Traveling across the country in an RV is one of the most liberating and immersive experiences one can have. Today, campsites and travel centers have become much more versatile than before with swanky power hookups. But, sometimes you might have to rely on your RV as a power source. In order to make the most of your travels and also not get stuck anywhere, you want a long-lasting and high-quality battery that won’t let you down. The best deep cycle batteries for RV setup are a godsend if you want to stay at a remote location or are in-between campsites. Whether you’re looking for great versatility, durability, reliability, or value, you have a ton of choices. Basically, a deep-cycle battery is designed to use most of its capacity via regular deep discharge. Thus, it provides sustained power over a longer time period until it’s as much as 80 percent discharged.
If you’re an outdoors person and enjoy traveling on unknown roads and routes, then the best RV batteries deep cycle ones are the way to do it. The best RV battery setup with such batteries is perfect for everything from overnight to cross-country trips, powering your vehicle reliably. To that end, here are the 13 best deep cycle batteries for RV setup out there.
How To Choose The Best Deep Cycle Batteries for RV?
When it comes to RV traveling, there are so many essentials you’re going to require, right from the Best RV Covers to the Best Coolers For Road Trips. That said, a battery is equally important, as you might be in some remote corner of the region and don’t want to be stranded at such a time. So, what should you look for when it comes to the best RV batteries of the deep cycle kind? Read on.
Power and endurance
You might be used to starter batteries expelling short bursts of high power for getting things up and running. Deep-cycle batteries, a.k.a. travel trailer batteries, expel consistent and steady power over longer periods of time. These sustainable batteries charge appliances and power devices and keep the lights on long after even your vehicle calls it a day. Also, a good-quality deep cycle battery should last longer than a starter battery, which means you won’t have to replace it often.
Reserve capacity and amp-hours
In order to buy a good battery, you needn’t be an engineer, but you should know about the “more is better” approach when it comes to comparing reserve capacities and amp-hours. Basically, the greater the number, the more powerful and longer the battery. When it comes to the amp-hours approach, for instance, a 100AH battery lasts longer than a 35AH battery. On the other hand, if you opt for the reserve capacity approach, then a 120-minute reserve capacity is obviously better than a 60-minute reserve capacity. All said you must stick with either method and not both. After all, you can’t really compare one battery’s reserve capacity to another battery’s amp-hours.
Yet another crucial factor is the depth of discharge (DoD), which is the percentage of the battery that has been discharged as compared to the battery’s overall power capacity. The rule of thumb is that the more often that a battery charges and discharges, the shorter its lifespan is. Thus, good deep cycle batteries have a greater discharge depth (up to as much as 80 percent), thus keeping them in good shape.
Types of batteries
Basically, there are two kinds of best RV batteries deep cycle ones – absorbed glass mat (AGM) batteries and wet cell or “flooded” batteries. In the end, the choice boils down to maintenance-free and a maintenance-full configuration. For instance, AGM batteries are non-hazardous, spill-proof, and sealed, and thus don’t require maintenance, Wet cell batteries, on the other hand, require occasional refilling since they lose the acid and water solution with each use. Again, certain wet-cell batteries can be refilled by users, while others require professional maintenance service. Also, recharging AGM batteries is much faster as compared to wet cell batteries. However, they are overall prone to more damage and decreased performance, and offer less protection over time.

How Long Do RV Batteries Last?
When they’re taken care of properly, including not overcharging them, deep cycle RV batteries last anywhere between 5 and 7 years. In fact, deep cycle batteries can be run down and recharged many times over. With no overuse and timely maintenance, they should be able to power your RV for many years to come, some even going up to a decade or more!
How Many Batteries Do I Need For My RV?
Depending on how big your RV is, you might need up to 6-7 batteries, or maybe even more in order to run all of your systems. Usually, even smaller RVs with not many bells and whistles require at least 2 batteries for powering all your creature comforts such as the kitchen, bathroom, and lights. As an alternative, you can even daisy-chain the batteries together to transform them into a larger cell that can deliver more reliable and effective power.
