You can use trailers to haul camping equipment, lawnmowers, or watercraft. Trailers are available in different shapes and sizes. Moreover, they build them for specific purposes. On the other hand, some people use trailers as RVs, and you can also change them into a more permanent living situation if you add insulation and plumbing.
The Different Types of RV Batteries
What is the best RV battery? To answer this question correctly, it would help to know the different types of RV batteries available. Additionally, you need to understand their various features, including their strengths and weaknesses.
Such knowledge makes selecting the correct battery for your RV effortless. There are four main RV battery types you should know in this sense. They are applicable in different scenarios, as explained below. They include:
Lead-Acid (Flooded)
The flooded lead-acid battery comes with lead plates or grids in a container. They immerse the plates in a liquid electrolyte; hence the name flooded. When you charge the battery fully, the negative plates become lead-antimony while the positive plates are lead dioxide.
The electrolyte becomes concentrated sulfuric acid. On the other hand, when the battery discharges, both plates become lead sulfate through a process known as sulfation. The electrolyte loses much of the sulfuric acid and transforms in the water.
Many RVers like these batteries for various reasons, including:
- Their up-front cost is the lowest
- You can find them everywhere
- You can use them for multiple power needs
- Many people are familiar with the battery type
Its drawbacks include:
- It is heavy and bulky
- Overheats and generates poisonous gas when charging
Gel (Sealed Lead-Acid)
The manufacturers of this battery type attempted to address the challenges of the flooded battery. For instance, these batteries rarely spill because they gelled the electrolyte.
Additionally, you can mount it in any orientation. Moreover, they sealed the batteries so that you can use them in places with minimal ventilation because they don’t off-gas. Wheelchairs and electric scooters use small gel cells.
Why do people love this battery?
- This battery does not flood quickly and does not off-gas when charging
- No maintenance
- It has a higher tolerance to high heat
- It also has low self-discharge
However, it also has some drawbacks, such as:
- Relatively expensive
- It does not stand fast charging
Absorbed Gel Mat (Sealed Lead-Acid)
An Absorbed Gel Mat (AGM) battery is a sealed lead-acid battery, trendy for RV use. In this battery, all the liquid electrolyte in the battery is absorbed into fiberglass mats, making it spill-free.
One of its best attributes is that it can charge faster than flooded batteries. Moreover, most AGM batteries don’t need an equalization charge, apart from Lifeline AGM batteries. You can safely locate them inside your RV, but it is better to put them in a battery box.
The strengths of this battery include:
- It can charge at a relatively higher rate
- It does not require maintenance
- It comes with sealed cells, hence does not off-gas when in use or during charging
- Freezing does not affect it
Its notable weaknesses are:
- It is relatively expensive
- Overcharging can ruin it
Lithium-Ion
These batteries differ significantly from lead-acid batteries. They still have a cathode and anode. However, lithium ions move between the anode and cathode in lithium salts solution.
Its cells are large or small cylinders or soft plastic pouch cells, or plastic rectangular prismatic cells. Many experts consider this battery the best for RV use because it is safe and the most stable. Moreover, it is durable compared to other battery types.
Some strengths of the Lithium-Ion battery include:
- You will not incur maintenance costs
- It has very low power loss at low temperatures
- It is durable (can last 2000-5000 cycles)
- You can store it at a low state-of-charge with no damage
However, it also has its weaknesses, such as:
- It has the highest up-front cost
- You cannot charge it at low temperatures

Our RV Deep Cycle Battery Shopping Guide
The key to finding the best RV battery is understanding certain specifications. You will also need to check a few features to get the correct battery for camper needs. Here is a discussion of the most relevant features you must consider:
Battery Size (CCA vs. AH)
When choosing your battery, you have to decide whether you require a cold cranking amp (CCA) or amp-hour (AH). Most RVers go for CCA batteries because they are more economical. However, they have less endurance.
For instance, if you use your motorhome as a camper van for a week’s holiday, you don’t need a lot of power. In such a case, you can use a lower CCA battery.
A lower CCA battery implies the battery lasts longer and is more economical. Alternatively, if you use your motorhome or camper van for a living, you require a higher CCA battery.
Lifespan
You must consider the RV battery’s lifespan. The lifespan varies depending on how well you look after it. Nonetheless, all batteries have limited lifespans.
One way to ensure you extend your battery’s life is by keeping it charged. Experts recommend keeping an RV battery charged at about 12.7 to 12.9 volts.
Durability
The best RV battery should be durable. That means it should have a strong, solid frame to remain intact. Therefore, before buying a battery, ensure you check the manufacturer’s material and how they put it together.
Materials Mounts are Made of
It is also essential to check the mounting bracket. This is a crucial part of your RV’s battery system. A challenging and durable metal keeps your battery in its position firmly. You can remove some brackets from your old battery and reuse them on your new battery.
Most of the mounts are steel and stainless steel, which act as alternatives to the standard all-steel versions. Steel corrodes over time, making it susceptible to rust, especially when exposed to humidity or water.
