Proven energy suppliers for sensitive systems

OPzV batteries are sealed batteries in which the electrolyte is gel-bound. The high-performance tubular plate technology ensures a long service life and high cycle stability. They are ideally suited for use e.g. in hazard alarm technology, safety lighting, telecommunications and railway technology. The batteries of the OPzV series are cost-saving and particularly economical due to their high performance. They are maintenance-free and therefore no refilling of water is necessary.

The battery is fully recyclable.

System features
