Best RV Battery for Boondocking Buying Guide

Factors to consider when buying an RV battery for boondocking

As you’ll have already noticed from our reviews above, there’s a lot of technical jargon that comes into play when selecting an RV suitable for boondocking.

To help make the decision process easier, in this section you’ll find a breakdown of the top features that you’ll want to take into consideration before making a purchase. 

Voltage

During your search for the best RV battery for boondocking, there are two main types of battery voltages that you’re going to come across.

The first are batteries with a 6-volt capacity, and the second is batteries with a 12-volt capacity. Most commonly, 6-volt batteries often tend to use a much thicker plate than batteries with a 12 volt.

Though they have a lower power capacity, they’re often much more durable and long-lasting with a lower price point - not to mention being more lightweight! This makes them a popular choice for RV users that like to boondock.

On the other hand, batteries with a 12-volt capacity are another option for you to consider. They’re more powerful than 6-volt batteries, however, they tend to run out of charge quickly, which means that you’ll probably find yourself having to frequently top the battery up than if you were using a 6 volt one.

Regardless of this, their higher power capacity makes them another popular choice for boondockers, as it means that they can power appliances with a higher amperage requirement. 

Weight

As you’ll be traveling, you’ll want to try and avoid overly heavy batteries, as this will only make it more difficult to transport, move around and store.

No matter what, the battery you choose is likely to weigh at least 40 pounds or more, but if possible, we strongly recommend avoiding RV batteries that weigh over 80 pounds. 

In addition to this, we also recommend keeping an eye out for ‘convenience’ features that will make transportation a little easier.

For example, nowadays, many RV battery manufacturers will add a handle to the tops of their batteries so that the battery can be carried around more safely. 

Durability

The next factor you should consider is durability.

Sure, it’s important to make sure that the battery you choose will offer powerful, efficient performance, but if it hasn’t been properly built to withstand a few knocks and bumps that will inevitably come along with travel, you’ll find yourself having to replace it a lot sooner than you would have liked. 

We recommend looking for batteries that consist of a heavy-duty design and feature exteriors that have been coated with some kind of weather-resistant material, like polypropylene. This will help to extend the service life. 

The types of batteries suitable for boondocking

You’ll also have to decide which kind of battery you’d like.

The most common types of RV batteries suitable for boondocking are lead-acid batteries, AMG (absorbed glass mat batteries), lithium-ion batteries, and gel batteries.

Keep reading to learn more about each one. 

Lead-Acid Batteries

This is by far the most popular kind of battery due to it being reliable, affordable, and able to withstand overcharging.

Lead-acid batteries are constructed from lead plates and grids that are carefully immersed inside a liquid electrolyte. They are able to offer high voltages and can be left on a trickle charge if needed.

The main downside to these types of batteries is that they tend to be heavy.

AGM Batteries 

Absorbed Glass Mat batteries are sealed lead-acid batteries that have been a popular choice for people that boondock since they were first created in the 1970s.

Unlike lead-acid batteries, in AGM batteries all of the liquid electrolyte used has been soaked into fiberglass mats, which helps to make them more leak-proof.

Another plus point of AGM batteries is that they require no maintenance and have at least a 95% charging efficiency. The main downside of AGM batteries is that they are sensitive to overcharging. 

Gel Batteries

Gel batteries are widely considered to be one of the safest battery options, as they are made with viscous gel electrolyte. This kind of electrolyte cannot leak as easily as the liquid electrolyte used in the other types, and they don’t give off any harmful gases during charging either.

Though this battery requires no maintenance, they often take quite a long time to fully charge. 

Lithium-Ion Batteries

The last kind of battery most commonly used for RV boondocking is lithium-ion batteries. These types of batteries feature lithium ions that move between both the cathode and anode and are suspended in a lithium salt solution.

They’re stable, reliable, and long-lasting, and thanks to their high energy density, this type of battery is capable of offering high charge voltage rates.

For this reason, these batteries are popular with travelers who need to charge high amperage appliances. The main downside of this kind of battery is that they are the most expensive type on the market. 

Frequently Asked Questions

How long will an RV battery last boondocking?

Fully charged, your battery should last you around 2-3 days before needing to be recharged. 

How do I charge my RV boondocking battery?

Before you set off on your trip, your battery can be charged by being plugged into a power outlet that has either a 30 or a 50 amp connection.

However, while boondocking, you will need to use either a generator or a solar charger.
