No - I have never recharged them. This might be a stupid question, but are the batteries that are provided with your Wii-mote rechargeable? I am not much of an instruction reader - just jump right in and use things, so I did not notice. Good thing I have not thrown them away if so. Again, I have never recharged the batteries. They just worked completely fine from Xmas until either Wed or Thurs of this past week. I did notice when I was trying to figure out how to calibrate my Wiimote from Wii Play that they were running low from the indicator you can go to, but they lasted since whatever the first week Wii Play came out.
