    My 2 new 110 amp batteries have just been delivered and are ready for fitting.However when it comes to electrics I don't know my arse from my elbow,it turns out my recent problems with my blown air heating was down to a blown fuse:Blush
    I'm wondering if there's anyone out there in my area who would show me how to fit them,in exchange for this help I'm offering the existing battery which is a 85 amp battery 3weeks old with receipt.....thanks steve

    not in your area but what is the problem in fitting?

    you can fit all three if you wanted too

    just link +to + and - to - on each battery so you get 12 volts connecting the + on the first bat and the - NEG on the last

    put a 30amp fuse on the + outlet for safety

    not hard to do

    Battery

    Well for a start I was led to believe that batteries only charged to the lesser or weaker one so why connect all 3 if 2 have larger capacities.I wouldn't know where 2get bits from or what bits required.Finally not very confident with electrics and with 2small kids wouldn't want to get it wrong.

    I wouldn't be adding the 85 to the new batteries. My understanding is that you will then end up with 3 x 85s for extra unwanted weight :Smile:

    I was going to take the piss, but now you shame me !

    Halfords will sell the bits. Put a 50A fuse next to each + and connect them to the existing + ( brown or red ? ) wire.

    Connect the two - negative wires together.

    So you need some thick wire, two fuses and connection blocks.

    No. As I understand it if you connect all 3 you will have 110+110+85 Ah. If any of the batteries was damaged then could have a problem but as long as they are all in good health no problem in connecting different capacities.

    The 50A fuse suggested elsewhere will be fine as long as you are not running an inverter in which case you will need something larger and bigger wires to go with it.

    then you were lead to believe wrongly.....a myth.

    you can connect any sized battery to any other sized battery without problem.

    the only time it really matters is if one battery is beyond help.....or is a different type...gel, AGM etc.

    a simple example.

    take a sink basin, a washing up bowl and a large jug.

    basin = 125ah battery, bowl = 100ah battery and jug = 75ah battery.

    now stand the jug in the bowl and the bowl in the sink and start to fill the jug.

    once the jug is full the water will overflow into the bowl and in turn the bowl will overflow into the sink.

    all three are now full.

    same applies to batteries.

    once the 75ah is full it wont take any more charge but the charger will continue to charge the 100ah until that is full, then it will continue to charge the 125ah until that too is full.

    you will then have one large battery of 200ah capacity.

    the charger doesn't 'see' 3 batteries...only one 200ah battery.

    if one battery is faulty or old it will then impact on the total capacity...it wont take/hold a full charge but the two good ones will still be fully charged but will show an overall reduced capacity due to the duff battery..

    be happy to asssist you but would depend on when you want it carried out?

    Rutland I don't think is too far from where I reside and can find you a nice CL and then pop over and sort it out for you.

    Don't need to pay me in batteries, a simple drink would be fine.

    It really is quite simple and would be happy to walk you through it by telephone/email with pictures if you prefered too. :thumb:

    Just let me know.

    Regards

    Paul

    Why not have a trip to Devon, stay at my CL and whilst you are here I'll sort the batteries for you we can get any bits I don't have just up the road. Make a holiday of it. No charge for my time and don't need your battery so link the 3 up together as they are all new ones.
