Vmaxtanks Vmaxslr125 AGM Deep Cycle SLA Rechargeable Battery

Tough performer

Some consider this one to be the top RV battery out there in the market right now and for good reasons. 

While it is not easy to confirm this, we do know that when it comes to performance and long lifespan, this is one that you should not overlook. This is definitively a high-quality battery that can guarantee a life of 8-10 years in float mode.

When you look at the Vmaxtanks Vmaxslr125 AGM Deep Cycle SLA Rechargeable Battery, probably the first thing that strikes you is its heavy-duty design.

This gives you the confidence that it is definitively a strong performer that will not leave you behind. It is an investment that will pay off.

So let us start with it heavy-duty performance. This basically means that is a tough and strong one that will keep your home up and running even if you bring it to the harshest environment. You will see later on in this article how temperature can affect the performance of an RV battery. As a little head-start, you should know that very cold temperatures can make a battery go dead.

The Vmaxtanks Vmaxslr125 AGM Deep Cycle SLA Rechargeable Battery has a 12-V power and a 125 AH rating.

Still, in the heavy-duty department, this battery has a military design, which is held by its custom-made plates. The manufacturers of this AGM deep cycle actually boast about this and the truth is that it keeps its promise of quality. We will be taking a look at what AGM batteries are with more detail, but these batteries do not have any roaming fluids such as battery acid and they require a minimal vent. 

We do recommend you make sure it has enough space within your RV as it can still build up some explosive hydrogen gas. As with other dangerous gases and fumes, you can rest assured that there is no such risk on this one. This rechargeable battery is designed to for up to 99% recombination capacity, so you also got that to ensure near-to-zero gas buildup.

  • Customized, military-grade plates
  • This battery is really tough and durable.
  • It will deliver constant performance without a glitch.
  • Easy to install.
  • It is pretty heavy.
The Good/What I like

It seems like everything is to be like about this battery. When you read through all the specs that come with it, it makes it feel like a complete battery. That is because it indeed is a complete battery. It delivers excellent performance, even in conditions of extreme temperatures and harsh conditions. These conditions would take its toll on cheaper batteries such as marine batteries, for example.

We love its military grade design and heavy-duty output. The fact that they are safe and eco-friendly is also a big plus for them. One of the things that we like the most is that they come with a charge when you get them and they are easy to install on your RV.

The Bad/What I don't like

Probably the one thing that we don’t like about it actually has to do with the fact that they perform heavily, and that is their weight. These are easy to install and all, but because they are pretty heavy, handling them can be a bit of turn-off. However, you can use help if you don’t want to risk your back. This is something that will definitively not affect your perception of the quality of the battery and you will overlook it once you experience them.

Please make sure you are able to enforce the company’s warranty in case something goes wrong. Make sure you are using these batteries properly and under the correct setup.

D34M BlueTop Starting and Deep Cycle Marine Battery

Our Most Reliable Choice

As you read the name of this battery perhaps one word that comes to mind is versatility. You got that one right. This battery is also considered one of the best-rated batteries this year. Customers regard it as being highly reliable. You see, it works as a starting battery and as a deep cycle marine battery.

Keep in mind that the fact that it is a marine battery, the life expectancy is 2 years, depending on how much you use your RV.

Another thing to consider is to make sure that you select the battery with the blue cover and grey case as this is the one with the dual purpose.

Let us begin with the basic spec: it is an AGM battery with 12-V capacity.

This battery has a design that makes it more practically not only in positioning in your RV but also to provide higher power than the traditionally-designed batteries. Speaking of higher power, these batteries can also be recharged for a quite large number of times without it losing its capacity.

The inside of the battery features individual spiral-wound cells within two lead plates coated in lead oxide. This is a unique design that out-performs the traditional flat-plate design. To maintain quality and performance it uses custom automated cell-winding machines. This is probably very technical talk, but you will surely get to know how all of it translates into exceptional performance.

The body of the battery is strong and capable of enduring all types of weather. It is well-endowed to resist vibrations. As we said earlier, at very low temperatures, batteries will usually die and not get your RV started. Remember how we mentioned reliability? This battery will start your engine in the coldest temperature. No need for manual fixing.

