    Hello
    can anyone give us advice on how our batteries should be connected. i know it sounds daft and i am not generally a daft lad, but i cant understand why the leisure battery is connected to the coach batteries. when we were away on our first trip the batterries went flat even after being hooked up.am i missing the point here somewhere. any thoughts would be good.
    geoff & lynn.

    For my edification, could someone confirm the use of the terms leisure battery and coach battery. In the first post, coach battery appears to refer to the starting battery, while leisure battery appears to be the battery that runs all the non-chassis 12V stuff.

    We Yanks use slightly different terminology:

    Chassis or stating battery: Starts the engine and powers head/tail/brake lights, indicators, dash and, in the case of petrol engines, ignition. Often, the entry steps are powered by the same battery.

    House or coach battery: Powers all the 12V stuff in the living area, including lights, refrigerator, and slideouts.

    Diolch yn fawr as we used to say in Wales, or ta much.

    Thanks Terry. I'll get our Glossary of RV Terms updated to cross-reference Britspeak for batteries. That way, when folks ask about coach batteries, we know they really mean coach batteries.

    Hi Tom just to make things as clear as mud on most British vans the starter batt only runs the van side of things-starting ,lights indecaters etc,the leisure battery runs just about everything in the caravan (back) side of things -lighting, heating, tv,etc,Then we have relays which charge leisure batterys from engine and also run fridge (12v)whilst engine is running:Rofl1::Eeek: clear?:Doh:

    :RollEyes: Not necessarily so. Our 1989 Kontiki allows you to switch between the Starter and the Leisure battery. :Wink:

    To be honest!
    I don't like the charging relay thingy's!
    In my transit i had a battery isolator switch fitted on a butchered jump lead between the starter and the habitation batteries and just switched over when i wanted to charge either!
    I found this way charged much quicker and you could use the habitation battery to boost the starter if it was needed as well as the habitation hook up charger!
    I had two basic battery testers connected to monitor charging which gave me far more information than i have now!
    All in all the set up in the van was much better than the set up in the Kon Tiki.
    I could charge to capacity 3 lorry batteries i had for habitation with the van idling for an hour and a half using a cup of deisel!
    I know a lot of diesel fitters set up their vans this way and was wondering if you guys knew any reason why i shouldn't do it to the Kon-Tiki!

    Thanks Terry, we have that stuff on our coach also. If you want to see some battery fun, we have 15 batteries on our boat:

    • Each of the 660 HP CAT engines has a large 8D battery for starting.
    • 2 more 8D batteries are connected in series to provide 24V and high current for the bow thruster. (It takes some oomph to move 50,000 lbs/25,000 Kg sideways.)
    • The 10KW generator has a dedicated car-style battery for starting.
    • 10 golf cart style 6V batteries connected in series-parallel provide 1100 amp hours at 12V to run the inverter which produces 120V AC when we're afloat and away from shore power and don't want to run the generator.

    As the 8D flooded cell batteries quit, I replaced them 8D AGM batteries, and replaced the generator battery with AGM also, which makes the job of checking and topping off water a bit easier.

    There are 4 separate charging systems on board, excluding the engine-mounted alternators.

    Thanks, I think. So, if you have more than one type of battery in the system, does that make them co-habitating batteries?

    I don't come here to advertise our forum and think it's bad form to do so. But you could Google us; We're the oldest RV-related online forum and claim to be the friendliest place on the web for anyone with an RV or an interest in RVing. You'll know you're there when you see the real me in my avatar and my name below it.

    John,

    It's always a big ouch when they fail and I have to dig deep into my pockets.

    can you not do some diy recycling and fix the dead ones to a length of chain, chuck 'em overboard and use 'em as sea anchors.:Rofl1::Rofl1: bet they weigh a ton.:thumb:

    Good idea, but the environmentalists would get me hauled into court if I did that.

    LOL Terry, not a bad idea. That would save a lot of fuel, but the boat would only go sideways :BigGrin: BTW there are two of those big CATs on the old tub and they suck a lot of fuel. Makes filling the coach seem cheap. It's all relative I suppose.
