How to Choose the Best RV Battery for You

RV house batteries may look a lot like car or starter batteries, but they’re quite different. While car batteries, or a starting battery, are designed to provide a single large charge to start a vehicle, RV batteries offer a longer, more consistent electric current to power onboard appliances and electronics.

From coffee machines and microwave ovens to TVs, phone chargers, and everything in between, motorhome batteries can be used to power virtually everything in your rig and any electronics you may want to take with you on the road.

Known as deep cycle batteries, they provide a stable source of power for off-grid living, camping, and exploration.

Why You Need an RV Battery

RV deep cycle batteries are great for powering your RV appliances and electronics off-grid. If you’re at a campground or park with hookups, they can also provide you with a backup power supply should a bad storm hit and knock the power out.

Since a camper trailer battery is designed for repeated charging and discharging, they’re also excellent for storing solar energy, making them great companions for solar panels. Some are even dual-purpose, allowing them to both start up your RV and provide long-lasting deep cycle power.

RV batteries can pretty much do it all. Having one will allow you to keep you and your family comfortable wherever your adventures may take you.

Types of RV Batteries

Similar to marine batteries, all batteries for RVs are deep cycle. However, there are a few different types of RV deep cycle batteries out there to choose from.

Lead Acid Wet Cell Deep Cycle RV Battery Diagram

Flooded/Wet RV Batteries

Flooded or wet type feature plates that are fully submerged in electrolyte fluid. They’re the cheapest type and with proper care can last a long time.

However, flooded/wet batteries usually require more maintenance and need to be well-ventilated to prevent oxygen and hydrogen gas buildup.

Absorbed Glass Mat (AGM) Battery diagram

AGM RV Batteries 

AGM stands for “absorbed glass mat.” Unlike flooded/wet models, AGM technology is sealed and produces virtually zero gas. This also means there’s no spillage or maintenance needed.

Batteries of this type charge very quickly and are better for storage than flooded/wet batteries. They also perform better in low temperatures, making them a good option for campers north of the Mason-Dixon Line.

Gel RV Batteries

Gel batteries predate AGM batteries for RV use. With this type, the electrolyte is mixed with silica, creating a gel.

Like an AGM RV battery, gel batteries are sealed and can’t spill. However, they have a noticeably slower charge and are generally much more finicky to deal with.

Lithium-Ion RV Batteries

Lithium-ion batteries are lightweight, charge efficiently, and deliver reliable performance. They’re also more expensive, but they can be mounted in a number of ways and operate well in both high and low temperatures.

Since they use lithium iron phosphate or LiFePO4, they’re also safe, maintenance-free, and have a long life cycle despite delivering a constant discharge.

Features and Factors to Consider When Choosing the Best Travel Trailer Battery for You

In addition to types of batteries, there are several other features and factors to take into account, such as:

Capacity

Battery capacity is rated in ampere-hours, abbreviated to Ah. The greater the Ah capacity, the more amps it can deliver, which is always a good thing. For example, a 12v RV battery rated for 100Ah can produce 100 amps for an hour, or conversely, one amp for 100 hours.

When determining your energy needs, it’s best to play it safe and go with a few more amps than you think you’ll need. Ultimately, you want to be able to power everything you think you’ll need in a day without your recreational vehicle batteries dropping below 60 or 50 percent of their capacity.

Ideally, you would be able to recharge them through solar power, a campground electrical hookup, or a generator to have them ready for use the next day. If you plan on being off-grid without a solar panel setup for any length of time, you’ll need to select batteries with the largest capacity possible.

Unfortunately, more power usually comes at a cost. In this case, it’s size and weight. The bigger the battery, the more room you need to connect and store it.

Voltage

The typical voltage for both starter and deep cycle batteries is 12 volt. While some campers will take cheaper 6 volt batteries and string them together with a second to get the 12V they need, we don’t recommend this. Sticking to a 12v deep cycle RV battery will serve you best.

Discharge Depth

Usually expressed as a percentage, the discharge depth indicates how much of a battery has been used or discharged. With lead-acid batteries, the extent of discharge correlates to the batteries life cycle.

In most cases, the deeper your battery cycles, the fewer cycles it will give. Therefore, you should follow the recommended discharge depth to optimize the batteries operating life.

Charging

When on the hunt for batteries for your RV, you’ll also need to consider how you’ll be charging them. Will you be using solar power, an electrical hookup, or a generator?

If you like, you can combine each of these charging methods, but you’ll need a smart charger or charge controller. This device will deliver the perfect charge based on your battery type. It will also protect your battery by automatically adjusting the voltage and current.

Unless you like twiddling your thumbs and need an excuse for a little extra wood carving time, you want batteries with a quick charging time. Less time charging means less time collecting solar energy, less money spent on gas for the gennie, and less time on a concrete slab hooked up to an electrical plug.

Operating Temperature

Different camper batteries operate better than others at extreme temperatures, both high and low. So, if you plan on camping in Colorado for some wintertime skiing or Arizona for some summertime adventure, you need to make sure your battery will keep providing the amount of power you want when you need it most.

Shock and Vibration Resistance

Lastly, you need to consider whether or not a battery will be able to handle the constant vibrations and shocks of your rig and the road. A well-constructed product with good shock resistance will keep on performing without a hitch when the road gets bumpy.

When shopping for RV batteries, look for models with a sealed design. It’s also a good idea to pick one you can mount in any position without spills or leaks. However, the most important thing is that its housing is sturdy and secure.
