Car batteries are essential components of any vehicle, providing the power necessary to start the engine and power the car's electrical systems. However, many people may not realize just how much lead is contained in a car battery. In this article, we will explore the amount of lead in an average car battery, the purity of the lead, and how to safely remove and dispose of it. Whether you're a car enthusiast or simply curious about the inner workings of your vehicle, read on to learn more about car battery lead.
How much lead may a lead-acid car battery contain?
The U.S. EPA says lead-acid batteries may contain up to 18 pounds of lead. That is a qualified upper amount, not an average or a measurement for every car battery; the amount varies by battery. EPA also notes that lead-acid batteries contain corrosive, lead-contaminated sulfuric acid. Follow the label and return a used battery to a retailer or local household hazardous-waste program.

How do you remove lead from a car battery?
Do not open or dismantle a used car battery to recover lead. OSHA identifies battery plates, lead scrap and oxide as sources of lead exposure during repair or reclaim work. Keep the battery intact, follow its handling warnings, and return it to a battery retailer or local household-hazardous-waste program. Do not put it in household trash or municipal recycling.

Can you melt car battery lead?
Do not melt lead recovered from a car battery at home. OSHA warns that heating lead can create lead fumes, and the EPA directs consumers to return lead-acid batteries to a battery retailer or local household-hazardous-waste program. Use that collection route instead of opening, heating or processing the battery yourself.
