Which risk increases when a lead-acid battery is over-discharged?

💡 Explanation

Over-discharge leads to the formation of lead sulfate crystals on the plates, which is known as sulfation because the Lead(II) sulfate formed during normal operation is converted to a more stable crystalline form and cannot revert easily: therefore, the active material decreases as sulfation increases, rather than hydrogen generation due to electrolysis at high potentials.
