Product details
In the field of power security and energy storage, B.B. Battery's MSB-400 (2V, 400Ah) Valve-Regulated Sealed Lead-Acid Battery, with its excellent reliability and wide applicability, has become the preferred power solution for numerous key applications. This battery belongs to the MSB series, which is specifically designed to meet the high-standard requirements of power grids, the power industry, and telecommunication systems. The series has a nominal voltage of 2V and capacities ranging from 200Ah to 3000Ah. The MSB-400 model offers a substantial energy reserve of 400Ah (10-hour rate), ensuring stable support during long power outages or power fluctuations.The battery uses a sturdy, opaque, impact - resistant ABS plastic casing. The battery cover is tightly connected to the casing and reliably sealed at the terminal area, effectively preventing leakage or overflow of the electrolyte and ensuring the safety of equipment and personnel. The battery cover is equipped with six liquid filling holes, through which electrolyte is injected during production. A pressure relief valve made of non - combustible materials is then installed. This design greatly enhances the product's fire and explosion safety, ensuring stability even in abnormal situations.
The core advantage of the MSB - 400 battery lies in its advanced internal structure and material technology.Both positive and negative plates are coated with a paste - like active material with a special formula, which significantly improves the battery's charge acceptance capability, allowing it to absorb and store electrical energy more efficiently. Combined with a unique electrolyte fixing system and gel technology, the electrolyte inside the battery is effectively stabilized. This not only maximizes the overall service life but also enables efficient gas recombination, ensuring the battery requires almost no maintenance throughout its entire lifecycle. The high - tech alloy used to manufacture the grid provides the battery with extremely high corrosion resistance, further ensuring its long - term stable operation in various environments.These technological innovations work together to enable MSB series batteries to have an expected service life of up to 12 years under normal operating conditions, complying with Eurobat's definition of long-life batteries.
In terms of physical parameters, the MSB-400 battery is compactly designed and flexible in installation. Its dimensions are 211 mm (length) × 176 mm (width) × 329 mm (height), with a weight of approximately 31.5 kg. The battery supports both horizontal and vertical installation methods, greatly facilitating the spatial layout of cabinets and battery racks. The standard configuration includes B6-type terminals; users can also choose optional terminal types such as I3-type according to actual wiring requirements.Its capacity performance is comprehensive. In addition to the nominal capacity of 400Ah at a 10-hour rate, it can provide 300Ah at a 3-hour rate and 220Ah at a 1-hour rate, meeting the power requirements at different discharge rates.
The application scenarios of the MSB-400 battery are extremely extensive, making it an ideal power source for telecommunication facilities, central computer rooms, and uninterruptible power supply (UPS) systems. In the renewable energy field, such as solar and wind energy storage systems, it can effectively store unstable green power. Meanwhile, it is also widely used in power supply networks and the power industry to provide backup power support for key nodes.In addition, MSB-400 can provide reliable power support for data processing centers, monitoring equipment at oil and gas extraction sites, fire protection and safety alarm systems, emergency lighting, video surveillance systems, access control management systems, and various medical equipment. It is also suitable for backup power in rural estates, hotels, and shops, as well as auxiliary power systems for electric vehicles. Its sealed structure, long float life, high capacity, and excellent safety features make it a solid backing for various industrial and commercial applications requiring high reliability and long-term operation.
