What to Look for When Buying an RV Battery
Choosing the best RV battery setup is essential in making sure that your vehicle continues to run as efficiently as you have hoped for. To boost your chance of finding the most appropriate one for your vehicle, here are some aspects you should carefully consider during the time when you are still selecting the right products:
Capacity – The RV battery’s capacity can actually be measured or rated in Ah, which means Ampere hours. Such indicates the specified amount of current the battery is capable of delivering over a certain period of time. For instance, a battery model with a 100Ah capacity is capable of delivering 100A for one hour.
A high-capacity battery is ideal because it instantly means that it has the ability to store more power and serving longer. The higher, the better. However, you also have to check the weight and the size of the battery. Remember that you will be needing some room for storing your batteries in your vehicle.
When figuring out the ideal capacity for your vehicle, it would be best to compute your specific energy requirements. Provide some adjustments by adding a bit of extra or room. Also, make it a point to determine the amount of power you will need daily.
You should then choose a battery, which can supply such power without going down to sixty to fifty percent of its total capacity. The good news is that it is possible for you to recharge the battery based on how much power you consumed with the help of a generator, solar power, or a campground or park’s electric hookup.
However, if you plan to go off-grid for several days without any chance for a recharge, you should look for a battery, which can supply the power that you need without the risk of it depleting.
The depth of discharge – Another aspect you have to examine closely during your search for the high quality RV battery is the depth of discharge. It is usually expressed in the form of percentage and shows the specific amount of power discharged by the battery.
If you are planning to use a lead-acid battery then note that the life cycle and the depth of discharge are correlated. Generally, deeper individual cycles also mean that the battery will provide fewer cycles overall.
In this case, I highly recommended looking for a deep cycle battery with a depth of discharge that can optimize its life cycle when strictly followed.
Voltage – This specific factor refers to the potential electrical difference. In typical cases, deep cycle and starter batteries are designed to have 12-volt DC (direct current). In some cases, RV owners decide to put together or combine 6-volt series as a means of building 12-volt batteries that they can use for their RV.
They combine such batteries by wiring them in a series. While 12-volt batteries can serve you well in the majority of cases, take note that you also have to consider the system your RV specifically uses.
Another thing to remember is that solar power kits, as well as other chargers, are capable of working with 24-volt batteries. You need a power inverter, in such case, as a means of converting DC to AC current so it can perfectly fit your battery.
The manner of charging – Another thing to consider is the way you will charge the battery. Find out whether you will be using a generator, solar power, or shore power when charging the battery you plan to use.
Of course, you are allowed to combine the three. However, in case you do not have one yet, a smart charger or charge controller is necessary. With this device, a charging profile will be used depending on the battery type you own. Such will make it possible for you to supply the correct charge at the perfect time.
The controller is also a big help in adjusting the voltage and current automatically, thereby offering protection to your battery. Such is possible regardless of whether the power is delivered from solar panels, generator, or outlet.
Power at low and high temperatures – It is also advisable to check the ability of the battery to provide power at low and high temperatures. In terms of low temperature, you will need a battery that can supply power in that instance in case you will be using it during the winter.
With the ability of the RV battery to operate at low temperature, you have an assurance that it can supply power even if you are in a 0-degree environment. Check your chosen battery to figure out if it can indeed survive even the lowest temperature in certain environments.
You also need to find out whether the battery is compatible for use in high-temperature areas. This capability is of equal importance to the one that is ideal for low temperatures. Such is even more important, especially if you plan to stay in a humid and hot area. Choose a battery that can sustain a temperature of at least 35 degrees.
Ability to withstand vibrations – Another vital consideration is the overall build quality of your chosen RV battery. Note that you need a solid and sturdy build quality as this makes the battery capable of withstanding shocks and vibrations that it might encounter.
It should be shock-resistant and should be able to handle vibrations; otherwise, you might end up spending more on repairs because of the damage that the mentioned scenarios can do to the battery.
Other Important Factors to Consider
What is an RV Battery?
An RV battery contributes a lot in ensuring that your onboard appliances will continue to function as you desire. Note that all the things stored in your RV fully depend on a 12-volt battery system as a means to function. With the batteries in your RV, you can’t expect your onboard devices and appliances to work.
In most RVs, there is what we call as the best RV house battery, which can be defined as a deep cycle battery mainly designed to store huge amounts of power. Such ability allows the battery to work for a long period of time.
To make things a bit clearer, take note that your RV battery serves as an effective storage device for electric power. In other words, it does not produce power. What it does is simply store the power in such a way that it turns into a chemical form.
