The best RV battery will allow any camper’s essential systems to run for days at a time, whether you’re dry camping, going on an extended road trip, or facing an extended power outage at the campground.

However, the world of RV batteries is vast and complex, and there are so many options to consider. Below, we will break down the various types of recreational vehicle batteries and then review some top-rated ones.

If you’re hunting for the best RV battery, then you’ve come to the right place. We’ve researched extensively and reviewed the best of the best RV batteries you can buy in 2022.

Let’s dive in.

RV Batteries Explained

Motorhomes or drivable RVs come with two types of batteries on board:

Chassis Battery

Also called the starter battery, this is the battery used to start your motorhome’s engine when you hit the ignition. It also operates other automotive systems such as windshield wipers and vehicle lighting. You won’t find this battery in towable RVs.

It’s made with many thin plates to supply a huge amount of starting current in short bursts. It’s rated in Cold Cranking Amps—the ability to start an engine in cold temperatures. Additionally, it’s unable to perform deep cycle applications such as powering appliances, as it isn’t built to provide long periods of power. 

House Battery 

Also referred to as the 12-volts or deep cycle battery, this battery supplies the requisite 12-volts that allow all electronic devices to work correctly. It serves as the power source for all other energy-related applications, such as running the interior lights, water pump, small appliances, TV, and for powering devices.

A house battery is constructed with fewer but thick lead plates to provide relatively smaller amounts of current for long periods of time without needing to be recharged right away. It’s rated in Amp Hours (AH) or Reserve Capacity (RC). 

A 12 volts battery can be charged by shore power, generator, solar power, or even the chassis battery when the RV is driving. Depending on your power needs, you can have more than one house battery on board.

Construction Types of RV Batteries

Deep cycle RV batteries are not built the same. Below is a quick breakdown of the various house battery constructions: 

Lead-Acid Batteries 

Sometimes called a wet cell, lead acid is the most common type of RV battery, and it consists of flat plates of lead submerged in an electrolyte. The electrolyte can either be a liquid or semi-solid gel. These batteries need constant watering and can be damaged if discharged below 50%.

AGM Batteries 

Absorbent glass mat (AGM) batteries are sealed lead-acid batteries that use fiberglass mats to absorb the electrolyte. They are maintenance-free, leakproof, can handle extreme temperatures, and don’t off-gas. Also, you can discharge them up to 80%.

Lithium-Ion Batteries 

Also called lithium iron phosphate or LiFePO4 batteries, these batteries use the metal lithium in place of lead. They provide more power than the others, charge faster, are lighter, don’t need regular maintenance, last the longest, perform well in all temperatures, and can be discharged without damage. Price-wise, they are the most expensive option.
