I bought a used wii a few days ago from gamestop. so far everything works perfectly. they gave me a rechargable nyko battery with the wii remote. my friend brought over his nyko charge station so he could try to charge it. the blue light came on first and then the green light came on. we charged it for about 2 hours and the wii remote still didn't work. when I put regular batteries in the wii remote it works with no problem. can anyone tell me what could be wrong with the nyko rechargable battery? why does the battery say its charging but the wii remote doesn't come on?
