By combining the newly developed tubular positive plates with fumed gelled electrolyte, CSBattery created the innovative OPzV range of batteries. The OPzV series is designed and manufactured according to DIN standards, with die-casted positive grid and patented active material formula, they exceed the DIN standard values. They offer 20-25 years design life in float service at 25°C and are more suitable for cyclic use under extreme operating conditions. This range is recommended for telecom outdoor applications, renewable energy systems, photovoltaic / wind energy storage and UPS and other harsh environment applications.
