The lead battery, the most common in the market because of its properties, has a composition that allows the recycling and reuse of more than 97% of its compounds. The contained lead means about 56% of the total weight of the battery and once discarded could be recycled to obtain the following products:

  • Lead compounds. They are about 80% of the total weight of the battery and they are separated in three common forms (lead pastes, metallic lead and terminals) whose majority composition is lead (more than 65%) and water and other materials such as antimony. These compounds are metallurgically treated to obtain secondary lead.

  • Polypropylene. About 5% of the battery. The polypropylene is sent to treatment and recycling plants and it is usually reused by the same Automobile Industry.

  • Electrolyte. About 12% of the weight of the battery. The electrolyte is water with dissolved sulphuric acid in a proportion of about 20%. A part of the electrolyte is reused in the process of recycling and the rest is sent to treatment and valuation plants.

  • Separators. They are about 3% of the total weight. There are different kinds of separators and they are usually made out of plastic materials. Nowadays it is the only part of the battery that has no valuation.
