This has happened twice now. I own a Flat panel Energizer Charging battery system for my Wii. When I place my Wii remotes on the panel it charges the Batteries. But for some reason 2 of my batteries won't charge. They sit on that panel for hours, even days and they won't activate my remotes. I checked online and they don't sell those certain batteries separate for that panel. Is there a way of fixing them or can I just buy some regular rechargable Energizer batteries and replace the ones that were included in the Charging panel?
