The Ultimate Guide What To Look For Best RVÂ Battery
Since you made it this far, perhaps you have already decided what to pick, but you have missed a big part my friend. The battery review will not be complete without mentioning the ultimate buying guide.
However, we have already discussed some best RV Battery on the market and hope that aware of it in detail. Here, in this part of the article, we try to cover up the entire buying guide that will help you to decide what to choose. So let’s start:
Starting vs. Deep Cycle battery vs. Dual Purpose
As we mentioned earlier, the mechanism of extended Cycle is a bit different from Dual Purpose or Starting.
Starting batteries are known as cranking batteries, designed to release a huge amount of energy, mainly for a short period. These batteries are suitable for starting engines like inboard/ outboard marine engines or automotive engine.
On the other hand, long-cycle batteries are engineered to discharge a little bit of energy for a long period. Another big difference is by visualizing a marathon runner and a sprinter. Thus, a starting battery is more likely the sprinter which provides lots of power. Meanwhile, the long cycle battery is also a marathon runner who offers less speed but greater endurance.
Dual purpose batteries can both deep cycling and starting engines. But they are not ideal for the performance of extended-cycle battery
Types of RV Deep Cycle Batteries
Deep cycle RV batteries are engineered of four common types. They are:
- Sealed Absorbed Glass Mat
- Flooded Lead Acid Deep Cycle Batteries
- Gel Sealed
- Lithium-ion Deep Cycle Batteries
Each battery has its pros and cons. So what is going to be the right choice for you, it mainly depends on your needs and desire. So let’s have an insight into deep cycle battery types comparison.
- Sealed Absorbed Glass Mat
Absorbent Glass Mat (AGM) technology comes to lama light in the early 1980s as a reliable battery for UPS, military aircraft, and vehicles to reduce weight and improve efficiency. However, AGM deep cycle batteries are ideal for Harley Davidsons, boats, trucks, trolling motors, and recreational vehicles.
They are always better, tougher, less maintenance and stronger than flooded batteries. At the meantime, The AGM battery is a kind of lead-acid battery where the electrolyte occupies with a fiberglass mat. There is two types of AGM.
- Flat plat AGM
- Spiral AGM
- Flooded Lead Acid Deep Cycle Batteries
Flooded lead-acid batteries or wet cells, were discovered by Gaston Plant© in 1859. The term “flooded” is because it contains an amount of electrolyte fluid where the plates are submerged.
However, it consists of lead-oxide plates surrounded by a mixture of water (H2O) and sulfuric acid (H2SO4) which creates an electrolyte.
Furthermore, they need off-season charging and regular maintenance, have to be installed in an upright position and are sensitive to a high range of vibration. But they have a long life cycle.
- Gel Sealed Deep Cycle Batteries
Gel batteries are the older version of AGM and faded away its market when the latest version AGM comes. Thus, it has many benefits like ease of transportation, generated gases. On the other hand, it has to charge slower than AGM batteries or flooded lead acid.
In a nutshell, they are the very narrow profile for charging. As a result, it can damage easily if it charged inappropriately.
- Lithium-ion Deep Cycle Batteries
The promote Lithium-ion Batteries exceeds the performance of AGM batteries and Flooded Lead Acid. More than anything, they are pretty lightweight and provide charging efficiency between 3000-5000.
The thing we liked most is it’s 2.5 times more efficient in abnormal temperature. It is capable enough to absorb low temperature as well as function safely up to 149*F. However, versatile mounting granted the battery to be installed in any position and direction. The vital fact is that they are very costly.
How deep cycle batteries work
Let me first clear difference between deep cycle and marine battery. The main difference between a regular starter battery and a deep cycle battery is the amount of energy it releases and the way it has been discharged.
AutoÂ howstuffÂ tells us a lot of difference about A normal lead acid battery and a deep cycle battery
Deep cycle batteries are engineered to discharge a decent percentage of capacity. The process is called deep discharge. On the other hand, Starter batteries are designed to discharge a little amount of power at any time.
As the starter battery has to charge deeply, it will affect the total lifespan as well as the ability to charge. Most deep cycle batteries are capable of discharging up to seventy percent without suffering any type of damage. The amount of discharge may vary from manufacturer to manufacturer.
