Product details
The BP4.5-12BP series B.B. Battery VRLA battery is a 12V maintenance-free valve-regulated lead-acid battery, providing stable and reliable power support. The battery case is made of sturdy impact-resistant ABS plastic, effectively protecting the internal structure. The battery cover is tightly connected to the case and sealed in the terminal area, ensuring the overall structure is sturdy and durable. Terminal design varies by series and type; the standard configuration is T1 type terminal, located at position 3, with T2 type available as an option, providing users with flexible connection choices.The six holes on the battery cover are used for electrolyte filling during the production process. After completion, a pressure relief valve made of non - combustible materials is installed. This design significantly improves the battery's fire and explosion safety levels, ensuring safety during use.
Regarding performance, this battery has low self - discharge characteristics, with a monthly self - discharge rate below 3%, making it suitable for ready use after long - term storage. Its nominal capacity is 4.5 Ah at a 20 - hour rate, 4.28 Ah at a 10 - hour rate, and 3.83 Ah at a 5 - hour rate, which can meet the power requirements under different discharge rates. The battery supports both vertical and horizontal installation methods, providing great convenience for users in arranging equipment in limited spaces.With a compact design, measuring 90 mm in length, 70 mm in width, and 102 mm in height (total height 106 mm), combined with a lightweight weight of approximately 2.7 kg, it can be easily integrated into various devices.
The BP4.5 - 12 battery is specifically designed for application scenarios requiring medium and low power backup power. It is an ideal choice for uninterruptible power supply (UPS) systems in home and commercial environments, especially for configurations with a recommended backup time of 30 minutes or longer. Meanwhile, this battery is also widely used in fire and safety alarm systems, emergency lighting devices, monitoring systems, electronic access control systems, and various medical electronic equipment, providing uninterrupted power support for critical systems.In the field of consumer electronics, it can also provide long-lasting power for products such as electronic doorbells, toy cars, and small fans.
With the technical process of coating both positive and negative plates with a special paste coating, as well as maintenance-free and leak-proof features, users do not need to worry about electrolyte replenishment, making it easy and convenient to use. Under normal usage and maintenance conditions, the expected service life of BP series batteries can reach 8 to 10 years, meeting Eurobat's standard definition of long-life batteries. From 1.The wide capacity range from 1 Ah to 230 Ah covers diverse needs, enabling BP series batteries to be not only applicable to civil and commercial fields but also capable of serving as auxiliary power sources in power grids, power industries, mining, oil and gas, rural properties, hotels, malls, and even some electric vehicles, demonstrating its extensive application potential and reliable performance.
