Product details
The GBS12/120B.B. battery, as a representative model of the Zelus GBS series, is a valve - regulated sealed lead - acid (VRLA) battery using gel electrolyte technology. Its core technology lies in mixing sulfuric acid with silica ash to form a fixed gel - like electrolyte. This design fundamentally solves the common problems of electrolyte evaporation, overflow and subsequent corrosion in traditional flooded batteries, while endowing the battery with excellent environmental adaptability and physical stability.
This battery has strong resistance to extreme temperatures, shocks and vibrations, and its performance far exceeds that of ordinary wet batteries.Its valve regulation system can safely discharge the gas generated inside, ensuring safe use. In structure, it uses calcium to replace antimony in the lead plates. This improvement, while maintaining excellent mechanical properties, significantly reduces the battery's gas evolution tendency, making the battery more stable and durable.
GBS12/120 is a 12 - volt battery with a nominal capacity of 120Ah (based on C100 discharge rate). The specific capacity value varies with different discharge rates (such as C2, C5, C8, C10, C20), which reflects its design as a deep - cycle battery, aiming to provide maximum capacity output and excellent discharge cycle performance. The battery weighs approximately 39 kilograms (8.98 lbs), with a compact external dimension design, the length is 407 mm (16.02 inches), width is 173 mm (6.81 inches), height is 210 mm (8.27 inches), and total height is 239 mm (9.41 inches). It uses standard I2-type terminals, and an important installation advantage is that it can be flexibly installed in horizontal or vertical positions, providing convenience for system integration.
The core feature of this battery lies in its long service life and high reliability. Under normal working conditions, its expected service life can reach more than 12 years, with a cycle life of up to 2500 cycles, which meets Eurobat's definition of a long-life battery.This is attributed to its fully filled internal gel electrolyte, which not only effectively prevents acid stratification but also promotes uniform heat conduction to the battery case, thus ensuring the battery's long-lasting performance in high-temperature environments. In addition, the battery is completely maintenance-free, requiring no regular water replenishment, and has an extremely low self-discharge rate, with a monthly capacity loss of less than 2%, making it very suitable for scenarios requiring long-term standby or intermittent use.
The precisely controlled special valve system is crucial for its cycle life, ensuring that the internal pressure is in an optimally distributed state. These characteristics make the GBS12/120B.B. battery an ideal power source for various key application scenarios.It is widely used in uninterruptible power supply (UPS), fire and safety alarm systems, emergency lighting and monitoring systems, telecommunications facilities, and various medical equipment. Additionally, it can provide stable and reliable power support in street lighting, traffic lights, golf carts, floor cleaning equipment, and in the renewable energy field such as the energy storage part of solar and wind power generation systems.
