What happens when a battery smells like rotten eggs?

As we know, these batteries are filled with an electrolyte of water and sulfuric acid. When you smell that rotten egg odor, the battery is heating up so much that the sulfuric acid (H₂SO₄) is being converted into a gas called Hydrogen Sulfide (H₂S). This does not happen when a battery is working properly.

Why does my car battery stink?
