Product details
BP5-12 is a 12V maintenance-free lead-acid battery in the BP series of B.B. Battery VRLA batteries, with overall design centered on reliability and safety. The battery case is made of sturdy opaque impact-resistant ABS plastic. The battery cover is firmly connected to the case, and the terminal area is specially sealed to effectively prevent electrolyte leakage. Terminal design depends on the specific series and type, providing users with flexible connection options. During production, the electrolyte is injected through six holes on the battery cover, and then a pressure relief valve made of non-combustible materials is installed. This pressure relief valve design ensures a high level of fire and explosion safety, which is a key guarantee for the battery's safe operation.
In terms of internal structure, both the positive and negative plates of BP5-12 are coated with a special paste-like coating, which not only improves electrochemical performance but also extends the battery's service life. According to the Eurobat standard, the BP series batteries have an expected service life of 8 to 10 years under normal operating conditions. The battery supports both vertical and horizontal installation methods, providing great convenience for users when arranging in equipment or cabinets with limited space. Meanwhile, it has excellent low self-discharge characteristics, with a monthly self-discharge rate of less than 3%, allowing the battery to maintain sufficient charge even after long-term storage.
The nominal voltage of BP5-12 is 12V, and its capacity varies according to different discharge rates.At a 20-hour rate discharge condition, the nominal capacity is 5Ah; at a 10-hour rate, it is 4.75Ah; at a 5-hour rate, it is 4.25Ah. Such clear capacity parameter labeling makes it convenient for users to accurately calculate and select models based on the device's specific power consumption and required backup time. The battery weighs approximately 1.8 kilograms (3.97 pounds). It has a compact size: length 90 mm (3.54 inches), width 70 mm (2.76 inches), height 102 mm (4.02 inches), total height 106 mm (4.17 inches). The standard terminal type is T1, located at position 3. T2 terminals are also available as an option to meet different wiring requirements.
B.B. batteries from the BP series are ideal choices for various low-power backup power applications.BP5-12 is particularly suitable for scenarios requiring 30 minutes or longer backup time. Its typical application areas include uninterruptible power supply systems, fire and safety alarm systems, emergency lighting and monitoring systems, access control systems, and various medical electronic devices. In addition, it is widely used in power supply networks, the power industry, mining, oil and gas industries, and provides stable power for rural real estate, doorbells in hotels and shops, toy cars, fans, etc. It even plays a role in auxiliary systems of some electric vehicles. The battery's maintenance-free feature means no need to replenish electrolyte throughout its service life. Its leak-proof design ensures no free electrolyte, making it safe and reassuring to use. From 1.A wide capacity range from 0Ah to 230Ah enables the BP series to comprehensively meet the diverse needs from micro electronic devices to small and medium-sized backup power systems. The BP5-12 is an excellent representative that balances performance and size among them.
