When picking a battery for your RV, there are several things to keep in mind. However, the battery specs aren’t the only things. You should consider your RV as well. You need to think about your electrical consumption, as well as the available space. Can you spare some extra weight, or do you need it for light to pass through?

Big RVs shouldn’t have an issue involving space, but that probably means more electrical consumption as well. Higher consumption does not necessarily mean you need a powerful battery. Instead, you could use several less powerful batteries. Whichever option you choose depends on the electrical power you require, as well as the space available.

You should also keep in mind that some types of batteries require more maintenance than others. Some batteries even produce gas waste and require ventilated storage. On the other hand, some batteries require little to low maintenance. Your budget is also an essential factor, and long-term investment is an option if you often venture into dry camping.

Picking the Right Boondocking Battery

Being out of the grid requires you to be self-sufficient, so batteries need to be reliable. Not just your RV, but everything else inside depends on your batteries for a steady power source. Coming home to a dead battery is not a position you want to find yourself in a while off the grid.

To make a good choice, you need to make sure your battery can handle your power requirements. Most of your electronic equipment should tell you how much power they require. Once you figure out how many amp-hours you need, all that’s left is getting enough batteries to cover it.

However, battery reliability is often in your hands as well, and there are steps you can take to ensure you make the most out of your batteries. For starters, you should try not to overwork your batteries with more than they can handle. Otherwise, you’ll shorten their lifespan.

This can be problematic because batteries often advertise themselves for a certain amount of amp-hours, but you can only use about half of it without shortening its lifespan. If you need a total of 80 amp hours, you’d probably need two batteries to cover that. Two 100 AH batteries with 50% DoD would give you 100AH to work with to cover the 80, AH you need.

You could use a single 100 AH battery, but if its DoD is 50%, your battery may stop working at top efficiency sooner than you’d like. We’ll discuss this further in our buyer’s guide, so keep reading if you want to know more!

Choosing the Right Amp-Hour Amount

The most vital thing to consider when shopping for batteries is the amp hours you need on your RV. Not having enough amp hours may leave you stranded while disconnected from the grid. That’s not a situation you want to find yourself in!

There are a few ways you can go about finding out how many amp-hours you need. Some RVs have screen devices that show your total electrical usage in real-time. Alternatively, most devices tell you how much electricity they use, more often than not in the back. Unfortunately, not all appliances will tell you their amp-hour usage outright, so you’ll need to calculate it yourself.

Fortunately, that’s not difficult to do. A quick browser search should show you how to get it done. Since it’s a simple math formula, all that’s left is to gather the number and calculate it. Once you know how many amp-hours you need, all that’s left is determining which and how many batteries you should get.

It all comes down to the battery’s DoD or depth of discharge. This is the actual flow of electricity you can use from the battery to power everything on your RV. For example, if a 100 AH battery has a DoD of 50%, it means you can safely use 50 AH without damaging the battery. In the same example, if you need 80AH to power your RV, then two of these batteries would be enough.

Another thing to consider is the charge cycle of your battery. If you go dry camping regularly or for extended periods, you’ll find yourself recharging your batteries often. Batteries can only handle so much recharging before their performance begins to fail. If you recharge your batteries frequently, it might be worth investing in a battery with lots of charge cycles.

Frequently Asked Questions (FAQs)

1.     What’s the difference between flooded acid batteries and AGM batteries?

Flooded acid batteries are the least efficient type of battery you can have, and RVs often come equipped with one of these. AGM batteries are the same as flooded lead-acid, but they have features that make them more efficient. For starters, flooded lead-acid batteries are high maintenance. They require ventilation and cleaning since they expel gas and waste.

AGM batteries are sealed, so they expel little to no gas and residue. This improvement alone puts AGM batteries above regular flooded lead-acid ones. However, that’s not all. AGM batteries have a longer lifespan as they have more charge cycles. The best part is that the price isn’t too far from regular batteries, so they’re an affordable upgrade.

2.     Are lithium batteries worth the investment?

In short, yes! Lithium batteries are considerably more potent than flooded lead-acid and even AGM batteries. They leave little to no waste, and they are significantly more powerful. They also have a much longer lifespan; a single lithium battery can outlive several AGM batteries.

They’re also more efficient, as their DoD is higher. AGM and flooded lead-acid batteries have a DoD of 50% or close to it, while lithium batteries range from 90% to 100% DoD. This efficiency means you’ll need fewer batteries to meet the AH quota of your RV, and since they have a long lifespan, you won’t need to replace them regularly. Lithium batteries are less expensive in the long run.

3.     What happens if I use more amp hours than the DoD of my batteries?

Overworking the batteries will result in premature failure. In other words, you shorten the battery’s lifespan. This is why it’s essential to keep track of your energy consumption and make sure you’re not going above the usage of your batteries. Having to replace batteries often is expensive, especially if you’re using lithium batteries!

In the worst case, overworking your batteries may result in a dead battery altogether. So take care of your batteries, and they’ll take care of you when you’re Boondocking.

4.     Can I use 6-volt batteries instead of 12 volts?

Some people prefer 6-volt batteries because they are more reliable, although slightly more expensive. If you prefer using 6-volt batteries, then you’re in luck. With the proper wiring, you can use 6-volt batteries on your RV!

Remember that you need to plug your batteries in parallel for this to work, so you’ll always need two batteries instead of a single one. The benefit of this is that your amps won’t increase, and your batteries will drain equally. Furthermore, your batteries will behave as they were 12 volts this way.

5.     How can I help my batteries last longer?

Not overworking your batteries is just one of the steps you can take to improve their lifespan. You can also recharge your batteries often. If you don’t let them go past 50% of their charge, they’ll last longer. With that said, don’t overcharge your batteries either, as this negatively affects their performance and lifespan.

2.     What steps can I take to reduce my electrical consumption?

Taking steps to prolong your batteries’ life is fine, but you can also take some steps to reduce your overall electrical consumption. Simple changes can make a massive difference in the long run. For example, try switching to LED lighting as they use less energy to run. Solar panels are great if you dry camp often, as you can recharge your batteries essentially for free from anywhere off the grid.

Making a Final Decision on Your Battery

It comes as no surprise that the ideal battery for an RV depends on how you plan to use it. If you’re only going on a quick getaway for a day or two, you don’t need a top-of-the-line battery. You should invest only in what you need. Otherwise, it won’t feel like you’re getting your money’s worth.

On the other hand, if you’re an avid dry camper, it’s well worth investing in the long term. The best kind of batteries for Boondocking is lithium ones. They might seem pricey, but AGM batteries will cost you more in the long run. We’re not just talking about lifespan and power output; there’s a clear weight difference too.

A single lithium battery weighs half as much as an AGM, and you’ll probably need double the amount of AGM batteries even to get close to the power output of lithium batteries. In other words, due to their lightness and efficiency, lithium batteries as basically four times lighters since you also need fewer batteries!

Proper care for your batteries will ensure you don’t need to replace them for a while, so dry campers should note how to best care for their batteries. It’s not a bad idea to carry a spare. You never know what could happen while off the grid. However, hopefully, our tips will help you avoid a situation like that!
