Product details
In the fields of telecommunications, data centers, and critical power support, a stable and reliable backup power source is the lifeline for maintaining the uninterrupted operation of systems. As a front-end battery designed for harsh applications under BB Battery, the FTB155-12FTB series, with its excellent performance and flexible design, has become the preferred power solution for many industries. This series of batteries is provided as 12V single cells with capacities ranging from 100 to 180 Ah. Among them, the FTB155-12 model has a nominal capacity of 159 Ah at the 10-hour rate and 155 Ah at the 8-hour rate, which can provide long-lasting and powerful power support for equipment.
The core advantage of this battery lies in its front-end design optimized for rack installation.The terminals are located on the front of the battery, allowing battery packs to be compactly arranged in standard 19-inch or 23-inch cabinets and racks. This design not only greatly saves valuable machine room space but also makes wiring, assembly, and subsequent maintenance and replacement work extremely simple, improving the manageability of the entire power system. The battery case is made of high-strength impact-resistant ABS plastic with a ribbed structure, ensuring excellent structural integrity and physical protection during transportation, installation, and use. For easy operation, the battery is also thoughtfully designed with carrying handles.
Technologically, the FTB155-12FTB adopts advanced valve-regulated sealed lead-acid technology.Its internal structure uses pasted positive and negative plates and absorbed glass fiber separators. This technology effectively promotes oxygen recombination, reduces water loss, and thus enables maintenance-free operation. The six filling holes on the battery cover are installed with one-way self-sealing safety valves after production. These pressure relief valves, made of flame-retardant materials, can precisely control internal pressure. While providing reliable exhaust, they also ensure high-level fire and explosion safety. The built-in flame suppressor further enhances safety. It is these carefully designed features that enable this series of batteries to have an expected service life of up to 15 years under normal float charging conditions, meeting Eurobat's definition of ultra-long life batteries.
In addition to its excellent physical and electrical design, its extensive environmental adaptability is also commendable. The battery supports both horizontal and vertical installation methods, providing flexibility for equipment layout under different site conditions. With its compact dimensions (length 560mm, width 125mm, height 277mm) and weight of approximately 55.4kg, it can be efficiently integrated into various systems. A typical application is supporting the construction of a 48V DC power system within a standard 19-inch rack, which is a common configuration for telecom and network equipment.
Therefore, the FTB155-12 FTB series battery has extremely wide application scenarios. It is undoubtedly an ideal backup power source for communication facilities such as telecom base stations, central computer rooms, and broadband network nodes.At the same time, it is also widely used in uninterruptible power supply systems with medium to low power ranges, providing power outage protection for sensitive equipment in industries such as finance and medical care. In the power industry, it can be used in power grid monitoring and control systems; in the transportation sector, it provides stable power for railway signaling systems. Additionally, its reliability is equally indispensable in on-site equipment for oil and gas extraction, fire and safety alarm systems, emergency lighting, video surveillance, access control systems, and medical equipment.In the field of renewable energy, such as solar and wind energy storage systems, and in off-grid or backup power solutions for rural villas, hotels, and stores, it can also play an important role. It can even power auxiliary systems of certain electric vehicles. In short, whether in demanding industrial environments or safety-related civil facilities, this battery provides reliable power protection with its long service life, high safety, and installation convenience.
