    Deep Cycle Battery Defined

    5-best-RV-deep-cycle-batteries

    A deep cycle battery is one with thicker plates while also being capable of surviving numerous discharge cycles. It is a good choice, especially if what you are searching for is a type of battery designed for renewable and solar energy or one, which perfectly suits camping.

    It is mainly because of its ability to use less instant energy while still delivering a great energy for the long term. One advantage of deep cycle battery is that it is highly efficient as far as working as an energy storage unit is concerned. It works whenever there is a chemical reaction, which produces a voltage resulting in electricity.

    Also, take note that a deep cycle battery is designed in such a way that it cycles (discharges and recharges) several times. With that said, it can provide a steady rate of power for a prolonged period, which makes it different from standard car batteries that only aim to provide a burst of energy within just a short time.

    One of the most common types of deep cycle battery is the AGM (short for absorbent glass mat). It is actually a form of lead-acid deep cycle battery, which comes with a fiberglass mat designed to absorb electrolyte. It has flat plates and comes with a lower internal resistance when compared to traditional cells.

    AGM deep cycle batteries are also capable of handling high temperatures while also doing the self-discharge process at a slower rate than other kinds. Overall, many choose AGM because of its many benefits, including the ease and safety involved when transporting it and the fact that it is completely sealed.

    It is also a popular type of deep cycle battery as you can safely mount it not only in your RV but also in a caravan, car, boat, or motorhome. You can also go for the deep-cycle flooded battery you plan to install it in an easy-to-access site.

    Regardless of the type of RV deep cycle battery you choose, take note that the best one works well for you, especially if what you are looking for is a battery for cyclic applications. Some examples of these are running lights, high-performance car stereos, radios, fish finders, and accessories.

    The fact that it has thicker-sized lead plates than other batteries makes it possible to provide current for a long period of time. To give you an idea about the best products for deep cycle batteries today, here are five of those that are suitable for recreational vehicles.

    RV Deep Cycle Battery Buyer's Guide

    best-RV-deep-cycle-battery

    Selecting the best RV deep cycle battery out of the many products in the market today should not be that hard. Just make sure that you look for one, which makes use of a technology, which is suitable for the application and purpose you intend it to perform.

    As mentioned a while ago, the flooded deep cycle battery is ideal if it’s for an easy-to-access site. It is because this type has a widespread availability while also being available at a low price. However, if you plan to install it in a remote location, then go for gel or AGM batteries even if they cost a bit higher.

    It is because being in such a remote location can’t give you a guarantee that there will be a regular maintenance for it. Since the gel-type or the AGM deep cycle batteries are maintenance-free, they perfectly suit that situation. Choosing the best deep cycle battery reviews for your recreational vehicle should also be done while considering these factors:

    Cranking Ampere

    As it refers to the power supplied by the deep cycle battery when it operates at locations and environments with around 35-degree F temperatures, the cranking ampere is an extremely important factor to consider in your buying decision.

    It gives you an idea about its possible performance when used in temperatures that are over the water’s freezing point. If you go for a battery with a high cranking ampere rating, then you are also assured of its impressive starting performance.

    Cold Cranking Ampere

    This factor specifically refers to the power supplied by a battery in case its starting motor derives power from it in locations with less than 0-degree F. It is an essential factor to consider, especially if you plan to use your vehicle during the winter season.

    Remember that the performance of your battery might get degraded if you use it at low temperature. With that in mind, you really need a high cold cranking ampere rating to give you an assurance that it will work efficiently in supplying enough power for the starting of your engine even if it is exposed to cold temperatures.

    Weight and Size

    The weight and size of the battery also contribute a lot to its overall performance. You can’t expect the battery to give you satisfaction no matter how cheap or high-quality it is if it is too heavy and bulky that you already have a difficult time moving it conveniently.

    You can find brands that offer heavy-duty batteries. While they are great options, make sure that you spend time assessing how heavy they are. Note that there are heavy-duty types that weigh up to 2,000 pounds while being in a 12-volt pack. That’s a lot of weight to handle.

    However, you should also avoid ending up with having to buy around 50-60 small batteries as such might cause problems in wiring them up and maintaining them. What you have to do then is to remember the basic rule of maintaining the total number of batteries to use at around 8-12 only.

    In the event that you think a higher capacity is required, then consider investing in batteries with bigger sizes but not the very small ones. Make sure that they are not too bulky and heavy, though. The goal is finding the right balance between weight and size.

    Technology Used

    Choosing the best deep cycle battery for RV is also possible by spending time assessing the technology used in each one. Basically, all batteries designed for recreational vehicles make use of lead-acid technology although each one comes in various packages.

    One of the most basic packages is the flooded cell wherein the battery is packed in an acid solution or liquid water. You can also go for the latest models designed with a maintenance-free technology. Such models attempt to minimize the risk of losing electrolytes through the process of sealing the cells.

    The problem with this latest model is that it is not that effective when used on frequent and heavy charging. You may also opt for the gel type, which utilizes a thick paste electrolyte while having a full seal. Find out what specific technology is used in a particular battery to ensure that you are getting the right one.

    Cycle Life

    The cycle life of a battery can actually be measured based on the number of charge or discharge cycles it can provide based on a given percentage of its rated capacity. Various manufacturers may create their deep cycle batteries with a similar capacity rating.

    The problem is that they differ in design, process and materials used, quality control, and experience – all of which can have a heavy influence on the performance of their cycle life. That said, this factor really plays a vital role in your decision.

    Capacity

    Spend time reviewing the battery’s capacity so you will know whether it receives a proper rating based on its intended application. Note that this factor is important as a battery with inadequate capacity has the tendency of over-discharging regularly, resulting in a shorter life.

    Also, take note that you should avoid getting an oversized battery. It is mainly because of its high price tag, which might not correspond with its actual value. What you have to look for is to identify the purpose or application you wish the battery to perform and figure out the ideal capacity for it.

    Brand

    Research about the most reputable brands of deep cycle batteries today. Make sure that you really figure out which among these brands can give you the highest level of satisfaction.

    You can do that by spending time researching the history of the brand, especially in manufacturing and engineering high-quality deep cycle batteries specifically designed for renewable energy and recreational vehicle applications.

    Price

    Compare the prices and the features of different batteries, too. While it is tempting to buy one because of its low price, you have to make sure that it is not offered at such a low price because of its subpar quality and low cycle life performance.

    Note that while you can save if you go for the cheapest battery available in the market, you will be spending more in the long run because of the need to replace it too frequently. That said, figure out which battery is offered at the most reasonable price while also giving you real value for the amount you spend.

    Shock and Vibration Resistance

    Look for a deep cycle battery, which is really effective in resisting shocks and vibrations. It should be able to withstand such issues without any drop or failure in performance even if you use your vehicle for off-roading.

    Conclusion

    By considering all the factors mentioned in the short buying guide, you can figure out which among the best RV deep cycle batteries introduced to you is best for your purpose. Do not forget to consider the reserve capacity and ampere-hour rating of the battery, too, as both have a huge impact on its overall performance.
