Battery

[AdrianCaltieri]

After three nights without hook up the control panel was showing 11.9v 80% but the engine was a bit reluctant to start. If the leisure batteries drain, does the "starter" battery also drain or are they separate battery/circuits? Thanks for any advice.

Separate. Your starter likely drained from opening the doors too much, esp drivers, or using the radio.

I suggest you ignore the % reading. It is a very iffy calculation. The voltage is however accurate.

There is no connection between leisure and engine electrical circuits, but the starter battery can be seriously drained by frequent use of the infotainment system, using the lights next to the rear view mirror and repeatedly opening the drivers door. Also, if you have the full electric sliding door then that can also drain the engine battery. Switch to Manual mode.

This is a great posting, thank @WelshGas. It is a great reminder to keep the battery in mind when opening doors, etc.
One thing puzzles me and that is the reference to switching to manual mode for the sliding door. Does the 6.1 have this option?

I’m sure it has.

I'm hoping for an answer to... "switching to manual mode for the sliding door. Does the T6.1 have this as an option"

Have you looked at the Dash? There should be a switch to open/close the fully electric sliding door and another switch to switch it off into manual mode,
The T5/6 had it so I would be very surprised if the T6.1 hasn’t. It is a function of the Transporter base vehicle and not exclusive to the California.
