What Causes Car Battery Corrosion?

It can be quite the surprise to see that powdery substance caked on your battery terminals. What causes car battery corrosion? It’s just a natural result of the constant heating and cooling down that happens with a car battery. This process releases hydrogen gases from the battery.

Those gases mix with surrounding materials and form that powder which attaches itself to the battery terminals. That substance can interfere with the proper operation of your vehicle, which is why it’s important to know how to remove corrosion from a car battery. After all, no one wants to be stranded somewhere in Kyle because of a dead car battery.
