FAQS about Battery chemical material classification standards

Why are batteries classified as hazardous materials?

Batteries are classified as hazardous materials because they contain toxic substances like mercury, lead, cadmium, and lithium. Their classification varies based on chemical composition and toxicity, with common categories including lithium-ion and lead-acid batteries.
