Overview

What Is An RV Deep Cycle Battery?

A deep cycle battery is an efficient power source for full-time RV-ing. This power source can run onboard electronics and appliances. It is worth noting that RV batteries do not generate power. Rather, they imply house electric power.

AGM Battery

Besides, it can provide the rig with a continuous longer-lasting current. Deep cycle batteries can house a large amount of power, enabling them to operate for a long time.

Hence, the best deep cycle battery for RV has to offer a consistent amount of current. Plus, it should provide support for basic equipment like TVs, coffee makers, air conditioners, refrigerators, microwaves, and water pumps.

Besides, these batts can charge in the range of 50% – 70% of the capacity. RV deep cycle batteries boast thicker plates to have fewer surface areas.

How Do RV Batteries Work?

A camper battery normally needs consistent discharging and recharging. When you have to charge the cell, the battery bank will likely collect the power to start the cycle again. But it will require less energy, unlike a normal starting cell.

Initially, you have to know what several voltage basics are. Commonly, a deep cycle cell runs at 12-voltage direct current cycle electrical energy. The power can provide enough energy for a small electrical system and other appliances inside the RV.

Then most of the batteries operate on an amp-hour mechanism. Thus, they can have a single amp within an hour. That said, there are various types of RV deep cycle cells. Each of which works in different ways.

Types Of RV Deep Cycle Batteries

RV deep-cycle cells are available in four types: Absorbed Glass Mat, Flooded Lead Acid, Lithium-Ion, and Gel Sealed. Each type has its pros and cons.

It is imperative to understand the features of each battery type and make a comparison among these types to see which kind will suit you best. Briefly, flooded lead-acid cells have been the most common batteries for RVs.

Though they require a vented location and frequent maintenance, they are still the most efficient batteries today. Meanwhile, absorbed glass mat batteries are the best choice for those who seek products with low maintenance.

These batteries are tougher and tend to be more expensive than flooded lead-acid cells. The priciest battery is the gel sealed model with sensitive charging. Still, it is a perfect option if you need high resistance against temperature and vibrations, which is a blessing for RVs enduring various conditions.

And if you value a lightweight battery, the lithium-ion cell is your answer. It is great power storage that can provide constant energy. For comparison, you can check out the following table.

Absorbent Glass Mat Batteries Flooded Lead Acid Batteries Lithium-Ion Batteries Gel Batteries
Venting No venting Venting No venting No venting
Resistance Features Highly vibration resistant Cannot tolerate large vibration levels Well handle with extreme vibrations, temperature, shock Resist extreme vibrations and temperatures
Maintenance No maintenance Regular maintenance Very little, even no maintenance No regular maintenance
Setup Able to be set up in all directions Set up in the upright position Versatile attachment in directions Able to be set up in all directions
Price More expensive Affordable Expensive Priciest

Absorbent Glass Mat (AGM)

AGM deep cycle RV batteries require less maintenance. The key drawback of this type of battery is that it’s quite expensive. In return, it’s much stronger and tougher than other variations. In fact, it’s a kind of lead-acid cell in which the fiberglass mat wicks away the electrolyte.

This mat raises the surface ground to keep ample electrolytes on the batteries. It offers 80% discharge depth and a charging time that is faster by five times than others.

As the internal resistance level is lower than that of flooded cells, the AGM RV batteries can handle high temperatures and self-discharge slower. AGM deep cycle batteries are suitable for RVs with equipment or appliances that demand higher power.

Another plus point of this battery type is that it is less vulnerable to sulfation. Accordingly, you can utilize this battery again, even if it does not work for one year as long as you maintain it.

We love this battery as it allows the installment in any orientation, even at low temperatures. As a result, it’s the better battery choice if you go to locations with cold climates. Besides, thanks to its sandwich construction, it can highly resist vibrations.

