Can Sulfation Be Reversed in a Lead-Acid Battery?
Sulfation can be removed from a lead-acid battery by applying an overcharge to a fully charged battery using a regulated current of around 200mA for a period of roughly 24 hours. This process can be repeated if necessary, but it is important to monitor the battery closely during the process to prevent overheating or damage.

Lead-acid batteries are widely used in various applications, including vehicles, backup power systems, and renewable energy storage. They are known for their relatively low cost and high surge current levels, making them a …
What is a Lead-Acid Battery? Construction, Operation, and …
Lead-acid batteries should never be allowed to remain for a long period in a discharged state because lead sulfate could harden and permanently clog the pores of the electrodes. Before storing it for a long time the battery should be completely charged, then the electrolyte should be drained so that the battery is stored dry.
