    I am thinking of having a 2nd Leisure battery fitted.

    Will this battery be connected to the original in parallel therefore effectively doubling(based on similar AHC) the capacity or is it an independant battery i.e auxiliary battery which is used whilst the other is being recharged via the solar panel or the next engine run?

    Are there any other considerations I should think about before venturing into the land of 2 Leisure batteries.

    Yes you connect them in parallel, as many as you like as long as you have the space for them. Solar panels will charge them all simultaneously, will just take longer to charge more batteries, but equally you can run things for twice as long with two liesure batteries sharing the load. I wish I had space for more than one liesure battery because at this time of year my panels are giving me more power than I can store, although in the middle of winter it's a different story!

    Yes you normally connect them in parallel, batteries must be of the same type i.e. both both Gel or both Wet Cells. Ideally they should be the same age if your existing battery is more than a couple of years old it would be best to buy 2 new ones.

    Thanks for the replies...

    Fortunate in that my 1st leisure battery is only 2 months old so will have a pair of good 'uns.

    when you connect them up please connect them using two fuses.

    this diagram will explain why.

    Unexpected expense, but I thought I start with a clean slate.
