I had was flat and that I would need to go out and buy some batteries to finish the boss. Luckily, just as I was about to leave a friend suggested I check in my camera and, lucky me, I had a working set of A batteries there. It seems like a bad idea to use batteries that I end up having to replace often though because of the cost and I doubt it's very environmentally friendly. Which brings me to the question: What rechargeable batteries do people recommend for the Wiimote? I was looking into USBcells but I heard that they don't hold much power. I would rather get rechargeable batteries than one of those wiimote power pack things as that means I can also use the batteries for other things.