How does it Work?
If you are still unsure about how RV batteries function then do not fret as there are also a lot of RV owners who are still unfamiliar about how these devices work. Fortunately, this article can now shed light on some of the most complicated issues behind the way the batteries function.
As a whole, RV batteries and electrical systems are quite complex. To make it easier for you to understand them as well as topics related to RV battery charging, then I highly advise learning more about voltages. It should be noted that RV batteries operate at 12-volt direct current (DC) deep cycle electrical energy.
In most cases, such energy is enough if your goal is to have some source of power for small RV appliances and systems. However, you can’t expect it to run all your systems. The batteries, especially the deep-cycle ones, are actually manufactured to recharge and discharge repeatedly without causing damage to them.
One more thing that you have to understand in the way they work is that most of these batteries have amp-hour measurements. This means that a single amp drawn for just an hour. In other cases, the batteries can draw amps over a period of 20 hours.
The 12-volt batteries are mainly utilized as a means of charging specific systems all throughout your vehicle. In case you do not rely on the battery to obtain power then expect to be plugged to a shore power. This often has 120-volt alternating current (AC) power.
You can expect this to supply a lot of power to the systems in your recreational vehicle. Moreover, it is useful when it comes to charging the batteries in your RV. Each time the battery loses its power or discharges, you can’t expect it to recharge itself just like what happens in an automotive battery.
With that said, be responsible when it comes to keeping track of your battery levels. Such monitoring is helpful in ensuring that the charge does not fall too high nor too low. Once it is time for you to charge the battery, what you have to do is to just plug it into your vehicle.
Just look for an outlet, which runs at 120 volts AC, and plug the battery there. Note, however, that such outlet puts out AC power, instead of the 12-volt DC power often required by the battery. With that in mind, ensure that you also own a power converter.
Having this converter around can minimize the risk of dealing with unwanted electrical issues. Also, take note that using both the converter and shore power at the same time takes a long time to function, especially if your RV battery has a low charge or is already depleted. It can be quite annoying, especially if you need power right away.
Types of RV Batteries
The majority of recreational vehicles today depend on deep cycle batteries to work. Things like small water pumps, portable coffee machines, and large appliances, such as televisions, refrigerators, air conditioning units, and microwaves rely on this battery.
Note that deep cycle batteries supply a specific amount of current steadily over a long period. That is the main reason why many consider it as one of the most crucial parts of the electrical system of a recreational vehicle. With its help, all your onboard electronics and appliances will be able to run in case there is no supply of 110-volt power.
Your deep cycle batteries also provide you with a way to pump water to your freshwater tank or run your fridge and electric fan. By having it around, your electrical needs while you are inside your vehicle will constantly be met. Also, take note that a deep cycle battery for a recreational battery can discharge 50 to 70 percent of its full capacity.
Each time you recharge the batteries, you can expect them to redeposit energy into the bank, allowing the cycle and process to begin. This battery also features thick plates with less surface area.
However, you have to know that it comes in various types and you have to gain full awareness about what each one can do so you can better decide which one to choose.
Flooded lead-acid – Also called wet cells, this type of deep cycle battery is based upon the lead-acid chemistry that was discovered by Gaston Plante in the year 1959. It is the most famous deep cycle battery used for RV’s today. It used the word flooded since it comes with electrolyte fluid, allowing the plates to be fully submerged.
It is mainly composed of lead-oxide and lead plates and has an electrolyte that surrounds them. If you take electricity from the battery, which is referred to as discharging, you will notice that the plates start to change into lead sulfate. This also results in the dilution of the electrolyte.
Charging it, which involves putting electricity back to the battery, can take the sulfate coating out of the plates, moving them back to the electrolyte. This results to it being more concentrated. This eventually causes the plates to go back to lead-oxide and lead. During charging, oxygen and hydrogen will also be released.
This type of RV battery is actually popular for its numerous benefits, including the following:
Works effectively in handling overcharging – In comparison to other types of deep cycle batteries, the flooded lead-acid can manage the process of overcharging more effectively. It is mainly because of the hydrogen venting process as well as the fact that it is not sealed.
Long life – Another benefit of the flooded lead-acid battery is that it has a long life. You can expect it to be able to serve its purpose for quite a long time. While this battery requires constant maintenance through watering, maintaining the cleanliness of the terminals, and equalizing charges, an hour annually will do just fine in keeping its good condition.
AGM (Absorbed Glass Mat) – This is another type of deep cycle battery that is ideal for RV applications. In fact, it works well for the majority of applications. It is compatible not only with RVs but also with trucks, boats, and trolling motors. In comparison to the flooded battery, AGM is often tougher and stronger.
