Buying Guide: Best RV Battery for Boondocking

Before we jump into the factors that will help pin out the best RV battery for boondocking, we first need to understand what is boondocking and why we need good RV batteries.

Boondocking is also known as free camping, wild camping, or dry camping. This term is most common among RV’ers and it’s used to describe a trip in the wild without any connection to power, water, or sewer.

Since we’re disconnected from all the essential services and amenities one normally needs, it’s also known as ‘Dry Camping’. Hence, if you want to be able to power up any of the appliances inside your RV, you need a power source. This is what RV batteries are usually for.

RV batteries will keep all your electricity-dependent appliances working throughout your trip. A long-lasting, powerful, and reliable Deep Cycle RV Battery will help keep you powered up wherever you are.

Types of Boondocking or Dry Camping

Did you know that there are three different types of Boondocking? Well, there are! This is useful to know to be able to evaluate the best RV battery that will suit you based on the type of boondocking you plan on doing.

First, you need to establish how often you will be off-the-grid and for how long. If you plan on boondocking for long periods at a time you should consider getting a long-lasting battery with high Amp-hours (Ah) capacity that’s also compatible with your solar panel kit.

The Battle Born Deep Cycle Battery and the ExpertPower Lithium-Ion batteries are a great choice for this type of boondocking.

On the other hand, if you’re an occasional boondocker who goes out only a couple of days at a time, you don’t necessarily have to invest in a Lithium-Ion battery. You can opt for deep-cycle AGM or gel batteries instead which cost a lot less than Lithium-Ion batteries.

When we started out, we opted for an AGM house battery which was charged by our alternator when driving. When stopped, we’d charge it with our 120W solar panel. This setup was more than enough to power up our fridge, some lights, and devices.

The Overnight Boondocking

The overnight stay is the simplest type of boondocking that you will come across. This type of boondocking usually refers to parking your RV at a friend’s place for the night, staying at a rest area or even in a Walmart parking lot.

If you are an RV-er, you will surely once in your lifetime, boondock in a Walmart’s parking. Usually, you might want to do that if you’re driving through the city and you want to take a break or if you need to stop due to any adverse weather conditions.

Moochdocking or Staying in a friend’s driveway or front yard for a night is another type of overnight boondocking.

Boondocking on Undeveloped Campsites

Another type of boondocking is staying on an undeveloped campsite which is usually free. This type of boondocking doesn’t have any amenities near the campsite and chances are you’re all alone.

This is the type of self-dependent type of boondocking in which you have to be self-sufficient and rely only on your own resources. You need to make sure you have a plan in place for water, electricity, and other services you may need.

Boondocking on Developed Campsites

This type of boondocking may cost you a small fee for the use of the site. These campsites usually have a specific fee you need to pay to stay per night.

Though you might be able to use a few amenities the campsite has to offer, you might not have any sewer hookups, electricity, or water.

Starter Battery vs Deep Cycle Battery

There are two batteries in an RV as part of the battery management system. One of them is the starting battery that gives a quick and powerful surge to start the engine. The other one is a deep cycle battery which is also called a house battery. The house battery is what you use to power up lights, appliances, and devices in your RV.

Types of RV Deep Cycle Batteries

While reading the above reviews, you would have noticed that there are different types of batteries. There are AGM, Lead-Acid, Lithium-Ion, or Gel Batteries. Which type of RV battery will best suit your setup? Let’s look at the differences between each type.

Lead-Acid Batteries

These batteries are made with lead plates or grids which are submerged in a liquid electrolyte. These are the most common types of batteries used. They are inexpensive, reliable, and durable.

They have a high-performance average and give you high voltages. However, these types of batteries are heavy, and charging them takes time. Furthermore, there’s always the danger of acid leak or overheating.

Lithium-Ion Batteries

Time to revisit 9th Grade Chemistry!  Lithium-Ion Batteries consist of a cathode and an anode that’s usually submerged in an electrolyte (lithium salt solution). The lithium ions swim around two electrodes (cathode and anode).

These batteries are low maintenance and charge quickly. They also have low self-discharge which makes them a great choice for dry camping. On the downside, Lithium-Ion Batteries can be expensive and may not last as long if stored at high temperatures.

AGM Batteries

AGM, or Absorbed Glass Mat, Batteries are lead-acid batteries that are sealed seamlessly. The absorbed Glass Mat as the name suggests is a fiberglass mat that absorbs the entire electrolyte. This prevents any acid leakage from the battery’s casing.

They’re cheaper than Lithium-Ion batteries, they’re renowned for their quick charging and they require no maintenance.

