Ventilated tube plate batteries for renewable energy applications.

RES OPzS is a premium battery range, developed for applications requiring regular deep cycles. It is an energy-saving solution for energy storage with a lower cost per cycle, high reliability and excellent performance. Also for remote installations, where long discharges take place and the best charging properties are essential.

The optimal design, the exclusive use of high-quality materials, the robust construction and the advanced production processes make RES OPzS batteries the ideal solution for demanding applications for renewable energy storage.

RES OPzV brings you the same benefits as a RES OPzS battery, but they are also Valve Regulated GEL batteries. In other words maintenance-friendly batteries with a minimum of maintenance.
