Lenovo wireless mouse generally uses a built-in rechargeable battery, which can be connected to a computer or charger through a Micro USB cable for charging. First, plug the Micro USB cable into the charging port at the bottom of the mouse, and then plug the other end into the computer or charger to charge.
When the charging indicator lights up, it means that it is charging, and it usually takes 2-3 hours to be fully charged. After charging is complete, unplug the charging cable and use it. Do not bend or damage the charging cable during charging.
If you buy a rechargeable battery, put it in a rechargeable battery bin