This battery is specially designed for those who do not want to worry about their batteries as they are on the road. It has a strong cranking and it is free of maintenance.

Its vibrations resistant characteristics make it capable of resisting not only vibrations but impacts and shocks. It is probably one of the most durable RV batteries out there. This resistance also allows it to last for a longer period of time.

When it comes to installation, there is no major issue there, it is actually pretty easy. How to position it? However, is best for your RV’s configuration as it is spill proof.

Optima is a manufacturer that boasts being always pushing the limits of what is technologically possible. This explains the innovative design that makes the charging time much faster and the number of charges more durable. Besides this, the D34M blue top starting and deep cycle marine battery has a 2-hr reserve capacity when set on high power. Thanks to this, its power will not only run on your vehicle’s engine but will also keep your appliances up and running.

Users have actually reported this battery to be able to hold more than half its charge even after 6-8 hours of running. That is pretty impressive for an RV battery.

Another advantage of such good recharging and charge abilities is that even when you have your RV resting and you live in the desert, you will surely have a battery ready to fire up your engine and your RV. This is also enforced by its 750 cold cranking amps.


  • Unique design makes it easier to install
  • It resists vibrations, shock, and impact
  • Its strong body makes it weather-resistant
  • Features a 2-hour reserve capacity.
  • Great charging abilities and higher power
  • We believe that for a deep cycle battery with a life not that long, the battery is rather expensive.
The Good/What I like

This battery is definitively our king when it comes to reliability. Very few batteries will be able to store charge so effectively. It can be charged a lot more times than any other marine battery. It also makes us smile when we see how easy it is to install. You can basically place it virtually any position as it will not spill and is maintenance-free. We also love that it is a tough one that resists vibrations, shocks, and impacts.

The Bad/What I don't like

What we probably don’t like about the D34M blue top starting and deep cycle marine battery is that they don’t make a heavy duty and exclusive deep cycle one. This battery would be great if its deep cycle abilities were more heavy-duty.

VMAX857 AGM Battery

Top Budget Option

This is a deep cycle AGM battery that will impress you with its performance, especially after you see the price tag. This makes it our top budget choice. It really has some awesome specs.

The VMAX857 AGM battery has an internal physical and chemical structure that provides it with very special and unique abilities. For starters, it is equipped with cell plates and electrolyte that makes it far superior to the wet lead acid batteries.

These VMAX plates have their specially designed absorbed glass mat (AGM) between them, which contributes to the many physical and chemical advantages of this battery.  This design also makes it resistant to shock and vibrations.

Worried about spilling or leaks? There is no reason for that. The electrolyte we mentioned is a liquid but it is absorbed by the AGM. If to this you add tough tank seals that safely seal and protect the plates, you got yourself a battery that requires no maintenance at all.  Just install and enjoy. 

Besides everything above, we also noticed that the battery has a special structure that makes it capable of withstanding deep discharges and makes charging fast. 

We perhaps should have mentioned this earlier given that it is probably the first thing you will notice about it and this is the fact that it is lightweight. We are talking about 25 pounds only, which goes a long way at reducing load weight on your RV. It also has a rather small volume, making it very convenient when it comes to installing them in the battery compartment in your RV. 

One of the things that this battery is better known for is the long-life span. In the case of an RV, you can get a great worry-free performance to power up your appliances. The battery also features a 75-minute reserve capacity.

For an extra margin of performance, the VMAX857 AGM Battery also features heavy-duty grids. This is also helpful at expanding the service life of the battery. It is actually nice that this battery operates while requiring almost no maintenance.

When we refer to no maintenance, we basically mean that there is no need to add water to the VMAX tanks nor checking specific gravity or the electrolyte. All you need to do is to install properly and let it run your house. 

In overall, the quality after the brand VMAX is backed up by the use of thicker plates, which results in higher quality and longer lasting batteries. The extra durable and tough outer case includes a standard carrying handle made of ABS plastic. 

Your expression after using this battery is that there is a lot of power in such a small package. If you are looking for great performance, easy installation, and vibration and shock resistance, for a really great price, this is well worth looking at. 

