Product details
In various power demand scenarios, a reliable and long-lasting backup power source is crucial. As a representative model of the Zelus GBS series, the GBS12/33 B.B. battery, with its advanced gel electrolyte (VRLA) technology, provides excellent performance and adaptability. The series of batteries form a stationary gel-like electrolyte by mixing sulfuric acid with silica fume, fundamentally avoiding common issues such as electrolyte evaporation, overflow, and resulting corrosion problems in traditional flooded batteries.This gel - based design not only stabilizes the battery structure but also enhances its environmental tolerance, effectively resisting the effects of extreme temperatures, impacts, and vibrations.
GBS12/33 is a 12V battery with a nominal capacity of 33 Ah (based on the C10 standard) and a weight of approximately 11.3 kg. With its compact size design—length 195 mm, width 129 mm, height 168 mm (total height 178.6 mm)—it can be flexibly installed in space - constrained environments and supports multiple installation methods, both horizontal and vertical, which greatly facilitates system integration. The battery terminal is of standard type B7, providing convenience for connection.
The core advantage of this battery lies in its deep - cycle capability and long service life. It is developed using solid lead - coating technology to provide maximum capacity and depth of discharge. Under normal operating conditions, it has a design life of up to 12 years or can achieve up to 2500 charge - discharge cycles, which meets Eurobat's definition of a long - life battery. The fully filled gel electrolyte inside not only effectively prevents acid stratification but also promotes uniform heat conduction to the shell, ensuring long - lasting and stable performance even in high - temperature environments.In addition, the special valve adjustment system equipped with the battery, by precisely controlling the opening and closing pressures of gases, plays a crucial role in extending cycle life.
For users, the GBS12/33 is a fully maintenance-free power solution that requires no water replenishment throughout its entire service life. Its self-discharge rate is extremely low, with monthly capacity loss less than 2%, which means it can maintain sufficient power even when in standby for a long time, ready to be used at any time.
Therefore, the GBS12/33 B.B. battery is an ideal choice for numerous key application areas. It is particularly suitable for renewable energy systems such as solar photovoltaic power stations and wind power generation, providing reliable support for energy storage.Meanwhile, in communication base stations, medical equipment, fire and safety alarm systems, emergency lighting, and monitoring systems, it can ensure uninterrupted operation of core equipment. In addition, in public transportation fields such as road lighting, traffic lights, as well as electric vehicles like golf carts and floor cleaning equipment, it also performs exceptionally well, providing stable and long-lasting power.
