If a lead-acid battery is stored discharged for more than 30 days, what happens?

Explanation:
When a lead-acid battery stays discharged, the chemical reaction on the plates converts the active materials into lead sulfate. If the battery remains in that discharged state for more than a short period, the lead sulfate can crystallize and harden on the plates. This sulfation reduces the plates’ active surface area and makes it much harder for the battery to accept a recharge, often leading to permanently reduced capacity or shortened life. The practical takeaway is to keep a lead-acid battery charged and recharge it regularly to prevent sulfation. The other outcomes listed aren’t the typical result of storing a discharged battery.
