The batteries were deep cycle marine batteries and weighed 7lbs less that the golf cart batteries right next to them on the rack. The both of larger batteries had to have their respective boxes rebuilt to hold the new batteries. Due to the shape and configuration of the battery cabinet the 12 volt batteries were less work (in construction and wiring) than a rebuild for the golf cart batteries which were much taller. The old batteries lasted 5 years with half the capacity we have now. And we never ran out of power with them till last month. so for us, the replacement 12 volt deep cycle batteries was the easiest path.
