Product details

The valve-regulated sealed lead-acid batteries of the Zelus GBS series use gelled electrolyte technology, whose core is a mixture of sulfuric acid and fumed silica that forms a fixed, non-flowing gel. This design almost completely eliminates the electrolyte evaporation and overflow common to traditional flooded batteries, and it gives the battery greater tolerance of extreme temperatures together with excellent resistance to impact and vibration. The valve-regulated system safely vents gas generated inside the battery. Calcium replaces the antimony in the lead plates, which significantly reduces gassing tendency while preserving good mechanical properties. GBS series batteries are offered with overall voltages of 6 volts or 12 volts and a wide capacity range from 7 Ah to 225 Ah, meeting varied energy storage needs. Installation supports horizontal or vertical placement, which helps with space utilization. Under normal working conditions the design service life reaches 12 years and cycle life is outstanding with up to 2500 deep cycles, and according to the Eurobat standard the series belongs to the long-life battery category. The series is an ideal power supply for uninterruptible power supply systems, 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. Its deep-cycle design is intended to provide maximum capacity and optimal discharge cycle performance. The advantages of GBS batteries come from the solid lead plating technology and the gelled electrolyte they use, which together ensure long-term stable operation. Service life and capacity performance are excellent: under standard conditions the service life exceeds 12 years, the capacity range is broad, and the battery supports up to 2500 cycles of use. Capacity values such as C2, C5, C8, C10, C20 and C100 vary with the specific series, so the appropriate rating should be selected for each duty. In solar and photovoltaic applications in particular, GBS batteries show distinctive characteristics. They offer an exceptionally long cycle life and maintain lasting, stable performance at high temperatures. The interior is completely filled with gel, so heat generated inside conducts easily to the case, which benefits thermal management. Gelling the electrolyte effectively prevents acid stratification, a key factor in maintaining long-term battery performance. The battery is completely maintenance free and needs no water replenishment throughout its service life. Its self-discharge rate is extremely low, with capacity loss of less than 2% per month, which makes it well suited to occasions requiring long-term energy storage. The special valve provides precise control of opening and closing pressure, which is important for optimizing internal pressure and extending battery (especially cycle) life. Specifically, GBS6-215 is a 6 volt battery with a nominal capacity of 215 Ah at the 8-hour rate, a weight of about 32.8 kg, a standard terminal type of I3 and an optional I4 terminal.