It also requires less maintenance. It is actually a form of a lead-acid battery wherein a fiberglass mat absorbs the electrolytes. Among the distinguishing features of AGM are its plates that appear as flat-like flooded lead-acid batteries. You may also notice them winding into a tight spiral.
It has a lower internal resistance than flooded cells and is capable of handling high temperatures. AGM is also known to self-discharge slower than other batteries. It is different from flooded batteries considering the fact that glass mats are used in holding the electrolyte instead of freely allowing the plates to flood.
It also makes use of thin glass fibers. The manufacturers weave these fibers into the mat as a means of increasing their surface area, making it possible for them to hold enough electrolytes for a long time. To know whether AGM batteries are good for your RV, here are some of the benefits you can gain from them:
Maintenance-free – What is good about AGM deep cycle batteries is that they do not require a lot of maintenance. The flooded lead-acid battery actually needs regular maintenance as well as a topping charge semi-annually to minimize the risk of accumulating sulfation.
AGM, on the other hand, is not that vulnerable to sulfation. With that, you have an assurance that you can easily store it for a longer period without worrying about potential damage. You can even expect it to maintain its good condition for up to a year, provided proper care is given to them.
Even after such a long period of sitting idle, you can recharge it and expect it to perform its job again without any damage. It makes a great choice, especially if you are looking for a battery, which does not need too much maintenance.
Does not spill – This specifically means that the AGM battery does not cause its electrolyte to spill out even if it is turned upside down.
Does not emit hydrogen or gas – Another impressive advantage of AGM batteries is that they do not emit hydrogen or gas during charging. With that, you no longer need to worry too much about ventilation each time you charge them. This benefit can also ensure that you will stay safe when using the battery within your motorhome.
Stable and sturdy – AGM batteries are stable and sturdy enough. In fact, you can expect them to stay in good condition even during extremely low temperatures. They do not freeze in such a case. The batteries are also great options because their sandwich construction makes them even more vibration-resistant.
Deep cycle gel – You can also opt to install the deep cycle gel battery into your recreational vehicle. It has some of the advantages offered by the flooded lead-acid battery, such as being easy to transform. The only difference is that it comes with gelled electrolyte, which is highly viscous.
Recombining the gases that you have generated while charging also takes place at a slower rate. In other words, charging the battery needs to be done slower when compared to AGM and flooded lead-acid. Also, charging it too high might cause the formation of gas pockets on the plates.
This might decrease its capacity as it forces the electrolyte away from the plates. Another thing to take note of about deep cycle gel batteries is that they come with narrow charging profiles. This is the main reason why they get easily damaged through inappropriate charging.
With that in mind, take note that while it is one type of RV batteries, many still prefer the others to ensure that they will not end up dealing with certain issues when using them. It would also be best to avoid using it in case you have no experience working with battery chargers and batteries.
Lithium-ion – You can also go for lithium-ion if you are looking for the perfect type of deep cycle battery for your recreational vehicle. Some even say that it is the right RV battery out of its different types. One reason why lithium-ion is a better option than AGM and flooded lead-acid is that it is lightweight.
It is also capable of offering users with a high charging efficiency as well as life cycles from 3000 to 5000.
Benefits of RV Batteries
Here are just some benefits that you can get from choosing lithium-ion deep cycle RV batteries:
Guaranteed to be safe – One thing that sets lithium-ion batteries apart from the rest is the inclusion of a built-in safety measure. Once the battery is already close to overheating temperatures, it shuts down automatically, thereby preventing explosion or fire.
Goes further – Another benefit of the lithium-ion battery is that it is capable of going further compared to lead-acid, which only lets you utilize approximately 50 percent of its rated capacity. With that, you have an assurance that lithium-ion works well if you want to extend dry camping.
It also features highly sustainable voltage levels, making it possible for it to provide up to 99 percent usable capacity. With that, you will have extra time on the road while you are away from your actual home.
Weighs less – Another great advantage of this type of battery is that it is lightweight. Note that your recreational vehicle is already heavy and big, so you may want to look for a battery, which is not that heavy. This is something that the lithium-ion battery can guarantee.
It weighs less than the traditional lead-acid battery. With a lower weight, you can expect it to be a major help if you want to boost your RV’s capacity as far as speed is concerned.
Eco-friendly – You will also love the fact that lithium-ion batteries are environmentally friendly. They are totally safe for the environment, making them ideal green options. They are designed to supply power to your travels through clean energy while minimizing CO2 emissions.
