Written by Liam Jaxon / Fact-checked by David Rowan

A deep cycle battery can supply power to run lights, fish finder, radios and other essential electrical elements even without 110 volt power supply. So it became the most important source of power supply at any outdoor activity. 

But when I had to buy a battery for a RV, the first question that came to my mind was- what features make a deep cycle battery good in quality? Should I look for capacity or voltage or ampere hour! Which one makes it better!

deep cycle rv batteries (how to choose right type)

After a long research, I was able to find the one I needed. And indeed, I am happy with that one. But I found many of you get confused like me selecting this.

There are some kinds of batteries to look over, and here to enable you to pick the correct RV battery to ensure you are not left in obscurity.

For selecting a reliable battery, I highly recommend picking the one which can give out a high amount of power within a few seconds.

Still confused!? Don’t worry, I have summarized my experience to give you a proper idea about some great batteries for RV and the way you can choose them.

Benefits of the Perfect RV Battery

benefits of the rv battery

Deep cycle rv battery should be able to supply your RV with both cranking power and power for running the RV’s appliances and lights. The cranking power of the battery varies at different temperatures. It is lowest at zero degrees Fahrenheit, and bets at about 80 degrees Fahrenheit. The reason behind that is that batteries perform better at higher temperatures than they do at lower temperatures. The higher the cranking rating, the better the battery will perform when starting your RV engine. You won’t find yourself unable to start your RV when you need to the most.

The power required to run the appliances depends on the reserve capacity of the battery and the ampere –hour ratings. The reserve capacity rating tells you how long the battery can power your equipment when supplying a constant current of 25 amperes. The best RV battery will have a higher rating. The ampere-hour rating tells you how much power the battery can give during a 20 hour period. The higher the rating, the better the RV battery will perform. You will not run out of power when you least expect to.

What to Look Before Buying an RV Battery

You have to consider several features when buying a battery. These features are not limited to just a deep cycle rv battery; they also apply to other battery applications as well.

Cold Cranking Amperes

This is the amperes that the battery will supply when the starting motor is drawing power from it at a temperature of zero degrees Fahrenheit. This rating is important if you will need to use your RV during winter. Battery performance gets degraded at lower temperatures. Therefore a higher CCA rating assures you the battery will su0ply enough power to start the engine during cold seasons.

Cranking Amperes

This is the power that the battery will supply when the battery is operating at temperatures of around 35 degrees Fahrenheit. This rating has the same importance as the CCA. It tells you how the battery will perform at temperatures above the freezing point of water. The better the CCA rating is, the better the RV battery’s starting performance.

Ampere-Hour Rating

This is the amount of power that a battery will be able to deliver over a period of say 20 hours. The power is measured in the current supplied. So a battery rated at 240AH will be able to supply an average 12 amperes, continuously for 20 hours.

Reserve Capacity

This is the amount of power, which the battery can give for a specified period. It is measured in minutes. The common power output used is 25 amperes. So a battery rated RC 125, will supply 25 amperes for 125 minutes, then the voltage will drop below 10.5 volts.

Resistance to Vibration and Shocks

If a battery has an Absorbed Glass Matt construction, it means that it will be able to withstand vibrations and shocks well compared to a flooded lead acid battery. It can, therefore, supply the RV with power without a drop in performance even when you go off-road. A flooded battery cannot, however, do that without performance degradation.

Editors Note

When choosing the RV battery, we look at the common needs of an RV. An RV will require continuous power for its onboard electronic equipment. It will also require a starting power when you want to move it or you are traveling. People are embracing renewable energy; you, therefore, have to know if the battery can be recharged using solar power. Not every battery can recharge from solar panels without wastage.

The best deep cycle batteries also happen to be the best when using solar panels to recharge. But to also take care of the RV’s starting needs, we have to take into account its need for huge current draws for a short period. That is typically about 30 seconds. With that in mind, we can look at a battery’s features and match them with those of an RV’s power requirements. We, therefore, have to consider a battery’s Cold Cranking Amperes, Cranking Amperes, Reserve Capacity, and Ampere-Hour rating.


