Factors to Consider when Selecting your Boondocking RV Battery

Boondocking RV Battery

Not all of us have the technical aptitude to pick out the best RV battery for boondocking, however, there are a few basic functions and capacities that you can easily familiarize yourself with.

What Is The Voltage?

There are two main types of voltage that you’ll find in most RV batteries:

  • 6 Volt – these types of batteries tend to last a lot longer than their 12-volt cousins and are generally not expensive. This makes it the perfect choice for boondockers who want something they can rely on over a few days. You can rig up a few 6-volt batteries to gain more voltage.
  • 12-volt – These kinds are batteries are not as durable as 6-volters, mainly because they don’t hold a charge for as long. They are generally more powerful and less expensive than 6-volt batteries. However, they also have less discharge and recharge cycles than 6-volts.

What Types Of Batteries Do You Need?

There are different types of batteries, each one bringing something unique to your RV experience:

  • Lead-acid batteries – these types of batteries have a lead plate or grid lining that is coated in a liquid electrolyte. They are generally cheap to buy, resilient and can be overcharged without burning out. They are a heavier model of battery.
  • Absorbed Glass Mat (AGM) batteries – these are sealed lead-acid batteries, developed in the 70s and very popular amongst dry-campers. They can charge much faster than any other and because the cells inside are sealed, they don’t release harmful gasses or liquids during charging or use.
  • Gel batteries – this style of battery is manufactured in viscous gel electrolyte, which is safer than lead-acid. These batteries also do not give off any gases during charge as they are fully sealed. They are very low maintenance and tolerant of high temperatures.
  • Lithium-ion batteries – these batteries are said to be the safest for boondocking as they are stable and long-lasting. They feature high energy density and lose little charge at low temperatures.

What Is The Capacity Of Your Battery?

The battery’s capacity is usually measured in amp-hours (Ah) over a certain period. This indicates how much electricity a battery can deliver over the space of an hour. So when you are picking up your next battery, it will be worth looking at this and mapping it against the period over which you’re going to be camping.

You’ll also need to factor in what tools and appliances you have onboard your RV and how much you’ll be using them. Add together all the appliances and utilities you’ll be planning on using during your RV trip to figure out the level of Ah you’ll be needing.

Your appliances should only really consume around 50% to 60% of your total battery life. If you use any more than this then it could lead to deep discharges that will affect your battery’s ability to function in the long run.

Frequently Asked Questions

What Is The Ideal Battery For A Full-Time Boondocker?

A full-time boondocker is someone you can regard as being on the road 24/7, so your power needs will be a lot more elaborate than someone who does it once or twice a month.

If you are full-time, you’ll probably need to hook up your battery to a solar power unit that is compatible. This means that you can charge your battery on those bright sunny days and conserve it for those overcast days.

Because you’ll be needing more power over a longer period, we recommend purchasing a lithium-ion battery for its charge and resilience.

What Is The Best Battery For Part-Time Boondockers?

People who dry-camp on a more casual basis – once or twice a month – won’t require a super-powerful battery, but they might need something that has little self-discharge over a few months. This will be especially important if you plan on keeping it in storage over an extended period.

You’ll probably be wanting an AGM battery, as it will give you everything you need to power your RV for a few days. These types of batteries are also much cheaper than their lithium-ion counterparts.
