Features to Consider When Purchasing an RV Battery

1. Types 

Flooded RV Battery

This is the most common type. It is known as wet cell batteries, so you have to maintain it well to keep it working appropriately. Although it holds a charge well, its design is not the toughest in terms of shock resistance and durability. So, if you use it for more difficult journeys, it may lose.

AGM Battery

The AGM stands for absorbent glass mat, which are sealed lead-acid batteries. They consist of fiberglass material, electrolytes, and a mix of sulfuric acid. Hence, the type is spill-proof. So, you can move it around without worrying about shutting down. 

Besides, as it does not contain water, it is relatively lightweight. The benefit of AGM technology is that it can hold a charge longer. From that point, it can power devices.

Gel Cell Battery

It is made from fumed silica and sulfuric acid. These materials create a gel-like substance that is immobile. This means that you can place the battery on any side. And it still holds a charge through bumpy conditions and rough travels.

2. Capacity 

People use Ah (Ampere hours) to measure the capacity of the RV battery. It can indicate the particular amount of current that the product can deliver over a period. For example, a battery with a capacity of 100Ah can deliver 100A for 1 hour. 

It is ideal to buy a high-capacity item as it can store more power as well as serve longer. When looking for a suitable capacity for your RV, you should compute your energy requirements. 

The daily power amount you need is the priority to consider. Then, you choose one that can be recharged with the help of solar power, campground electric hook-up, or a generator.

3. Battery Size

The size will alter how much power it can hold. Usually, the larger-sized ones tend to provide more power. This means that your devices can stay powered longer. But not all RVs are able to hold a larger battery.

4. Depth of Discharge 

Another aspect you should examine is the depth of discharge. It usually displays in percentage. Besides, it will show the particular power amount discharged by the item. 

If you use the lead-acid one, the depth of discharge and the life cycle are correlated. In general, if the individual cycles are more profound, the battery provides fewer cycles.

5. Voltage

This factor implies the potential electrical difference. Typically, the manufacturers design the starter batteries and deep cycle to have a 12-volt direct current (DC). In some situations, you can combine a series of 6-volt with building 12-volt batteries. 

With solar power kits, they can work with 24-volt batteries. So, you may need a power inverter. It will convert DC to AC current; then it will fit your battery perfectly.

6. Manner of Charging

Before buying the battery, you should think about whether you use solar power, generator, or shore power to charge. You can surely combine the three. But if you have had one yet, a charge controller or a smart charger is essential. 

Keep in mind that the charging profile depends on the type you are using. Besides, the controller can help you much in adjusting the current and the voltage automatically. Then, it offers protection to your battery.

7. Power at High and Low Temperatures

The capability of providing power at high and low temperatures is also advisable to check. In terms of low temperature, you ensure to buy a battery supplying power in the 0-degree environment. 

For use in high-temperature places, you have to choose the one whose ability is equal to that in low temperatures. If you use the item in a humid area, the ideal option is the one sustaining the temperature of 35 degrees. 

8. Capability of Withstanding Vibrations

When you drive your RV, the battery may suffer from vibrations or shocks due to the tough road. So, you have to buy a sturdy and robust built quality battery. Generally, it can handle vibrations, and it should be shock-resistant.
