Product details
FTB155-12 (Central Ventilation Type) is a representative product of B.B. Battery's VRLA battery series. It provides reliable power support in the form of 12V single cells, with nominal capacity ranging from 155 to 159 Ah, meeting various long-term power supply requirements. This battery is deeply optimized for telecom applications, with long float life and high capacity characteristics emphasized at the initial design stage, making it a cornerstone for stable operation in key infrastructure such as communication base stations and central computer rooms.
Its sturdy outer shell is made of opaque, impact-resistant ABS plastic. The battery cover is firmly connected to the shell through a reliable process, and the terminal area is strictly sealed to effectively prevent electrolyte leakage and external environmental erosion. The terminal design is practical and reliable. The six holes on the battery cover are key channels for filling electrolyte during the production process. After completion, a dedicated pressure relief valve made of non-combustible materials is installed. This valve-regulated sealed lead-acid battery converts generated gas back into water through efficient gas recombination technology, significantly reducing electrolyte loss.The installation of a one-way self-sealing safety valve not only ensures stable internal pressure but also provides high-level fire and explosion safety protection, which is an important design to ensure long-term stable operation.
A significant advantage lies in its front-end design, where all accessible terminals are located on the front of the battery. This innovative layout allows the battery to be easily installed side by side in standard 19-inch or 23-inch cabinets and racks, greatly facilitating the compact arrangement of battery packs and subsequent maintenance, inspection, and replacement work. It is particularly suitable for machine room environments with neatly arranged spaces. At the same time, the carry handles designed on both sides of the battery also make the installation process more convenient.The ribbed structure of the shell ensures that the battery maintains excellent structural integrity during handling and use.
At the technical level, FTB155-12 adopts pasted positive and negative plates and absorbent glass fiber separator technology, which collectively ensure excellent electrochemical performance and safety. Its broad operating temperature adaptability and flexibility to support horizontal or vertical installation further expand its application scenarios. Under normal working conditions, this battery has an expected service life of up to 15 years, which meets Eurobat's standard definition for ultra-long life batteries, providing users with long-term value returns.
Specifically regarding product parameters, the nominal capacity of FTB155-12 at a 10-hour rate is 159Ah, 155Ah at an 8-hour rate, and it can still provide a strong output of 102.1Ah at a 1-hour rate, demonstrating its excellent high-rate discharge performance. Its dimensions are 560mm in length, 125mm in width, and 290mm in height, with a weight of approximately 55.4 kg, compact in structure and high in energy density. The standard-configured Type I3 terminals are reasonably positioned for easy connection.
It is precisely these reliable technical parameters and functional details that make FTB155-12 have an extremely wide range of application fields. It is not only an ideal choice for backup power in telecommunication facilities, broadband networks, and central machine rooms, but also a core component of medium and low-power uninterruptible power supply systems.In the power industry and power supply networks, it ensures the stable operation of key nodes; in railway signaling systems, it provides uninterrupted safe command power. In addition, its reliable performance extends to fire protection and safety alarm systems, emergency lighting, video surveillance systems, access control management systems, and various medical equipment. In the renewable energy field, such as solar and wind energy storage systems, and in backup power scenarios for rural estates, hotels, and stores, and even as auxiliary or backup power for electric vehicles, FTB155-12 can provide safe, long-lasting, and maintenance-free power support.
