Your house battery bank decides how long you can camp without hookups, run the fridge overnight, or power the furnace fan in the cold. The old lead-acid units in many rigs sag under load and die young, which is why upgrading the battery is one of the highest-impact changes a serious camper can make. Below we compare the battery chemistries that matter for RVs, from budget AGM to lithium LiFePO4. We weigh usable capacity, weight, cold-weather behavior, cycle life over years of deep discharging, and whether each type plays nicely with your existing converter and solar charging setup.
