Comes with 2 rechargeable batteries (rechargeable battery) and 2 specific valves (the connector on the charger being at the back of the Wiimote level and not where you can plug the nunchuk (below). Requires removing the protection rubber Wii Remote time of the load. Rather fast charging (3-4 hours). I played for 2-3 hours, and the Wiimote is charged in 5-10 minutes.
