One of the most important things to have at the heart of your RV is a good RV battery system. Your RV battery system will not only start the vehicle, but the house battery bank is what supplies all your electricity so you can use things like your TV, charge your phone, plug in your laptop, and so on.
The more efficient each RV battery in the system is, the longer it’ll hold on to a charge, and the less time you’ll need to be connected to a trickle charge to top it up at each spot.
There are two types of batteries when it comes to RVs. Cranking batteries to start the engine, and deep cycle batteries that supply electricity for a prolonged period of time and are used in your house bank.

The Renogy Deep Cycle AGM RV Battery is one of the best RV batteries around when it comes to holding a charge and minimal maintenance.
It’s a fully sealed AGM RV battery that is resistant to shock, vibrations can be mounted anywhere, and is virtually maintenance-free.
The AGM RV battery has an exceptionally low discharge rate when not in use, meaning you won’t have to worry about topping it up all the time while your RV is parked at home.
With 100 amp hours, this RV battery has more than enough voltage for powering your fridge, TV, and anything else you have in your RV. And if you were to run 4 of them in your house bank, you’d have all the power you need for days at a time.
This RV battery recharges well and is designed to be super-efficient when charged with an RV solar panel, so you can be off-grid for as long as you please.
Another great thing about this RV battery is that it works in low temperatures down to 0 celsius, so if you enjoy some winter RV-ing, it’s a great one to go for.
The only downside is that it’s heavy at 63lbs, so moving it around will be hard work.
The WindyNation RV Battery is another fully sealed AGM lead-acid battery that’s perfect for use in your RV.
This battery comes with 100 amp hours and is made using 99.995% pure virgin lead. The purity of the lead means the battery has an extremely low and long-lasting discharge rate, which is perfect for using appliances off-grid, like in your RV.
The battery is sealed for safety, handles shock and vibrations well, and you can pretty much mount it anywhere you like. It is heavy though at 66lbs, so don’t put it anywhere that’s hard to access, or may hurt your back moving it.
This RV battery charges well and it’s designed for use with solar panels, so if you have some on your RV, you can go for weeks at a time without having to hook up to a trickle.
The RV battery has a floating life of 10-12 years, so if you buy 4 of them for your house bank and look after them, you shouldn’t need a replacement any time soon.
The Universal Power Group Solar Winds RV Battery is about as good as it gets when it comes to amp-hours delivering 100 Ah at 12 volts, so 1200 volts total.
By having a few of these RV batteries in your house bank, you’ll be able to go for days at a time without needing to plug in and recharge.
When a recharge is needed, they top up pretty quickly, and being a solar wind battery, they are perfect for use with your RV solar panels if you have any.
This RV battery is a fully sealed deep-cycle lead-acid battery. It’s made tough to handle any collisions and vibrations, plus there are zero risks of any leaks.
Overall they have a pretty good life span of 3-5 years, and when considering their lowish price, are excellent value too. The only thing holding this battery back is its weight.
At 64lb, this RV battery is heavy, so when installation it be careful not to pull your back out. And make sure you install it in a place where you can leave it, as you don’t want to be carrying it around often.
The Optima OPT8016-103 RV Battery is quite special as it’s designed as both a cranking battery and deep cycle battery, all in one.
This means you can use it to start your RV or have it in your house battery bank.
This RV battery holds its charge well and will provide 55 amp hours consistently for 20 hours, meaning you can run your RV electronics with ease, especially if you have a few of them.
The RV battery charges up quickly, and it comes with a 120-minute reserve to help you make it to the next trickle charge point in times of need.
They are perfect batteries to connect to solar panels on your RV and are super safe too. You can mount them in virtually any position without worry and they’re super durable with fifteen times more vibration resistance than your normal RV battery.
It’s not the toughest battery around when it comes to collisions though, so be sure to put it somewhere where it’s not going to move around.
Although this RV battery is awesome when used consistently, you’re going to need to look after it a lot when you’re not using it.
If the charge drops too low, these batteries will lose their ability to hold a charge well and need hooking up to a trickle charge to ensure they don’t get too low.
The ODYSSEY PC680 RV Battery is a deep cycle lead-acid battery that is perfect for adding to the house bank of your RV.
The RV battery is fully sealed, meaning no lead-acid leaks, and it’s built to handle impact, vibrations, plus it can be mounted in virtually any position.

This RV battery comes with a 2-year warranty and is designed t have a 3-10 year service life. Most people use it for 5-8 years before having to replace it, which is pretty good going.
The amp hours on this RV battery are a little low though at just 20 when compared to others that have 50 or 100.
There is also no reserve built into this Rv battery and it comes without the terminals shown in the picture, so you’ll need to order those separately.
Overall, this RV battery looks good on paper but when comes down to it, there are better batteries out there to choose from.
