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?
Everyone likes to buy a brand but read the specs before buying anything. Cram as many amp hours as possible into the battery compartment. Group 27 batterys are better than the stupid little group 24s the builders usually install.
If space allows, get a pair of group 31s, a single 4D, or even an 8D if there is room.
