Lead-acid batteries contain electrolytes (weak sulphuric acid), lead, and lead compounds. Normal use of lead-acid batteries as described in the instructions attached to the product does not pose a danger to the users of the batteries. 

A used lead-acid battery is classified as hazardous waste. When transporting batteries, it must be ensured that acid is not spilled into the environment. This is why leaking batteries should be delivered to the collection point in a plastic container or similar.

At the collection points, batteries are generally placed in acid-resistant plastic boxes that are protected from the weather. Scrap batteries sent for recycling must be packaged so that the batteries cannot catch fire. Batteries that have been collected, transported and recycled correctly are not dangerous to the environment or people.
