Best RV Battery – Buyer’s Guide

If you like to operate electronics while you’re camping in an RV, you probably know how important it is to have a solid battery. Given all the different styles out there, though, it can be hard to choose the best one for your particular setup. To launch you in the right direction, here are some key points to consider when choosing the best RV battery:

Types of Batteries

When it comes to choosing the best RV battery, it’s important to understand the different types available. After all, your choice of battery can significantly impact your RV’s performance and your overall travel experience. So, to get you off on the right foot, here are some key features that you should be aware of:

1. Lead-Acid Batteries

You’re probably familiar with the trusty old lead-acid batteries – they’ve been the workhorses of the battery world for years, after all. Within this category, there are a couple of subtypes: flooded lead-acid (FLA), sealed lead-acid (SLA), and gel cell batteries.

Flooded Lead-Acid (FLA) Batteries: These are the most traditional type, and probably what you’re going to see the most on the market. People love them because they’re cost-effective and offer reliable performance, but at the same time, they require regular maintenance.

Sealed Lead-Acid (SLA) Batteries: SLA batteries, also known as valve-regulated lead-acid (VRLA) batteries, are maintenance-free. They’re sealed, so you don’t need to worry about checking water levels, like you would in an FLA battery. This convenience comes with a slightly higher price tag, but if you’re not a fan of tinkering with your battery, SLA might be the way to go.

Gel Cell Batteries: These are a subset of SLA batteries that use a gel-like electrolyte. They’re known for their deep cycling capabilities and durability, retaining the maintenance-free trait you’d find in SLA batteries. At the same time, they can handle high temperatures better than traditional SLA batteries, though they’re also more sensitive to overcharging.

2. Lithium-Ion Batteries

LiFePO4: You’ll hear me mention LiFePO4 batteries throughout the article, but what does it mean? Well, the name is a shorthand version for describing what the battery is made from. It uses lithium (Li), iron (Fe), and phosphate (PO) as the cathode material to create a highly resilient, reversible electricity storage system. Reversible electricy meaning that it can be both charged and discharged.

Lithium-ion batteries are all the rage in the RV world, thanks to their high energy density and impressive longevity. They’re lighter, smaller, and pack more punch compared to lead-acid batteries, but the benefits don’t end there. They also offer a deeper depth of discharge, which means you can use more of their capacity without harming the battery’s overall life.

Still, you should know that these cutting-edge benefits come with a heftier price tag. Lithium-ion batteries are more expensive upfront, but if you’re all about long-term efficiency, quick charging, and saving space in your RV, they might be worth the investment. As they say, you truly do get what you pay for.

3. Absorbent Glass Mat (AGM) Batteries:

AGM batteries fall somewhere between traditional lead-acid batteries and lithium-ion ones. They offer the maintenance-free advantages of SLA batteries and some of the performance benefits of lithium-ion batteries, though they also tend to be quite expensive. Even so, they’re a great compromise if you want improved performance without the ultra-premium cost of lithium-ion batteries.

Important Features

Rechargeability

The rechargeability of an RV battery is an important factor to consider. Even beyond how quickly and easily a battery regains a charge, you have to consider how much juice that same battery will lose while idling over time. Here are a couple more specific points to consider:

Recharge Efficiency. How much energy can they take in during charging, and how much can they retain? These are important questions to ask when choosing the best RV battery. Lithium-ion batteries usually take the crown here due to their high charge acceptance and low self-discharge rate, meaning they won’t lose their charge as quickly when you’re not using them.

Solar Power Compatibility. In recent years, I’ve found that many RV enthusiasts are turning to solar power as a sustainable and independent way to keep their batteries charged. So, if you’re planning to harness the power of the sun, make sure your chosen RV battery plays well with solar systems. Lithium-ion batteries, again, tend to shine here due to their ability to handle irregular charging patterns (pun intended).

Power Output

When you’re cruising along in your RV, you want to have the right amount of power to keep your lights on, gadgets charged, and appliances humming. So, let’s break down some key factors that will help you understand power output in RV batteries.

Amp-Hour (Ah) Rating
Think of the amp-hour (Ah) rating as the size of your RV battery’s fuel tank. This rating tells you how much energy the battery can deliver over a specific period of time: the higher the Ah rating, the longer your battery can sustain your power needs without needing a recharge. This is especially critical during those remote camping trips when access to electricity might be limited.

Voltage
Voltage, on the other hand, is like the electrical pressure pushing energy through your RV’s systems. Most RV setups run on 12-volt systems, so a single 12-volt battery will be sufficient for you – in fact, all of the products in this review are 12-volt. But if you need more power, you can wire multiple batteries in series to get 24 or 48 volts, effectively boosting your energy capacity.

Discharge Rate
Discharge rate, measured in C-ratings, tells you how quickly your battery can deliver its stored energy. A higher C-rating means it can handle higher energy demands for shorter bursts. For RVs, where power needs often vary, having a battery with a decent C-rating ensures you won’t run out of juice when you need it most.

Depth of Discharge (DoD)
Depth of Discharge (DoD) tells you how much stored power you can use before needing a recharge. Some batteries can handle deeper dives – say 80% DoD – without damaging their longevity, while others prefer to stay closer to the shallows. Opting for a battery with a higher DoD can give you more options and versatility while you’re out and about.

Inverter Compatibility
An inverter transforms the direct current (DC) from your battery into alternating current (AC) that powers most of your appliances. It’s important to make sure that your RV battery’s power output matches the requirements of your inverter. An incompatible pairing might result in energy wastage or even damage to your appliances.

In a nutshell, when hunting for the best RV battery, don’t just settle for a one-size-fits-all solution. Consider your power habits, the duration of your trips, and the types of devices you’ll be running. A battery with the right amp-hour rating, suitable voltage, discharge rate, DoD, and inverter compatibility can keep your RV charged up and ready for anything.

Maintenance and Storage

Proper care of your RV battery is essential to ensure its longevity and optimal performance throughout your travels. After all, you want your adventures to be powered smoothly, right? Here are a few tips to keep your battery purring like new for many years to come:

1. Inspect It Regularly

Just like your vehicle needs regular check-ups, your RV battery also requires periodic inspections. Specifically, you’ll want to look out for any signs of corrosion on the terminals and cables. If you spot any, you can use a mixture of baking soda and water to gently scrub the corrosion away.

2. Maintain a Charging Routine

We mentioned it before, but your RV battery really isn’t a fan of being discharged completely. Try to maintain a routine where you don’t let the battery drain too much before recharging it – for example, lithium-ion batteries prefer to be kept at around a 50% charge while being stored. Lead-acid batteries should be fully charged before storage to prevent sulfation.

3. Beware of Temperature

Extreme temperatures can play havoc with your battery’s health. If you’re storing your RV for an extended period, it’s best to remove the battery and keep it in a cool, dry place. If you’re on the road during harsh weather, it’s a good idea to make sure your battery is adequately protected from freezing or scorching temperatures.

4. Remove for Long-Term Storage

When you’re done with your RV adventures for the season, I’d recommend removing the battery and storing it in a climate-controlled environment. This can significantly extend its life by preventing self-discharge and other chemical reactions that occur in extreme temperatures.
