I have never understood this preoccupation with using leisure batteries. Just wire it in to your van battery and be done with it, problem solved. Mine's been like that since the van was new, 3 years now and battery is still fine. The van starts on the button even in this weather.When I had a trolley system I was forever having battery problems and buying new ones. I honestly don't even give it a thought anymore.
