Answer 1

Most likely this is the case: The device needs a voltage, say 4.5V. Batteries are about 1.5V, so you need three batteries. Using 1 or 2 won’t work, voltage too low. Whether it’s AAA or AA depends on how much power the device needs to draw, usually balanced with the room the device has for batteries.
