Buying Guide

Although purchasing a battery box for your RV seems like a simple thing and you may feel like there’s no need to go over a buying guide for something as straightforward as a battery box. But there is a lot that can get in your way if the battery box you chose is not aligned with your rig requirements.

So, here’s a buying guide for you to avoid any trouble after the purchase!

  • Size of the battery box

First, you need to know the exact size of your batteries and get a box that will accommodate them. Try to choose a box that is the right fit for your rig, meaning it should not be too compact that the battery can barely fit into it, neither should it be too large that the battery can dangle around the box.

Some models have space for multiple batteries and adjustable dividers that help fit the batteries in their place. Compatibility between the battery and the size of the box is a crucial factor. Therefore, you should always double-check the specs of the box before making the final call.

  • Weather Protection And Safety

Another important factor to note is the safety feature of the box, which is also the primary reason we get a box for the battery. No matter if your battery box is installed inside or outside the RV, you need to make sure that it is safe and would protect against weather conditions as well as road bumps.

If installed outside, then it must have the resilience to withstand severe weather conditions. Some models come with a UV defense feature, which protects your battery against the UV rays and does not let your battery’s efficiency be decreased.

Similarly, apart from waterproof battery boxes, some markets feature lid-vent, and drainage holes keep the water out during heavy rains.

Other than weatherproofing, make sure that the box you are getting is reliable in securing the batteries in their place and offer a locking mechanism that will keep the battery from falling off on a bumpy road.

  • User-friendly Features

Mounting the battery box in an RV could be difficult if the box you have does not have convenient features like sturdy handles or straps for picking up the whole thing. 

Therefore, it is crucial to choose a battery box that offers you a great grip while lifting it, so you do not accidentally drop the battery while trying to secure it in its designated place.

  • Battery Box with Smart Features

If you want to enjoy the optimal comfort of a battery box, we would suggest you go for a battery box with smart features. These models allow you to have USB ports for charging your gadgets off the grid, LED light panel, and 12-volt outlets.

Although these boxes are a bit pricey as compared to regular battery boxes but are worth the money with all these features.

These 12V outlets will come in handy for charging your phones and running other appliances. At the same time, the LED battery charges will tell you the residual battery percentage by pressing the buttons. So, these functions will provide you the value for your money in one way or the other.

  • Durability

Durability is the one thing you always look for when buying any big or small product. So while looking for a battery box, you should always ensure if its construction is up to the standard. Since a battery box has to carry the load of the battery, it should be sturdy to last for years.

Plus, it has to be durable enough to withstand any weather conditions, heavy blows from the bumpy roads, and an efficient locking mechanism to protect the battery against thieves.


  • Why is a battery box needed in an RV?

There are multiple reasons to have a battery box, especially in your RV. The first is that it holds your battery in its place instead of tossing it around and bumping it with other objects. A battery box ensures that the battery does not get damaged during bumpy rides or twisted turns.

Another reason for having a battery box is to protect the battery against thieves; most battery boxes come with locking mechanisms that are hard or nearly impossible to break. Hence, it saves your expensive battery from getting stolen while you are out there in the woods.

  • Why should I choose an expensive battery box over a cheap one?

It is not always about the price. While buying a battery box, you should go for the quality of its construction. Many of the cheap battery boxes are poorly made and will do you no good in performance.

Therefore, the extra bucks you spend on a good quality battery box will prove to be worth your money in the long run. It will protect your battery from getting damaged in case of road accidents. If some robbers break into your car, they will not be able to get their hands on the battery.

So, protecting your battery should be your first preference because if it gets damaged or stolen while you are on the road, you will have a really hard time starting your vehicle and charging your appliances.

  • Do I need to install a fan for my RV battery box?

No, there is no need to install any additional fan for your RV battery box because most battery boxes have vents that allow the battery to cool down by air ventilation. However, if you set up your battery box inside the RV and travel to hot climates, you can opt for a vented cooling system. 

The vented cooling system vents the air from outside and prevents the battery from getting overheated.

  • Can I charge my RV battery in a battery box?

Yes, you can charge your RV battery in a battery box. To charge the battery while it is fixed inside a box, all you need to ensure is that the box is not too compact for the battery. If that is the case, then there is a higher risk of your battery getting overheated, resulting in some fire hazard.

Hence, to avoid any such incident, make sure that the box you are getting for your battery is compatible with the size of the battery.

  • Can I put my lead-acid battery in a battery box?

Yes, there is no harm in putting your lead-acid battery in a battery box as long as the box has proper sealing and ventilation chambers for the air to pass.


Proper sealing will ensure that your battery is fixed in a place and will not wiggle around with the movement of the vehicle. Because if your battery is not properly fastened to its place, it can get damaged by constant motion while you are on the road. The ventilation chambers will prevent the battery from getting overheated, especially if you have it set up inside the RV.

  • Can I put two batteries in one battery box?

If the battery box you have is designed for multiple batteries or has enough room for two or more batteries, then you can put two batteries in one box. However, we would not suggest putting multiple batteries in a box that is manufactured for a single battery because that can cause damage to the batteries.

If you want to have one box for multiple batteries, our recommendation is to opt for the boxes that are specifically designed for that purpose. Those battery boxes also come with an adjustable divider that ensures safe distance and proper fitting of each battery.


The batteries that power up your RVs and many other big and small appliances have to be protected like the most treasured object, and if this one thing breaks down, you’re gonna have a real hard time trying to fix it on the road. Thus, instead of taking them for granted, you should spend extra few bucks to ensure their safety.

The battery box will secure your battery from elements that are inevitable, such as water, extreme weather temperatures, road bumps as well as looters. So, protect your valuable battery and find yourself a perfect battery box from our list of recommendations!
