The best RV batteries for boondocking

Some people may prefer to enjoy their RV hooked up to water, electricity, and sewer services, but that isn’t for everyone. Others feel the call of the wild and want to experience nature close up without being limited by where they can find the right hook-ups. Boondocking can be an incredible delight, and it doesn’t require “roughing it” as some may think! This is where your RV battery comes in handy, letting you use all the functionalities of your RV without being hooked up to campsite amenities. 

But which one is right for you? The best RV battery for boondocking depends on your RV and your personal preferences, but some are certainly better than others. In this article, we’ll break down the different types of batteries and which one might be best for your rig.

What kind of battery will you need?

Finding the right RV battery for you isn’t just a matter of going out and buying the most expensive and powerful one. It depends heavily on the type of trip you’re taking, where you’ll be boondocking, and for how long. Here are a few things to consider about what you want out of your battery before you dive in:

Battery voltage

RV batteries are divided into two voltage categories: 6-volt and 12-volt

Your RV will require 12-volt power, but this can be achieved by linking two 6-volt batteries in a series. 6-volt batteries are pretty inexpensive and last longer than 12-volt batteries, and you can even hook up pairs of other batteries in parallel for extra power if you’d like.

12-volt batteries, on the other hand, are even cheaper but tend to not last as long. You can save money with a 12-volt if you plan on boondocking for a short amount of time, but it’s usually worth springing for a pair of 6-volt batteries.

Battery capacity

Different RVs have different sets of appliances and devices, which means they also have different energy requirements. It’s important to know how much energy your RV will need to do all the things you want it to do before you buy a battery. A good rule of thumb is to add up the energy requirements for all the appliances and devices that you want to use in your RV, then get a battery with a capacity that’s double this total number. 

How you’ll use the battery

You might just use your RV battery to power your devices and kitchen appliances, but in some instances, people use batteries to start their RV’s engine as well. This will require a special dual-purpose battery.

If you want to use it to start your engine, the battery’s cranking amps are an important measurement to know. This gauges how much power your battery can supply to start up your engine.

Temperature range

RV batteries each have their own optimal temperature ranges that they thrive in. If they’re used outside this range, they may not perform as well. To ensure you get the right battery, be aware of the estimated temperatures you’ll experience wherever you’re headed beforehand so that you can buy accordingly.


You’ll likely be driving over some rough and varied terrain while boondocking, so you want a battery that can withstand a bumpy ride. Some batteries have spill-over problems, making them a hazard to have if they’re going to shake and vibrate a lot while you drive. Getting a strong, durable battery is always a safer bet.


Another must-have boondocking amenity for many is a functional toilet. Make sure you have a place to go— wherever you go— by reading about the best RV toilets.
