Leisure battery care and charge advice please

Hannah Wilson

Right, leisure battery new 2 years ago when we got the van, not really done anything to it as we use sites, but dabbled in a bit of "wilding" couple of weeks ago and battery only had enough to power the toilet flush and the hob spark. So after having to
dismantal the hand break, remove the whole drivers seat, just to get the sodd*** thing out!

I tested it, reading 6.29v so now it's on charge! What happens now once it's fully charged? Do I have to keep the van hooked up to the power for evermore? 

Its 85ah would this last a couple of days, say two hours of tv a night (40w)?

please help
