Aux heater stopped working overnight

I have just had this problem overnight. Had to restart the vehicle for 5 mins and it would work again for a few hrs. In the manual it says “if the battery voltage drops below 11.5 volts the auxiliary heater cannot be switched on” see pg 49 under battery charger. So mine is 90% charged so I will try a new battery I think…

Ignore the %, it's the voltage that is accurate. Which vehicle do you have and how old?

I had the same problem when we did not have an electric hook up. Leisure batteries only last 2 without starting the van. I fitted a solar panel to increase the time, but not tested off grid since I fitted it.
