Looking at 2-12 volt Exide 27mdc batteries. They are deep cycle and not starting. We do a small amount of camping using a generator. how do the Exide batteries hold up compared to Interstate?
Personally, I'd opt for 2 6v golf cart batteries, instead. They are =true= deep cycle, meaning they can be repeatedly be drawn down to low levels and recharged without damage. Not many 12v batteries can stand this and, of those that can, they are =expensive=. 2 6v golf cart batteries from Sam's/Costco and a cross-over cable should run you right around $200-225.
