Do I Need A Deep Cycle Battery In RV?

    Updated December 11, 2022

    Yes, you should always utilize a deep cycle battery as a house battery in your RV, to answer your question simply. Your generator won’t start any better whether you use a deep cycle battery or a conventional car battery.

    The car battery will eventually need to be changed frequently. Deep Cycle batteries are made to receive repeated charges. Batteries for automobiles are not intended to undergo frequent deep drain and recharging. The house batteries are being recharged each time you plug in or use the generator. Since automotive batteries are not made to undergo repeated deep discharge/recharge cycles, you will need to replace them more frequently and won’t ultimately save money.

    It’s comforting to know that a deep cycle battery, as opposed to a vehicle battery, can run your RV’s 12-volt system for a longer amount of time in the event of a generator failure or a power outage.

    The next decision is whether to utilize two 12 volt deep cycle batteries connected in parallel or two 6 volt batteries connected in series if your RV has space for more than one house battery. To learn the solution, watch the video below (which may surprise you).