Do these Types of Batteries Contain Enough Power to Start up a 250 Horse Cummins Diesel?

No, they are not made as a starting battery. They deliver power slowly and continuously and they provide it steady for a long time. They are designed for it. If you try to use it as a starting battery, then it can be damaged. If you want a starting battery, then you may find this helpful, our Jump Starter Lithium Ion Battery Review.

How Long are the Batteries Capable to Power up a Trolling Motor Like Minn Kota 30 lb with 2 Average Sized Adults on Board?

Actually this depends on the Volts & AH. We can’t tell specifically but we can give you an example like a 12 Volts 35 AH can hold up a 40 lb Minn Kota on a 10.5 foot Porta Bote for a few hours. It also depends on the speeds.

Are they Universal Batteries? Do I Need an Additional Charger?

The batteries are especially designed as marine batteries. They are the best in this section. But you also can use it for anything else. But for that, you need a special charger. If you use the regular charger, then you will kill your battery.

Should I Completely Discharge the Battery the First Few Times?

No, there is no need to do that. A RV deep cycle battery does not require any complete discharge at any time in its service life at all. But if you want, then you can do that.

Do the Cold and Heat Damage the Battery?

Usually No, but overheating or under cold can damage your battery.  Both of these conditions can reduce your battery life. For an example, we may tell that a fully charged battery at 80°F or 26°C should operate with 100% efficiency, at 32°F or 0°C, it turns with 65% efficiency and at 0°F or -17.8°C, it decreases  with 40% efficiency.

To What Extent do RV Deep Cycle Batteries Last? 

Deep cycle batteries and RV house batteries that are intended to store a lot of intensity so they can work over significant lots of time. Deep cycle batteries can last as long as five years whenever kept up appropriately.

Should You Leave Your RV Connected All the Time?

Indeed, you can keep your RV connected all the time. But you should check the electrolyte levels on your batteries at any rate once per month to ensure that they’re not dry or have gone low.

Does a Generator Charge an RV Battery? 

Inner Generator: The generator in an RV utilizes a converter, which changes 120 volts to12 volts, and isn’t intended to be a battery charger. The fundamental utilization of the converter is to give the 12-volt capacity to your apparatus while connected to an A/C outlet. Running the generator will charge the house batteries at a moderate rate. 

Maintenance Tips

Your battery will provide you with great power delivery and last for a longer period if you take proper care of your battery. The battery maintenance extends the battery life and keeps the performance. Here are some tips so that you can take proper care and continuously get the great service from your battery-

  • Charge your battery properly. Always keep the charge of your RV battery above 50%. If it goes below 50% anytime, charge it immediately.
  • Do not overcharge your battery. Overcharging may reduce the lifespan of your battery.
  • Charge as soon as possible after use.
  • Do not charge your battery with over or under voltage.
  • Always monitor the voltage the battery gives out by using a digital voltmeter or the built-in monitor. It will help you to take proper steps to avoid damage.
  • Check your battery on a daily basis. It will help you to find out any sign of damage or leakage. Check the battery by a professional once a week to avoid any big trouble.
  • Rinsing with water can help the battery to lessen the chance of overheating.
  • Be careful while handling the battery. Always use safety gloves and eye protective glasses to avoid contact with fluids.
  • Clean the out surface when it gets too much dirt.

Final Verdict

If you plan camping or traveling frequently, buying the best RV battery can be a great investment. You and your family or friends can have an amazing trip without any kind of interruption.

Though choosing the best one is a little bit tricky, our guideline can help you to find out what suits your needs. Don’t forget to consider ampere-hour and reverse capacity. Because these two have a huge impact on the battery’s performance.

After purchasing, your battery needs proper maintenance like- charging properly with a good charger, monitoring the voltage, fluid maintenance, cleaning and so on.

Because a good RV battery with proper caring can give you a great experience of the planned trip.
