    I have a Elecsol 125 carbon fibre battery and was thinking of adding another
    I also have a 100w solar panel.

    Can I buy another matching battery.......( the one I have must be less than 18 months old ) or is it better to have a new matching pair.

    Im sure I read somewhere that you should start again with 2 new ones ?????

    Idealy Barry you should start with two identical batteries in age and everything else.............If you don't , the older unit will drag the new one down as it deteriorates

    In theory...Yes....however, in your case, a new battery of the same size and type should be fine.

    Is that because its relatively new?
    Certainly buying one is going to be a lot cheaper.

    Yes! Assuming your current battery is in good condition and only 18 months old it's a perfectly reasonable match.

    if you really want to get picky....no two batteries of identical make and age will have exactly the same internal resistances anyway, so why worry ?

    My RV has 4 different makes and aged batteries and copes quite well :thumb:
