Product details
In the telecommunications facilities, medium and low power uninterruptible power supplies, and power network industries, there is a continuous and urgent need for stable and reliable backup power. The FTB155-12 (gassing) Valve-regulated Sealed Lead-acid Battery launched by B.B. Battery is a power solution carefully designed to meet these critical application scenarios. As a member of the FTB series, it is provided in a 12-volt form, with a nominal capacity ranging from 155 to 159 ampere-hours, depending on the discharge rate, for example, its 8-hour rate capacity is 155Ah, while its 10-hour rate capacity reaches 159Ah, capable of providing long-lasting and stable power support for the system.
One of the core advantages of this battery is its front-end design, where the terminals are located on the front of the battery.This innovative layout enables extremely convenient installation in standard 19-inch or 23-inch cabinets and racks, greatly optimizing the spatial arrangement of the battery pack and bringing unprecedented convenience to subsequent inspection, connection, and maintenance work. The battery case is made of sturdy, opaque, impact-resistant ABS plastic, combined with a ribbed design to ensure the integrity of the overall structure during installation and use. The battery cover is firmly connected to the case, and the terminal area is sealed to effectively prevent electrolyte leakage and external erosion. To facilitate handling and installation, the battery is also thoughtfully equipped with carrying handles.
At the technical level, FTB155-12 adopts advanced absorbent glass fiber separator technology, along with positive and negative plates coated with paste-like materials, enabling efficient gas recombination reactions, thereby minimizing water loss and significantly extending the battery's service life. In normal operating conditions, its expected float life can reach 15 years, meeting the 'very long service life' standard defined by Eurobat. The six holes on the battery cover are used for filling electrolyte during the production process, after which a one-way self-sealing safety valve made of non-combustible materials is installed.This pressure relief valve design not only ensures the safe release of internal pressure but also provides high-level fire and explosion safety protection. The built-in flame suppressor further enhances usage safety. The battery has high installation flexibility, supporting both horizontal and vertical placement.
With its compact dimensions—length 560 mm (≈22.05 inches), width 125 mm (≈4.92 inches), height 290 mm (≈11.42 inches)—and a weight of approximately 55.4 kg (≈122.1 lb), it can be efficiently integrated into space-constrained cabinets.This battery design supports easy configuration into a 48VDC system within a standard 19-inch rack, making it ideal as a backup power source for telecom base stations, broadband network nodes, railway signaling systems, and central computer rooms of data centers.
In addition to the above core applications, the FTB series has a very wide range of applications. It is also a reliable power guarantee for oil and gas extraction sites, fire and safety alarm systems, emergency lighting and 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 shops, it can also play an important role, and even serve as auxiliary power for electric vehicle-related facilities. With its long lifespan, high safety, and flexible installation characteristics, the FTB155-12 battery provides users with a reliable power option in various harsh environments.
