    hi, looking for some advice, yesterday rang 2 different fitters to get a quote on having 2 new leisure batteries fitted. First one quoted £350 for 100am wet batteries. I then told him it has a gel battery due to being in the cab. He replied that doesn't matter he can sort that and wet batteries are better than gel, but if I wanted gel £600, fitted. Then the other fitter I rang quoted about the same but said gel are a better option and a better battery. If anbody feels like giving advice and help I would well appreciate. Thank you

    Watch these 3 vids before you decide, leisure batteries is just one big con.

    Don't forget to check that your charger is suitable for gel batteries... mine has a series of internal switches depending on battery type and capacity.. may not be critical but just thought I'd mention it

    Thank you all for the advice, especially the you tube videos, now I think I will go with wet batteries, and move them under the bench seat, has I can have easy access to them, I have now found the switch where I can switch from gel to wet , another thing I have learned.

    The beauty of wet is you can add things like B2B or Ctek smart chargers.

    I've put a second battery under my passenger seat, so now 110 amp wet battery under each seat and I drilled a hole down to the outside for each battery breather pipe. The only thing is if leaving under seats, make sure you get low profile battery's.(Hymer B584 2001)

    Before deciding.. a few points to ponder..

    Have you looked at the existing battery cables, will they not need replacing due to the longer run ?

    The 50A battery fuses (mounted under the seat) will also need re-siting

    They should also be inside proper battery boxes and vented to the outside..

    You also lose storage space..

    I ran the wires between the seats. The Hymer floor covering ends level with the front of the seat boxes and then the original fiat rubber floor mat ends just under this and I tucked my wires under rubber mat and then they go under seat box bottom front edge.

    Like Jim I brought a pair of gels from Tanya for £300. Personally I would stuck with the gels, treated right you will get well over 5 years out of them. The seats have got to come out anyway to remove the old batteries.
    Take Sterling's view with a pinch of salt he has very biased opinions.

    Hi manic I am now going to order my 2 batteries. Could I just ask a bit more advice, I have had the drivers seat of today and noticed a 50 am fuse, did you put another fuse with the second battery. Or is it just has simple has wiring the first battery to the second battery.

    you require a 50A fuse at BOTH ends of the cable linking the second battery..

    Hi scotjimland had the seat of today found elecsol carbon fibre mono bloc dual purpose engine start + deep cycle, found out this is a wet battery and should have a breather pipe. So no way can this be the original Hymer battery. Not a happy bunny. Not sure if dangerous or not to late now I have been using for 6 months, but sorting this weekend .

    definitely not Hymer OEM ..

    as you are aware wet cells should be vented outside.. so either replace with two new wet cells with breather pipes routed outside.. or fit GELs
