Product details
The GBS12/7B.B. battery belongs to the Zelus GBS series, a valve-regulated sealed lead-acid battery using gel electrolyte technology. Its core technology involves mixing sulfuric acid with silica fume to form a gel-like and immobile electrolyte mass. This GEL gel battery design almost completely eliminates the electrolyte evaporation and overflow problems common in traditional flooded batteries, thus avoiding corrosion caused by these issues and significantly enhancing the battery's ability to resist extreme temperatures, shocks, and vibrations. The valve-regulated system ensures that gas generated during use can be safely discharged.Its structure is similar to that of a wet unsealed battery, but the key difference is that calcium is used to replace antimony in the lead plates. This improvement, while retaining excellent mechanical properties, significantly reduces the battery's gas evolution tendency.
The GBS series batteries are available in 6V or 12V integrated form, with a capacity range from 7 to 225 Ah, providing users with flexible options. The batteries support multiple installation methods, both horizontal and vertical, to adapt to different spatial layout requirements. Under normal operating conditions, the series has an expected float charge service life of up to 12 years, or can achieve up to 2500 cycles in deep cycle applications, which meets the definition of a long-life battery under the Eurobat standard.Its deep cycle design is intended to provide maximum capacity and excellent discharge cycle performance.
Specifically, the model GBS12/7 is a 12V battery with a C100 nominal capacity of 7 Ah. The battery is completely filled with gel electrolyte, which not only effectively prevents acid stratification but also allows internal heat to be more evenly conducted to the outer shell, thus ensuring the battery's durable performance and long cycle life in high-temperature environments. The battery is maintenance-free, requiring no water replenishment throughout its service life, and has an extremely low self-discharge rate, with less than 2% capacity loss per month.The special valve it is equipped with has precise on/off pressure control, which is crucial for optimizing the battery's service life in cyclic use.
In terms of physical specifications, the GBS12/7 battery has a length of 151 mm (5.94 inches), a width of 65 mm (2.56 inches), a height of 93 mm (3.66 inches), a total height of 98 mm (3.86 inches). Its weight is approximately 2.45 kg (54.01 pounds). Terminals are available with a standard T2 type option.
With its reliability and environmental adaptability, GBS series batteries are an ideal choice for numerous critical and backup power applications.It is widely used in uninterruptible power supply systems, fire and safety alarm systems, emergency lighting and monitoring systems, telecommunications facilities, and various medical equipment. Additionally, it can provide stable and long-lasting power support in renewable energy systems such as solar and photovoltaic power plants, wind power generation, as well as in scenarios like street lighting, traffic lights, golf carts, and floor cleaning equipment.
