Product details
The B.B. Battery's BPS120-12 battery is an outstanding product in the BPS120-12BPS Series Valve-Regulated Lead-Acid (VRLA) battery, providing a 12V nominal voltage and a standard capacity of up to 120Ah. The products in this series have a wide capacity range from 5Ah to 230Ah, meeting power requirements of different scales. 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 reliably sealed, effectively preventing electrolyte leakage and external contamination.Six liquid filling holes are reserved on the battery cover, through which electrolyte is precisely filled during the production process, and then a pressure relief valve made of non-combustible material is installed. This design not only achieves maintenance-free operation without the need for regular electrolyte refilling, but also provides high-level fire and explosion safety, ensuring stable operation in various application environments.
The BPS120-12 battery adopts advanced Absorbed Glass Mat (AGM) technology, achieving efficient gas recombination, significantly reducing water loss, and allowing the battery to be installed in various directions such as horizontal and vertical, providing great flexibility for equipment layout.Its self-discharge rate is extremely low, with monthly capacity loss less than 3%, making it very suitable for scenarios requiring long-term standby or intermittent use. Both positive and negative plates of the battery are coated with a special paste coating, optimizing electrochemical performance. Under normal working conditions, this product, represented by BPS series batteries, has an expected service life of over 12 years, meeting the long-life definition under the Eurobat standard and providing long-term and reliable investment returns.
In terms of technical parameters, the BPS120-12 battery provides a nominal capacity of 120 Ah when discharged at the 20-hour rate to a cut-off voltage of 1.75 volts per cell.Its internal resistance is as low as 4 mΩ (when fully charged), capable of supporting instantaneous discharge currents of up to 800 amps (sustained for 5 seconds) and allowing a maximum charging current of 36 amps. The battery has a wide operating temperature range: 0°C to 40°C for charging, -20°C to 50°C for discharging, and a storage temperature range of -20°C to 40°C, suitable for various climate environments. The battery is standardly equipped with B4-type terminals, connected using M6 bolts and nuts, and I2-type terminals are available as an option. The recommended initial torque for all terminal connections is 5.5 N·m ±5%.The physical dimensions of the battery are 407 mm in length, 173 mm in width, 210 mm in container height, with a total height of 239 mm including terminals, and a weight of approximately 39.5 kg. It is easy to handle and install, and the side handle design further simplifies the installation process.
The discharge performance data of this battery is detailed. For example, at a cutoff voltage of 1.75 V per cell, it can provide approximately 1581 watts of power when discharged at a 30-minute rate. It is strongly recommended for applications requiring 30 minutes or longer backup time. Its extensive application fields include low-power uninterruptible power supplies (UPS), fire and safety alarm systems, emergency lighting, monitoring systems, access control, and various medical equipment.Meanwhile, it is also an ideal choice for power supply networks, the power industry, mining, oil and gas, telecommunications facilities, rural estates, hotel catering retail store equipment, renewable energy systems (such as solar and wind energy storage), and auxiliary power sources for electric vehicles. With its maintenance-free, high-safety, long service life, and wide applicability, B.B. Battery's BPS120-12 battery provides long-lasting and stable power support for critical equipment and systems.
