Do you have an RV? Do you know what the best RV house batteries are? If you’ve answered yes, this post will help you find the best RV house battery to make your camping or life off the grid easier.

Traveling with your buddies or family in your RV allows you to experience the world and explore new places. Campsites make it easier to provide power to your RV and enjoy the beautiful surroundings.

However, what if you are traveling off the grid? Your RV needs power when you are traveling away from the campsites or during emergencies.

Those who don’t have much knowledge about RV systems might be perplexed to find out that a recreational vehicle requires two batteries. The first battery is commonly known as the standard starter battery.

It is used to supply a brief but powerful jolt to the engine to help it start. In contrast, the second RV battery has many names, such as the deep-cycle battery, coach battery, RV house battery, etc.

An RV house battery expels minimal energy at once but lasts for extended periods. These batteries are responsible for delivering power to your recreational vehicle’s cabin.

They supply power to your RV’s kitchen appliances, lights, and other applications when the RV is parked at a campsite or isn’t running.

A well-designed RV house battery will last far longer as compared to a starter battery, which means you don’t have to replace one very often.

However, VMAXSLR 125 AGM RV house battery is not as affordable as other smaller AGM batteries.

But it offers a high amp-hour storage capacity.

Key Features

  • Heavy-duty.

5. Universal Power Group 12V 100Ah VRLA Battery

If you are looking for an AGM RV house battery that you can use for dry camping, off-the-grid travels, or solar setups, then look no further than the Universal power group 12V 100Ah solar wind AGM SLA battery.

The battery can produce enough power to keep running your 12V appliances without having to recharge as often as you would with some other batteries.

If you connect a pair of these batteries in parallel, you will have up to 200 amp hours to work with. Larger RV house batteries like this one are an excellent pick because they eliminate the risk of getting RV batteries so low that you start to damage them.

Regardless of what AGM battery you have, you should not run it down under 50%. Anything lower than that will help sulphuric crystals to build upon internal panels.

It will reduce your battery’s ability to hold the charge for longer periods. UPG 12V 100Ah AGM battery is larger than a standard RV battery, so you might need a bigger box to keep the battery safe if your storage is outside your recreational vehicle.

Like any other AGM battery, it is also vibration and shock resistant, which means you can mount it as you desire.

Moreover, the battery is also a good pick for both hold and cold temperatures than traditional flooded lead-acid batteries.

All in all, the UPG 12V 100Ah AGM RV house battery is a top pick for any solar or RV setup.

I highly recommend this battery for people who live off the grid, boondock, or dry camp more often.

Key Features

  • Affordable.
  • Easy to install.
  • Maintenance-free.
  • Multipurpose.
  • AGM/SLA.

  • The battery should be your top pick if you live off the grid or dry camp/boondock more often.
  • It is maintenance-free, which means you don’t have to monitor the battery more often to keep it in its peak condition.
  • Since the RV house battery is shock and vibration resistant, you can mount it in any position you like.
  • Because of its large size, the battery is quite heavy. Also, it may not fit well in standard battery storage boxes.


Before I discuss the best RV house batteries, you should know what parameters must be considered when buying one.

Factors to Consider Before Buying a RV House Battery

1. Battery Material Types

When hunting for the best RV house battery, one of the chief parameters you should consider is the battery’s material.

Currently, lithium is the most popular and top-rated option. Though the upfront price is a bit more than other material types, it lasts far longer than other cheap materials in the long run.

Moreover, you should also know that lithium batteries do not perform well when the temperature is too cold.

Sealed Battery

Another popular RV battery material is Absorbed Glass Mat or AGM. AGM batteries are lead-acid, maintenance-free batteries. They use an absorbent glass mat to absorb sulphuric acid.

Unlike lithium batteries, AGM batteries can work exceptionally well, even when the temperature is too harsh. Moreover, AGM batteries also have a longer lifespan than their counterparts, lead-acid batteries.

Lead-acid batteries are the least expensive option for an RV house battery, but they require the user to top off distilled water in the battery cells every two or three months.

However, you can charge these batteries numerous times without reducing their performance.

These batteries sometimes have a shorter lifespan than lithium or AGM batteries.

2. Battery Size

Battery size is another deciding parameter that you should take into account when looking for the best RV house battery.

These batteries generally come in two different sizes. One is 6V batteries, and the other is a 12V battery.

You can use both of these sizes in the grouping, whether in a series or wired in parallel.

However, 6V batteries are armed with thicker plates that give them a greater cycling capacity to extend their life. But, they do need a pair of 6V batteries wired in a series to obtain the standard 12V RV applications.

3. Maximum Capacity and Discharge Rate

The maximum discharge rate of RV house batteries is measured in volts. You may find it abbreviated as “V” in the product description.

In contrast, a house battery’s capacity is measured in amps (amp hours), abbreviated as Ah.

It means the more amp-hours a battery advertises, the greater the maximum capacity of the battery.

The maximum discharge rate of a house battery is crucial as it determines the number of RV appliances you can use at the same time.

Thus, your RV house battery is advertised to offer a maximum discharge rate of 12V; it can comfortably support twice as much demand as a 6V battery.

Most house batteries amplify the standard voltage of the battery by up to 10x so that it can power 120V appliances present in your vehicle.

A 6V battery could be the difference between requiring to be economized on appliance use and being allowed to operate an electric kettle and an oven simultaneously.

On the flip side, not all RVers will need a house battery to simultaneously deliver a handful of appliances. If you are considering using your RV alone, you can do it with a lower maximum discharge rate. But, there is never a scenario in which lower battery capacity is preferable for RV house batteries.

4. Self-Discharge Rate

Always remember that the maximum discharge rate and self-discharge rate are two different terms. The self-discharge rate means the speed at which an RV house battery loses power when operating any application. It is determined by battery chemistry.

In this regard, lithium batteries are the ones that have the lowest self-discharge rate. They take years to fully discharge without any use.

The self-discharge rating of an RV house battery is critical because your vehicle will not be drawing power from the RV battery all the time.

However, when you want to supply some power from the battery, you want the house battery to have enough power to supply your applications.

RV house batteries with a higher self-discharge rate are more likely to be un-functional when you have not used your vehicle for extended periods.

In comparison, batteries with low self-discharge rates are reliable and have enough charge to power your appliances when you need them the most.

5. Voltage

Before you invest in an RV house battery or any other RV battery, make sure to consider its voltage rating.

The voltage rating of an RV battery should perfectly match the voltage rating of your recreational vehicle.

4. Warranty

The main reason you invest in an RV house battery rather than investing in a standard battery is that these batteries last for longer periods and deliver a high discharge cycle rate.

However, if you also want to get a battery that lasts for many years, then make sure to consider its warranty, so you don’t have to replace it for many years.

Wrapping Up

There you have it – the five best RV house batteries. When buying an RV house battery, there are many factors that you should take into account.

Also, make sure to invest in a battery that perfectly fits your power needs.

I sincerely believe that the above RV battery reviews guide will help you find the best RV house battery to enjoy your dry camping or off-the-grid living.
