What to Know Before Buying RV Battery for Boondocking


Choosing the right RV battery is crucial for boondocking because it’s what keeps your appliances running in an uninhabited area. Here’s what you should learn before you go shopping for an RV battery.

The Different Types Of RV Batteries

The first thing that you need to know is the different battery types to help you choose the right one. Each has its components, usage, and life cycle.

  • Starting Batteries

This type is your typical car battery that cranks power for starting engines. It tries to produce a large power burst in an instant, so you can get the vehicle running with just a single turn of a key. Compared to deep-cycle RV batteries, they have thinner and softer plates to generate more power.

  • Deep Cycle Batteries

These batteries are what supply power to your RV appliances like lights and TV. Instead of short bursts of power, they provide steady current over long durations. They also tend to be more robust than their starting counterparts.

Deep-cycle batteries have undergone many developments over the years. Here are the subclassifications of deep-cycle models.

  • Flooded Lead-Acid Batteries

A flooded lead acid battery is the most budget-friendly option. However, it needs to be mounted upright to prevent the free-moving electrolytes from leaking out of the caps. Electrolytes can go low over time, so ensure to add distilled water every two weeks or so.

  • Absorbent Glass Mat (AGM) Batteries

Also known as a type of sealed lead acid battery, an AGM battery is an improvement from the flooded versions. These sealed lead acid batteries are leak-proof, so they can be mounted in any position. They also have a low self-discharge rate with a shock-resistant construction, but a more expensive price tag.

  • Gel Batteries

These gel batteries use a gel paste to replace the electrolyte inside the case. Just like AGM, these batteries are sealed and leak-free. They also have stronger battery terminals with a slower discharge rate, but they can be overcharged.

  • Lithium-Ion Batteries or LiFePO4

Lithium RV batteries are a great upgrade to lead acid batteries. They use lithium-iron phosphate, so they don’t leak out like a lead acid battery does with sulfuric acid. Thanks to lithium-ion technology, these batteries offer more efficiency and power capacity at a more lightweight construction.

The only downside is the high price upfront, but it can be evened out with its long lifespan.

Benefits And Drawbacks Of RV Batteries For Boondocking

Many camper owners cannot stay in an RV park all the time. If you’re one of them, you’ll need a battery for boondocking because it helps power your camper appliances and devices in the most remote areas.

Without it, you can’t use your lights or fridge when going off-grid for days. These batteries can store plenty of electricity, so you won’t have to rely on an electric outlet.

The only drawback is proper maintenance and care. You need to use the correct charger and keep the connections tight and corrosion-free. If you’re using a flooded or wet cell battery, it requires a lot of work as you need to keep the cap secure to prevent leaks.

What To Look For In A Good RV Battery For Boondocking

The best batteries for RV boondocking should be reliable and long-lasting. Here’s a guide to features to consider when buying an RV battery.

  • Amp Hours Rating: This feature can tell the battery’s capacity. The best RV batteries have 100 amp hours rating at least to power most essential appliances like a small fridge, lights, and TV.

Keep in mind that the size is directly proportional to the Ah rating, so choose one that’s big enough to run all your devices.

  • 6-volt vs 12-volt: Many RV owners prefer a 6V RV battery for boondocking because it’s lighter and has higher amp hours. However, they’re expensive. The 12-volt models are more cost-effective, but you need to use multiple batteries if you want to increase the capacity, which can create a bulky setup.
  • Lifespan: You constantly charge RV batteries, so you want your battery for dry camping to last for many cycles. The best models, especially the lithium ones, can work for up to 10 years with proper maintenance.

To protect the battery from damage, look for a BMS feature that disconnects power each time it senses any irregularity.

What Size Battery Do I Need for Boondocking?


Your choice of battery size depends on your needs. If you own a small RV, a group 24 battery is the ideal choice for boondocking. To power more devices, choose a group 29 or 31 or 6-volt battery.

How Much Battery Power for Boondocking Will I Need?

A capacity of 100 amp hours is enough to power the basic electrical devices in your RV for a day. If you want to be certain, you can make a simple calculation using the formula watts=volts x amps.

To get the total Ah, divide the watt rating of each device by 120 volts AC and multiply the quotient by 10 and the number of hours used. Let’s say you’re computing the total amps for a water heater and a microwave that uses 1500 and 500 watts, respectively.

Water heater= 1500/120= 12.5; 12.5 x 10 x 0.5 hour usage= 62.5 amp hours

Microwave= 500/120=4.16; 4.16 x 10 x 0.5 hour usage=20.8 amp hours


Total = 83.3 amp hours

In the example above, a 100Ah battery will suffice.

How to Set Up an RV Battery for Boondocking?

For a travel trailer, the best battery setup is with a lithium battery and solar panels. You’ll want a reliable boondocking battery setup because it will provide all the power you need to operate everything in the rig.

First, install solar panels on your RV roof. You might need to drill on the roof and apply a flexible sealant.

If you have some old batteries, pull them out and replace them with new lithium ones. Use one battery or multiple batteries in a series for more power.

How Long Will the RV Battery Last Boondocking?

Depending on how many appliances you use, 12-volt RV batteries for boondocking can go for two days max. To extend battery life, turn off devices when they’re not in use. Choose energy-efficient appliances to consume less power.

Furthermore, if you are interested in other products that support your RV power systems, don’t forget to visit the following reviews:
