What Is An RV Battery

An RV deep cycle battery is a sturdy and efficient battery that recreational vehicle owners rely on to power most of their onboard electronics and appliances, including water pumps, coffee machines, blenders, microwave ovens and TV, among others. This special battery is designed and made to supply your rig with a consistent current that can last for a longer period of time versus other traditional car batteries on the market do. Depending on its manufacturer and construction, the battery can discharge about 70% of its capacity.

How Does It Work

The deep cycle battery is designed and intended for repeated recharging and discharging. Every time you’re recharging it, its bank will collect the energy, starting the process or cycle again. When compared to starting batteries, the deep cycle type is made with thicker plates and with solid construction. There is less surface area in the thicker plates of these batteries, meaning less power needed versus a starting battery. And on a repetitive manner, the deep cycle batteries are designed in a way that they can discharge up to 20% of their max charge due to the thick plates stronger than sponge type plates.

Types Of RV Batteries

When choosing an RV battery, you must know the types available to determine what works best for you and what your rig needs. Generally, RV batteries are what you need because of their capacity to deal with frequent and deep discharging and recharging. It is better than the starting batteries that do not last as long if you’re going to use it for deep cycling purposes.

At the very least, you might want to consider the reliable lithium-ion battery, which is both efficient and lightweight. It can deliver continuous power supply and serve as good power storage, according to its size and weight. The three most common types of deep cycle batteries used by RV owners include AGM, gel battery and flooded cell batteries.

Usually, the flooded type cell battery is available at a lower price. It is also a good source of power for its capacity. However, it is under the wet cells group that requires regular or periodic distilled water filling in order to prevent mineral buildup. During a hot weather, the flooded type also needs more water and frequent cycling of discharging and recharging. So during hot temperatures, it requires more maintenance on your part. It also requires regular terminal cleaning.

On the other hand, there is the gel type of battery, which is characterized by its jelled electrolyte in order to prevent it from spilling just in case it was tipped. The gel type does not require frequent maintenance as the flooded type does. It can also last longer than the other type. The deep cycle battery type that you can mount on its side is also notable for its fiberglass matting around the lead plates. It has matting that works by soaking the electrolyte.

Lastly, there is the AGM battery type that is also the costliest of all, but in the end, it proves to be the longest lasting and maintenance-free. So if you’re looking for such benefits, you might want to opt for the AGM battery type for your rig.

There you have the types of deep cycle batteries to choose from and use as a backup power source for your recreational vehicle. Weigh your options well and pick one that suits your needs well.

Why Do You Need An RV Battery

The next question you might have is what the benefits of having a deep cycle battery for the recreational vehicle are. When planning to go off-grid, for instance, the deep cycle battery is a valuable companion to supply power to your RV electronics and appliances.

It is also a good battery that is designed and made for repeated discharging and recharging. This battery is also perfect energy storage for solar or wind energy applications. If you have it, you can also have peace of mind of having consistent power in places where you need a backup power source, such as camping grounds and parks without hookups.

Nevertheless, owning an RV deep cycle battery is important if you’re looking for backup power source, energy storage battery, starting battery or dual purpose battery, depending on the brand and manufacturer. And in all cases, having one also ensures of your loved ones’ comfort whenever they go dry camping or boondocking, as they can use their devices and the rig’s appliances and electronics without any hassles.

How We Picked

The next thing you might want to know is how to choose or what to look for a recreational vehicle battery. Considering and weighing your options well so that you can get the most of your investment. Check out the following for a guide on how to select the best type of deep cycle battery for your RV.

Voltage

Aside from amp-hour rating, you should also check on the voltage of the battery that can also mean the big difference between a good and a bad choice. Usually, starter and deep cycle ones have 12 volts of direct current power. On the other hand, some RV owners connect or combine 6V batteries to build a 12V system for their rig. However, the 12V battery is also the common choice. But in all cases, you should consider what battery system that your rig will always use.

Vibration and shock resistance

Finally, you have to consider whether or not the battery can handle constant shocks and vibrations in the rig. If it can, you can be sure that its performance will not be affected. Look for a sealed design that lets you mount it in any position without problems on leaks or spills. It must also have a solid or sturdy housing to ensure that it can handle shocks, impacts and vibrations, among other tough outdoor conditions. In all cases, you should also be looking for one with resistance to shocks to avoid spending on repairs.

Amp-hour rating or capacity

When choosing an RV battery, it is crucial that you check on its capacity to ensure that you can get your power needs out of it. The amp-hour (AH) rating is very important to consider because it can indicate the specific current amount that the battery is capable to supply over a period of time. For example, if the battery is rated at 100 AH, it only means that it can supply 100 amps per hour.

If you need more power, you should look for and buy a high capacity deep cell battery because it can also serve for a longer period of time aside from supplying a steady power source. But when shopping around, you might also want to check on the size and weight of the battery because it will also help you determine if it is the right size correct for the size of your vehicle.

To ensure you’re getting the right capacity, you might also want to look into the specific power requirements in your rig. For example, you should figure out the appliances you have onboard and how much time you need to run each of them. In addition, you have to determine the energy amount you need daily.

Also, you should pick one that can provide power without its total capacity going down to 50%. It is a great thing that you can also recharge the battery conveniently using the best RV solar panel, a generator, park’s hookup or battery charger. But then, if you’re planning to go off-grid for a couple of days, you should look for a deep cycle battery that can supply needed power consistently.

Discharge depth

What is its specific power discharged? It is one of the questions to answer when looking for the best RV house battery. If you’re choosing a lead-acid type, you should note that its discharge depth and life cycle are interconnected. Then, you also have to know that deeper individual cycles also indicate that it can provide only fewer cycles in general. Thus, you must look for a deep cycle type that has a discharge depth that is able to optimize its life cycle.

Power by temperature

What is the battery’s ability in supplying power at a specific temperature? For example, the battery must be able to work even at a low temperature so that you can be certain that it can keep on providing power even at freezing temperatures. And if you’re staying in a hot or humid area, you should also pick a battery that can sustain its performance even at temperatures of at least 35 degrees.

Charging method

It is another thing to consider when shopping around for good recreational vehicle battery. What is the manner of charging the deep cycle battery? What do you plan to use to recharge it – a shore power, a generator or solar power? You can use any of these or combine them when trying to charge the battery. But if you don’t have any of them, you can also consider using a charge controller or a smart charger, which can recharge the battery efficiently. You can use a charging profile based on the battery type you have, allowing you to charge your battery correctly.

You can also make use of a controller that has the ability of adjusting the current and voltage automatically, protecting your battery from damage. It does what it does well regardless you’re using power from a generator, outlet or solar panel.
