Abstract

A battery device includes a main body and a rear cover removably connected to the main body. The main body has a first battery receiving compartment. The rear cover has a second battery receiving compartment. The first battery receiving compartment is configured to receive at least two batteries while the second battery receiving compartment is configured to receive at least one battery. For the battery device, since the back cover is provided with the second battery receiving compartment cooperating with the first battery receiving compartment in the body, the apparatus applying the battery device has at least two supportable power levels. In this way, the battery device can be switched between a low power and a high power, eliminating the need of another battery device.
