The power station on these battery boxes include a woven hold-down strap and foot clamps for keeping your battery secured once it is inside. The best budget solution doesn’t mean that you need to lose out on functionality, and that certainly is the case with Camco. battery boxes are great for travelling, but what we don’t like are the accompanying chores, like having to clean the best car floor mats.

Battery Box FAQs

What does a battery box do?

A battery box allows you to easily transport or store a battery without the worry of acid leaks. Additionally, some batteries may give off gases when running or charging; a battery box will help to regulate exposure to such fumes.

What are battery boxes made of?

Most battery boxes are made from a form of plastic such as polypropylene or polyethylene; they are typically constructed of a solid base unit and a detachable lid. Combined, the base unit and lid form a box that can help prevent acid spillage and other potential issues.

What is a BCI group size?

Batteries are assigned a BCI group size; this will allow you to match your battery to the perfectly sized battery box. Before purchasing a battery box, check your battery’s BCI group size, which should be indicated on the label.

Do you need to vent a battery box?

Venting a battery box is not necessary, but still recommended. A battery box with a vent allows for hydrogen gases to escape - a byproduct of the battery being utilized.

How do you use a battery box?

For most battery boxes, open the lid and place the battery in the box. Once laid in the box, replace the lid and secure it for safety. Smart battery boxes may include terminal connections on the inside of the box that allow you to route power externally; in this case, consult the user manual for detailed instructions. Batteries especially used with boxes can be quite cumbersome, so make sure you have one that has a battery case with mounting hardware to secure it, and prevent it from sliding or falling, especially on small boats.

How do you vent a battery box?

If the battery box you purchased doesn’t include a vent, you can make holes in the plastic lid by using a household drill and the correct bit. Be careful when adding vent holes to a smart battery box as you want to avoid hitting any added electrical components.
