How to get my wii controls fully charged ?

Are the batteries regular AA batteries are you using a Wiiremote batteries with a dock charger. Your batteries are probably dead. If they are not rechargeable batteries, just discard and get some new ones. You can go to a dollar store or corner store and get new ones for about $2. It's best to get rechargeable batteries so you won't have to keep buying them all the time. I suggest either Energizer or Duracell Rechargeable. I have the Energizer Power Charger for the Wii and I don't like the batteries b/c they die out to quick.
