RV appliances and gadgets require batteries, and you can choose between AGM and golf cart batteries. These batteries power everything from light fixtures to fridges. You can also use them as chassis batteries to start the motorhome’s engine.
But what’s the difference between AGM vs golf cart batteries for RV, and which one is right for your RV? If you don’t know their benefits, drawbacks, and uses, you won’t enjoy the trip. A faulty battery can lead to your RV’s appliances working less efficiently or even malfunctioning.
Here, we’ll take a closer look at the difference between these two types of batteries to help you enjoy your RVing without any unexpected power outages.
What are AGM Batteries and Their Uses for RV?
AGM batteries are a type of deep cycle battery that is often used in RV applications. They are made with Absorbent Glass Mat (AGM) separators, which are made of fibrous material that absorbs and contains the electrolyte.
This design helps to prevent the release of corrosive gases and makes AGM batteries safer to use than traditional lead-acid batteries. They are much more vibration-resistant, which makes them perfect for use in RVs that travel over rough terrain.
You can recharge and discharge them much faster, which is very useful if you need your motorhome to be powered up immediately. It will also save you the hassle of replacing batteries on the road.
An AGM battery typically has a longer lifespan than a traditional lead acid battery and can be used in a wider range of temperature extremes. This house battery also has a higher power density, meaning it can provide more power per unit of weight to the motorhome.
Many high-performance applications use these batteries, such as golf carts, marine applications, UPS systems, race cars, and motorcycles. They are often used in applications where space is limited, such as in caravans and travel trailers.
Due to their higher power density and longer service life, they are also becoming increasingly popular in hybrid and electric vehicles. When choosing an AGM battery for your RV, pay attention to the battery’s capacity and Cold Cranking Amps (CCA).
The battery capacity indicates the amount of power stored, and the CCA rating indicates how much power the battery can deliver at cold temperatures.
What are The Benefits and Drawbacks of Using AGM Batteries in an RV?
One type of RV battery that has become increasingly popular in recent years is the AGM battery. Before using this acid battery, you should be aware of its pros and cons.
Benefits of AGM batteries:
AGM batteries offer a number of benefits, including:
Available on 6v and 12V Batteries:
An AGM battery is available in both 6v and 12v varieties. This flexibility makes it easy to find just what you need. With a higher energy density, this RV house battery can deliver more power than 6 volt ones.
These batteries are often used in high-performance applications such as power tools, electric vehicles, and marine applications. Compared with a 6 volt cell, a 12 volt battery costs more.
Many people who own an RV or a golf car opt for a 6v gel battery because it is more affordable than 12v ones. If you are looking for a 12v power output, you will need to connect two batteries in parallel.
Spill-Proof:
RVs often use AGM batteries because they are spill-proof. Because of this, if the battery is accidentally tipped over, the electrolyte will not leak out and cause a fire or other damage to the RV.
The gel is held in place by a glass mat, which prevents it from moving around inside the battery. AGM batteries are sealed, so there is no way for air to enter and cause the electrolyte to expand and burst out of the battery. Unless a problem occurs with the charging system, these batteries will not release gas unless they have been overcharged.
There’s no need to worry about toxic fumes or sulfation build-up inside the vehicle. There is no need to protect the battery terminals from objects that falls on them. It is better for you and your family’s health.
High Power Output:
AGM batteries are able to provide a consistently high level of power, even when under heavy load. These qualities make them ideal for RV accessories and appliances. The low internal resistance of these batteries suits RVs, where space is often limited.
With thin plates, you can expose more surface area to the electrolyte, increasing the rate of electron exchange. The result is a higher discharge rate and increased power output when used – a crucial aspect when running large appliances or electronics.
Slow Discharge Rate:
One of the benefits of AGM batteries is that they discharge very slowly when idle. Thus, they can last for long periods of time without needing to be recharged. AGM batteries have a very low self-discharge rate.
It means that they retain their charge for longer periods of time than other types of batteries. They are designed to be deep cycle batteries. Since they are rechargeable, they can be discharged and recharged repeatedly without causing any damage.
Charge Faster:
Many RVers like to use AGM batteries because they charge faster. The low internal resistance is also the reason that they can be charged quickly. When the battery dies, it can mean being left in the dark. With an AGM battery, you can get your battery back to full power.
AGM batteries usually take 5-6 hours to charge. Some RV batteries can be fully charged in less than two hours, which is ideal for RVers who are often on the go. By choosing a fast-charging AGM battery, RVers can enjoy the benefits of a high-quality battery without sitting in the dark.
