guys I am so green at this caravan lark even the cows laugh at me , could you tell me how to run my caravan with out a hook up . I have got the part of fridge runs off gas and cook by gas but what about light tv and other stuff how long will a leisure battery last and how do you recharge it over say a 3 day break thanks
How long you could last without a 'Hook Up' depends on a number of thing, the main one being what size is you Battery in Ampere Hours. It could be 80Ah or it may be as large as 110Ah. If you are planning on going 'Off Grid' quit often then you should change any Halogen Lights for LED lights, very often you can just buy LED bulbs to replace the Halogen bulbs.
If you had a 110Ah Battery with LED lights and you used your TV sparingly (I am assuming your TV will work off 12V) then I would think you should get 3 days without charging.