  • Lightweight and small-sized.
  • Built to last a long time.
  • A sturdy ABS plastic closing.
  • Features a liquid electrolyte that is absorbed by the AGM plates.
  • It requires a special charger.
The Good/What I like

We definitively enjoy the lightweight and small size of this powerful battery. But don’t let the size fool you as you have seen all the amazing specifications. It is capable of providing 12 V of potential difference, which when combined with others in your RV, will give you the power you need to run uninterrupted. 

We like that it is really friendly when it comes to charging. It holds to a charge a decent amount of time and has a 75-minute reserve capacity. It has the appropriate size and one of the best performances. Its small size means that it does not take much space in your RV’s battery compartment. 

The Bad/What I don't like

This is our selection for budget battery. However, we believe it could still improve this price to make it more competitive. Nevertheless, we believe that it is still a great investment.  Oh, and we do not like the fact that it needs a special charger, which takes points off being practical. But then, this special charger is what it needs to keep the life of the battery optimal. 

Odyssey PC680 Battery

Best Bang For The Buck 

Typical deep-cycle batteries have a life of 6-8 years, with some exceptions. The Odyssey PC680 Battery made it to our list with honors and with a span of amazing features that make it a great option for powering your RV.

When you see this battery, probably the first thing you notice is its nice color. As you come closer, you notice that the casing is pretty strong, sturdy, and it looks durable. This rugged structure, in fact, makes it capable of withstanding a pounding or two.

Let us begin with some basics. First, this battery has a CCA of 170, a 70% longer life cycle (according to manufacturer-we have not been able to prove that) than conventional batteries, and 3-10 years of service life. Notice, though, that the warranty is only open for 2 years.

Another great feature of this battery is also how fast it can be recharged. It will usually take 4-6 hours to get it fully packed with electrons. Just remember that this time is an approximate and the real charging time will depend on the temperature and age of the battery mostly.

When it comes to voltage, this RV battery has a great performing act. The voltage provided is high and yet stable, even if used for a long time. The body of the Odyssey PC680 is pretty rugged but it is also pretty flexible, which helps to make installation easier. 

It makes you feel confident that this battery is capable of withstanding a good beating, which comes with the territory. Other batteries would succumb at the number of vibrations and beatings this battery can still take. 

We know that one of your concerns in batteries is if they will spill and fall over your electrodes rendering them useless. Thanks to the AGM technology, the fluid electrolyte that used to be a concern for leaking batteries, is now absorbed by the AGM plates, which eliminates the risk for spilling. So the chances of this battery leaking are very close to zero.

Let’s focus on the power of this battery a little bit. The battery is built with pure virgin lead plates that widen up the surface area. This design that includes electrolyte-absorbing AGM avoids corrosion, increases conductivity, and tin terminals provide this battery with a high efficiency when it comes to holding on to their charge.

A highly stable voltage makes it pretty long-lasting. Furthermore, the charging time is really quick and it has a rather long cycle life. 

Keep in mind that this is a rough one. It is able to not only withstand tough vibrations but it will also cope in harsh environments, even when it switches from very hot to very cold. 

  • It has a relatively longer life cycle.
  • Charging time is pretty short. We are talking about 4-6 hours.
  • It will not leak or spill.
  • The design is both flexible and rugged.
  • It withstands impacts, vibrations, and shocks.
  • A non-universal design can make it difficult to use in some RVs.
The Good/What I like

We definitively enjoy the flexibility and ruggedness of this battery’s external casing. This speaks about durability and the ability to stand shocks, which, when it comes to an RV, is part of the package. The great interior design of this battery is the one responsible for such a powerful delivery and an efficient storage. 

Despite having a liquid electrolyte, this battery will not spill thanks to the absorbing AGM. The structure of the plates makes it easy to recycle. We absolutely love its long life cycle. Very importantly, we appreciate the short charging time.  This is definitively one that will perform smoothly during those long RV camping trips.

The Bad/What I don't like

We did notice that the battery is unusually thin. We get that the manufacturers are trying to make it more effective, which is great. However, it might become an issue as this is not a universal fitting so some adjustments will need to be made in the battery compartment of your RV. Make sure that you can actually make any necessary adaptations so that you can make these ones fit.

