A battery used exclusively by the living area of an RV, and not to start the vehicle. The more deep cycle batteries, the greater the longevity of your onboard power. The batteries are charged as you drive (if the tow vehicle is equipped with a charge line), when you are hooked up to 120 volt power (if the RV is equipped with a charger), by a generator, or by solar power.
