New from 2022: main switch function
All Büttner Dometic LiFePO4 batteries from model year 2022 onwards are equipped with a main switch function. When this is activated, the battery terminals are completely de-energised. This prevents the on-board battery from discharging unintentionally, even when the vehicle is parked for long periods. The battery can also be de-energised without much effort during servicing. An additional power supply output is available for important memory functions.
