Microtex 2V OPzV Battery

Microtex 2v OPzV battery manufacturer

For Solar, Electricity Power Generation, Nuclear, Telecommunications, BESS & Standby Power

2v OPzV cells in ABS containers are designed for deep discharge and float long-duration applications in the Solar off-grid backup, Offshore Oil rigs, Telecommunication & Power Generation industries. Our OPzV cells are manufactured using the best industry techniques, extensive testing, and highest quality components. The ABS plastic containers maintain their rigid properties at a wide range of temperatures from −20 to 55 °C (−4 to 131 °F). 

Deep cycle Tubular gel 2v battery have precision German vent valves and no opening for water levels to check. Being a sealed unit, there is no risk of acid spillage. This battery can be installed in a horizontal or vertical position. Recharging is performed much more efficiently due to the special design of the active materials for faster charge acceptance. Gelled electrolyte ensures no stratification of acid & failure due to Partial State of Charge (PSoC)
