Best RV Battery

Are you searching for the best RV battery?

Whether you need a replacement or a backup rv battery, it is important to select a high quality battery that will not leave stranded on the road.

I have reviewed the most popular RV batteries on the market and after reading this article you will know my recommendations.

Check out the quick list below for links to customer reviews and prices for my picks, or read on for the full reviews:

  1.  Renogy 12V 100AH Rechargeable Deep Cycle Pure Gel Battery
  2.  Renogy Deep Cycle AGM Battery 1V 100AH
  3.  Universal UB121000-45978 Deep Cycle AGM Battery
  4.  DieHard 38217 Group Advanced Gold AGM Battery
  5.  WindyNation 100AH 12V AGM Deep Cycle Sealed Lead Acid Battery

There are multiple battery options and they each come with their own advantages and disadvantages. 

It’s important for RV’ers to know the difference between marine batteries, deep-cycle batteries, and flooded-cell batteries so that they can easily choose the right ones for your intended use.

If you only need a battery to help you get from your home to the campground, then you may be able to use a marine battery. 

If you want to boondock, however, you will need a battery that has a larger capacity and will be able to provide you with more power so that you can easily run all of your appliances without problems.

Benefits of Having a High Quality RV Battery

When properly installed and maintained, an RV battery is a great way to make sure that you have power when on the road. 

Be able to run your appliances is a must in order to stay comfortable while using your RV. 

With a high quality RV battery, you won’t need to worry about having power when you are in between your home and a campsite.

What to Look For

You need to consider the life cycle of the battery you select. 

This will play a huge role in how long your battery will last, as every charging and recharging cycle will cause your battery life to reduce. 

Opting for a battery that is designed for deep cycle use will mean that you won’t have to worry about it failing as quickly as other options.

Also make sure that you see how much maintenance the battery that you’re considering requires. 

Some types of batteries require added water, while sealed batteries do not require any maintenance. 

Make sure that you know how much time and effort you are willing to spend on taking care of your batteries so that you can choose the right one for you.

How to Best Use Your New RV Battery

Before you try to hook up your new RV battery, you need to make sure that you understand how to correctly install it.

I find that every RV battery has different mounting needs, which is why you will need to do your research on the type of battery that you have chosen for your RV. 

This will ensure that you mount it correctly and that you don’t have problems with your battery when you are on the road.

While some RVers think that buying new batteries on a regular basis is normal, it isn’t. 

These precautions will help you get the most use out of your new battery.

First, be aware that you don’t want to let your battery go below a 50% charge

Once your battery goes below 20% it can become damaged and may never be able to function back at 100% again. 

This will be frustrating and expensive. 

Make sure that you monitor the voltage of your RV battery so that you don’t experience problems with your appliances not working correctly or your battery failing. 

If you have an RV with a solar panel or inverter, then you can easily monitor the charge state and voltage on the battery monitor. 

Otherwise, I recommend using a digital voltmeter.

The most common reason that RV batteries fail is that they have been overcharged or undercharged. 

When you don’t fully recharge your battery between cycles, then the sulfate material inside the battery will harden into crystals, which can ruin your battery. 

On the other hand, if you overcharge your battery on a regular basis, then you can suffer from plate corrosion, as well as severe water loss. 

Now, let’s get to the best RV battery recommendations.
