Buying Guides -How To Choose The Best Deep Cycle RV Battery?
Your choice of battery depends on your needs and purpose. The best deep cycle RV battery, which is the group 31R, weighs about 56 pounds per battery. This makes it light and easy to carry and install it inside or outside your camp. Deep Cycle is a good product for someone who hates heavy batteries that make their camping worse than expected.
In comparison with other types of deep cycle battery, RV Deep Cycle is different in size. This is because the manufacturer knows what people want from their batteries and how they will use them. The best choice for a deep cycle RV battery is a product that has a 48-inch height and is 16 inches wide. It can fit well inside your camper, because you have limited space to install your products.
3. Specific Gravity
Specific gravity shows how much energy you need to power up electronic appliances. In general, Figure electrolyte specific gravity values between 1.20 and 1.26 are recommended for marine batteries mainly used by RVs. If the manufacturer claims the specific gravity Figure value as 1.5, understand it as being very high, and you will not need to worry about your battery’s performance. Specific gravity figures that are lower than this value might damage the battery, which is very important when buying deep cycle batteries for RVs.
4. Cold Cranking Amps
I use my camper in all weather conditions and at any time I want, so having a good cold cranking amperes (CCA) rating for my RV Battery is essential. The best deep cycle RV batteries come with efficient CCA ratings of more than 550 amps. This allows me to get a better power supply for starting my engine compared to other types of deep cycle batteries.
5. Reserve Capacity
Reserve Capacity measures how long you can use your product without recharging it. If possible choose a model with a reserve capacity of one hour, because it will allow you to use your camper in emergencies.
6. Installation Location
You need to consider your needs and where you want to install your deep cycle RV battery before buying this type of product. If you want the best deep cycle RV batteries for sale, try choosing one that can fit on both inside and outside your camp. For example, if you live in an area with very low temperatures at night or during winter, choose an outside-installed battery so that it is not damaged easily by cold weather conditions. It is also important to check the terminal mounting position before buying a deep cycle RV Battery s . This way, you can be sure they are easy to connect with when necessary.
7. Batteries in Parallel or Series
Finally, when buying deep cycle RV batteries, you have to know if they are in series or parallel. This is because the type of connection affects your performance when using this product. When batteries are connected in parallel, their voltage adds up but ampere stays the same. On the other hand, if batteries are connected in series their voltage will add up but amperage will decrease. You can connect them in both ways for different purposes. For example, if you want to give a high amount of power supply for certain appliances you can connect them in series; however, most people usually prefer connecting them in parallel to increase total current without reducing voltage.
These types of batteries have a moderate lifespan, meaning that you have to maintain them properly to keep them working well. For example, it is important to fill all cells with distilled water when they are discharged or low. You also need to regularly check electrolyte levels and clean the battery’s case if necessary. This way, your deep cycle RV batteries are ready for full power without having issues.
This type of product has an average warranty period, which is about one year or more compared to other types of deep cycle batteries. If something goes wrong with the product during the warranty period, contact the manufacturer for repairs or replacements. However, some manufacturers do not offer warranties on RV Batteries. Hence it is better to read reviews before buying this product to have some idea about the experiences of other people with that company. This will help you decide whether or not you want to purchase their products.
You need to consider your budget and check out some of the best deep cycle RV batteries according to your needs.

Some of the most prominent companies include: CTEK America Inc ., Deka Motomaster, Odyssey Batteries, Interstate batteries, and more.
13. Other features to consider
There are other features which you might find useful as well when it comes to deep cycle RV batteries for sale. One of these is a state-of-charge LED indicator, which tells you if the battery needs any kind of maintenance or if it is already charged properly. You can also choose a product with a built-in desulphation mode if you want a model that keeps your battery in perfect condition. Another feature that some people may find useful is called “no freeze” technology, meaning that their operating temperature can go from -58 °F to +176°F. This way, you can use your battery in various conditions without having any issues.
14. Electricity Requirement
The electricity requirement of your appliances varies depending on the purpose of each one of them, which means that the amount of energy needed to run them is different as well. However, it is recommended that you check out your appliances and buy a suitable deep cycle battery for them. It also helps to use high-quality inverters which manage the power properly and do not damage your battery’s cells. If you want such a product, consider using Xantrex Technology Prowatt SW Series Pure Sine Wave Power Inverter, which manages electricity in an advanced way.