Unlike flooded lead-acid (FLA) batteries, the absorbent glass mat cells are quite sensitive to overcharging, so they need a high voltage for charging. Still, they outweigh the FLAs when it comes to ventilation.

These batteries do not produce hydrogen or gas during charging. So you can rest assured about safety and ventilation when using AGM batteries.

Flooded Lead Acid (FLA)

FLA batteries have electrolyte fluid, letting the plate be completely submerged, hence the name “wet cells”. By discharging the battery, the plates transform to lead sulfate and then dilute the electrolyte.

Accordingly, housing electricity into the cell or charging prompts sulfate coating off the plats and returns into the electrolyte. In the same way, it produces oxygen and hydrogen gas. Water molecules found in the electrolyte will take apart from the electrolysis.

Unlike gel and AGM batteries, vented FLA batteries allow the gas to release into the air. It is worth mentioning that hydrogen gas can be explored. Hence, battery boxes and compartments need vents so that the gas can escape.

In terms of power output, FLA cells have about 20% loss on average. In other words, you can draw 80W-hours for each 100W-hours into this cell. The minus point of this battery type is that it does not tolerate many vibrations.

So you will need to regularly maintain this cell by equalizing charges, distilled water filling, and cleaning the terminals. Moreover, it requires regular discharging, cycling, and recharging, especially water during the summer.

Similarly, it needs off-season charging, meaning you must install it in the upright position. The plus point is that this kind of battery features hydrogen venting. As a result, it can cope with overcharging well compared to the gel and AGM counterparts.

Besides, it comes with the lowest cost for each amp-hour. They are even more affordable than AGM and gel batteries.

Lithium-Ion

In several aspects, lithium-ion deep cycle RV cells outperform other types. They utilize nano-scale phosphate cathode materials so that they can offer great electrochemical performance yet with low resistance.

It delivers exceptional thermal stability, a long life cycle, and a high current rating. They are also common power storage for various outdoor tools due to their lightweight design. This cell type can function well in extreme heat and cold.

It can work at a temperature of up to 149 degrees F safely. As it boasts versatile mounting, you can set up the cell in all directions with no compromising power flow. Lithium-ion cells are expensive, yet you can save up more thanks to their efficiency in the long term.

Gel Sealed Batteries

This type of battery utilizes electrolytes to thwart it from spilling. Even if it utilizes fiberglass matting, you can attach it to the side with ease. Like the FLAT RV deep cycle batteries, gel cells can transform easily.

That said, the gelled electrolyte is extremely vicious. The minus point of gel batts is their gas recombination when charging at a slow rate. As a result, the charging time will be much longer than that of AGM and FLA batts.

On the bright side, gel batteries don’t need regular maintenance. They can even last longer than AGM cells. Besides, this type of cell comes with narrow charging profiles. Improper charging can form gas pockets on the plates, forcing the electrolyte away from them.

In return, the capacity of the battery will decrease. If you are not familiar with resolving chargers and battery issues, gel batts are not suitable for you. Moreover, it is also the priciest RV deep cycle cell around.

That said, if you seek tough batteries to handle extreme temperatures and vibrations, you can consider gel models. One more thing, solar power applications and gel batteries are great pairings.

Benefits Of RV Batteries

Eco-Friendly

You do not need to regularly alter an RV deep cycle cell as it’s built for long-time use. You will not need to purchase from time to time, contributing to nature conservation.

The cell can be maintained for several years, so it can help reduce waste released to the environment. Moreover, you can also depend less on the use of fossil fuels.

Heavy-Duty Performance

The deep cycle batteries are much more durable than conventional or starter batteries. The starter batteries can provide a high-current burst of power in a short time to start up the engine of your car, while this deep cycle type offers constant power for your RV’s appliances.

Moreover, you can charge them for the long term. Also, they work stably rather than just starting the engine of the car.

Efficiency

This type of battery can produce consistent power so that it can deliver exceptional efficiency. Plus, you can utilize more of a source of alternative energy than those run by fossil fuel.
