    hi there guys im having a little problem with my leisure batteries there only a year old and knackered so time for new ones my thoughts were on 2 x 110 ah batteries but when i started looking i noticed 1 x 220 ah battery this sounds strange but does 2 x 110 batteries charge quicker or same time as 1 x 220 ah battery via solar panel also whats better idea to go for 2 x 110ah or 1 x 220 ah ? i dont really know much about the way they charge i was thinking 1 x 220ah but got told that it might take longer to charge .......i would of thought 2 seperate batteries would take longer im so confused please help

    Both the same number of amp/hours so same amount of time to charge, 2 batteries would be easier to handle that's my thoughts.

    I have not heard of a battery that big but that doesn't mean too much

    two points from me

    1, if you can get them that big you might need to modify the mounting as it will be physically much bigger than your 110A

    2, from experience we effectively lost the use of both batteries when one failed, so one might be a better option

    As for charging benefits, over to the rest of you :thumb:

    The first thing is how much room have I got ?
    Can I lift a big battery into the space ?
    And if I have 2 or more batteries and one is duff, and I take it out of line, :winky: have I still got power. :Smile:

    We have 3 x 85ah batteries = 255ah and it works for us. :thumb: Bob.

    Newbie question...if you have a solar panel fitted is there really any need for large capacity storage batteries?

    Iwould say 2x 120a batteries is the way to go, due to weight and storage, but first i would investigate why you only got 1 year out of the ones you have it could be they have been damaged by over charging or over draining,

    decent amount of storage covers you for days when there is inclement weather.

    Don't replace the batteries until you've worked out what fried the originals. If you killed a battery in a year, there is something wrong either with your electrical system, or the manner in which the batteries are used. Non traction lead acids do not like deep discharge, whatever the marketing sh*te on the side says.

    However, once battery usage is sorted, there is no difference between 2 x 110Ah or 1 x 220Ah, provided you're strong enough to lift the 220Ah and have room to stick it. Either setup would have ridiculously high CCA and would live or die together. Personally, given identical quality, I would go on price between them.

    I've got a 180Ah, and room for another, if I move the engine battery back to the engine compartment where it belongs...
