Product details
As a representative model of B.B. Battery's BPL series, BPL28-12 is a lead-acid battery using valve-regulated sealed technology with a rated voltage of 12V. With its sturdy and durable structure and reliable performance, this battery has become an ideal choice for numerous key backup power application scenarios. Its shell is made of opaque and impact-resistant ABS plastic. The battery cover is firmly connected to the shell, and the terminal area is sealed to effectively prevent electrolyte leakage.The six filling holes on the battery cover are used to fill the electrolyte during the production process, followed by installing a pressure relief valve made of non - combustible materials. This design ensures the battery operates under high safety standards and significantly reduces the risk of fire and explosion.
In terms of internal structure, both the positive and negative plates of BPL28 - 12 are coated with a special paste - like coating, and absorbent glass fiber separator technology is adopted. This technology can efficiently achieve the recombination of internal gases, enabling maintenance - free operation without the need for water replenishment throughout its entire service life, while ensuring no free acid inside the battery and truly preventing leakage.The battery supports horizontal and vertical installation, providing great flexibility for equipment integration, but it should be noted that inversion is prohibited.
Its low self - discharge rate allows the battery to maintain charge for a longer period during storage.
In terms of performance parameters, the nominal capacity of BPL28 - 12 is 28 Ah, which is measured based on the 20 - hour rate discharge standard. Additionally, its 5 - hour rate capacity is 23.8 Ah, and under the 30 - minute rate discharge condition with high power demand, the capacity is 14 Ah. These specific capacity data, as well as the wide capacity range of the entire BPL series from 3.3 to 210 Ah, are based on different discharge rate standards such as C2, C5, and C10. Users can refer to the corresponding values according to the actual load conditions.The physical dimensions of the battery are 175 mm in length, 166 mm in width, and 125 mm in height, with a total weight of approximately 9.7 kg. Its standard terminal type is B1 with position code 7, and optional terminal types such as T2I1 with position code 9 are also available to meet different wiring requirements.
The BPL28-12 and the entire BPL series batteries are designed for scenarios requiring long-term reliable backup power. When the system requires a backup time of 30 minutes or more, using such batteries is particularly appropriate. Its expected service life of up to 12 years meets Eurobat's standards for long-life batteries, providing long-term protection for investments.Typical application areas include low-power uninterruptible power supply (UPS) systems, fire and safety alarm systems, emergency lighting and monitoring systems, access control, and various medical equipment. In addition, they also widely serve power grids, the power industry, mining, oil and gas, telecommunication facilities, rural estates, hotel, restaurant, and retail store equipment, renewable energy systems such as solar and wind energy, as well as auxiliary power for some electric vehicles. With its maintenance-free, safe, reliable, and flexible installation features, the BPL28-12 battery provides stable and long-lasting power support for these critical applications.