The main disadvantage of lead-acid batteries is that they’re sensitive to overcharging. Their charging capacity also reduces overtime.

Gel Batteries

As the name suggests, the electrolyte in these batteries is in the form of a gel. This type of battery ensures no leaks of the gel or fumes. They can be mounted in any position.

These batteries come fully sealed, require no maintenance, and can withstand high temperatures.

However, they also react poorly to overcharging. Because these batteries use a gel instead of a liquid you need to take them off the charge as soon as it’s complete. This will prevent any voids with the electrolyte which would cause irreversible damage.

Factors To Consider To Choose The Best RV Battery for Boondocking

We will now talk about the various aspects that can help you choose the best RV battery for boondocking. Let’s dive in!

The voltage of the RV Battery

The first and foremost aspect to evaluate to choose the best RV battery for boondocking is its voltage. On the market, you can find 12 volt RV batteries and 6 volt RV batteries. We personally use 12 volt batteries because we find them easier to work with.

The capacity of the RV Battery

There are two things to pay attention to when looking for the best RV batteries for boondocking:

The amp-hours (Ah) of the battery are usually referred to as the charge capacity and watt-hours (Wh) which refers to the battery’s energy capacity.

Amp-hours is the measure of the electrical charge of a battery that will allow a current of one ampere to flow for one hour. You need to look at the amp-hour rating of the battery because it indicates how much electricity you can store and use later.

To check out the amp-hours you require for your RV, calculate the electricity needed by each appliance you plan on operating during your trip. Don’t only measure the electricity they need but also the frequency and the duration of use.

The sum of these calculations will help you to determine the battery capacity that you need.

Charging Versatility of the Battery

Another thing to consider is the charging versatility of the battery’s capacity. If you’re buying RV batteries for boondocking then opt for batteries that can be charged using solar panels, a generator, or battery charger.

In a nutshell, buy batteries that can be charged in different ways to ensure you have enough power for your daily needs no matter where you are.

Optimal Temperature Range

One of the most important factors to consider while looking for the best RV batteries for boondocking is the temperature range they perform the best at.

It’s very important to think about the type of weather conditions you may encounter during your trip. You need to choose RV batteries that can function properly in a wide range of temperatures.

Resistance to vibrations and shocks

While traveling, you will most probably come across many terrains; rocky, bumpy, snowy, smooth, and slippery. This is especially true if you do a lot of off-roading.

These different surfaces may cause the batteries to knock against each other, which in turn may cause them to malfunction due to the impacts.

Thus, it’s important to check if the RV battery is resistant to shocks and vibrations to exclude the possibility of malfunction and damage.

Frequently Asked Questions: RV Batteries for Boondocking

Q.1. 12 volt or 6 volt battery, which is better?

There’s no right or wrong answer. We chose to use 12V batteries because we find them easier to work with and we find them the most suitable for our solar setup.

In saying that, we know some hardcore dry campers who swear by 6V batteries. You can use two of those batteries to make up 12V, but that means you have to buy 2 batteries, and you need to wire them in series.

Furthermore, if you want to upgrade, you will need to buy two more and so on. If you decide to go down that path you need to make sure you have sufficient space and weight capacity to accommodate those batteries.

At the end of the day, it really comes down to how much you plan on camping off-the-grid and your personal preference.

Q2. How Much Power Do I Need While Boondocking?

You need to determine your power requirements for your RV to find out the battery capacity you need. You need to know how many Watt-hours you will use on a daily basis.

For that, you need to make a list of all the things you want to use that require electricity and calculate the number of watt-hours each item uses per day.

In this video, you will learn how to calculate the amount of electricity you will need every day.

Q.3. How to choose the right size of RV Battery for Boondocking?

First, you need to figure out how big of a battery bank you will need as far as amp-hours and determine how many watts you will need for solar panels. Having a properly sized solar setup will make your dry camping experience an enjoyable one, or not.

Here’s how to easily size your RV battery bank and solar set up.

Q4. How to Boondock Safely And Responsibly?

You must keep in mind all the precautionary measures while dry camping. Some of the things that will help you to safely boondock are as follows.

Plan your trip
Make a checklist and write down everything that you might need for the trip. Furthermore, mark locations that might come in handy if you run out of supplies –nearby grocery stores, a hospital, a gas station.

Download Maps
It’s always wise to download maps or apps for your route. This will help you stay on the right path, away from danger. A good app to get is the Boondocking app which shows all the free campsites and maps to get to them.

Find a safe location
To find a safe location, try opting to park your RV in a developed campsite or a Walmart/ truck shops/ Apartment complexes parking lot.
