Batteries are made from 99.99% pure lead

CYCLON batteries from Enersys are made from 99.99% pure lead, while the plates are extremely thin, so they provide more surface area than conventional batteries and far more power. High purity acid is absorbed right into the Absorbed Glass Mat (AGM) plate separators, so the battery provides leak-proof operation in any position. Product’s outer jacket delivers extreme shock, vibration, temperature and flammability protection. Product has high cycle life, long float life, low self discharge, flexible mounting orientation, high charge acceptance, high stable voltage delivery and power density. http://www.xtronics.ca
