  1.  WindyNation 100AH 12V AGM Deep Cycle Sealed Lead Acid Battery
  2.  Universal 12V 100AH Deep Cycle AGM Battery
  3.  Vmax AGM Deep Cycle 12V SLA Battery
  4.  Sealed Lead Acid AGM Deep Cycle RV Battery
  5.  Mighty Max 12V 100AH Deep Cycle Battery

The first thing that you need to consider when you are shopping for a deep cycle battery for your RV is what type you want. 

There are four different types, and each one has their own pros and cons. 

  • Wet Cell
  • Sealed Absorbed Glass Mat (AGM)
  • Gel Sealed deep cycle
  • Lithium Ion deep cycle

I think that gel sealed deep cycle batteries, or AGM batteries are really the best option for an RV. 

They are generally stronger, last a longer, need less maintenance, and tend to perform better for longer periods of time than other types of batteries.

Make sure that you take into consideration how much power you need your new battery to provide. 

It is simple to do as long as you are willing to add up the watts of the appliances you run. 

It’s a good idea to have a battery that offers double the capacity that you are going to need. Since most deep cell batteries have been rated in Amp hours. This is a unit that will measure the amount of energy that a battery is able to supply over a long period of time. 

Benefits to Getting the Best RV Deep Cycle Battery

When you have a deep cycle battery installed in your RV, you won’t have to worry about drawing too much power and killing your battery. 

Deep cycle batteries are a great option for any RV owner as they are so durable and long lasting.

They can be charged and discharged many times – hundreds, even – without losing their capacity to hold power. 

This means that you don’t need to worry about your battery failing you as it gets older. 

With your new RV deep cycle battery you won’t have to worry about losing power when you’re on the road. Dependable and long lasting power is the biggest benefit to selecting a deep cycle battery.

Unlike other types of RV batteries that have to be monitored to make sure that the battery doesn’t fall below a certain charge, with a deep cycle battery this is not a concern. 

I love the freedom that this offers, as you don’t have to worry about keeping a close eye on your battery.

What to Look For

When selecting a deep cycle battery, you need to pay attention to the size of the battery to make sure that it will fit in your RV. 

Additionally, you have to choose a battery with the necessary Amp hours for your needs, as this is what will determine whether or not your new battery will be able to provide you with the power that you need. 

Know your intended power needs. 

RV’ers who spend long periods of time on the road and like to boondock will need to opt for a battery that has a much larger capacity. 

On the other hand, RVers who are only using their RV to drive to a campground won’t have to choose such a large battery.

It’s also important to pay attention to how much maintenance your new battery requires. 

Sealed batteries don’t require any maintenance once they are installed correctly.

How to Use Your New RV Deep Cycle Battery

For your new deep cycle battery to work properly, it has to be installed correctly. 

Different batteries often have different mounting types, so you have to make sure that you choose a battery that can be mounted in your RV. 


It’s imperative that you make sure that there is enough air circulation around your new battery so that hydrogen does not build up. 

Too much buildup can actually cause the hydrogen to ignite and explode. 

If this happens, not only will your RV be severely damaged, but there’s a possibility of personal injury.