What is The Best RV deep cycle battery? 6 volts or 12 volts?
What will be better for RV, 6 volts or 12 volts? Well, let’s figure out what is the big deal about volts. Generally speaking, a 6-volt battery is a golf cart battery. However, they are the finest versatile batteries available for a cabin, small home, or outdoor.
At the same time, they are ideal for the RV and more cost-effective 12-volt batteries for the long run. Meanwhile, if you tend to go with your RV from park to park and 12-volt deep cycle batteries will be just fine.
But if you are planning to go for boondocking or dry camping where you need the stored energy, you should pick four or six-volt batteries.
Factors to Look For When Choosing a Deep Cycle Battery
Before you pick the RV deep cycle battery for you, you should consider some facts. Which is the top battery? Well, it depends on the purpose you aim it to perform. So have an insight into what factors should be considered in buying an awesome deep cycle battery.
- Cranking Ampere: The cranking ampere is an important fact to consider before your purchasing decision, as it used to the power supplier when it operates at environment and location with around 35-degree F temperatures. Thus, it gives an idea about the possible performance at different temperatures. So for better performance, go for the battery which has a high cranking ampere rating.
- Technology Used: Most of the deep cycle battery designed mainly for recreational vehicles with the use of lead-acid technology. However, in the flooded cell batteries are packed in liquid water or an acid solution. We highly recommend picking the battery which has maintenance-free technology.
This technology reduces the risk of releasing electrolytes. But the main problem comes when you charged it heavily or frequently. So first of all, figure out what technology is behind that particular battery to ensure that you are picking the right one.
- Cold Cranking Ampere:Â Cold Cranking Ampere refers to the energy supplied by the battery. At the same time, it starts motor obtains power from the battery in a location within less than 0-degree F. However; Cold Cranking Ampere is an important factor to consider. On the other hand, if you want to use your RV in the winter season.
Keep in mind that, battery with Cold Cranking Ampere might be degraded if you apply at low temperatures. Also, remember that; always choose the battery which has the high cold cranking ampere rating. So it can expose to extreme cold temperature.
- Shock and Vibration Resistance: Ensure that what battery you are picking has vibration and shock resistance. However, it is a must-have feature of the battery. Thus, the battery should capable of withstanding these issues without any failure or drop in performance even in off-roading.
- Weight and Size: The next thing you should consider is weight and size. Thus, they play a significant role in overall performance. Why are they important? Well, if pick something bulky or heavy, you can’t move it conveniently.
There are lots of manufacturers who produce heavy-duty batteries. Though they are a good option, ensure that they are good enough. Point to be noted is that the weight of these heavy-duty types is up to 2000 pounds with the 12-volt pack. Meanwhile, having near 50-60 small batteries will not be a good decision. At the same time, consider investing in a bigger battery size striving to find a good balance of size and weight.
- Capacity: The next noticeable thing you should have to look is the battery’s capacity. It’s an essential factor because by this you can assume the proper rating and its working ability. In the meantime, inadequate capacity requires over-discharging regularly. As a result, it will shorten the battery life.
Also, remember that don’t choose an oversized battery for your RV. First of all, figure out the need and the capacity it can fulfill.
- Brand: First, research what brands are managed to gain customer trust by their great performance. Also, find out what are the reputed brands in this industry. Then, figure out which brands are giving the utmost level of satisfaction. However, some of the reputed brands in this industry are:
- Mighty Max
- XS Power
- Cycle Life: what about deep cycle battery lifespan?
The cycle life of an RV battery can be measured derived from discharge cycles or some charges the battery can provide on a specific percentage. Different manufacture tends to create these deep cycle batteries in the same capacity rating.
However, the problem arises when they differ in material, design, quality control, process and experience which have a great influence on its performance. Moreover, it plays a vital role in your buying decision.
- Price: More than anything, the price is the most vital factor. Thus, compare the feature and prices of a different brand, too. Most of the people think that price is everything to get the excellentÂ RV deep cycle battery.
But you can find plenty of battery which offersÂ an amazingÂ feature at an affordable price. Point to be noted that if you aim to go for the cheapest battery, you have to compromise with the quality. So try to find out that brand who never compromise about quality.
