How We Picked


Having an RV battery box is a smart idea. Picking the correct one, though, is another story. There are some considerations that you need to factor in when you are shopping for your battery box. You don’t just settle on what’s there and available. Having enough knowledge about battery boxes can lead you in narrowing down your choices and, ultimately, picking the best one for you and your RV with all your needs and preferences considered.

  • Dimension – you want the size to be proportional to your battery. It should be big and spacious enough to house your battery with some space for air comfortably. Yes, some battery boxes can store batteries of different sizes, but not all are considered universal. When shopping, make sure that you also know the dimensions of your battery. Compare the size of your battery and determine if it will be a good fit. Check to make sure that it can accommodate a Size 24 or work as a group 65 battery box.
  • Durability – this characteristic is essential. You want a battery box that can last you for years. It should be considered as an investment and not just a storage space that you can use for a few months. You should always make every purchase worth the dollar you put into it. The materials used in the RV box should be robust and reliable.
  • Most importantly, the lid should seal tight with four solid supportive walls. It should be able to competently protect your battery from any damages, impact, and bumps. This will not only secure it physically but would help in extending the life of the battery. Not all battery boxes are in the leagues of a Camco heavy-duty double battery box.
  • Weather defense – another factor to think of would be the RV battery box’s capacity to protect your battery from the weather and all the natural elements in the roads and highways. The heat of the sun, rain, mist, fog, and dirt, among others, can damage your RV and the electrical devices that you keep in there. Well secured batteries can provide better performance and consistent power to your electric devices, so they can last longer. Consider the safety features that an RV battery box can offer. If it is 100% water, corrosion, and rust-resistant, you are looking at a potentially good deal.
  • Mounting options – batteries can be cumbersome and bulky. Enclose it in a battery box. It somehow becomes more manageable. You can prevent your battery and the battery box from falling, sliding, or tipping over by mounting it properly. Check the mounting options that come with your future RV battery box. You should be able to quickly secure the box in mounting hardware without too much fuss. Of course, installation should also be user friendly. The simple it is, the better.

Of course, some smart features and portability are also additional aspects that you can investigate. These are just add-ons for you. Most importantly, investigate your budget because this would hugely dictate the direction of your purchase. The price range you have set as your limit will help you further taper down your choices.

Q: How do I secure my RV battery box?

A: Securing your RV battery box is made easier because some boxes come with lids where locks can be placed. Additionally, once securely mounted to your RV, the chance that your battery box and the battery inside it being stolen is very slim. You can add some chains for your peace of mind too.

Thieves are discouraged when the battery box is hard to get to and remove. They want their activities comfortable and clean. Most, if not all, battery boxes would take time and even tools to get to, and time is not something that robbers have in luxury. There are RV lockbox dual battery box types that you can consider when security against theft is critical.

Q: Do RV batteries need to be vented?

A: RV batteries need to be vented. Did you ever wonder why some RVs and campers need to have a water refill at least once or twice? The purpose of the water there is to help tone down the possible overheating. The water becomes water vapor. All batteries should be vented, and you can easily do this even if enclosed in a battery box.

A vented RV battery box can help with battery overheating, prevent battery leaks, and help extend your battery life. Most of the battery boxes have pre-drilled holes in them to serve this purpose.

Q: How to install?

A: Installing and attaching your battery box is the next step in ensuring that the battery’s movement during transit is kept at a minimum. Mounting it is also good, so it can keep the batteries from ramming into one another. There are different ways of attaching the battery box to your RV, and here are some of the ways:

The Bolting Method

  • Determine where you want your battery box to be bolted. You must identify your power source location because it would be good to place your battery box near it. By putting it near the power source, you can have easy access to the battery should you need to check for any issues.
  • By using bolts, you can lock the battery box in place. The bolts will make sure that the battery box won’t shift or move no matter the road’s condition. You can use four 2-inch bolts to secure the box in place.

The Velcro Method

Industrial strength Velcro does make things easier, including the installation of your battery box. All you need when you follow this approach is:

  • Drill a hole inside your RV using power tools.
  • Again, identify the location where the battery box will be placed.
  • Glue the Velcro’s first side on your RV floor. Make sure though that the floor is free from moisture and dirt so you can have maximum adhesion.
  • Cut an opening in your battery box. This is where the Velcro will pass through so it can run on the bottom of your battery enclosure.
  • Once the other side is set, you can already set the battery box on the floor.

Q: How to use it?

A: Using a camper battery box is very simple once it is already installed. After you have mounted your battery box in place and your battery is all snug and comfortable inside, nothing much is required.

You use the battery box to protect your battery, and once it is securely set near the power source, you’re all set. The battery box will do the work on its own. The only time you need to get into it would be to regularly check to ensure that there are no cracks and to occasionally clean it. Other than that, it would be to carry it around should relocation be needed.

You can do this by simply lifting the lid and taking the battery out either for maintenance or replacement. Since most battery boxes are already vented, there’s nothing more to do when you use it. You just make sure that it is installed nicely.

Q: How to maintain & care/ clean?

A: Maintaining and cleaning your RV battery task would already be part of your routine. Doing this is essential, so you can check any damage like cracks or dents that you might not have noticed to have hit it while on the road.

Here are the steps to maintain and give some TLC to your RV’s battery box.

  • Make sure that the battery is disconnected when you start with your regular cleaning. Remember that batteries store electricity, and it may cause you to get electrocuted if you touch it without disconnecting it.
  • Never use a wet cloth to wipe off the dirt and dust build-up. A damp cloth should be enough because again, water and electricity don’t go well together. A wet cloth should be enough to clean the surface of the battery box.
  • Inspect any cracks on your battery box. Water can seep through cracks and, if unattended, may damage your battery. If you find out that there are some cracks, how little it may be, fix it immediately, either using duct tape or epoxy. This will prevent it from getting bigger and causing more damage.

Q: Where to buy?

A: You can purchase your battery box from your local department stores like Lowes and Walmart. The assurance though that all stores carry this item is not guaranteed.