Stainless steel is an excellent alternative because it doesn’t trust easily. Moreover, it lasts longer than regular steel variants.
Amperage Hours
It will help if you select a battery with the largest Amp-hours to ensure it performs its job for extended periods. Therefore, ensure you know the difference between Ah and CCA rating means. Amp-hours refer to the amount of energy stored within each RV battery.
Rated Capacity
Here, you will be looking at Amp Hours. They say that the higher the Amp Hours, the better. However, you should find out how many Amp Hours you need. The amount of power you need in your RV will help you answer this question.
Nonetheless, an Amp Hour rating of 100 Ah is sufficient. Five amps will be available for 20 hours or 10 amps for 10 hours of uninterrupted use. Therefore, if your RV has many applications, you should get a battery with a high Amp rating of over 200.
Alternatively, you can also add more batteries and connect them in series. For instance, you can connect three batteries with 100 Ah in series to have 300 Amp Hours. This allows you to use more applications simultaneously for a more extended period.
Charging Method
There are several methods you can use to charge RV batteries. Standard charging methods include alternator charging, generator, solar panels, and shore power using a converter.
It is critical to note that you need to charge your camper battery regularly. In this regard, the charging method and frequency of charging can significantly affect your battery’s life.
The common reasons for RV battery failure are undercharging and overcharging. When you repeatedly overcharge your battery, it will lead to water loss and plate corrosion. On the other hand, undercharging can also cause the plates to harden into crystals.
Voltage
The standard car battery voltage is 12 volts. You can also find a 12 volt RV battery, while others are 6 volts. Usually, you will need a 12-volt battery to power your electric application. On the other hand, the 6-volt RV battery is ideal for providing alternative wiring to your batteries together in parallel and series.
Suppose you settle for the 6-volt battery; you will undoubtedly need two batteries connected in parallel to get 12 volts. Some 6-volt RV batteries offer higher amps at a lower cost than a 12-volt RV battery. Moreover, they are more durable and have thicker plates.

FAQs on RV Deep Cycle Batteries
How Do I Pick A Compatible Battery Charger?
When looking for a charger for the battery for an RV trailer, please go for one that provides the amperage you need per your battery’s specifications. It is critical to ensure your battery works at its optimal level.
In this regard, don’t use the correct voltage only; instead, also use a charger offering enough amps. Fortunately, all chargers come with an amperage rating. Therefore, ensure you check the amp rating of the camper battery you have. Typically, a battery’s amp rating should be equal to or greater than its amp rating.
What Is A Battery Kit?
An RV battery kit comprises a set of lead-acid automobile batteries. It also includes a set of clamps, cables, and connecting hardware.
The manufacturers design the kit to offer the power supply for RVers who use RVs powered primarily by electricity. Additionally, you can use the materials to convert AC power from the generator to DC power. You can also use the battery kits to store the solar panels or wind generators’ electrical energy.
Is A Deep Cycle Battery Better Than Other Battery Types?
For RVs, deep cycle batteries are better than other RV battery types. The deep cycle battery differs from the standard car batteries because it stores energy in a bigger area. Additionally, it has thick plates allowing more surface contact, preventing the chemical reaction from stopping quickly.
Besides that, deep-cycle batteries also offer longer-lasting power than cars’ cranking batteries. They also offer sufficient power to handle big electrical loads such as refrigerators and motors. Furthermore, they don’t go dead quickly like the standard car batteries, which only start the car engine once a day.
How Does An RV Battery Work?
RVs usually have two or more batteries on board. In an ideal situation, you need a separate battery to act as your car’s ignition battery. Such a battery requires excellent cranking power or the cold cranking amp (CCA) that is enough to start the vehicle even during severely cold conditions.
The other batteries will provide power for all the other applications in the RV. For instance, you will use it for your RVs lighting system, solar panels, entertainment system, and inboard appliances. This is why people sometimes refer to them as house batteries.
Since you will not use these batteries to start an engine, cold cranking amp is irrelevant. However, they are helpful if present in the battery to act as a spare if your main battery goes bad.
RV batteries come with a wide range of configurations because they offer a reliable power source for a more extended period. In this sense, the best batteries for a travel trailer should have deep-cycle capability. Additionally, they should have Amp Hours (Ah) instead of a CCA rating for starter batteries.
Therefore, if you have numerous inboard appliances and plan long travels where you will have minimal access to an electric power source, you need more batteries. You will also have to set the batteries up in series to allow you to use them simultaneously for different inboard applications.
Key Summary
An excellent deep cycle RV battery has specific attributes that buyers must consider. For instance, you should check their durability, size, and mount materials.
Besides that, you can determine what is the best deep cycle battery for an RV by checking the amperage hours and rated capacity. Furthermore, you must consider the voltage and charging methods.
Above all, you need to consider the electrical power needs for your RV and your camping adventures. For instance, you need the best RV battery for dry camping if you go to a place without an electric power source.
