Charging the camping battery - Travel Home (Mercedes Marco Polo)

You can charge the camping battery while driving or connect the van to an external power source. To do this, you must connect the supplied cable (20 metres long) from the plug on the driver's side of the camper to a power source. The vehicle will indicate that the battery is charging by turning on an indicator light on the caravan unit. The 230V sockets should now be working.


If they do not, check that the RCD is switched on and that the power source is working properly. The RCD switch is located on the kitchen unit, behind the driver's seat and under the 230 socket:


Please note the following:

  • Do not forget to unplug the power cable before driving off! To do this, press down the blue lever to the left of the plug.
  • With a fully charged battery, you will be self-sufficient for about 2 days without electricity. Then you have to drive again for some time to recharge the battery or connect your camper to an external power source.

You can check the charge level in the on-board unit:


Please note that campers cannot be charged at the stations for electric vehicles.

For deeply discharged camping batteries

As camping batteries are not lithium batteries, we advise you never to discharge them below 30%. This can damage the battery. If you suspect that the camping battery is deeply discharged, try the following:

  • Connect shore power and run the engine.
  • Try this for about 30 minutes. The extra amperage can bring a deeply discharged battery back up to speed.
