If your car battery terminals are corroded, it can be difficult to start your car. Corroded battery terminals can also cause your car to run poorly. In this article, we will show you how to troubleshoot corroded battery terminals. We will also show you how to prevent corrosion from happening in the first place.
So, what cause car battery terminal corrosion?
The most common cause of car battery terminal corrosion is exposure to the elements, specifically moisture and oxygen. Over time, these elements can cause the terminals to corrode and eventually fail.
Let’s dig into it and see what we can uncover.
Why Do Car Batteries Get Corrosion On The Terminals?
When a car battery is charging, the hydrogen gas that is produced can mix with other things in the air and cause corrosion on the terminals. This is because the hydrogen gas is being released from the acid in the battery. The acid reacts with the other substances in the air and creates the corrosion. This can happen over time or if the battery is not properly maintained.
As well as that, Corrosion is the process of deterioration of a material, usually a metal, by chemical or electrochemical reaction with its environment. In a car battery, corrosion happens when hydrogen gas is released from the acid inside the battery. This acid mixes with other substances in the air under the hood of the car, causing the corrosion that you can see.

How To Fix Battery Terminal Corrosion?
If your car battery terminals are looking a little green and fuzzy, it’s probably time to clean them. But before you reach for the nearest can of WD-40, there are a few things you should know.
Corroded battery terminals are a common problem, and one that’s relatively easy to fix. The greenish-white substance you see is actually lead sulfate, and it’s a by-product of the chemical reaction that takes place when your battery discharges and recharges.
Over time, the lead sulfate builds up on the terminals and can eventually prevent the battery from being able to hold a charge. In some cases, the corrosion can even cause a short circuit.
Cleaning battery terminals is a pretty straightforward process, but there are a few things you need to know before you get started. First, it’s important to use the right tools. A wire brush will do the trick, but make sure it’s a good quality brush that won’t shed any bristles into the battery.
Second, you’ll need to be careful not to damage the battery terminals. The lead sulfate is corrosive, so you don’t want to use anything that’s too abrasive.
Finally, it’s always a good idea to wear gloves and eye protection when you’re working with batteries. The acid in the battery can be harmful if it comes into contact with your skin or eyes.
Now that you know what you need, here’s how to clean battery terminals:
1. Begin by disconnecting the negative terminal from the battery. This is usually the black one.
2. Use the wire brush to remove as much of the corrosion from the terminal as possible.
3. Once the terminals are clean, you can reconnect them to the battery.
4. To prevent the corrosion from coming back, it’s a good idea to apply a thin layer of Vaseline or other petroleum jelly to the terminals. This will create a barrier that will prevent the lead sulfate from building up again.
If your battery terminals are badly corroded, you may need to replace the terminals. You can buy new terminals at most auto parts stores.
Follow these steps and you’ll have clean battery terminals in no time.