Universal Deep Cycle AGM Battery

Best Bang For The Buck 

There are two words that you can use to describe Universal Power Group’s UB121000-45978 12V 100AH deep cycle AGM battery and those are flexibility and versatility. This battery is capable of servicing a variety of vehicles.

We know we are looking for RVs here only, but just in case, this versatile battery can be used for a boat, scooters, wheelchairs, golf carts, and any other vehicle requiring a powerful source of electrical power. 

This convenient and reliable battery can be placed on this variety of vehicles in any position necessary as it is spill proof. 

Since it does not need maintenance, this is probably one of the most user-friendly batteries you will find in the market. It is widely known for being easy to install and set up.

Taking too many bumpy roads and blows in the country. Not a problem. This battery is capable of resisting most shocks and vibrations and still perform in optimal conditions.

The battery is perfectly sealed and it uses AMG technology used in many batteries today, which provides a greater efficiency and prevents any spills as the liquid is being absorbed. 

This deep cycle battery has the advantage of a 100-ampere-hour rating, ensuring a long and functional lifespan. The storage capacity is altogether impressive and it works well with a solar charging system. The batteries will work well given that you connect them in parallel. 

It is a strong battery with a solid construction. The rope and handle included make its transportation easy and comfortable. The battery has a useful life of around 3-6 years depending on storage and frequency of use, just like any other RV battery.

The design of this battery lets you regulate and control its performance with the aid of a valve. A really tough one, there is nothing to be sorry about when you install this option on your RV. 

  • It has a pretty well deep cycling well.
  • It is versatile in the sense that you can use it for many other vehicles, not only RV.
  • Energy efficiency. This is good for the environment, too.
  • It requires almost zero maintenance.
  • It is heavier than other batteries.
The Good/What I like

One thing that we like about batteries is that they save us time and work. We just want to put it up, connect the wires and never hear of it again. This is what we love about Universal UB121000. It offers the flexibility of allowing you to install it in any position on your RV. This is thanks to the fact that it is spill proof and it does not really require maintenance.

We should also speak of versatility, which we also love. This battery can easily be dismounted and use in a variety of vehicles that we mentioned before. Of course, the tough design makes it capable of withstanding some serious blows.  

The Bad/What I don't like

When we were going to test this battery on weight, we found out that, even when it is one of the best out there, it is plenty heavy. In fact, it is heavier than most batteries.  Thankfully, it comes with a practical rope that makes it easier to handle. 

But the rope might not have the optimal quality and might break. This becomes a problem as the battery, with 65 lb in weight, will be hard to install and to store. But this should not be an issue as you will not really need to be transporting your battery that much. It can maintain its charge and quality even if we do not use them regularly.  

Buyer's Guide

Now let’s take a look at everything you need to know to ensure that you buy the best battery for your RV. There are many aspects of the battery and of your recreational vehicle that you need to take into account, so it is better for you to make an educated decision instead of relying on propaganda or the price along.

Types of Batteries

You noticed that we mentioned two basic types of battery. One is the engine’s battery, which is basically the one that you need to start your engine.  The other type is the one you are going to use to power your RV. This is the deep cycle battery. 

An engine battery has the same function as the battery in your car, only it is larger than the one in your car. It needs to be able to send power to the engine to make it start. In technical terms, it needs a larger CCA (Cold Cranking Amps) rating. This refers to the ability of a battery to provide power even after a long period of inactivity. 

Now, the house battery is different from the engine battery in that it needs to be providing power constantly. So, these RV house batteries undergo what is known as a deep cycling since they are usually fully discharged before they are charged again. These deep cycle batteries usually last four times as much as the engine battery.

In summary, the cheapest kind of batteries are the 12 V used to start the engine. These are great at what they do but they will not last as an RV house battery. Hence, they are the cheapest type.

Marine batteries are those that can work as both engine and house batteries. They are not the greatest at either job but they get it done. As a house RV battery, these ones will last about two years, depending on how often you use your RV.

