If you own an RV, you know that having a battery box is an important RV accessory. It is important to protect the battery from the elements and a standard battery box will do that. If you don't have one, you run the risk of damaging your battery.

These containers are roughly the size of a small toolbox, but rather than hold jumper cables, spare RV parts like stainless steel hardware, or small portable battery chargers, you place the battery of vehicle in it.

It may seem like a simple purchase, but there are different options available, as well as a few things you need to consider when purchasing one for a camper. We've taken a look at various models of an RV battery box to come up with our top 4 picks.

FAQs For Buying RV Battery Box

To help with your decision making, we've answered a few of the more popular questions that come up time and time again when looking for the best RV battery box.

What is an RV Battery Box?

It is a lightweight case made of damage-resistant polypropylene designed to house the RV battery as it is resting on a battery tray to help prevent shaking, and the case protects it from the elements. This might include water, gas, oil, and even acid, all the things that you find inside an engine.

All of the substances pose a threat to the life of your battery, so anything that will help prevent damage is worth the investment. It's a good idea to get one unless you want to put important parts of your vehicle in jeopardy. 

Do I Need to Lock My Battery Box?

It's certainly recommended. For starters, it will mean that the battery is secure and won't be falling out or rattling around too much. Many are snap-top battery boxes, and they come with straps and even locks to make sure they don't come open.

Others also recommend locking it to something more sturdy so that it can't get stolen. A strap can also work well with this or figuring out a way to drill it to the floor.
