Product details
The GBS12/75B.B. battery belongs to the Zelus GBS series. It is a valve - regulated lead - acid (VRLA) battery using gel electrolyte technology. Its core lies in mixing sulfuric acid with silica fume to form a gel - like and immobile electrolyte mass. This GEL technology almost completely eliminates the common electrolyte evaporation and overflow phenomena in traditional flooded batteries, thus avoiding the resulting corrosion problems. Meanwhile, gel batteries exhibit superior performance, including stronger resistance to extreme temperatures, shocks, and vibrations. Its valve adjustment system allows safe gas discharge, ensuring safe use.Structurally, it is similar to wet batteries, but replaces antimony in the lead plates with calcium, which retains excellent mechanical properties while significantly reducing the gas evolution tendency.
GBS series batteries are available in 6V or 12V configurations, with a wide range of capacities from 7Ah to 225Ah, providing flexible options for different needs. The GBS12/75 model is a 12V battery with a nominal capacity of 75Ah at a 100 - hour rate. It has flexible installation methods, supporting horizontal and vertical installation to accommodate various space constraints.Under normal working conditions, the designed service life of this series of batteries can be as long as 12 years, or it can provide a deep cycle life of up to 2500 cycles, which falls into the category of long service life according to the Eurobat standard. Its capacity varies according to different discharge rates (such as C2, C5, C8, C10, C20, C100) to meet diverse discharge requirements.
This battery adopts solid lead coating technology and gel electrolyte, and is a deep cycle lead-acid battery designed to provide maximum capacity and excellent discharge cycle performance.The gel completely fills the internal space of the battery, allowing heat to be easily conducted to the shell, thus ensuring long-lasting performance in high-temperature environments. The gelation of the electrolyte also effectively prevents acid stratification, enhancing the stability and consistency of the battery. As a maintenance-free battery, it does not require regular water replenishment, significantly reducing maintenance work. Its self-discharge rate is extremely low, with a monthly capacity loss of less than 2%, making it suitable for long-term storage or standby use. In addition, the design of special valves ensures precise distribution of opening and closing pressures, which is crucial for extending the battery's cycle life.
The physical dimensions of the GBS 12/75 battery are length 259.5 mm (10.22 inches), width 172.6 mm (6.8 inches), height 200.5 mm (7.89 inches), total height 217 mm (8.54 inches), weight approximately 24 kg (52.91 lbs). It is equipped with standard I2-type terminals, with a compact and sturdy structure.
With these technical parameters and functional details, the GBS series batteries are an ideal power solution for numerous key application fields. It is highly suitable for renewable energy systems such as solar power plants and wind power generation, providing stable energy storage for off-grid or grid-connected systems.In communication equipment, uninterruptible power supplies (UPS), fire and safety alarm systems, emergency lighting and monitoring systems, and medical equipment, it can ensure the continuous power supply for key equipment. Additionally, in public infrastructure fields such as traffic lights and road lighting, as well as mobile applications such as golf carts and floor cleaning equipment, GBS batteries can provide reliable and long-lasting power support to meet the needs of various harsh usage scenarios.
