How Lead-Acid Batteries Work
The electrolyte in a lead-acid battery is sulfuric acid, which acts as a conductor for the flow of electrons between the lead plates. When the battery is charged, the sulfuric acid reacts with the lead plates to form lead sulfate and water. When the battery is discharged, the lead sulfate and water react to form sulfuric acid and lead.

What Is Battery Acid? Sulfuric Acid Facts
How does a facility report batteries for Tier II? | US EPA
The facility must evaluate if sulfuric acid should be reported on the Tier II form by aggregating the amount of sulfuric acid in each battery and determine if the total quantity meets the threshold level. The threshold level for EHSs established in 40 CFR part 370 is 500 lbs or the threshold planning quantity (TPQ), whichever is lower.
