    Alarms and immobilisers can drain the engine battery over a period of time unfortunately

    hi peter thanks ....I had a feeling it was going to be flat for the reasons you give.. what I am not sure about is if you are on hook up doe's that charge the engine battery as well as the leisure battery phil

    Hi

    It's very doubtful that your engine battery is charged from the EHU .. not many have that facility.

    If the van is in secure storage I would disconnect the neg on the engine battery .. it will then stay fully charged for many weeks ..

    On my Lunar the charger will charge which ever battery is switched to supply the habitation 12v electrics. I dont know whether this is the same for all but it may be worth checking.

    thanks guys , if it has not charged the engine bat. at least I will have a full leisure bat and can jump start the van from that with luck I have read you have to ( when jumpstarting from another car ) connect + to + and put the -to the engine block on both cars but what about conecting from a spare bat ?

    On my old Hymer the habitation and service battery are side by side in the floor.
    In an attempt to get moving one morning (after I had left the road lights on all night:Doh:) I laid a spanner over the 2 positive poles, stood on it, and turned the key = instant start.

    There are those who will advise NOT using a leisure battery for starting but when faced with a missed appointment/ stuck in middle of nowhere some lateral thinking is needed and it was just once! (unless you count the time we----- and the time!!!)

    I went up to my friends boat at the Falkirk Wheel to help him change his engine battery which had packed in. He bought the boat second hand over two years ago so the battery could be anything over 2 years old. We removed the old one which was not easy because it was tucked well away and discovered it to be, a leisure battery!:Eeek:

    hi wallace ,, in the good old days before eletronic, this and that, not to mention the on bord computer . I would have took the jump leads from the leisure battery and stuck them on the Engine bat .. but there are just to many expensive parts to burn out these days ... looks like a trip to halfords and one more bit of kit I did not know i needed ie battery charger

    So far I have I am still using the van whenever we can squeeze a couple of days away, but it has sat still for 4 weeks once and the battery did get a little low ( alarms etc )

    Going on a hookup brought both batteries up to full steam ok ( Miller States 'Alabama' )

    Hi Phil

    you may want to consider fitting a battery master which will charge your engine battery from the ehu or solar panel ( if fitted)

    Do not jumpstart from a leisure battery, as you could easily buckle the plates. Leisure batteries have thinner plates than the cab battery and do not like supplying sudden large current.

    No, but you didn't say what I was saying.
    Don't use a leisure battery to jump start the engine.

    Theres no need to be so rude! I only offered my advice!

    How was an enquiry rude?:Doh:

    Surely using a leisure battery to start an engine for over 2 years is a bit heavier than using it for a one off jump start.

    I only offered First Hand advice.:Sad:

    The 'leisure' batteries on RVs are generally used to start the on board generator and also as a back up to the main engine battery..
    There is an Emergency Start switch on the dash that connects both sets of batteries.. so using a so called leisure battery occasionally to start the engine will cause it no harm.

    The facts are that leisure batteries are built to run lower loads for a long time. However Starting batteries can give a very high current for a shorter period. They are manufactured differently the leisure battery has thinner plates that will buckle under heavy load.

    There are some batteries that different but a pure leisure battery can be damaged by starting an engine.

    Obviously starting a smaller engine like a generator will not put anything like the load that starting a high compression diesel engine would put on the battery.

    Just the point I was trying to make Jim, saw it with my own eyes and it made me think just how much other theoretical problems are actually urban myths.:Eeek:

    Do you think my friends boat has a steam engine then?

    As said, theory and practise are not always the same, the point of my earlier post, but some choose to believe what they read rather than what they experience, not me though.:Wink:
