Why do my Car Battery Terminals keep Corroding?

The problem with battery corrosion is that it can eat away at your Battery Cables and other components under your hood. Corrosion is kind of like cancer. While we cannot get rid of it completely, we can keep it at bay. How does corrosion happen? Well there is acid inside the battery. The battery is plastic, but coming out of the battery are metal posts that we hook the cables to. Where those posts seal to the battery we often have a little bit of leakage where vapors come up and cause the corrosion. The best ways to clean the battery is tons of water. The second thing we can do is disconnect the cables individually and wire brush the terminals on both sides. Then just keep maintaining it!
