Product details
MSB-400 (2V, 400Ah) is a high-performance valve-regulated sealed lead-acid battery in the B.B. Battery MSB series. The series is manufactured in 2V units, with capacities ranging widely from 200Ah to 3000Ah. It is developed to meet the high requirements of power supply networks, the power industry, and telecommunication applications, and is renowned for its long float life and high capacity.
The battery's case is made of opaque and impact-resistant ABS plastic, with a sturdy and durable structure. The battery cover is firmly connected to the case and sealed at the terminal area to ensure overall airtightness. The terminals are designed according to specific models, offering strong applicability.The battery cover is designed with six holes for electrolyte filling during production, followed by the installation of a pressure relief valve made of non-combustible material. This design not only ensures a high level of fire and explosion safety but also reflects comprehensive consideration of the usage environment.
In terms of internal structure, the positive and negative plates of the MSB-400 battery are coated with a paste-like active material of a special formula, which provides good charge acceptance. Combined with the absorbed glass fiber separator (AGM) technology, efficient gas recombination is achieved, further enhancing the battery's stability and service life.Its unique electrolyte fixing system, using gel technology, effectively fixes the electrolyte, eliminating the risk of leakage or overflow, thereby maximizing the service life.
In terms of key technical parameters, the nominal voltage of MSB-400 is 2V. Its nominal capacity performs excellently at different discharge rates: 400Ah at 10-hour rate, 300Ah at 3-hour rate, and 220Ah at 1-hour rate. The battery's physical dimensions are designed to be compact, with length, width, and height of 211mm, 176mm, and 329mm (or 8.31 inches, 6.92 inches, and 12.95 inches) respectively, with a total height of 357mm (14.06 inches) including terminals. The weight is approximately 31.5 kilograms (69.4 pounds), making it easy to install and deploy.The battery supports both horizontal and vertical installation methods, providing flexibility for the space layout of machine rooms and cabinets.
Benefiting from the high-tech alloy used in manufacturing the grid, MSB-400 has high corrosion resistance. Under normal working conditions, its expected service life can reach 12 years, meeting Eurobat's definition of a long-life battery. These characteristics make it an ideal power source choice for numerous critical applications.
MSB series batteries, including the MSB-400 model, are very suitable for telecommunication facilities, central machine rooms, and uninterruptible power supply systems, providing stable and reliable backup power for communication networks. In the renewable energy field, such as solar and wind energy storage systems, it can effectively store electrical energy and smooth the output.At the same time, it is also an important backup power source for power supply networks and the power industry. Additionally, its applications have been widely expanded to data processing centers, equipment power supply at oil and gas extraction sites, fire protection and safety alarm systems, emergency lighting and video surveillance systems, access control and management systems, as well as medical equipment power supplies. For backup power in rural estates, hotels, and stores, and even as a buffer power source for electric vehicle (EV) charging infrastructure, the MSB-400 can provide continuous and stable power support. Its sealed structure, high performance, and long lifespan together ensure reliable operation in various harsh usage scenarios.
