How Does Lead-Acid Batteries Work?

Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable.

How to Make Lead Acid Battery Electrolyte Solution

The battery consists of two lead plates, one coated with lead dioxide and the other with pure lead, immersed in an electrolyte solution of sulfuric acid and water. When the battery is charged, a chemical reaction occurs that converts the lead dioxide into lead sulfate and the pure lead into lead sulfate as well.
