As stated earlier, under normal circumstances, the battery will never lose sulfuric acid but will only lose water. That means the levels of sulfuric acid either free or in the plates remain the same. When you add more acid to the battery, it means the level of sulfuric acid concentration will increase dramatically with every drop added.

A lead-acid battery consists of lead plates, lead oxide, and a sulfuric acid and water solution called electrolyte. The plates are placed in the electrolyte, and when a chemical reaction is initiated, a current flows from the lead oxide to the lead plates. This creates an electrical charge that can be used to power various devices.

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.
