While RV camping is much more enjoyable than staying in your average tent, it’s also less pleasant to spend a night in the dark. The brightness of an RV battery can keep you occupied and entertained by providing power on-demand when you need it. But how long will an RV battery give you while camping? It all depends on what activity you’re up to. Some activities will require only brief use of the battery lights, whereas other activities might exhaust your capacity over the course of multiple hours. There is no one answer – test this yourself!

Campers and parkers have long relied on the benefits that an RV battery can provide – even when parked. Whether it’s powering a refrigerator or a full-sized TV, batteries are essential for RVs. But what happens when you take your RV camping?

RV batteries typically offer increased run times while plugged into an AC adapter, but what about running the AC without the adapter? How long will an RV battery last while camping without electricity?

According to manufacturers, most RV batteries will last between four and eight hours without AC power. Extended runs of up to 12 hours are possible with careful usage and a fully charged battery. However, in harsh environments, like Proving Grounds at Nevada’s Great Basin National Park or in hot climates, batteries may only last two or three hours before needing recharging.

Dos and Don’ts for Camping with a Battery

Camping with an RV battery is a great way to enjoy the outdoors. However, there are a few things you should keep in mind to make sure your battery lasts as long as possible.

Here are some dos and don’ts for camping with an RV battery:

DO make sure your RV is properly maintained and fully charged before setting out on your trip. You’ll save time and trouble if you take care of your RV before you hit the road.

DON’T neglect to charge your battery before you head out on your camping trip. A fully charged battery will give you plenty of power while camping.

DO use a heavy-duty converter/regulator if you’re using an electric motor while camping. A converter will help increase your RV’s battery life by increasing the amp draw from the electrical system.

DON’T overload your RV’s electrical system – it’s not necessary and can actually cause damage to your battery. Limit your use of lights, electronics, and appliances when camping in order to conserve power.

If You Have to Turn Off Your Battery

If you find yourself having to turn off your RV battery more than usual, it could be because of one of the following factors:

  • A weak battery
  • Trying to run your RV with the generator when the battery is already weak.
  • Running low on gas and not plugging in your RVThe first thing you should do is check your battery’s condition. If it seems weak, replace it with a new one.
  • Next, try to conserve energy by turning off unnecessary appliances when possible and only using the generator when necessary.
  • Finally, make sure you’re refueling your RV regularly so that you’re not running out of power while in the middle of nowhere.

How Do I Know if My Battery Is Dying Before I Leave the Campsite

Ideally, you will want to avoid bringing a battery-powered RV into a campground if it is showing signs of being nearing the end of its life. Keep in mind that the power outlets at most campgrounds are typically extremely limited in both amperage and voltage, potentially causing your battery to suffer from a shortened lifespan. Additionally, always keep an eye on your battery’s condition – if it appears to be struggling even after a full charge, it may be time to make a quick exit.

Where to Buy Rechargeable Batteries on the Road?

Options for purchasing rechargeable batteries for your RV may be limited, but there are a few places to look.

Here’s a list of some of the best options, with prices and average battery life provided.

  • Amazon – $14.99 per battery
  • Walmart – $17.98 per battery
  • Sam’s Club – $21.97 per battery
  • Costco – $29.99 per battery

Each has its own strengths and weaknesses, which you’ll want to take into account when making your purchase. For example, Walmart has 88 percent more reviews than Amazon but only has an eight-hour average battery life rating compared to Amazon’s 12-hour rating. Sam’s Club also falls in the middle with an eight-hour rating and 92 percent more reviews, but their price is higher than both Costco and Walmart.

While it may be best to comparison shop for rechargeable batteries before hitting the road, knowing the average lifespan of a rechargeable lithium-ion battery may be helpful too. According to Battery University, the typical RV battery will last up to 12 months before it needs to be replaced


An RV battery will last up to 10-12 years if it is kept fully charged and only needs to be recharged every 3-6 months depending on how often the RV is used. Proper care of the battery should include keeping it clean and free from corrosion, as well as following manufacturer guidelines for charging and storage.
