Audi Battery Terminal Corrosion: Causes And Solutions in Powell
Like other parts of the Audi, the battery terminal is corroded with a lead-acid battery.
When the battery temperature changed, the gases are produced from the battery through vents.
If these gases mix with other elements, then it will cause corrosion around the battery.
In an Audi, the corrosion generally occurs in two terminals such as: • Undercharged battery will corrode the negative terminal • The overcharged battery will corrode the positive terminal
The below points define the common causes of battery terminal corrosion in Audi.
Leakage of electrolyte
Ignoring the battery service or not replacing the old one will cause electrolyte leakage.
Electrolyte leaking is accumulated around the battery terminal and leads to battery corrosion.
Production of hydrogen gas
When the leaked hydrogen gases react with other gases, it will cause terminal corrosion.
In these cases, the corrosion can either occur on the positive or negative terminal.
Overfilled batteries
When the water is filled in the battery, it needs to be filled up till the markers.
If the water is filled beyond its marked level, then you will notice the issues like: • Water is leaking from the
vents • Affects the terminals
• Lead to battery corrosion
Chemical reactions in the copper clamps
Copper clamps are used in the car for connecting the battery to the cables.
When the battery pressure increased, the copper reacts with the leaked sulphuric acid and causes corrosion.
Overcharged battery
If the battery of your Audi is overcharged, then it will cause issues like: • Increase the temperature of the battery • Make the electrolyte expand
in volume.
Therefore, corrosion formed on the terminals and decreases the battery efficiency.
Age of the battery
Aged battery is the most common cause behind the corrosion on battery terminals.
Using the same battery for up to 5 years is producing corrosion on the terminals.
Solution for corrosion
If you are staying away from the home, use soda water to remove the corrosion.
People living in Powell can consult with a reputed mechanic to replace the battery terminals.
