Sealed batteries VLRA

The electrolyte is fixed in a gel.

Excellent storage properties

Combined with high reliability.

Larger energy supply

Deep discharge safety.


OPzV batteries are sealed batteries in which the electrolyte is gel-like. The high-performance tubular plate technology ensures a long service life and high cycle stability. They are ideal for applications such as hazard detection technology, safety lighting, telecommunications and railroad technology. The batteries in the OPzV series are cost-saving and particularly economical thanks to their performance. They are maintenance-free and therefore do not require topping up with water.
