What to Look for When Buying the Best RV Battery for Dry Camping (A Buying Guide)

The best RV batteries are ones that can supply your needs and power the appliance that you need. Let’s see our buying guide below.


The capacity of a battery is measured in the amp. And it refers to the amount of electricity that a battery can provide per hour. So what you have to do is to gauge the total energy that all your appliances will need to run.

It’s also best to add a bit more to the total energy consumption so you have a little leeway. It can also prevent deep charges that can shorten the lifespan of your batteries.

Types of batteries

There are four main types of batteries for RV. You have to consider what each type of battery has to offer, its pros and cons. We have dedicated a section in the article to discuss the different types of batteries.

Cranking amps

Cranking amps are the energy needed to start your RV engine. Though if you will power just the appliances and not your RV, this is of the least concern.

The battery will show cold-cranking amps and regular cranking amps. Cold-cranking amps are the energy provided at 0 degrees Fahrenheit while regular cranking amps measure the energy of current at 0-32 degrees Fahrenheit. 

Discharge cycles

This indicates how the battery is depleted. You have to be able to manage this as it can affect the longevity of your batteries. You also must not exceed the recommended depth of discharge.


Not all RV batteries can be used in extreme temperatures. Some may function well but will not be able to tolerate very cold temperatures. So check for the battery’s optimal ranges and compare it to the range temperature of the parking space.


Boondocking involves traveling through rugged trains. So you must choose a battery

that will be able to withstand the shaking, wobbling, and rocky road hills. It must be able to bear vibrations.  

Types of Batteries

Here are four main types of RV batteries and what the pros are.

Lithium-ion batteries

There are several types of lithium-ion batteries. But the most popularly used for boondocking is lithium-ion phosphate batteries.

The main advantage of these batteries is that they are very reliable and suitable for full-time boondocking. They are also the safest to use long-term.

The downside is that they have a higher upfront cost. 

Gel batteries

These are made from viscous gel electrolytes. They are safer than lead-acid batteries. And they do not give off fumes or gases and are completely sealed off.

They can also be used in very high temperatures, thus they are resistant to harsh environments. And gel batteries relatively are zero maintenance. 

The downside is, they tend to have an oversensitivity to charging. And they also have a higher upfront cost. And some brands may require a specific charging profile.
