b.b.battery GB12/120(12V120AH)

Product details

The Zelus GB12/120B.B.battery redefines industrial-grade energy storage standards, with its core value lying in the perfect integration of gel electrolyte and solid lead coating technology. Unlike traditional liquid batteries, the gel solidification technology ensures zero electrolyte evaporation, completely eliminating the risk of acid leakage, even under severe vibration or 45° tilt conditions. Designed with a 12V voltage, it delivers a 120Ah capacity at 20-hour rate (114Ah at 10-hour rate). Paired with a compact 40kg casing (344×172×280mm), it can be flexibly deployed in space-constrained scenarios such as server room racks and solar energy storage cabinets.The patented layered plate structure endows the battery with exceptional deep-cycle performance, allowing a single discharge depth of up to 80% and tripling the cycle life compared to conventional batteries. The built-in pressure-sensitive safety valve automatically releases gas during overcharging, eliminating the risk of bulging. Combined with a grid alloy formula that replaces antimony with calcium, gas evolution is reduced by 90%, enabling 12 years of maintenance-free operation. Test data shows the battery can still deliver 85% capacity at -40°C, with less than 5% capacity degradation in 65°C high-temperature environments, making it perfectly suited for extreme conditions like polar research stations and desert photovoltaic power plants.As a core power source for fire alarms and medical emergency equipment, the GB12/120B.B.has received Eurobat long-life certification. Its 114Ah/C10 high-rate discharge capability enables instant response to UPS system millisecond-level power switching demands. Weighing 88.18 lbs with I2 terminal design, it serves as an ideal power source for golf carts and cleaning equipment, sustaining daily deep charge-discharge cycles for 6.8 years. Whether handling 7×24-hour loads for telecom base stations or intermittent charging/discharging in solar systems, this battery ensures energy security with a daily self-discharge rate of <0.15%.
