Technical Specification for Stationary VRLA Cells (DIN 40742) |
 |
Application |
The Power Safe OPzV range are valve regulated lead-acid cells which use a proven combination of GEL and tubular technologies to offer a very high level of reliability.
These single cells benet from an optimized plate design which gives capacities in excess of the DIN standard values.
In addition, the Power Safe OPzV range offers both a long float life and a high cycle life for a truly flexible solution.
