Product details
The GBS12/225B.B. battery is a high-performance product in the Zelus GBS series, which adopts valve-regulated lead-acid (VRLA) technology with gelled electrolyte. By mixing sulfuric acid with silica fume, the electrolyte forms a stable gel state and is completely immobilized. This GEL technology fundamentally solves the common problems of electrolyte evaporation and leakage in traditional flooded batteries, prevents the corrosion caused by these issues, and significantly enhances the battery's tolerance to extreme temperatures, shocks, and vibrations. Its valve regulation system can safely discharge the internal gas generated.Compared with traditional wet batteries (non-sealed), the GBS series replaces antimony with calcium in the lead plates. This design significantly reduces the battery's gas evolution tendency while maintaining excellent mechanical performance.
The battery has a nominal voltage of 12V, a capacity of up to 225Ah (based on C100 discharge rate), and weighs approximately 67.5kg (148.8lbs). Its compact design has dimensions of 522mm in length, 240mm in width, and 216mm in height, with a total height of 219.5mm, offering flexible installation options for horizontal and vertical placement. The battery is equipped with standard B9-type terminals and optional I3-type terminals to meet different connection requirements.
The core advantage of GBS series batteries lies in their deep cycle design, aiming to provide maximum capacity and excellent cycle life. Under normal usage conditions, its expected float charge service life can reach over 12 years, or achieve up to 2500 deep discharge cycles, meeting Eurobat's definition of long-life batteries. The fully filled gel inside the battery not only effectively prevents acid stratification but also optimizes heat conduction, allowing heat to be uniformly transferred to the shell, thus ensuring long-lasting stable performance in high-temperature environments. Additionally, the battery is completely maintenance-free, requiring no daily water replenishment, and has an extremely low self-discharge rate, with monthly capacity loss less than 2%.Its internal special valve is precisely calibrated, with accurate opening and closing pressure distribution, which is crucial for maximizing the battery's cycle life.
With these features, the GBS12/225 battery has become an ideal power solution for many key application areas. It is widely used in uninterruptible power supply (UPS) systems, fire and safety alarm systems, emergency lighting and monitoring systems, as well as various telecommunication facilities and medical equipment. In public infrastructure, it reliably powers street lighting and traffic signals. At the same time, it is also a powerful power source for electric tools such as golf carts and floor cleaning equipment.In the renewable energy field, such as solar power plants and wind power systems, its deep cycle capability and high reliability make it a preferred choice for the energy storage part. The wide capacity range from 7Ah to 225Ah allows the GBS series to flexibly meet diverse power requirements from small security devices to large energy storage sites.
