The difference of RV Battery with Other Batteries
1. CCA Value
The CCA or cold cranking amps is an industry standard metric for batteries that show you how much current the battery is able to provide when the temperature is exactly 0°F.
The higher the CCA value, the more operational the battery is in cold temperatures. Therefore, this is an important value to consider especially for those who drive their vehicles in very cold weathers.
When compared to other types of batteries, the RV battery generally has a higher CCA value, especially compared to the traditional lead-acid battery.
Therefore, the RV battery will have no problem providing sufficient current in both hot and cold weathers.
2. Deep Cycling
The deep cycling battery is able to store more power for a longer period of time. Therefore, this type of battery has a lower discharge rate when compared to a regular lead-acid battery.
The deep cycling that is still used around 95% of battery acid with tiny fiberglass plates stacked one on top of another.
What this does is increase the surface area and allows the deep cycling RV battery to store more power and ability to provide current to every electrical component in the RV.
Moreover, one major difference between the deep cycling battery over the regular car battery is that you need to charge and discharge the deep cycling battery a few times before you can start using it.
3. High-temperature Variation
A high temperature usually affects the charging and discharge rate of a regular lead-acid battery. This type of battery will have a higher discharge rate when the temperature is high.
This is not a problem with the RV battery since it is equipped with technologies that make it more versatile and efficient, able to have a higher reserve capacity even in higher or lower temperatures.

As its name suggests, it uses a combination of lead metal and sulfuric acid to produce electricity that powers your vehicle.
The lead-acid battery is not as heavy duty or powerful as a deep cycle battery but it is significantly cheaper and as long as you do not need to power demanding electric devices, it is more than enough to start a vehicle like an RV and power basic RV devices.
How to Buy the Best RV Battery
1. Different types of RV battery
There are different types of RV batteries on the market. Each has their own advantages and disadvantages.
Wet Cell: Probably the most affordable type of RV battery on the market. Wet cell batteries use distilled water as the electrolyte and can easily be replaced for maintenance as it has open caps.
This type of battery does not produce a powerful current but it is more than sufficient to power on the RV and some basic electric appliances within the RV.
AGM: The AGM battery is a military grade battery that is made of thin fiberglass sheets stacked one on top of another and then connected with a conductive wire mat.
Since the fiberglass is also close together, the AGM battery is resistant to vibrations and can be mounted in any position.
Furthermore, since AGM uses a sealed container, the risk of acid leaking out of the battery is almost nonexistent.
Gel: The gel battery uses a thick pace as the electrolyte. It is also a sealed container battery and maintenance-free as well. One of the biggest advantages of the gel battery is its very fast charging time.
If you drive your RV for short distances or have a small alternator in your RV, then the gel battery is an excellent model to consider because of its short recharge time.
2. Capacity
Basically, the capacity will dictate how powerful and heavy duty the battery is. The higher the amp per hour or AH is rated at, the more electricity it will be able to provide for one hour.
If you have many demanding electric devices in your RV, then going with a higher capacity battery is always the best choice.
Additionally, a higher capacity battery will have a lower discharge rate but will require a longer period of time for the alternator to charge.
If you do not power on your RV often or drive long distances with your vehicle, then it is probably wiser to go with a lower capacity RV battery as your alternator may not have time to fully recharge the battery.
For basic RV applications, a battery with a capacity of 44 AH is the bare minimum you may want to go with.
For heavy-duty applications, or if your RV has many electric devices, then you may want to go with a battery that has a capacity of at least 100 Amps per hour to ensure that it is powerful enough to provide current for those demanding devices.
3. Voltage
When it comes to the vehicle battery, 12 V is generally the default value. This voltage will be able to power any type of vehicle. However, when operating an RV, you may need a different type of voltage because very few heavy-duty electric devices run on 12 V.
Therefore, you may need an inverter that will convert the 12 V into 110 V or 240 V depending on the power rating of your electric device. If that is the case, then you may choose to go with a 24 V battery instead of a 12 V since you will have a higher efficiency margin when converting 24 V to 110 V.
4. Cold Cranking Amps
The cold cranking amps or CCA value will tell you if the battery is able to withstand cold temperatures or not. The higher the CCA value, the more current the battery will be able to send in low temperatures, generally below zero.
This is an important aspect to consider especially if you use your RV in cold regions. Considering that the battery in the RV is usually found outside of the vehicle and exposed to harsh the temperatures than the inside of the RV.
Therefore, if you use your RV in cold areas, keep an eye out for an RV battery with the CCA value of 500 or higher. This will ensure that you will have no problem starting your battery in very cold temperatures.
5. Cycle Life
The cycle life basically means how many times a battery can fully charge, discharge at 80% and then recharge again. Of course, the higher the number the better the battery as it will indicate a model that can be used as a heavy-duty battery.
6. Shock and Vibration Resistance
If you normally drive in rough terrains where your RV and hence, the battery will undergo a lot of vibrations, then it is important to choose an RV battery that has good resistance to vibrations.
Top-rated RV batteries like AGM batteries are normally excellent choices for this because the fiberglass sheets in the AGM battery are so close together than it virtually eliminates vibrations and shocks inside the battery. This makes the battery more durable and long-lasting, even when used for an extended period of time in rough terrains.
7. Connector studs
The connector studs on the battery are what connects to the alligator clips of your RV electrical system. There are basically 2 types of studs, a big one in a small one. You need to ensure that you have the right size of the stud on your battery before you make the purchase.
Additionally, ensure that the connector studs are corrosion-free and will not rust over time. Usually, a metal like stainless steel for the studs is a strong guarantee for stud durability and excellent electrical conductivity.
Conclusion
As we have seen, the RV battery is essentially a heavy-duty battery that is powerful enough to provide sufficient current to all your RV electrical devices, as well to the RV as well.
This type of battery usually uses a different and more efficient technology when compared to the regular lead-acid car battery. The only downside is that the RV battery is usually a little bit more expensive than the traditional lead-acid battery. However, they are so much worth it in the long-term.
Finally, if you have read our RV battery review above and still undecided on which RV battery model to go with, we recommend you read the review again.
