Product details
In the field of power supply and backup power, MSU series VRLA batteries are highly trusted for their excellent reliability and wide application adaptability. In particular, the MSU-300 model, as a member of this series, adopts advanced sealed valve-regulated lead-acid technology, ensuring stable and long-lasting power support in various critical scenarios such as telecommunications, data centers, and even renewable energy systems.
The core advantage of this battery lies in its sturdy and durable design and long-life characteristics. Its shell is made of opaque impact-resistant ABS plastic, and the battery cover is tightly connected to the shell with enhanced sealing at the terminal area, effectively preventing the risk of electrolyte leakage or overflow.This fully sealed structure not only enhances safety but also allows the battery to be flexibly installed in horizontal or vertical positions, providing convenience for computer rooms and equipment cabinets with different spatial layouts. The six filling holes on the battery cover are used for filling the electrolyte during production, and then a pressure relief valve made of non-combustible materials is installed. This design ensures an extremely high fire and explosion safety level, giving users more peace of mind during use.
MSU-300 has a nominal voltage of 2V and a nominal capacity of 300Ah (measured based on a 10-hour rate). Its compact size design—length 171mm, width 151mm, height 330mm, total height 358mm, weight approximately 1.9 kg —— enabling efficient deployment even in limited equipment space. Terminals are available with standard B6 type, and I3 type is also supported as an option to meet different wiring requirements.
Technological innovations are the cornerstone of the long service life of the MSU series. Both positive and negative plates are coated with paste - like active material with a special formula, which significantly improves the battery's charge acceptance capability and ensures fast and efficient charging performance.The high - tech alloy used in manufacturing the grid provides the battery with extremely high corrosion resistance. With the unique electrolyte immobilization system combined with absorbent glass fiber separator technology, efficient recombination of internal gases is achieved, and electrolyte loss is minimized to the greatest extent. This extends the expected service life of the battery under normal floating operation conditions to 15 to 18 years, which falls into the long - service - life category according to the Eurobat standard.
This makes the MSU - 300 an ideal choice for applications with extremely high requirements for power continuity. It is widely used in telecommunication facilities, uninterruptible power supply (UPS) systems, and data center computer rooms, providing critical backup power for servers and network equipment.In power supply networks and the power industry, it functions as a reliable energy storage unit.
At the same time, in the renewable energy sector, such as solar and wind power generation systems, it can effectively store unstable green energy. Its applicability also extends to a wide range of diverse fields including oil and gas extraction, fire safety and security alarm systems, emergency lighting and video surveillance, access control, medical equipment, rural villas, hotels and shopping malls, as well as electric vehicle charging infrastructure.
In conclusion, MSU-300 is not only a power product with reliable parameters but also an energy solution that integrates safe design, long-term service life, and wide adaptability.Through a series of technical details such as a sealed structure, anti-corrosion alloys, fixed electrolyte system, and special active materials, it ensures excellent performance in various harsh usage scenarios, serving as a solid support for maintaining continuous power supply and system stability.
