Slide the battery out of the MIM-2, e.g., by inverting the device.
Charge for about an hour, after charging next to the usb-c charging port, the led will light up blue.
Maintain the direction of the battery in the device compartment.
Even if you have a break in the use of the MIM-2 (we do not recommend ;)) remember to charge the battery at least once every six months to preserve its life.
