How to Choose the Best RV Deep Cycle Battery

Why is choosing the highest quality deep cycle battery for your RV so important? Let’s put it this way: your deep cycle battery can make or break your RV adventure. It’s the battery that powers your appliances and electronics. It’s your “workhorse” power bank that delivers sustained power over long periods of time.

Obviously, you want a reliable battery that keeps your lights on and your stress levels off. After all, you planned your camping getaway to relax, not to amp up your anxiety.

Best RV Deep Cycle Battery Checklist

Here’s what to look for when choosing a deep cycle battery for your RV:

  • Low Self-Discharge Rate

  • Long Lifetime

  • Environmentally Friendly

  • Durable

  • Maintenance-Free

  • Reliable

  • High Cycle Rating

If your current RV battery doesn’t check off all the boxes above, it’s time to make an upgrade.

Upgrade Your Deep Cycle RV Battery

Luckily, there is a battery that checks off all the boxes. Ionic lithium is the newest battery type on the market, but it’s quickly taking the RV world by storm.

Why? Lithium LiFePO4 batteries innovate and improve in areas where lead acid, gel, and AGM batteries fall short. This is why we can confidently say they’re the best RV deep cycle batteries available today.

Lithium RV Batteries Self-Discharge Slower

Most RV batteries are like leaky faucets. They release a constant flow of energy, even when they’re not powering any appliances. Take lead acid batteries, for example. They self-discharge at a rate of 30% or more per month.

Is there any way to stop this from happening? Unfortunately, no. It’s not as easy as calling a plumber to fix a leak. There’s no way to stop a traditional RV battery from self-discharging. In hotter climates, this issue is even worse.

So what’s the best way to avoid packing the fam into the camper, only to have to cancel the trip because of a discharged battery? Simple: choose a battery with a low self-discharge rate. A lithium RV battery will discharge only 2% per month, so it’s always ready to go when you are.

Lithium RV Batteries Last Longer

The best RV deep cycle battery is the one that ultimately saves you time, gas, and money. You might think that lithium batteries are the most expensive of the bunch. But when you do the math, you’ll discover that lithium RV batteries cost less in the long run. Here’s why:

  • Lithium RV batteries last 4x-5x longer than traditional lead acid batteries.

  • Lithium LiFePO4 batteries are rated to last 20,000 shallow cycles, or 10 years.

  • They can exceed 2,000 full cycles with 80% capacity left. That’s 5 times better than lead acid.

  • Lithium is less susceptible to damage, even in high or low temperatures. This is an incredible advantage when camping or boondocking in extreme weather.

  • These batteries weigh less than any other battery type (50% less than lead acid), saving you gas.

  • Lithium batteries don’t need electrolyte replacements or special care. Unlike traditional batteries, their lifetime doesn’t depend on how well you “pamper” them.

What does this mean cost wise? You won’t need to replace your batteries as often, so your lithium RV batteries will end up saving you money.

More Advantages of Lithium RV Batteries

Here’s another reason why lithium is the best RV deep cycle battery. When you’re out and about in your recreational vehicle, the last thing you want is battery failure. Even more so when you’re far away from campgrounds! Lithium batteries are the most reliable batteries on today’s market.

Why? Because of their chemistry. They’re made with non-toxic lithium iron phosphate. Unlike traditional batteries, they aren’t susceptible to damage caused by overcharging, or discharging past 50% capacity. They don’t need any maintenance either.

But beyond that, there are a few other reasons why the best RV deep cycle battery for camping is ionic lithium:

Advantages for the Environment

What do all RVers have in common? Their love for the outdoors. Many will do most anything to go green and respect mother nature, even if that means going without creature comforts.

But you don’t have to stop using your favorite gadgets just because you’d rather not run a noisy generator or hook up to the grid. Simply switch to lithium!

Pair with
Solar Setups

Lithium LiFePO4 batteries are great when paired with solar setups. They will produce consistent output for your appliances even when discharged below 50%.

Keep Nature

Lithium batteries don’t contain nasty chemicals that harm the environment. Unlike lead acid batteries, they won’t spew toxic leaks. You can store them anywhere, even indoors. And when they finally reach the end of their long life, you can bring them to your local recycling center.

Advantages for Boondocking/Dry Camping

Boondocking and dry camping involve going off grid. So you want a battery you can count on to keep your lights on, especially during extended trips.

Lithium is the best RV deep cycle battery for off-grid adventures because it offers unbeatable reliability, including in extreme weather:

  • Lithium batteries can operate at 70°C (158 °F) without life degradation.

  • They can operate in -30°C (-22 °F) with slight performance degradation. They won’t freeze.

  • Lithium deep cycle batteries work well with solar panel setups, and conserve and use power efficiently during inclement weather.

Customer Reviews

Robert Willis

"I bought 3 of these 125AH Ionic batteries with 2 for my 24v trolling motor and one for my cranking and electronics. After 3 seven hour tournaments they are about 62% & 75% full still! That's with two 9 inch fish finders, Panoptics, livewell, and lights running all night! Best battery and support out there! And the phone app is great for seeing what's going on with the batteries!"

"Lithium Hub batteries and customer service are second to none. Their products continue to deliver everyday. I spend 9 hours 3 days a week on the water and my batteries have never gone below 50 percent. It is amazing. I have used interstate, optima and north state batteries and never had this kind of performance."

"Pretty happy so far. Using on a mobility scooter. Nice to always know the charge level of the batteries. Running 2 in series with a 24v charger that came with scooter. Seems to work ok."
