I’m interested in learning about how long I could expect to run my residential refrigerator on twin 12V batteries. Obviously, I could just experiment, but I’d like to have a good idea of what to expect before doing so. If I installed and connected the batteries the night before bringing the RV to my home to load up gear and food, can I expect the batteries to last through the night… say, 12 hours, or would they likely discharge before that length of time? I’m unable to park my RV at my home over-night due to local ordinances. But I’d love to have the refrigerator already cold in the morning to be able to load up and leave earlier in the day. In a perfect scenario, I could connect just one of the batteries to run the refrigerator, then have the second battery for keeping the refrigerator cold while traveling to my destination. I’m not yet familiar with how much charging of the batteries takes place while I’m driving (if any at all)?