Disposing of these batteries is safe and friendly to the environment, too. Furthermore, these are often constructed out of recycled materials and are recyclable.
Frequently Asked Questions (FAQs)
What are the different types of RV batteries? Which one do I need?
The battery used in powering an RV’s coach often requires to have a deep-cycle design. It is because this design makes it capable of withstanding deep and frequent discharging as well as its typically received recharging. You can’t expect engine-starting batteries to last long in case you use it as an alternative to deep-cycle batteries.
In this case, one of your most reliable choices for the RV battery is the lightweight lithium-ion battery. This specific type of battery starts to gain recognition in the market because aside from being lightweight, it is also maintenance free. It also offers more power storage based on its weight and size.
However, some RV owners find it too expensive. For those who are interested to go for deep-cycle RV batteries, the most commonly used types and designs under this category are divided into three – the conventional flooded cell battery, the gel battery, and the absorbed glass mat (AGM) battery.
The flooded cell battery is usually installed as an original equipment. Offered at a low price, it is possible for this battery to deliver a good capacity for power. It should be noted that it falls under the category of using wet cells that require the periodic or regular filling of water.
Ensure that you are using distilled water for this purpose, though, to prevent the buildup of minerals. Also, take note that since wet cell batteries utilize more water during a hot weather as well as during frequent recharging and discharging, it is crucial to service them in a more frequent manner during that temperature.
Being a wet cell battery also means that you need to do terminal cleaning regularly. Another type of battery that you can use in your recreational vehicle is the gel battery. This type of battery comes with a thick-jelled electrolyte, not liquid, to prevent it from spilling just in case it is tipped briefly on the side.
It does not also need frequent water refills. While it costs higher than wet cell batteries, many still prefer the gel battery because it tends to last longer. The AGM RV battery is also another type that you can use for your RV. Just like the gel type, it does not require the use of water.
It is mainly because it has a fiberglass matting wrapped around its lead plates designed to soak the electrolyte. You can mount it on its side. The AGM RV deep cycle batteries are the most expensive types of battery but expect them to be maintenance-free and long-lasting.
With the mentioned qualities of each battery, you might be able to choose the right one for your needs.
What is an RV deep cycle battery?
An RV deep cycle battery is where the majority of the onboard appliances and electronics in an RV, like coffee machines, water pumps, TV, air conditioner, microwave, and refrigerator rely on. It is designed in such a way that it can supply a steady current for a prolonged period of time.
This type of battery is different from starting battery, which is mainly designed to supply high energy burst for just a short period as a means of cranking the engine’s starter. The RV deep cycle battery is actually designed in such a way that it can discharge around 50 to 70 percent of its overall capacity based on its construction and manufacturer.
Each time you recharge the battery, the energy will be re-deposited into its bank, stimulating the start of the cycle or process again. In comparison to starting batteries, the deep cycle comes with thicker plates. It is also built to be solid, instead of a sponge. The thicker plates used in the deep cycle also come with less surface area.
This subsequently means that it requires less instant power than a starting battery. It is also designed in a way that it can discharge up to 20% of its max charge on a repetitive manner. It is mainly because of its thick lead plates that are sturdier compared to its sponge counterpart.
What is the best charger for the RV battery?
Many recreational vehicles are equipped with battery charging systems. However, some of them are also poor performers. Others, on the other hand, are primarily designed to top up the battery when you plug it at RV parks. In some cases, the built-in chargers in old RVs might also damage the batteries through overcharging.
With that in mind, it is really a must to locate the ideal charger for your RV battery. One of your best choices is the converter charger. The main objective of this charger is to convert 120-volt of shore power into 12-volt DC power. This is necessary in ensuring that your RV battery no longer has to supply DC in case you are plugged in.
Another function of this battery charging option is to charge your battery during those instances when it has an excess capacity. Rated in amps, it is capable of supplying the circuit boards of your RV’s lighting and appliances with enough power. It is also enough to provide charging.
In most cases, the converter charger used for RV batteries is combined with the primary power distribution panel. You may also choose the inverter charger. It is usually used in Modern Class A motorhomes, as well as a few other trailers and vehicles. It is capable of delivering similar functions as the converter charger.
The only difference is that it has the ability to deliver 120vac from a 12-volt battery in case there is no available shore power.
How to charge an RV battery with solar panels?
You have an option of charging your RV battery with the help of solar panels. What is good about the solar panel is that it is capable of producing up to a hundred percent full watt output when you place it in direct sunlight.