Then there are gel batteries, which are a great choice as a deep cycle battery. Most batteries have a lead solution acting as an electrolyte. You need to fill it up once in a while since some of it is lost during every charge. Manufacturers have solved this by sealing their batteries and only allowing a little vent. It is not the best for a deep-cycle battery but it drops maintenance needs and keeps durability. 

Many users love the more rugged golf batteries. These are highly durable and usually last from 7 to 10 years. Of course, these type of batteries is more expensive. 

You can see how your type of activity will also help decide what kind of battery you need. If you will just go camping away to your summer home twice a year, maybe a marine battery will do the trick. If you take it for long trips every once in a while, you are better off with a more robust and lasting battery. 

Characteristic of an RV Deep cycle battery

Let’s get down to better understanding how an RV deep cycle battery is supposed to work. This will help you know what to expect and to enforce the battery’s warranty if they don’t deliver the way you expected to. 

Speaking of which, we strongly recommend you become savvy on everything you can related to batteries and electricity. Include the practical and theoretical stuff, such as parallel circuits, circuits in series, Ohm’s Law, etc. Besides having a better understanding of how your batteries work, you will be able to genuinely go back and forth with the manufacturer in case you have a complaint.

This will depend on the manufacturer but an RD deep cycle battery is designed to discharge between 50% to 70% of its capacity. When you recharge a battery, energy in the form of a rush of electrons (which is what electricity is made of) is re-entered into the bank and the cycle starts over.

A starting battery has very thing plates, whereas a deep cycle one has thicker plates. They are not spongy but rather solid. This reduces their surface area and therefore their instant power is not as much as that of a starting battery. 

Experts usually advise you to get a true deep cycle battery instead of a dual-use one for your RV. This will provide a better performance. The Optima battery we proposed is a nice exception to this as it performs equally great in almost any type of RV. This is one of the best RV deep cycle batteries out there.

Types of Deep Cycle Batteries

Very briefly, let’s describe the three main types of deep cycle batteries.  

  • Flooded Lead Acid
    These deep cycle batteries are also known as wet batteries. They are the most popular for RV applications. They are called that because the plates are completely submerged in an electrolyte composed of sulfuric acid and water. During recharging, a chemical reaction that releases hydrogen and oxygen takes place due to a process called electrolysis. This is why these batteries have vents. Hydrogen is explosive so your RVs compartment must also have vents to let it free. If you note, we did not include these in our reviews. Basically, because they can leak, they need to be upright and require maintenance.
  • AGM
    These are an absolute improvement to the flooded lead. They are stronger, tougher, and require less maintenance than the flooded lead acid ones. The internal structure is basically the same except for the absorbent glass matt, which absorbs the acid, preventing it from moving randomly inside the battery. These batteries last longer but they are more sensitive to overcharging.
  • Gel
    They are still better than flooded lead acid ones. As the name suggests, the acid inside these batteries is gelled, which makes the recharging process slower than flooded cell and AGM. So, you must be careful not to charge them too fast. They are not really the best option for your RV.

The final decision on what the best choice for you is, then, dependable on your particular needs, and the type of use you will be giving to your RV. Always decide to make a good investment when it comes to the battery of your RV. This is the power plant that keeps the heart pumping. 

To make sure that your batteries last in good condition through their useful life, you need to get the best quality ones you can. This is when it gets tricky since, of course, there are many options out there. Just like with many things, sometimes (but not always) the price is a good indication of the quality of a battery just like some of the best rated RV generators on the market.

But there are also less expensive options that we have seen deliver just like a premium much more expensive one. This is where you must have a good eye. You have seen the several options we placed for you to look at as the best choices out there. These might help you decide which is the best option for you.

Making an educated decision involves knowing as much as there is needed about how RV batteries work. This will help you make the best decisions when it comes to troubleshooting your battery and/or your connection. Once you have an RV battery we also recommend investing in the best solar panels for RV

From what we have seen, experiences among users vary. Always keep the warranty close to you in case your battery does not perform as announced by the seller. 

The first obvious thing that you need to know is that your engine battery and your house batteries are different. The engine battery, just like the one in your car, is the one your vehicle uses to generate the spark that starts the engine. Your home batteries are the ones that will be powering the appliances inside your RV.
