b.b.battery MSB-400(2V,400Ah)(2V400AH)

Product details

B.B.Battery MSB-400 (2V 400Ah) valve controlled sealed battery redefines industrial grade power guarantee standards with technological innovation. As a star product in the MSB series, its 2V individual voltage is 400Ah@C10 Capacity design, can stably output 4800Wh of electricity in a 10 hour discharge scenario, and maintain 300Ah efficiency even after a 3-hour discharge, perfectly adapting to the networking requirements of 48V systems in telecommunications core rooms. The impact resistant ABS shell is paired with B6 standard terminals, achieving IP65 protection level in a lightweight design of 69.4 pounds (31.5kg). The unique pressure relief valve uses non combustible materials, ensuring fire safety even in extreme environments. The electrode plate adopts rare earth alloy casting technology, combined with a special paste formula, to achieve a cycle life of over 4000 times and maintain a charging efficiency of over 95% in a wide temperature range of -20 ℃ to 50 ℃. The patented electrolyte fixation system locks the active substance through an absorbent glass fiber partition, eliminating the risk of thermal runaway. The measured gas composite efficiency is over 98%. The product has passed the Eurobat long-life certification, with a 12 year float life significantly reducing operation and maintenance costs. It has been successfully applied to 192V energy storage systems in Spanish photovoltaic power plants, Singapore data centers, and Middle Eastern oil drilling platforms. The compact 8.31 × 6.92 × 12.95 inch (211 × 176 × 329mm) enclosure supports rack stacking and can flexibly adapt to space limited scenarios such as computer rooms and base stations. The standard I3 industrial terminal is optional to meet the high current transmission requirements, and the 357mm thickness design ensures the ventilation efficiency of the battery pack. As the preferred backup power source for hospital ICU and highway monitoring system, MSB-400 has been deployed globally with over 200000 units and a failure rate of less than 0.3%, reinterpreting the reliability boundary of industrial batteries.
