Product details
BPS120-12, as a representative model of B.B. Battery's BPS series valve - regulated lead - acid batteries, is a 12V integrated backup power solution with a rated capacity of 120 Ah, suitable for a wide range of scenarios requiring reliable long - term power support. This series of batteries has a capacity range from 5 to 230 Ah, providing flexible options for power needs of different scales. The battery case is made of sturdy impact - resistant ABS plastic, ensuring good physical protection performance. The battery cover is tightly connected to the case, and the terminal area is sealed to effectively prevent electrolyte leakage and external contamination.The standard B4 terminal is connected using M6 bolts and nuts, and the optional I2 terminal provides installation flexibility for users. The initial torque setting for the terminal hardware is 5.5 Nm ±5%, ensuring the firmness and safety of the connection.
In terms of internal structure, the positive and negative plates are coated with a special paste - like coating, combined with absorbent glass fiber separator technology, achieving efficient gas recombination reactions, significantly reducing water loss, and truly achieving maintenance - free operation without the need for regular electrolyte addition. After the six filling holes on the battery cover complete the filling process during production, pressure relief valves made of non - combustible materials are installed.This design not only ensures the safe release of pressure inside the battery but also greatly enhances the product's fire and explosion safety ratings, enabling it to operate stably in various environments.
The BPS120-12 battery performs exceptionally well, providing a nominal capacity of 120 Ah when discharged at a 20-hour rate until reaching a final voltage of 1.75V per cell. Its internal resistance is extremely low, only 4 milliohms when fully charged, helping to reduce energy loss. The battery supports a maximum discharge current of 800 Amperes for 5 seconds and a maximum charging current of 36 Amperes.A wide working temperature range makes it highly adaptable, with a charging temperature of 0 to 40°C, discharge temperatures ranging from -20°C to 50°C, and storage temperatures from -20°C to 40°C. The battery has an extremely low self-discharge rate, with monthly capacity loss less than 3%, making it suitable for long-term float charge standby. Its installation orientation is flexible, supporting horizontal and vertical placement, providing convenience for equipment integration. It is also equipped with a handle for easy handling and installation.
This battery is particularly recommended for applications requiring 30 minutes or longer backup time. Its design life exceeds 12 years, meeting Eurobat's definition of long-life batteries, making it an ideal choice for users seeking long-term investment returns.In actual discharge performance, with a cutoff voltage of 1.75V per cell, the battery can provide approximately 1581 watts at a 30-minute discharge rate and about 899.6 watts at a 1-hour rate. Detailed data can be found in the product discharge performance table.
The application areas of BPS120-12 are very extensive. It is a reliable core for low-power uninterruptible power supply systems, fire and safety alarm systems, emergency lighting, and monitoring systems. It is also widely used for power supply in access control, various medical equipment, as well as key equipment in telecommunications facilities, power industry, mining, oil, and gas industries.For scenarios such as rural estates, hotel catering retail store equipment, renewable energy systems such as solar and wind energy storage, and auxiliary power for electric vehicles, it is also an economical and efficient power choice. The product dimensions are 407mm in length, 173mm in width, 210mm in height, with an overall height of 239mm and a weight of approximately 39.5 kg, featuring a compact and sturdy structure.
