The OPzV series is designed with a gel electrolyte and a tubular positive plate. It also has the advantages of a valve-regulated battery (maintenance-free) and an open-cell battery (floating charge / cycle life). It is particularly suitable for use with a backup time of 1 to 20 hours. Because it is not limited by the use environment or maintenance conditions, the OPzV series is suitable for environments with large temperature differences and unstable grids, or renewable energy storage systems that have been in an electrical state for a long time.
