How Much Sulfuric Acid is in a Lead Acid Battery? A lead acid battery contains approximately 98% sulfuric acid and 2% water. The concentration of sulfuric acid in a lead acid battery is typically between 30 and 40%. Why Dilute Sulphuric Acid is Used in Car Batteries? Car batteries are one of the most important parts of a car.
the lead–acid battery model in electric or hybrid vehicles, the charging and discharging process is of great importance, i.e., a charging/discharging voltage and state of charge (SoC) [7]. Very often the model of the lead–acid battery for the Stop-Start Technology is a circuit model with two resistance–capacitance (RC) blocks [8].
Studying the water loss in lead acid batteries, as described in ref. [10], is a notable research focus because the loss of water over time reduces the Coulombic efficiency of lead-acid batteries, affects the redox reactions of the electrode materials, and even leads to thermal runaway [7, 11, 12].

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.
