My recent cruising trips have brought up an issue that is bothering me. I have to run my generator for hours every morning and every night. I'll run them for lets say 3 hours in the evening then wake in the morning and be down to 60% or less. I have four D8 wet cells. Two to start and two for the house. My electrician told me that my port start battery was separate but the stb start was part of the house bank. To be safe there is a battery combiner, and I have jumper cables in an emergency, and I have two generators, one with its own battery. My big loads are a residential refrigerator freezer with 120v 6.5 amp draw. So that is like, what?, 70 amps through the inverter? Then I have a newer small cooler in the sun deck with a very small ice cube tray area. I can't remember the draw right now. Is this enough to drain my batts in eight hours or less?
Ok, next question. Assuming the batts are getting weak, what should I replace them with. I have Cat 3208s that take some CCAs to get going. I started looking into Lithium-ion but not much cranking power. What about all 6v gold cart stuff?
