Factors to Consider When Buying the Best RV Battery for Boondocking

For RVers, boondocking can mean various things. Some RVers associate the term with having an overnight stay in an RV, regardless of whether it is a Walmart parking lot or any other place. Another type is camping in an RV park.

This is where you set up a camp in an RV campground or any other campground to spend some nights out –  escaping from the city hustle to experience outdoors and nature while still enjoying access to water, electricity, and sewer system.

One more type of boondocking is staying at campsites that are still in the development process. There, you find a safe but undeveloped space to experience the outdoors.

There is no time frame since the duration of boondocking is up to the RVer. However, one thing is sure – you need a dependable, reliable battery for a smoother, safer, and enjoyable boondocking experience. 

Here are the essential points to look for when buying the best RV battery for boondocking,

Some RVers prefer connecting multiple batteries, such as two 6V batteries, to have a total of 12V power for their rig. However, the common choice is a 12V battery, regardless of whether it is a deep cycle or a starter battery.

2. Capacity

It is a must to take the battery’s capacity before making the final decision. The amp-hour of the battery is a crucial factor that must be considered since it determines how much power you can store to use it later.

In simple words, if a battery has a 100Ah rating, it means the battery can provide 100-amps for an entire hour.

While considering the capacity of the battery, determine the power requirements that your vehicle is compatible with. Make sure to check the onboard appliances, including devices, gadgets, tools, household items, and others that you would require to plug in or charge for use.

For a rig that is used to be boondocking, it is recommended to find deep cell batteries with higher capacity. The reason is these batteries are more stable when being used as a power source.

Furthermore, another thing to consider is the battery’s charging versatility. If you want an RV battery specifically for boondocking, select a battery that can be easily charged in RV’s solar panel, a generator, a battery charger, or the RV campground’s charging system.

The best RV boondocking battery should be capable of utilizing shore power, generator, and solar power.

3. Performance

The third factor to look for when choosing the best RV battery for boondocking is its performance. However, the outdoors is beautiful but quite unpredictable. So, when determining the performance of the RV battery, make sure to not overlook the temperature factor.

When you travel from A to B point, you encounter different temperatures. In some places, it might be hot with no wind. While in others, it would be hot, windy, and wet.

So, the last thing you want at this crucial moment is to trip because the temperature is affecting its performance.

It means it is essential to look for weather-friendly batteries that can perform at any temperature without reducing the performance.

Some RV batteries cannot work in freezing and low temperatures, while others cannot perform in hot, humid areas. Make sure to get a battery that can sustain regardless of what the weather is.

4. Price

After determining the power needs of your recreational vehicle, the voltage rating, capacity, and performance of the battery, now you have to consider its price.

High-end batteries might be pricy than your expectations, but consider getting them for a smooth and safe boondocking experience.

It would be a long-term investment that you will enjoy while making your rig better.
