A lead acid battery has lead plates immersed in electrolyte liquid, typically sulfuric acid. This combination creates an electro-chemical reaction that For example, electric vehicles typically favor lithium-ion batteries for this reason. 8. Environmental Concerns with Lead Toxicity: The presence of lead in these batteries raises
The hydrogen reacts with the lead sulfate to form sulfuric acid and lead, and when most of the sulfate is gone, hydrogen rises from the negative plates. The oxygen in the water reacts with the lead sulfate on the positive plates to turn them once again into lead dioxide, and oxygen bubbles rise from the positive plates when the reaction is almost complete.

A lead-acid battery in not an ideal battery, so some (slow) internal discharge takes place, which is why these batteries drain slowly without an external load, just sitting on the shelf. What causes the reaction to proceed is the electrical potential difference between the reactants in their initial (unreacted) state and their final (fully reacted ) state.
The acidity in a battery is caused by the presence of sulfuric acid, which is derived from the chemical reaction between sulfur dioxide and water. However, lead also
