The RV Battery Types

The RV batteries can be put to multipurpose use for numerous applications such as water-pumps, microwave ovens, blenders, golf-carts, boats, motorhomes, and more. You need to compare the different types according to your rig by checking all the attributes of each for a wise decision.

1. Starting Batteries

These tend to provide short bursts of energy in higher amounts as a number of thin plates maximize the surface area which is exposed to the electrolytes. These are based on cold-cranking amps.

These cannot be used for RV deep cycle battery and for optimal usage you should be aware of the efficiency and use of a great battery.

2. Deep Cycle Batteries

These come in various sizes and large enough to supply more amps to your rig. Power requirements need to be studied beforehand, along with the available space, and installation process.

These are designed for deep discharging, are lead-acid type and work according to specific capacity. Some of them can be used as a starting battery too but if there are lower cranking amps then a larger battery will be required.

These are divided further into different categories:

  1. AGM Deep Cycle RV Batteries

  2. Deep Cycle Gel Batteries

  3. Flooded Lead Acid Deep Cycle Batteries

  4. Lithium-ion Deep Cycle Batteries

3. Dual Purpose Battery/Marine Battery

This type of battery offers supreme starting power along with cycling capabilities. The dual-purpose one can be used with an isolator or a switch system and also functions as a back-up for your deep cycle house battery or a starting battery.

The battery can tackle starting and cycling both but may not be a good cranking battery for start-up than the true cranking ones. Even more, recharges and discharges won’t be handled by it properly. Henceforth, take into account everything before you invest in one.

Some more things to be kept in mind are mentioned below in the buyer’s guide.

How To Pick The Best Rv House Battery?

It becomes extremely important how one chooses an RV house battery. You need to consider and weigh all the options prior to selecting one for your use.


The battery voltage needs to be checked aside from amp-hour rating as this will determine the good vs bad choice.

The starter and deep-cycle batteries have 12-V of direct power while some RV owners combine or connect 6V batteries for building a 12V-system for their equipment.

Though 12-V being one of the most common choices still you need to go with your house requirements.

Shock And Vibration Resistance

You need to check and confirm whether your house battery can tackle constant vibrations and shocks. Sealed designs are something that you should prefer for avoiding any spills or leaks.

These remain sturdy, suitable for tough outdoor conditions, and can be mounted in any position. If you go for a one that is capable enough to handle impacts, vibrations, and shocks, then you will be benefited from saving money as least repairs will have to be dealt with.

AMP-Hour Rating Or Capacity

This also becomes crucial that you check the capacity to get your power needs out of it. The amp-hour rating should be considered as this will indicate the battery capacity to supply a specific current amount over a time period.

For e.g. if the battery is rated at 100 AH, then it is able to supply 100 amps per hour.

If more power is your requirement, then it is right to buy a deep cell battery as this will promisingly serve for a longer period. The weight and battery size also needs to be checked as this will assure you the dimensions that will fit your vehicle.

Even for the right capacity you should look into the specific power requirements on your equipment, as you will need to determine the energy amount on a daily basis.

A battery whose capacity reduces to 50% is still capable of providing power without letting the total capacity down should be your choice. The battery that can be re-charged conveniently with the help of a solar panel, generator, battery charger, or park’s hook-up is a great thing too.

For a few days if your plan is to go off-grid then deep cycle battery will deliver power consistently.

Discharge Depth

When you are in look-out for the best RV House battery then what is its specific power discharge? If selecting a lead-acid type, note that the life-cycle and discharge-depth are interconnected.

Deeper individual cycles tend to provide fewer cycles in general. Pick the battery (deep-cycle) that has a discharge depth which will maximize its life-cycle.

Power By Temperature

This is again very essential to keep in mind: The ability of the battery to supply power at a certain temperature.

Even if the temperatures are low then the battery should be able to provide adequate power and note that there can be freezing temperatures too sometimes.

If the climates are humid or hot then go for a battery that can sustain the performance even if the temperatures are 35-degrees.

Charging Method

What is the battery charging style?

How do you plan to recharge your house battery?

  1. A shore power

  2. A generator

  3. Solar power

A controller can also be used by you as this has the ability to adjust the voltage and current automatically. This in turn keeps your battery protected from any damage. This performs its work regardless of whatever recharging method you use.

When you are trying to charge you can probably choose any of these methods or combine them too. The battery type should be checked so that the recharging goes successfully.

The Final Verdict

After knowing all the battery benefits and usage, take a wise and right decision. All the ones mentioned in the article above are the best brands and you can pick one as per your rig’s power requirements.

Make your adventures, outdoors, and leave your applications more confident, efficient, and hassle-free when they function to deliver their best. We hope you liked our well-informed write-up and this will keep you more satiated and give peaceful long service years by the best RV house battery you select.

Frequently Asked Question's

Q1. How Long Do RV Batteries Last?

Ans. Lifetime of an RV battery depends on how well you maintain it, how often you utilize it, and what kind of battery you have. Lithium ion batteries last for as many as 5,000 charge cycles, whereas deep-cycle batteries only last for 400 or 500.

Q2. What is an ideal size to choose for an RV battery?

Ans. It depends on your application and the need for which you are buying a battery. A 12-V battery will prove sufficient for you for a good camping trip. And for more energy requirements, you can group batteries and wire them in a parallel way.

Q3. How Much Does A Typical RV Battery Cost?

Ans. The cost of your batteries varies wildly with which kind of battery you get.The single, 12-volt, regular wet-cell lead-acid battery may cost several hundred dollars, while lithium battery setups cost thousands. Lithium RV batteries’ extended lifespans mean their cost-effectiveness is actually much better in the long run, so if you can foot the expense upfront, it’s worth it.

Q4. How Many Batteries Does An RV Have?