15. Discharge Rate
You should know more about the discharge rate rate of your appliance before purchasing batteries because it affects their lifespan significantly. For instance, if your appliances use 20% of the total energy every hour, then this means that they have a 5-hour discharge rate. This means that you should buy deep cycle batteries which are capable of discharging up to 80% in an hour. At the same time, you need to make sure that your battery is durable enough to handle this kind of capacity without issues.
Frequently Asked Questions
What Are Deep Cycle RV Batteries?
Deep cycle batteries are very different from your typical car battery. Deep one uses an increased number of plates, thicker plates, and can withstand being deeply discharged. Every time you draw energy from your battery, whether starting your RV engine or running your TV at night, you are doing so using amps. As you use power more quickly the amps drawn go up. A 100-watt light bulb draws 10 amps whereas a 1,000-watt microwave will pull 80 amps. Deep cycle batteries are rated in amps, with the most common ones being 35, 50, and 75. The higher the number of amps the battery is rated for over a period of time, the longer it will last. For example, if you have two identical 50 amp hour deep cycle batteries with one having an 8-hour rating and the other at 10 hours, after 10 hours they both would be completely drained. If you had four 6-hour rated batteries they would all still be ready to go at the end of those ten hours as well as 4 eight-hour batteries which would not be nearly as drained as those two 10’s. The reason for this has to do with how much power those batteries can deliver or absorb respectively before going dead or full. Discharge rate is measured in amps while charge rate is measured in amps, watts, or kilowatts.
How Do Deep Cycle RV Batteries Work?
If you plan on using any type of RV appliances, such as a microwave, radio, lights or even hooking up to shore power electric outlets, your starting battery MUST be in good shape. Your deep cycle batteries will not start your generator and even if they were able to it is very bad for them. A generator is best left running for hours at a time while an RV engine just runs a few minutes every couple of hours.
Some people think that you can run all your 12 volt appliances from one deep cycle battery which simply isn’t true. The problem with this thinking is that the difference between starting and deep cycle batteries is amperage flow rate. Deep cycle batteries have thicker plates with less surface area which means lower amps over a long period of time. Conversely, starting batteries have lighter plates with more surface area which allows them to put out higher amps for shorter periods of time. This is why your car battery can start your engine every day and last many years whereas if you used it like an RV deep cycle battery (used all the time) it would be dead in a couple of months.
If you do try to run too many appliances off one deep cycle battery eventually you will boil that battery dry and cause very expensive damage. The best way to use your 12 volt system is to wire each appliance into its own circuit using 3-prong plugs and turn on/off at the proper times, not just leave everything plugged in all the time like most people do.
What Kind Of An RV Deep Cycle Battery Should I Buy?
There are dozens of types and price ranges for deep cycle batteries. The most common type is the flooded or wet cell deep cycle battery that uses liquid electrolytes to produce electrical energy. You can put these in any orientation, they don’t care if they tip over. They are economical but need maintenance every few months on some models where you have to add distilled water. Some others require special plates while there are still others with fiberglass separators which will never allow the battery acid to leak out even if turned completely upside down or sideways. These usually cost more but last longer, 10 years or more is not unheard of with proper maintenance. Then there are AGM (absorbed glass mat) deep cycle batteries which use a fiberglass like a separator and an electrolyte in a jelly-like state, combined these allow even greater abuse and vibration resistance. The downside is they cost more and only work if the battery case has been specially designed for this type of battery, you can’t just drop any type onto an AGM battery or it will likely damage/destroy the cells.
The other option is to go with something even more stout, such as stainless steel plates/separators which are lead acid based but have no liquid at all so there is nothing to add or remove from time to time. These batteries last forever but cost a fortune compared to normal deep cycle wet cell types. If you plan on going off grid without having your
How Long Do Deep Cycle Batteries Last In An RV?
That really depends on how you use them. Most deep cycle batteries will last 1-3 years (or more) if used occasionally but can be damaged in as little as 6 months to a year if constantly drained down to 12.5 volts or less every day while camping without having an alternator to recharge them back up each night. It is important that your battery maintains at least 13.2 volts when charging with shore power/generator so it doesn’t boil the electrolyte out of the battery which permanently damages it. If you have AGM type deep cycle batteries they are even more susceptible to being killed by over-discharging so these should only be used for backups or second choice systems where you hook up just one appliance requiring 220 volts of power to keep it fully charged.
