Product details
For telecommunications facilities and power supply networks requiring stable and reliable backup power, the MSB-500 (2V, 500Ah) battery provides a high-performance solution. This valve-regulated sealed lead-acid battery from B.B. Battery has a nominal voltage of 2V and a nominal capacity of 500Ah at a 10-hour rate, capable of providing long-lasting power support for critical systems. Its sealed structure design completely eliminates the risk of electrolyte leakage or overflow, ensuring a safe and clean operating environment.
The MSB series batteries are specially developed for the power industry and telecommunications applications, with a design focusing on long float life and high capacity.The battery case is made of sturdy opaque impact-resistant ABS plastic. The battery cover is firmly connected to the case, with a well-sealed terminal area. The terminal design varies by type, providing flexibility for users. Six holes on the battery cover are used for electrolyte filling during the production process, and a pressure relief valve made of non-combustible materials installed subsequently further ensures a high level of fire and explosion safety.Both positive and negative plates are coated with a special formulated paste - like active material, which not only enhances excellent charge acceptance. Combined with gel technology electrolyte and absorbent glass fiber separator technology, it achieves efficient gas recombination, thus maximally extending the battery's service life. Under normal operating conditions, the expected service life of MSB series batteries can reach 12 years, meeting Eurobat's definition of long - life batteries.
In addition to telecommunications and power grids, the MSB - 500 battery is also an ideal energy storage choice for renewable energy systems such as solar and wind energy installations. With a wide capacity range from 200 Ah to 3000 Ah, it can meet energy storage needs of different scales.The practicality of this battery is also reflected in its flexible installation method, which allows horizontal or vertical placement, adapting to various space constraints. With compact dimensions (length 241 mm, width 172 mm, height 331 mm) and a weight of approximately 36 kg, it is easy to deploy in data center racks or equipment rooms.
In terms of application scenarios, the MSB - 500 battery performs extremely comprehensively. It can serve as a core component of uninterruptible power supply (UPS) systems, providing uninterrupted power protection for data processing centers and medical equipment. In oil and gas extraction, fire and safety alarm systems, emergency lighting, and video surveillance systems, it provides crucial emergency power supplies.In addition, access control and management systems, rural estates, hotel shops, and even electric vehicle charging infrastructure can rely on its stable output. At a 3-hour rate, its nominal capacity is 375 Ah, and at a 1-hour rate, it is 275 Ah, demonstrating that it can still provide substantial energy at higher discharge rates to meet sudden high-power demands.
The product's advantages stem from its inherent manufacturing processes. The high-tech alloy used for manufacturing the grid ensures extremely high corrosion resistance, and the unique electrolyte fixing system is the cornerstone of long service life. All these are to ensure that users obtain reliable power performance in power networks, industrial control, or safety-critical applications.Whether as a primary power source or a backup power source, the MSB-500 battery, with its reliability and adaptability, has become a solid backbone supporting modern power infrastructure.
