Reasons for Corrosion on Battery Terminals of your Audi

Reasons for Corrosion on Battery Terminals of Your Audi

Corrosion is the reaction of hydrogen gas, which is released from the acid and the other particles present in the air.

There are 2 possibilities that the corrosion occurs on which terminal-

If the corrosion occurs on the negative terminal, then it shows that the battery is undercharged.

If the battery is overcharged, then the corrosion will occur on the positive terminal.

The battery of your Audi is very important for efficient performance.

There are many reasons for corrosion on the battery terminals of your Audi.

Overcharging of battery

Battery should be charged properly and until a certain limit.

By increasing the volume, there is also an increase in the pressure of the electrolyte.

Increase in the pressure of the electrolyte will cause the leakage of the electrolyte through vents.

Formation of hydrogen gas

The reactions in the battery produce hydrogen gas.

Hydrogen gas is harmful when it leaks and produces corrosion on the terminals of the battery.

The corrosion can occur either on the positive terminal or on the negative terminals.

Leakage of electrolyte

In the cases of old batteries & lack of maintenance, the electrolyte leaks and produces corrosion on the terminals.

If you are using maintenance-free batteries then there is less chance of electrolyte leakage.

The batteries which require water constantly have more chance of corrosion on the terminals.

Overfilling of battery

The electrolyte or water should be filled in the battery up to the specified marked limit.

If the water is filled extra, then there is a chance of leaking, & it will affect the terminals of the battery.

Overfilling is also an important cause of corrosion & to avoid it, seek the service of an Audi specialist.

Always note the age of your battery

If your battery is 5 years old or more, then there is more chance of finding corrosion on the terminals of the battery.

You can simply avoid such a case by replacing the battery on time and avoid engine problems in your Audi.
