If your Gartenland Lawn Mower displays error 'CN104: Battery over heating', it indicates that the battery temperature is above 60 °C, preventing discharging. The electronic control unit will initiate an emergency switch-off. Do not place the mower on the base station. Switch it off and allow the battery to cool down.
