Classic OPzS batteries have been proven energy suppliers for decades, which  convince in robustness, reliability and extremely long design- or cycle life. OPzS is a  flooded Lead Acid battery that adopts Tubular Plate technology to offer high reliability  and performance. OPzS is designed and manufactured according to DIN40736- 2/IEC60896-11 standards and with die-casting positive spine and patent formula of  active material. OPzS series batteries offer 400% more cyclic life than the standby  series. It is suitable for solar and wind renewable energy storage, traction etc. OPzS  series is the best choice for energy system in high altitude area.