Higher Capacity and Longer Life:
The higher capacity of AGM batteries means that they can power RV appliances and accessories longer before needing to be recharged. RVers can use AGM batteries for a longer period before they need to replace them, which saves them money in the long run.
This is especially beneficial for those who like to travel for extended periods of time or who live in their RVs full-time. With these RV house batteries, you can be sure your batteries won’t die on you when you are out in the middle of nowhere.
As AGM batteries feature sealed construction, there is no risk of leakage or spillage. They contain thicker plates, which increases their durability and resistance to external damage.
Unlike other batteries, these ones can withstand deep discharge cycles without losing capacity. In contrast to lead-acid batteries, these batteries are reusable without having to be replaced frequently. Combining both, these factors make AGM batteries a wise choice for those who need long-lasting power storage.
Vibration Resistant:
The AGM separator is made of a very porous, fibrous material that soaks up and holds the electrolyte in close contact with the lead plates. This construction helps to prevent the formation of damaging sulfate crystals on the plates, and it also makes the battery more resistant to vibration.
You can take your camper off the beaten path without worrying that your battery will be damaged. So it helps to avoid losing power when you’re out of cell service.
Maintenance Free:
An AGM RV battery is maintenance-free, meaning that you don’t have to continually check the level of charge or top off the battery with water. You don’t need to add water or other chemicals to the battery. As it does not emit gasses while operating, it does not require venting.
They’re designed to withstand higher temperatures, so no worries about them overcharging in hot weather. These batteries are less likely to sulfate, eliminating premature failure. You can spend more time enjoying your trip and less time worrying about it.
Drawbacks of AGM batteries:
You may be wondering if there are any disadvantages to using them.
More Expensive:
AGM batteries tend to be more expensive than traditional lead-acid batteries. They are made from higher quality materials. They contain 99.99% pure lead.
Because AGM batteries are made with thicker plates, they are heavier and more difficult to produce. AGM batteries use a different electrolyte solution, which is more expensive to manufacture. As a result, AGM batteries typically cost 20-30% more than lead-acid batteries.
Heavy Weight and Need Special Chargers:
AGM batteries are also much heavier, making them difficult to install and replace. This can also be a problem for RVers because it adds weight to the RV, which can negatively impact gas mileage.
Most RVs come equipped with one or more AGM batteries. These batteries require a special charger in order to function properly and can be difficult to find. Without the proper charger, the batteries will not hold a charge and will eventually fail. This can create problems for RVers, as they may be left without power in an emergency situation.
Sensitive to Undercharge or Overcharge:
They are sensitive to overcharging and undercharging. If an AGM battery is overcharged, it can damage. If it is undercharged, it will not provide enough power to run the RV’s equipment. RV owners who use AGM batteries must be very careful to monitor their charging levels and make sure that their batteries are not being overcharged or undercharged.
AGM batteries start with a reduced capacity and slowly lose even more capacity as they age. This can make it difficult to rely on AGM batteries for long-term power needs.
What are Golf Cart Batteries and Their Uses for RV?
A golf cart battery is a deep cycle battery that has a higher capacity than a standard automotive battery. It is designed to be discharged and recharged multiple times.
These batteries will power a variety of RV appliances, including lights, fans, and television. They can also be used to run the RV’s engine starter, making them an essential part of any RVing adventure. Golf cart batteries typically have a lifespan of four to six years.
They are usually six volts or 12 volts. A 12-volt battery has six cells connected in series, and each cell produces two volts for a total of 12. The capacity of a golf cart battery is measured in amp hours (Ah).
The Ah rating is the number of amps that can be drawn from a fully charged battery for 20 hours before the voltage falls below 10.8 volts. For example, a 100 Ah golf cart battery can provide five amps for 20 hours (100 Ah / 20 hours = 5 amps).
What are The Benefits and Drawbacks of Golf Cart Batteries in an RV?
Golf cart batteries have been gaining popularity as a power source for RVs in recent years. They are relatively inexpensive, easy to find, and offer a number of advantages over traditional lead-acid batteries.
There are also some potential drawbacks to using golf cart batteries in an RV. Before making a decision, it is important to weigh the pros and cons of this battery.
The Benefits of Golf Cart Batteries in an RV:
Longer Battery Life:
Golf cart batteries are designed to withstand deep discharge cycles, meaning they can handle being regularly drained and recharged without losing capacity. On regular use, this battery can power 8-10 hours per charge.
