Product details
The GBS12-75 belongs to the Zelus GBS Series and uses valve-regulated lead-acid (VRLA) technology, with the core being gelled electrolyte: sulfuric acid is mixed with fumed silica to form a stable, immobile gel-like substance, almost completely avoiding the electrolyte evaporation and overflow common in traditional flooded batteries, thereby effectively preventing the corrosion problems caused by these phenomena. Gel batteries demonstrate superior performance, including greater resistance to extreme temperatures and excellent shock and vibration resistance; their valve regulation system can safely vent gases generated inside the battery. Structurally, it is similar to a non-sealed wet battery, but the key difference is the replacement of antimony in the lead plates with calcium; this change greatly reduces the battery's gassing tendency while retaining good mechanical properties.
This series of batteries is available in 6 V or 12 V monobloc forms, with capacities ranging from 7 Ah to 225 Ah, and installation supports both horizontal and vertical positions. Under normal operating conditions, the expected float service life of GBS Series batteries can reach 12 years; in cyclic charge-discharge applications, the cycle life is up to 2500 cycles, which falls within the long-life category according to the Eurobat standard. Their nominal capacity is based on different discharge rates, such as C2, C5, C10, C20, C100, etc., with specific values varying by series. Taking the GBS12-75 model as an example, its nominal capacity at the 100-hour rate is 75 Ah.
GBS Series batteries are an ideal power choice for uninterruptible power supplies (UPS), fire and security alarm systems, emergency lighting and monitoring systems, telecommunications facilities, medical equipment, street lighting and traffic signals, golf carts, floor cleaning equipment, and renewable energy systems such as solar and wind power. They are particularly suitable for solar and photovoltaic applications, where their long cycle life and lasting stable performance in high-temperature environments stand out. The gel electrolyte completely fills the internal space of the battery, allowing heat to be conducted uniformly and efficiently to the case, which aids temperature management; gelation of the electrolyte also effectively prevents acid stratification, improving battery reliability. As a Maintenance Free battery, it requires no water replenishment throughout its service life, greatly reducing maintenance costs and workload; the self-discharge rate is extremely low, with capacity loss of less than 2% per month, making it very suitable for occasions requiring long-term standby power or intermittent use. The precise opening and closing pressure distribution of the special valve inside the battery is critical to optimizing battery cycle life.
Specifically for the GBS12-75 model, its voltage is 12 V. In terms of physical dimensions, the length (L) is 259.5 mm (approx. 10.22 inches), the width (W) is 172.6 mm (approx. 6.8 inches), the height (H) is 200.5 mm (approx. 7.89 inches), and the total height (TH) is 217 mm (approx. 8.54 inches). The battery weight is approximately 24 kg (52.91 lbs), and the terminal type is standard I2. This deep-cycle lead-acid battery is developed using solid lead coating technology combined with gel electrolyte, designed to provide maximum capacity and discharge cycle life to meet the power needs of various demanding application scenarios.
