What Does A Battery Vent Tube Do? Is It Necessary?

When it comes to the important components of a car, batteries are always on the top. They are essential for the functionality of a car. If the battery of your car is not in good condition, then you can’t even start your car. This is why batteries need proper care to stay healthy and perform well. In order to keep your car in good condition, you will need to maintain your car battery.

When batteries are useful for us, they contain hazardous substances that can make us sick. Also, they produce some harmful gases that are very dangerous. This is where the use of battery vent tubes comes in. A vent tube is simply attached to the battery to throw out the hazardous gases from the battery. The main function of a battery vent tube is that it escapes the gases produced in the battery.

So, battery vent tubes are essential to have. Here we will discuss battery vent tubes in detail and determine what battery vent tubes actually do.

What Is Battery Vent?

The battery vent is nothing but the removal of harmful gases from the battery to the outside. Batteries generally have chemicals inside that help in their functions. Sometimes the chemicals inside the battery get melt during the normal functionalities. If this happens, then the battery usually creates gas.

To escape this gas, batteries usually have a hole. This hole is also known as a safety vent. When the pressure of the gases inside the battery increases, the battery vent pops up and expels the gases. This function is essential for the safety and health of the battery. This process is also known as venting.

What Are the Dangers of Not Venting a Battery?

As discussed above, batteries build up gases inside when the chemical melts. When the pressure of these gases increases, they come out from the battery through battery vents. If you don’t vent your battery, then it will be dangerous for you.

If the battery is not vented, then it can cause fire or an explosion in your vehicle. Sometimes these gases could leak from the battery and can make you sick. Although these gases don’t kill you, they can harm your health. This is not worth it, so you should ensure to vent the gases from your battery.

Importance Of Battery Vent Tube

Many people usually don’t understand the purpose of a battery vent tube. But simply, we can say that a vent tube is important for the battery. In the absence of the battery vent tube, the gases will build up in the trunk. These gases are dangerous, and if you breathe in them, then they can harm your health.

If these gases leak from your battery and enter your cabin, then they can create an explosion. It can also cause acid leaking in your battery. Because of the pressurized gases, the battery acid can leak from the battery through the vent. This can result in dissolving the bottom of the battery. This way, the battery can slowly get damaged. This is why having a battery vent tube is important to keep your battery and car safe.

How To Install a Battery Vent Tube?

The gases produced inside batteries are very dangerous and can harm your health. To prevent this, the battery should be appropriately vented. This is a safety measure and shouldn’t be avoided. In general, maintenance-free batteries usually come with two small vents on the side. These ports allow the produced gases inside the battery to escape. Now, let’s understand how to install a vent tube in the battery.

Usually, batteries that need venting come with vent plugs and installation instructions. You can follow these instructions and install the vent tube easily. Here are some steps to help you in this process.

• First, you will need to fix the battery inside your vehicle securely. Tight the hold-down bar properly and ensure that the battery is not shaking.
• If your battery needs venting, then you will need to install the vent plug before connecting the electrical items. If the battery doesn’t need venting, then you can connect the electrical items and start using them.
• If the battery comes with a battery vent tube, then you need to install it on the vent hole.
• Then you can remove the vent plug that is attached to the positive terminal cover. Now, install this vent plug on the opposite vent port of the vent tube.
• After that, you can use the battery by connecting the electronic accessories.

Now, you have successfully installed the vent tube in your battery. This tube will remove the gas from your battery which is very dangerous.

Battery Vent Tube Frequently Asked Questions:

1. Why Do Batteries Vent?

The venting of a battery is not always the case. This is a sign that the battery is failed. This can happen due to over-discharging or a hard short. As a result, the battery can overheat and produce gases inside. These gases are vented outside with the help of a vent tube. In case of battery failure, the battery should be replaced or reconditioned if possible.

2. What Is the Reason for Acid Leak in A Car Battery?

Car batteries can leak acid if the body of the battery is damaged. It can also leak acids if it is overfilled or the cell caps are loosened. Overcharging can also lead a car battery to leak. Another common reason for the battery leaking is too cold weather conditions. If your battery experiences any of these situations, then it can leak.

3. Do I Need to Vent My Battery?

The gases produced inside the battery are not safe and can cause serious health issues. These gases are explosive and can lead to serious hazards if they are not vented. So, the batteries that need venting should have vent tubes to expel these gases to the environment.

4. Is The Smell of Battery Acid Harmful for Health?

If the battery has a leakage, then the battery acid will come out from the battery, and you can smell it. Apart from that, if the battery is overcharged, then it can produce hydrogen sulfide gas. This gas has no color and is flammable and poisonous. This gas can harm human health if inhaled. This gas smells like rotten eggs, which you can easily notice.

5. Where Does the Battery Vent Tube Go?

Vent tubes are usually attached to batteries and go outside the vehicle. They have a vent plug attached to the opposite of the vent hose. A vent tube usually ensures to remove the harmful battery gases outside of the vehicle. Installing vent tubes in the proper way is essential to ensure that the battery gases are removed effectively.

Conclusion

A battery vent tube is an important part of the battery that expels dangerous battery gases. If it is not there, then these gases can harm the health of humans. If you have a battery that needs venting, then you need to know about this.
