Parasitic loads like gas detectors, clocks, and other small electrical devices drain power when your RV isn’t in use. If the power gets too low, it can hurt battery life. Your RV should be equipped with battery disconnect switches to prevent this, so don’t forget to engage them when the RV is off or in storage.