The VMAXTANKS VMAX V35-857 RV Battery is about as light and compact as a battery for your RV can get. This makes installing the battery and moving around, about as easy as it can get.
The battery comes with a non-spillable design for safety purposes, and it’s full shock and vibration resistant. You can mount this battery pretty much anywhere, and feel safe knowing it’ll be fine no matter what happens.
The battery charges up super fast, in less than 3 hours, and requires very little maintenance. You can drain it fully and still bring it back to life, and it’ll hold a charge well.
This battery does have low amp hours with just 35, and it’s not the best battery for your RV house bank when used alone. You’d want at least 4 x 100 ah batteries in your house bank.
But, it’s not a bad choice to add one of these to your house bank for use as a portable power supply that you can take into the outdoors when needed, or use on its own in the RV for specific low voltage tasks.
Overall, this is not the RV battery you want holding up the charge in your house bank but it could be a useful add-on.
The Odyssey PC925 RV Battery is a crank battery, not a deep cycle battery. So it’s not the battery to use for building your house bank with, but it’s a good one to add to it as a reserve for your engine and when you want a battery that’s portable.
This RV battery is a sealed AGM lead-acid battery. It’s quite light, easy to move around, and can be mounted in any position.
It has a cold crank amp rating of 330 which will easily start your RV and has a 28 amp hour rating for topping up your house bank. It also works in extreme conditions and will start your RV when it’s 0 Fahrenheit outside.
It charges exceptionally fast and will be full within 4-6 hours, and it has an excellent life span of up to 10 years, with a 4-year warranty to boot.
Overall this is a great RV battery for use as a spare caring battery that can also top off your house bank supply.
The Optima Batteries 8052-161 D31M RV Battery is a great choice if you’re looking for a cranking and deep cycle battery in one.
This RV battery holds 900 cold-cranking amps and will start your RV with ease. Plus, it has 75 amp-hours of deep cycle charge for your RV appliances.
The battery has a reserve of 155 mins and a long and slow discharge, but it’s not the battery you want to build your house bank from, as you don’t need all of them to be able to crank.
This RV battery is best suited as an add-on to top up your house bank and start your RV.
It’s a durable battery with a long 5-10 year life span when looked after, but it is heavy at 60 lbs and you’ll need to look after it.
This type of battery requires constant topping up as if it gets too low on charge, it’ll struggle to hold a charge again. This means that when it’s not in use, you’ll need to top it up quite often.
There are two types of RV batteries; cranking for starting the engine and a deep cycle for running the appliances. You’re going to need both in your RV, and you can choose to buy one that does both too.
It’s best to have at least 4 house batteries and 1 cranking battery plus a spare so you’re always covered. You can link the spare cranking battery into your house bank for efficiency if you go for a multipurpose deep cycle crank battery all in one, which is recommended.
For your house batteries, you’re going to want to use an RV battery with a minimum of 75 amp hours, and ideally, 100 amp hours to build your house bank with.
A 100 amp-hour battery is best because it has enough capacity to run things like fridges, TVs, and other appliances for a greater length of time. And when used in parallel with 3 others, you’ll be able to be off gird without a charge for days at a time.
When picking an RV battery you should check its weight and dimensions are going to fit in the spot you have laid out for it. A 100 amp hour RV battery is usually around 60 lbs which is heavy to move around. Make sure your house bank is in an easily accessible area so you can move your batteries in without much work.
Every RV battery in the review is sealed and designed to manage both shock and vibrations well. It’s key that you pick a battery with the above features not only for safety but for the life span of the battery.
A well-sealed and protected battery can last up to 10 years without needing a replacement, especially if it’s treated well.
Think about how you’re going to charge your batteries most often. Are you going to plug them into a trickle or use solar the most? Some batteries are designed with solar panels in mind and will work far more efficiently than ones that don’t.
We highly recommend using solar panels as they allow you to be off-grid with no need for a trickle connection for much longer periods, letting you take your RV on some serious adventures.
The all-around best RV battery is the Renogy Deep Cycle AGM RV Battery. This RV battery has 100 amp hours that it discharges slowly to run all your RV appliances, recharges well with solar, and is super long=lasting. With 4 of these in your house bank and a good solar system, you can be off-gird for weeks at a time.
The best RV battery, if you’re on a budget, is the Universal Power Group Solar Winds RV Battery. This RV battery is about as inexpensive as a 100 amp hour battery can be while still providing an excellent amount of power for your RV. It’s durable, lasts for years, and recharges well via trickle or solar.
The best RV battery in the review is the WindyNation RV Battery. This battery is made to be maintenance-free and has the lowest discharge rate around. This means you won’t have to top it off very often when it’s not in use, and when in use it provides an ample 100 amp hours for your RV house bank. It’s also one of the longest-lasting RV batteries with a life of up to 12 years.
