The tv came with a 12v lead so hopefully
I have 2 leisure batterys in the caravan
Would it be a better idea to use one and charge the other one
Then swap over when the used one is flat( but I suppose you then run the risk of flattening both if cloudy )
Hmmmmm just going with the straight to the used battery , I think
Our tv seems to turn it self on and get left on as the kids pop in to use the loo
Amazing how many times I find it bleating away with no one in the van even when we on battery
Bless them
