Although I did not wild camp alot last year I find after three years my leisure battery is no longer holding the charge I purchased a new one from E Bay and fitted same but having looked at the free space in the area I am considering linking another any advice on this procedure guys and gals
Just connect them in parallel i.e. positive to positive and negative to negative, with a suitably heavy wire. I used 30A, but I don't have a split charger to get engine charging. Ideally they should be of the same power capacity, although I have a 110A/hr and an 85A/hr connected together with no problems.
Thanks for the info just chatting to a mate about it and he said if I was wanting two batteries for longer time camping without electric then you have to put something in the linking as all I have achieved in strapping two batteries together is an increase in amps they will both run down together he suggested a switch of some kind so that when one has gone flat you switch to the other
2 identical batteries connected in parallel will double amp/hrs, ie doubling both amps & life before going flat. Amp/hrs is a measurement of battery capacity so a given piece of equipment will run twice as long with 2 batteries in parallel, which is what you want.
Its pointless connecting the batteries if you are basically going to use them one at a time. Hooking them in parallel will see them run down at the same time, but should last twice as long as a single battery.
Guys, I'm no expert, so I'm only reporting this: our leisure battery cover is in the attic because the previous owner changed the small leisure battery for a much bigger one so it would last longer on his fishing trips (or so he said). Wires same, we haven't had any problems.
