Why do RV battery boxes need to be vented?

Air should be able to circulate inside your RV battery box to avoid overheating. It will also help prevent leaks. We all know the dangers of overheating and battery leaks. They can cause fire and battery explosions. They can hurt you and damage your battery and other stuff it comes in contact with.

This is also why it’s important for you to check your battery’s electrolyte and water levels. You leave your vent caps on while charging your battery to prevent loss of water.

Water will help prevent overheating but since water becomes vapor, it is important that there are vents where they can pass through. The holes in your vented RV battery box will help keep you safe and extend the life of your battery.

Gas is emitted when your battery is overcharged especially if you’re using a lead acid type of battery. Some fumes can still get out even if your battery is sealed. A battery box gives you an additional layer of protection.

How to install my RV battery box?

You should install your RV battery box properly so that it will stay put and movement will be limited especially during transit. There are different ways to attach your RV battery box to your rig but these are the most common methods.

The Bolting Method

You bolt your RV battery box near your power source. The bolts will ensure that your RV battery box is in place and won’t move no matter how rough the terrain gets. RV owners usually use 2inch bolts on the 4 sides of the battery box to secure it in place.

The Velcro Method

Using an industrial strength Velcro makes attaching your battery box to your RV so much easier. But first you need to drill a hole where you want to put the box in your camper. Then make sure that the surface is free from any dirt and moisture so that the Velcro will stick to it properly.

Next, you have to cut a hole in your RV battery box. This is where the Velcro will pass through to reach the bottom side of your battery housing. Once both sides are set, you can already place the battery box on the floor.

However, take note that the Velcro method should only be a temporary way of installing your battery box because it will eventually wear out and won’t be able to keep your battery box securely in its place.

How do I secure my RV battery box?

Some RV battery boxes already come with their own fastening system for easy and convenient installation. There are cables that you can use to secure your RV battery box. Some lids come with locks so that you can secure your battery inside. You can also use chains if you like.

With these strategies to secure your battery, thieves will have a hard time to get and remove your RV batteries.

How can I maintain and clean my RV battery box?

It is important to maintain and clean your RV battery box. By doing so, you can check for any dents and damages that it might have incurred during travel.

Here’s how you can do this:

  1. Make sure that your RV battery is disconnected when you conduct your maintenance routine. This is to prevent injuries and electrocution.
  2. Use a damp cloth to wipe off any dust and dirt on the surfaces of your RV battery and battery box. Do not use water because it doesn’t go well with electricity.
  3. Check your RV battery box thoroughly. Look for any cracks or damages. If there are cracks, make sure you fix them right away with the use of epoxy or duct tape. Take note that water and other elements can make their way through those cracks and could damage your RV battery.
  4. If the damage is irreparable, it’s time to get a new battery box rather than risk damaging your RV battery.

You can also check the manual of your battery box for other instructions regarding its proper maintenance.
