How many volts for a wii controller?

A Wii controller, specifically the Wii Remote (Wiimote), operates on two AA batteries, providing a voltage of 3 volts in total. Each AA battery typically delivers 1.5 volts, so when two are used in series, the combined voltage is 3 volts. This voltage is sufficient to power the controller's various functions and wireless communication with the Wii console.