Four Things to Know About Your Deep Cycle RV Battery
Everything in the RV relies on the volt system to perform. Thus, without the RV batteries, your recreation vehicle will not work properly. In a nutshell, RV batteries are mainly long cycle batteries that are designed to keep large amounts of power to work after over a longer period.
Check the Battery Charge
Never use the battery when it consists of less than 50% of charge. So carefully recharge them as soon as possible, and never allow them to work in lower than 20% charge, it will cause damage. However, to avoid this situation follow the manual.
If you maintain it properly, it will last for seven years or even more. Also, follow theÂ deep cycle battery charging instructions and deep cycle battery voltage chart.
The Main Battery
If your battery consists of 12 volts in your main battery, it will supply enough to RV as well as other appliances such as a pump, fridge, and lighting. Also, you can use 2 six volts batteries, but it looks a little weird. So it is an essential factor to look for.
We all know RV batteries need big investment, so you should have enough knowledge on how to store it for the last longer.
We recommend never storing when they are discharged, only storing them in the right condition. However, if you want to function it well on your next trip, charge it properly after properly.
Monitoring RV Coach Battery
Disconnect your battery for at least 24 hours earlier checking the voltage. Gravity and temperature play a significant role. However, if you are using a gel battery, you can’t measure the voltage as there is no way to insert the hydrometer. Keep in mind that the lower the voltage, your battery is also charged less.
For example, the wired 6V RV batteries in parallel would be:
- 100% charged at 12.80 voltages
- 75% charged at 12.55 voltages
- 50% charged at 12.20 voltages
- 25% charged at 11.75 voltages
- 0% charged at 10.50 voltages
Tips on Maintaining RV Battery
RV batteries are pricey as well as sensitive, and therefore, you should take good care of these batteries. However, here are some tips for maintaining these valuable things.
Don’t Overcharge or Overheat
Keep an eye on the batteries during charging whether the charger is automatic or not. Never allow your battery to become overheated or overcharged. If you feel hot in touch, then immediately disconnect your charger and allow it to cool down.
To optimize the production of an RV deep-cycle/ marine battery, we highly recommend discharge it before it comes to below 50%. Meanwhile, it is a vital factor in its life cycle. However, if your battery is working above 90° F, the service life will be drastically reduced.
Determine the State of Charge
A battery’s state of charge is just the opposite of the depth of discharge. For example, the battery with 30% depth of discharge means 70% state of charge. If you are using the flooded lead-acid battery, then the easiest way to determine the depth of discharge is to use a hydrometer. On the other hand, we suggest a digital voltmeter for maintenance-free batteries.

The Do’s and Don’ts of RV Deep Cycle Battery
Here are the Do’s and Don’ts you should follow to ensure your battery has a long life.
- Use safety goggles to keep you secure.
- Ensure that terminal clamps are placed away from corrosion.
- Place the electric storage cell is right place and shape using grease or spray.
- Try to understand the physical signal of electric storage cell problem like dim lights.
- Don’t forget to turn off the lights while you are leaving the RV.
- Never allow the electric storage cell run out so check them twice a year.
- Don’t waste the energy for waiting or idle time.

14 Best RV Deep Cycle Battery FAQs
Q: Do RV deep-cycle /marine batteries spread a memory?
A: No. The lead-acid battery does not expend a memory effect. However, it can cycle to different amounts of depth-of-discharge in their service life.
Q: What is the basic difference between a car battery and a deep cycle battery?
A: An engine battery or car battery is designed to offer a rapid burst of extreme energy to start the engine. Thus, they contain a high rate of Cold Cranking Amps (CCA). By contrast, a deep cycle battery is a “house” battery for the RV which will deliver the power of the daily needs. Furthermore, these type of batteries discharges 40% to 50% of its total power.
Q: How do I calculate the RV’s energy needs?
A: Make an audit of the devices or the applicants in the RV and how much Ampere it pulls to perform. Also, prepare a tally of how much it needs per day and how long it lasts.
Q: How are batteries Functioning?
A: Battery works in many systematic ways. You also read this article to learn how RV deep-cycle batteries work.
