Energy Systems (ES) Lead Acid battery

SECTION 2: Hazards identification

No hazards occur during the normal operation of a Lead Acid Battery as it is described in the instructions for use that are provided with the Battery. However, Lead-Acid Batteries have three significant characteristics:  They contain an electrolyte which contains diluted sulphuric acid. Sulphuric acid may cause severe chemical burns.  During the charging process or during operation they might develop hydrogen gas and oxygen, which under certain circumstances may result in an explosive mixture.  They can contain a considerable amount of energy, which may be a source of high electrical current and a severe electrical shock in the event of a short circuit. The Batteries may have to be marked with the symbols listed under section 15. 3. Composition and Information on the main Ingredients CAS no.

Lead Monoxide (CAS No.: 1317-36-8) is listed as a substance of very high concern under EU REACH Regulation. Once the batteries / cells are filled with electrolyte all Lead Monoxide is transformed and the presence of any SVHC has ended.
