What is Battery Sulfation?

Sulfation happens inside Lead–acid batteries when the electrolyte starts to break down. As the sulphuric acid (electrolyte) splits up, sulfur ions become free forming crystals. These sulfur ion crystals then stick to the lead plates of the battery, thus forming lead sulfate crystals. With time the crystals grow in size and become hard, covering …