Should I Charge My RV Deep Cycle Battery After Every Use?
No. Most deep cycle batteries should only be charged after the battery has been drained below 80% charge (10.5-11.0 volts) or once every 30 days (whichever comes first). If you see your alternator light come on when running your generator then it is usually because you have an RV deep cycle house battery that hasn’t been properly maintained and needs to have the electrolytes checked/replaced or move it into a second battery location that isn’t constantly being drained down by appliances left turned on all the time, this way they are never fully discharged which will kill them much faster than if they were constantly being topped off daily with shore power.
How Many Times Can A RV Deep Cycle Battery Be Recharged?
A deep cycle battery can only be recharged a limited number of times before it needs to be replaced, which is usually around 500-750 cycles depending on the quality and type. Even if you never run out of power with your batteries you will experience shorter life spans with each recharge so avoid this at all cost by hooking up a generator or shore power daily when in an RV park with full hookups to keep the batteries constantly topped off.
How Do I Know If My RV Deep Cycle Battery Needs Replacing?
If you have ever boiled off electrolytes or had your house battery go dead just by leaving an appliance on for a few hours then it’s time to replace the batteries. If you don’t use your RV much and find yourself needing constant generator run time to keep everything charged up while boondocking then this is another sign that your batteries are not performing well enough anymore to handle these constant discharges/recharges. Most RV owners dump their old batteries when they get anywhere from 2-5 years old, but some people choose to rebuild them instead with new cells which can be expensive but restore the depth of discharge capacity back to full 100%. The other option is investing in military spec deep cycle batteries which are made to be discharged down as much as 80% of capacity without damage. These are pricey, but sometimes well worth the money depending on how many times you need to replace your RV deep cycle house battery each year.
RV Battery Life And How Long Do Deep Cycle Batteries Last? (Upgrading Your Stock Battery Bank)
We’ve talked about this before in another post but if you’re still using the stock group 24 deep cycle wet cell lead acid type house batteries that came with your travel trailer/motorhome then it’s definitely time to upgrade to more modern lithium ion or AGM types which will outlast the stock batteries by 3-4 times their life expectancy. There are plenty of advantages to having either of these types of batteries used in your RV, including not having to maintain them with distilled water or worry about electrolyte leaks, but one of the biggest advantages is simply how much more capacity they have compared to lead-acid wet cells which are very sensitive to being discharged below their 50% threshold.
Your first upgrade should be to at least two large lithium ion batteries wired together either in parallel or series/parallel depending on how many volts you need, both wiring configurations will safely double your battery bank capacity by combining them into one larger bank that can hold all the amps possible. This means you won’t need to bring as many generators out camping or have to run your big rig for hours just to keep your deep cycle house batteries charged up.
How Much Money Can I Save By Upgrading My RV Deep Cycle Batteries?
Depending on the size and number of batteries originally supplied to your coach and what type you choose to replace them with (lead-acid wet cell or lithium ion/AGM) you should easily get at least 2-3 times longer life out of each replacement set. For example, if you go from a group 24 lead acid battery bank which is 200 amp hours capacity down to two 100 AH 12 volt lithium ion batteries wired together in series/parallel like we talked about above, then that’s already twice the overall capacity without needing another generator run time while camping or having to worry about leaving an appliance on too long without running shore power again. Depending on how often you go camping and for how long each trip, it’s easy to see how this would quickly save you a lot of money compared to replacing your lead-acid batteries every few years.
Why Do I Need The Latest Technology Deep Cycle RV House Battery Bank?
Simply put, because they will last longer and take all the abuse you can throw at them without worrying about boiling off the electrolyte or catching on fire like wet cells tend to do if abused too much. Wet cell batteries are great as long as you’re okay with constantly checking their fluid levels and vent caps every week to make sure they stay topped off and that there is no visible white residue around those caps which means that acid has boiled over into them (a sure sign also that your battery is on its way out).