Some golf cart batteries can provide up to 12 hours of power per charge, making them ideal for extended camping trips. You have to stop your rig sometime while driving because they are designed to use a deep discharge and recharge frequently. By properly maintaining them, you even get to use them for six to ten years.
Small Size and Low Cost:
These batteries are much smaller than AGM batteries, but they still provide plenty of power for RVers. They are typically used in golf carts and other small vehicles. For RVers, these batteries are a good alternative because they are compact. They are easier to transport and install.
Their lighter weight also doesn’t adversely affect gas mileage as much as AGM batteries. It is a significant advantage for RVers who wish to save money on fuel.
Compared with AGM batteries, they are much less expensive, making them a more viable option for RV owners. You can find golf cart batteries at most auto parts retailers and online stores, and they are often used in golf carts as replacement batteries.
Have 6v and 12v Models:
The majority of golf carts have a 6-volt golf cart battery, but you may also find them with a 12-volt for them. A 6v golf cart battery is typically used for smaller RVs, as they are not as powerful as 12v batteries.
They are still a good choice for those who want to save money on their purchase. It’s also easier to find a 6 volt battery if you need to replace the battery in your motorhome.
12v golf cart batteries are more powerful than 6v batteries and are better suited for larger RVs. They are also more expensive, but if you plan on using your RV frequently, they may be worth the investment. These batteries also last longer than 6v batteries, so you won’t need to swap them as often.
Frequently Charged and Discharged:
A golf cart battery can be charged and discharged more frequently for RV because it can help to improve the power and performance of your RV. When you are driving your RV, the battery is constantly being charged and discharged.
This battery is made up of two main parts: the anode and the cathode. The anode is made up of lead, and the cathode has lead dioxide. When the battery is charging, the anode gives off electrons, which flow through the electrolyte to the cathode.
The electrons then reduce the lead dioxide to lead, storing energy in the process. When it is discharged, the flow of energy is reversed, and the stored energy is released. They are not subject to corrosion like other metals.
You can charge and discharge them more frequently without damaging the battery. This makes them ideal for use in RVs, where they can be used to power lights, appliances, and other electronic devices.
The Drawbacks of Golf Cart Batteries in an RV:
Need Maintenance and Short Range:
A golf cart battery needs to be regularly cleaned and charged in order to keep it in good condition. Failing to do so can lead to a shortened lifespan and reduced performance. Golf cart batteries should be stored in a cool, dry place when not in use.
It is composed of lead and lead oxide plates submerged in an electrolyte solution of water and sulfuric acid. When the battery is discharged, the lead plates are oxidized, and when it is recharged, the lead oxide plates are reduced back to lead.
This process of oxidation and reduction causes a build-up of lead sulfate on the plates, which can eventually prevent the battery from holding a charge.
You should regularly maintain your golf cart battery to prevent this. This includes periodically cleaning the terminals and posts, as well as adding water to the cells to keep the electrolyte level topped off.
Typically, a golf cart battery is not typically suitable for long-distance travel in an RV for a few reasons. Due to their design, they are not suitable for continuous use long-term. When used for long-distance travel, they may not provide the same level of performance as other types of batteries.
Need 2 Batteries to Get 12v:
Typically, they have only 6 volts of battery power. For most RV electronics to work, two golf cart batteries must be connected together in order to generate 12 volts. You cannot connect an odd number of batteries. Therefore, if you have three or five 6v batteries, they won’t work.
In this case, you would either need to get rid of one of the batteries or replace it with a 12v battery. While using two batteries may seem like a hassle, it is actually a very efficient way to power your RV. You can also extend the life of your batteries by using two 6-volt batteries instead of one 12 volt battery.
AGM vs Golf Cart Batteries for RV: Which are Right For You?
When it comes to RV batteries, there are two main types: AGM (absorbed glass mat) and golf cart. AGM batteries are more expensive, but they offer a variety of advantages over golf cart batteries.
For one, AGM batteries have sealed systems, meaning that they’re maintenance-free and won’t leak if they’re damaged. Additionally, AGM batteries can be installed in any position, making them ideal for RVs.
Golf cart batteries, on the other hand, tend to be cheaper and can be deep cycled (discharging and recharging). Golf cart batteries require more maintenance than AGM batteries and can only be installed in a certain position.
As a result, golf cart batteries are not as well-suited for RVs as AGM batteries. But if your budget is tight or you don’t mind doing some extra maintenance, golf cart batteries are a good option. Keep the battery fully charged and keep it clean to prevent damage. Now it is yours whether you want to go with AGM or golf cart batteries for your RV.
