No, you usually do not need a battery for most 12V systems in your RV when plugged in. However, devices with high current demand, such as slide-outs, may require a battery to operate correctly. For best performance, check the specific requirements of your devices.
The primary function of the RV battery is to provide power for essential systems when shore power is not available. This includes lighting, water pumps, and other 12-volt appliances. Even when plugged in, the battery helps regulate and store energy. The RV’s converter charges the battery while connected, ensuring it remains functional for when you are not connected to shore power.
In conclusion, an RV does need a battery even when plugged in. It acts as a backup energy source and supports essential systems. Understanding this relationship is vital for RV maintenance and performance.
