MCU W battery operation and maintenance

The MCU W kit contains two batteries. One battery should be placed in the joystick, whereas the spare one should be kept in the cradle where it is continously recharged when the cradle is powered and switched on.

MCU W first usage

Before using the MCU W for the first time please check the batteries for damage or leakage. If either is found do not use. When the batteries are shipped they are usually 30% charged and can be used immediately.

The battery status is confirmed by:

  • the charge power status LED
  • the screen display

When the battery status is low, which is indicated by the charge power status LED or the screen display, please replace it with the spare battery from the cradle.


A new battery powers the MCU W for at least 8 hours under normal usage conditions. Elevated temperatures will reduce battery life. It might not be necessary to exchange with the battery in the cradle, as the joystick battery will be charged each time the joystick is replaced in the cradle. The batteries supplied with MCU W should be swapped at least once a month.
