Depends on your mileage Wether it will keep it topped up .I use a car battery rather than a leisure battery , they cost peanuts from the scrappy and work fine .
I used to think they guys who were buying old car battery's from scrappys were just being tight. I've fried 2 leisure battery's in as many years. Over £100 each time. I'm now running a car battery from the scrappy. Cost me a tenner. Works a treat. I'm 3 months in. I wonder if it'll last me a year or so? Something tells me it will.
we run two pumps off one leisure battery, we charge it on a trickle charger every night, works fineGraham
well my car battery has been on 18 months (its a 100ah /900 amp cranking battery from a scrapped van) it also came in very handy when i left the van lights on and flattened my battery .set of jump leads from system battery to van battery , no waiting an hour for rac
