Product details

As B.B. Battery's flagship product, the MSU-300 elevates industrial power reliability to a new dimension. This 2V sealed valve-regulated battery utilizes aerospace-grade anti-corrosion alloy grids combined with patented gel electrolyte technology, maintaining stable output in environments ranging from -20°C to 50°C. Its compact 171mm × 151mm structure supports both horizontal and vertical installation, making it particularly suitable for deployment in space-constrained communication rooms or solar energy storage containers.The built-in absorbent glass mat separator achieves 99% gas recombination efficiency, paired with six independent explosion-proof valves to completely eliminate the risk of electrolyte leakage, meeting fire safety certification standards for high-risk scenarios such as oil platforms and hospital operating rooms. In real-world applications, the MSU-300 demonstrates exceptional environmental adaptability: telecom operator test data shows that the battery can provide continuous power for 14 hours after a base station outage, retaining 85% of its initial capacity even after over 1,200 charge-discharge cycles.Its innovative active material formulation significantly enhances charging efficiency, combined with a 14.09-inch three-dimensional structural design, making this model the preferred solution for data center UPS systems and backup power for intelligent security equipment.
