Top 5 Best RV Battery 2022 - Deep Cycle RV Battery for Dry Camping

Are you RV Owner? One of the key things that you need to ensure is that your vehicle is okay and will not break down. Take for instance your RV batteries.

You need to have good batteries that are in good condition since they play an important role in the reliability of your RV. If they are not in good condition, then you might find yourself stranded in the middle of nowhere with an RV that won't start.

Buying a battery for your RV can be a confusing task. There are so many battery options out there and each manufacturer tries to convince you their products are better than the rest. Which one is right? That's where we come in!

Choosing the right RV battery is an important decision that should not be taken lightly, and our comprehensive guide will help you make sure you get it right.

How We Choose RV Deep Cycle Batteries

There are many factors that go into choosing the right battery for your RV. One of the most important things to consider is what type of battery will work best with your vehicle. There are two main battery types: deep cycle and starting. Deep cycle batteries are designed to be discharged regularly, whereas starting batteries are designed to provide quick bursts of power and then recharge.

If you have an older motorhome with a generator, chances are you have a deep cycle battery in it already. If not, you may want to add one or upgrade the current one in place if it's too old or doesn't hold a charge well anymore. For newer RVs without generators, a regular starting battery can be used instead but will need charging more often than if it were being used as a backup power source.

Another factor to consider is whether or not your RV has an onboard charger or solar panels installed, or if these features are planned down the road.

In the world of RVing, there are many different options for batteries. We have compiled a list of 5 favorite RV batteries for the money. Our goal is to help you find the right battery for your needs.

Best RV Battery FAQs


Lithium-Iron Phosphate batteries are the most expensive, but they also last longer than any other type. A Lithium-Iron Phosphate battery can last up to 10 years, which is more than double that of a lead-acid battery. They also have a very low self-discharge rate which means that they don't need to be recharged as often as other types of batteries.


The biggest reason why lithium batteries are better for RVs is because they're more durable than lead-acid batteries. Lithium batteries can withstand extreme temperatures better than any other type of battery on the market.

This makes them perfect for use in an RV since the temperature in your vehicle can fluctuate significantly over the course of a day or week. There's no need to worry about your lithium battery failing if you drive through an area with extreme heat or cold.


The first thing you should look for in an RV battery is cold cranking amps (CCA). The higher the CCA, the more powerful and durable the battery will be. The next thing to look for is the reserve capacity (RC) rating. This measures how much energy can be stored in a battery after being fully charged. The higher the RC rating, the longer your RV will run between charges.

A third important factor to consider is whether or not you want AGM or flooded batteries. AGMs use glass mat separators between plates to hold acid instead of using a liquid electrolyte solution. This makes them less likely to leak when they're damaged, but they tend to be more expensive than regular flooded lead-acid batteries.


They have several advantages over other types of rechargeable batteries, including high energy density, light weight and long life.

However, they also have a few disadvantages that you should consider before using them in your next project.

The first disadvantage of lithium-ion batteries is their price. They are more expensive than other types and can be even more so if you buy them with a battery management system (BMS). Lithium-ion batteries also require special battery chargers to charge your batteries because they use different charging voltages than other types of rechargeable batteries.

Another disadvantage of lithium-ion batteries is that they can explode if punctured or overcharged. While this usually only happens with improperly designed or damaged cells in an assembly, it's something to keep in mind when handling these batteries.


If your RV battery is less than two years old, then the first thing to check is its charging system (alternator). A faulty alternator will not charge the battery properly, causing it to die prematurely. To test this theory, turn off all electrical appliances and accessories in your RV for several hours (with no one using any lights).

Then turn on all electrical appliances and accessories at once, including lights, water pump, air conditioner, motor, and possibly the microwave oven. If there are no unusual noises coming from the engine compartment (like a clicking sound) after several minutes of this activity, then the charging system must be faulty and needs to be checked by an RV technician or mechanic before proceeding further with this diagnosis.
