People who aren’t RV enthusiasts or who have just bought an RV for the first time may not realize that these vehicles don’t just have one battery—they have multiple ones. One of them is to turn the engine over to start it, but the other one is responsible for supplying power to the cabin of the vehicle. And since this second battery is used in this way, it’s often referred to as an RV house battery.

Although an RV needs both types of batteries, it can be difficult to find a house battery suitable for an RV. That’s why we did some research and found what we feel are the ten best RV batteries currently available. The following batteries are suitable for use in an RV and are designed to give the user the power they need when they need it.

RV Battery Buying Guide

As we briefly stated in our introduction, there are actually two different types of RV batteries. There are batteries that are used to start the vehicle, and there are batteries which are used to power various electrical systems. Therefore, it’s important to choose the one that fits your needs and your RV. If in doubt, the RV’s instruction manual or website is the final say to what type of battery can be used. With that in mind, below are some suggestions for buying an RV battery.

Step One: Read Your RV’s Manual

The first step to buying an RV battery is to read your RV’s instruction manual fully. The manual lays out what type of battery is needed for the RV and helps to lay out the parameters that the battery needs to have for it to perform correctly in the RV. It’s also a good idea to read all of the safety precautions and warnings listed in your manual.

Step Two: Choose a Battery Type

When it comes to RV batteries, there are basically three different types available: conventional electrolyte batteries, gel batteries, and AGM batteries. Each of these different battery types has their own pros and cons as we’ve detailed below.

Conventional Electrolyte Batteries: These are the batteries that are commonly found in most automotive applications. They are created using lead plates and an electrolyte solution. They’re designed to give a decent initial burst of power but aren’t very good for delivering consistent power over time. They also tend to require quite a bit of care to ensure that their terminals don’t become corroded.

Absorbed Glass Mat Batteries (AGM): These batteries are the type of battery that is used almost as much as conventional batteries. They are made using an absorbed glass mat and an electrolyte solution located in between the plates of the battery. They are designed to last longer than conventional batteries and are designed to deliver high Amp bursts when needed. And since it’s self-contained, there is less maintenance than with conventional batteries. These batteries can also usually be mounted in any position.

Gel Batteries: These types of batteries aren’t used as often as conventional or AGM batteries. They are made using an electrolyte that’s suspended in a gel matrix instead of floating in a liquid solution like a conventional battery. These batteries can perform in hotter temperatures than most other batteries and also discharge slowly. Unfortunately, these batteries often require to be charged in a particular way, so if an RV user wants to use these types of batteries without damaging it, then they are going to have to buy a special adapter that enables them to properly charge it.

Step Three: Choose a High Maximum Reserve Capacity

It’s also important to check the reserve capacity of the battery to make sure that it’s capable of delivering the results you need it to deliver. The maximum reserve capacity lets the user know how long the battery is capable of delivering power to their electronics. Choosing the one with the highest possible Max Reserve Capacity will ensure that your RV has the power it needs. Alternately, you can also check the Amp-hours to determine if the power has the required power necessary for the job at hand.
