Product details
The GBS12-85 belongs to the Zelus GBS Series, which consists of valve-regulated lead-acid (VRLA) batteries using gelled electrolyte. Its core technology lies in mixing sulfuric acid with fumed silica to form an immobile gel-like substance as the electrolyte, fundamentally solving the electrolyte evaporation, spillage, and resulting corrosion problems common to conventional flooded batteries, while giving the battery greater resistance to extreme temperatures and excellent shock and vibration resistance. The series uses a valve regulation system that can safely vent internally generated gas when necessary; structurally it is similar to a non-sealed wet battery, but the antimony in the lead plates is replaced by calcium, which significantly reduces the battery's gassing tendency while maintaining good mechanical properties.
GBS Series batteries are offered in overall voltage ratings of 6 volts or 12 volts, with capacities ranging from 7 Ah to 225 Ah, and support horizontal or vertical installation. Under normal operating conditions, GBS Series batteries have an expected service life of up to 12 years; their deep-cycle design provides a cycle life of up to 2,500 cycles, meeting the Eurobat standard for long-life batteries. The GBS12-85 has a nominal voltage of 12 volts, a nominal capacity of 85 Ah at a specific discharge rate, a weight of approximately 29.5 kg (65.04 lb), and a compact dimensional design that facilitates integration into various equipment.
The battery's core advantage lies in the combination of solid lead coating technology and gelled electrolyte, ensuring maximum capacity and deep discharge capability: the gel completely fills the battery's internal space, helping heat conduct evenly to the case and enhancing durable performance in high-temperature environments; electrolyte gelation effectively prevents acid stratification and ensures stable performance; the battery is completely Maintenance Free and requires no periodic water replenishment; its self-discharge rate is extremely low, with capacity loss of less than 2% per month, making it suitable for long standby or intermittent use. In addition, the special valve provides precise opening and closing pressure control, which is critical to optimizing internal gas management and extending battery cycle life.
Thanks to its reliability and durability, GBS Series batteries are suitable for uninterruptible power supplies (UPS), fire and security alarm systems, emergency lighting and monitoring systems, telecommunications facilities, and various medical equipment, and are also widely used in street lighting, traffic signals, golf carts, floor cleaning equipment, and other fields. In renewable energy fields such as solar photovoltaic plants and wind power systems, their long cycle life, high-temperature resistance, and Maintenance Free advantages are fully realized, providing stable and lasting power support for communications equipment backup or off-grid solar energy storage.