Charging your RV battery with the right solar panel, however, requires you to first consider some factors and answers to some questions. One thing to determine is the length of time it would take for your solar panel to charge the 12-volt battery completely. You also need to determine the perfect wattage for the solar charger.
Furthermore, you have to make use of a controller just in case you picked a fully functioning solar panel. Some models actually come with illuminated LEDs that provide information about whether or not the solar panel charges your RV battery. Some models also come with built-in controllers designed to block the charge in case of full battery.
How to charge an RV battery with a generator?
If you are planning to use a generator to charge the RV battery then take note that it is also advisable to follow some steps. The first thing you have to do is to charge the generator fully or plug it into your AC outlet. Turn off your recreational vehicle and engage the emergency brake as a means of preventing accidents.
Determine the exact location of the battery then inspect it to see if there are cracks, corrosion, and bulging. The next step is reconnecting the RV battery. You can do that by connective the positive (red) cable then the negative (black) one. Use a wrench to fasten it securely.
Maximize the charging process by unplugging all the onboard electronics and appliances in your RV. The lights should be turned off, too. If it’s possible to plug your generator into an AC outlet, which runs at 120 volts, plug it in. Also, remember that if you use a portable generator, which uses a 12-volt C output, the charging process might take slow.
The time it takes to charge the RV battery is also dependent on the weather. It is greatly possible for you to be unable to obtain the full capacity in case the temperature is just below 40 degrees. The next thing to do is plugging the plug of your recreational vehicle to the generator.
Note that it might take a max of two hours to charge the battery fully in case it is not depleted. However, if the battery has already dropped lower than 20 percent then it might take longer to charge it.
Once you have successfully charged the battery using your generator, make sure to use your electronics and appliances wisely until you reach the campground. Plug your generator as soon as possible so you can use it in the future.
How to charge RV battery while driving?
In case you need to charge your RV battery when you are driving, rest assured that you can do that using simple steps. The only things that you need are Anderson plugs, high-quality and high-amp cables, and VCR or the voltage controlled relay. Begin the process of recharging by preparing the VCR.
This VCR will disconnect automatically and parallel the auxiliary. It also works in starting the batteries. This will close the relay and cause your truck and its batteries to be parallel based on the preset level. When you turn on the vehicle, it opens the relay. You can also expect the two batteries to be disconnected in case the vehicle is off.
It will then bring the voltage to a preset level. The next step is using the high-amp cables in combining the batteries as means of reducing the drop in voltage. You should use the Anderson plugs as these are designed to provide an excellent connection while minimizing the loss of voltage. The plugs can also carry a high amp.
Ensure that the cables are easy to detach at the tow bar. It is also possible to get rid of any fire hazard using the circuit protection that usually comes in a 50-amp auto reset circuit breaker form. Several rubber boots can also be slipped on into the breakers as a means of insulating them, thereby preventing them from shorting.
How to install an RV battery disconnect switch?
The battery disconnect switch of your recreational vehicle looks similar to a plunger switch. You can often find it either outside close to the battery compartment. In some cases, it might also be visible on the inner control panel. This disconnect switch is essential in cutting the flow that comes to the negative cable.
With that, there is an assurance that nothing will be capable of drawing power from your RV battery. In case the switch is not present in your vehicle, then rest assured that you can install an aftermarket switch or remove the connection of the negative cable to obtain a similar effect.
In terms of installation, rest assured that the process is easy and quick. In most cases, the installation involves running the negative cable of the battery – the one, which comes from the vehicle to one of the switch’s side. You also need to run a shorter cable coming from the switch then to the RV battery.
Turning the switch will disconnect the two cables, allowing you to have a disconnected battery, which is possible without the need to use a wrench each time.
How long does an RV battery last?
An RV battery has a different lifespan, and this is dependent on the way you use it. In most cases, though, it can last for up to 5 years provided you use it correctly. You need to give the battery proper maintenance. Note that the battery in your RV works similarly to a marine battery, so you need to use it completely.
When it comes to replacing the battery, note that it is essential to take the negative cable out first. In terms of reconnecting, rewiring the positive cable should come first. It is also advisable to clean the connections prior to securing them on their places.
Another thing you have to do is to monitor the battery’s electrolyte level. It is mainly because your battery might fail prematurely in case it has a low level of electrolyte. Avoid overfilling it, too.
The best RV battery can help ensure that you will enjoy an uninterrupted journey. With a fully functioning and high-quality RV battery, you will never end up facing the consequence of your vehicle dying on you in the middle of the road. It ensures an uninterrupted and enjoyable trip.
