Product details
The BP28-12BP series B.B. Battery VRLA batteries provide a stable and reliable power solution. This series of batteries is produced as a whole, with voltage ranging from 4V, 6V to 12V, and a wide capacity range from 1.0 Ah to 230 Ah, meeting diverse energy storage requirements.
The battery case is made of sturdy opaque impact-resistant ABS plastic, ensuring excellent physical protection. The battery cover is firmly connected to the case, and the terminal area is sealed to effectively prevent external erosion.The terminal design varies according to the specific series and type. For example, the BP28-12 model is standardly equipped with B1 type terminals (Position 7), and T2I1 type terminals (Position 9) are also available as options, providing users with flexible connection choices. The battery cover is equipped with six filling holes, which are used to fill the electrolyte during production, followed by the installation of a pressure relief valve made of non-combustible materials. This design not only enables maintenance-free operation without the need to replenish electrolyte, but also ensures a high level of leak-proof performance and fire and explosion safety.
In terms of internal structure, both the positive and negative plates are coated with high-performance paste coatings. Combined with advanced valve-regulated sealed technology, the battery has a monthly self-discharge rate of less than 3%, significantly extending its shelf life. The battery supports both vertical and horizontal installation methods. With its compact design, the dimensions are 175 mm (6.89 inches) in length, 166 mm (6.54 inches) in width, and 125 mm (4.92 inches) in height, with a total weight of approximately 9.6 kg (21.17 lbs), making it easy to flexibly deploy in various spatial environments.
The BP28-12 model is a 12V maintenance-free battery with a nominal capacity of 28 Ah at a 20-hour rate, 26.6 Ah at a 10-hour rate, and 23.8 Ah at a 5-hour rate, capable of providing long-lasting power support for devices. According to Eurobat standards, BP series batteries have an expected service life of 8 to 10 years under normal operating conditions, making them long-life battery products. Its wide capacity range (here and all capacity data are based on different discharge rates such as C2, C5, C8, C10, C20, C100, etc., varying by series) ensures performance under different discharge requirements.
This series of batteries is the ideal power source for low-power uninterruptible power supply systems, fire and safety alarm systems, emergency lighting, monitoring systems, access control, and various medical equipment. Meanwhile, it is also widely used in power supply networks, power industry, mining, oil and gas, rural real estate, hotels, shops, and electric vehicles as backup or main power sources. It is particularly recommended for application scenarios requiring a backup time of 30 minutes or more. Its reliable performance, flexible installation method, and long service life provide a reassuring guarantee for critical equipment and systems.