Lead-acid batteries also don’t like being discharged down below about 50% of their overall capacity before you have to recharge them again, and if they sit uncharged for long enough the internal plates start to warp and your battery bank becomes useless. What this means in reality is that if you plan on taking any camping trips more than several hours away from a charge (and who doesn’t these days) then you need an approach that can charge your RV house batteries quickly without boiling off electrolyte or needing hours of generator time while boondocking (camping without using shore power).
This is why lithium ion deep cycle batteries are starting to become so popular among people with RVs, boats, and even solar backup power systems. They are designed to take much more abuse than wet cell lead-acid batteries, don’t vent any corrosive gas, fully charge and discharge down to 20% of their capacity without problems, or need special charging algorithms to prevent damage like AGMs sometimes do.
Lithium-ion batteries are also lighter in weight and will not freeze or get damaged from overcharging if you leave your solar charge controller set to keep topping them off whenever sunlight is available. In fact, lithium-ion batteries can be charged at a much higher C rate without any damage which means your generator will charge them in much less time than lead-acid wet cells who only like to be charged at about 10% of their capacity per hour (or just enough to maintain charge and not boil the water and electrolyte out of them).
How Do You Maintain A RV Deep Cycle Battery?
Most lithium ion and AGM deep cycle battery banks can be left alone for several months at a time without any problems, but you should still check the electrolyte levels in each cell every few weeks during hot summer weather when they are in use to make sure none of them have boiled dry. Also, if you often take your RV out for extended periods where it will sit unused for more than 2-3 days then it’s a good idea to disconnect the main positive terminal from the house bank while it’s idle or not in use so that your vehicles starting battery doesn’t slowly run your big bank down over time.
Think of it this way, if you have a 100 amp-hour battery bank that’s made up of 12 volt batteries then each one should show about 10.5 volts when you take it off the charger and not be allowed to go below about 9 volts before recharging it again (or you risk damaging the internal plates). If your vehicle starting battery is only reading 12.6 volts because your alternator can’t keep up with how fast you’re using energy then that will slowly drain your larger house battery bank over time if they are connected which means you need to disconnect them whenever possible to prevent this (and many campgrounds charge extra fees for having too big of an AC power draw anyway).
How Do I Know If My RV Deep Cycle Battery Is Bad?
If your deep cycle batteries won’t hold a charge for more than a few days, or if they never seem to last as long as you expect them to between charges then it’s time to replace the entire battery bank. Also, any time you see white residue on the vent caps or hear gurgling sounds coming from your battery box it means that electrolyte has boiled out of one or more cells and all of those should be replaced immediately.
You can also make an emergency deep-cycle battery bank by hooking up several car batteries together in parallel, but this is only really useful if you have the means to carry around two car batteries (and keep them charged) with you at all times which is often more trouble than it’s worth.
A better idea (that I’ll be covering in an upcoming article) is to make your own 90 amp-hour lithium ion battery bank by connecting 4-5 smaller batteries together inside of a portable deep cycle battery box, but the downside to this is they are not as easily chargeable using typical charging systems like you would find on an RV or boat. What’s worse, their individual voltages will vary more widely than if they were made into one big battery bank and that makes it nearly impossible for most voltage sensitive devices to function properly (like solar panels).
How Do I Connect My Wind Turbine To My RV Deep Cycle Battery?
If you have a small 100 watt wind turbine then there’s no reason why you can’t use its output to directly charge your RV deep cycle battery bank (which is what we do) but you will need to buy a wind turbine controller that’s made for this purpose as well as a blocking diode to prevent the batteries from being charged by both your generator and wind turbine at the same time. In fact, if you have two 100 watt wind turbines then you should wire them in parallel so their voltages add together which makes it much easier to find matching wind turbine controllers and blocking diodes.
No, a better idea would be to connect your wind turbine directly into one of your inverters instead since they are designed to handle either 120 or 240 volts AC just fine as opposed to only handling 12 or 24 volts DC like most inverters tend to do. This is what we did with our first wind turbine and it works great so long as you only want to run small 120 volt loads from it since they will all share the same output voltage which will be determined by how much wind there is at any given time.
And those are some of the best RV deep cycle batteries around, anything caught your attention? It’s a good idea to ensure your product choice is entirely suitable to your personal needs and requirements. With the help of this article, now you can exam the characteristics of popular products on the market and make an informed purchase.
