Why Storing Your Batteries In A Battery Box Is Important

Keeping your battery away from extreme weather conditions is very important because it lengthens its lifespan and keeps your battery operating at its maximum output.

A battery box also ensures that if your battery does start leaking for whatever reason, the battery acid won’t endanger those around it. Battery acid is also very corrosive and could damage whatever is underneath the battery.

Another reason to use a battery box is for aesthetic reasons. Having all your wires neatly attached to your battery inside a battery box makes your entire power setup look clean and professional.

Picking The Right Battery Box For Your RV or Camper

Depending on your power needs, you might have to get one or several batteries. The most common battery requirements in modern RVs are 12-volt and 6-volt batteries. Having a battery box for each of the various sizes will ensure that your batteries are stored safely and easy to access when you need to disconnect the batteries for storage or maintenance.

Battery Box Features That Matter

Not all battery boxes are created equally. However, there are some key features that you should be looking out for when deciding between different battery boxes.

Battery Capacity

Is one battery enough to power your camping setup? Do you require multiple batteries to get the job done? When choosing a battery box, you need to assess the maximum power consumption your batteries will be under and select a box with the space to house enough batteries to meet that demand.

Cable Access

You need to ensure that your battery box has well-designed cable access and management built-in. The last thing you want to worry about after buying a battery box is drilling holes and compromising the box’s seal to get your cables to where they need to go.

UV Protection

Having a battery box built using UV-resistant materials will ensure the box’s longevity when exposed to direct sunlight. The longer your battery box can stay out in the sun, the fewer boxes you’ll have to buy in the long term.

Material Resistances

Sunlight isn’t the only thing that damages battery boxes. A hot day, a cold night or multiple rain showers can all degrade your battery box’s materials. Choosing a suitable material will ensure that your batteries stay cool and dry, no matter the weather.

Ventilation

If you decide to store your batteries inside your RV cabin, it is crucial to have a box with proper ventilation and a hose that you can mount to ensure that any dangerous fumes get safely vented to the outdoors.

Conclusion

We chose the NOCO HM318BKS Group 24-31 Snap-Top Battery Box because it is the most versatile battery box out of all the options available for batteries in this size group. We recommend you consider the size and placement of your batteries before purchasing any of the products we listed above.

Be sure to check that your batteries will survive wherever adventure takes you.

Good luck, and happy camping!
