Product Profile

MICROTEX OPzS cells belong to the most enduring lead acid batteries. They are suitable for stand - by operations as well as for capacitive loads. They perfectly meet requirements for bridging times between 1h and more than 10h.

MICROTEX Stationary OPzS Cells are used in Telecommunication Sectors, for Emergency Lighting and Microwave Radio Systems and also in Power Generating Plants.
