The power supply mode of small new wireless Bluetooth mouse is a section 1... 5V AA battery, also known as the No. 5 battery, a No. 5 battery can probably meet several months of use.
The battery of the mouse is located on the back, and the battery can be replaced by opening the baffle. We have a No. 5 battery built into the box of the mouse, which can be used by users.
The advantage of using AA batteries is that when the battery runs out, you can directly replace a new battery without charging this step.
