Product details
BP series valve-regulated sealed lead-acid batteries are provided in an integrated form with multiple voltage specifications to meet different application requirements, including BP4.5-12 is the representative of the 12V model. This battery adopts an opaque impact-resistant ABS plastic shell to ensure mechanical strength and durability. The battery cover is firmly connected to the shell. The terminal area is sealed to effectively prevent leakage. According to the model, the terminal type is standard T1 with position 3; T2 terminals can also be optionally equipped to meet different connection requirements
The battery cover is provided with six filling holes, through which electrolyte is added during production. Then a pressure relief valve made of non-combustible material is installed. This design not only ensures the battery is maintenance-free without the need for electrolyte supplementation, but also provides a high level of fire and explosion safety. Preventing excessive internal pressure. Both the positive and negative plates inside the battery are coated with a special paste-like coating. This process, combined with the leak-proof design, ensures no free electrolyte. It supports the battery to be flexibly installed vertically or horizontally, adapting to various space constraints
In terms of electrical performance, BP4.BP5-12 exhibits stable capacity output. Its 20-hour rate nominal capacity is 4.5 Ah, 10-hour rate is 4.28 Ah, and 5-hour rate is 3.83 Ah. This multi-rate capacity characteristic enables it to adapt to different discharge requirements. The battery has low self-discharge, with a monthly self-discharge rate of less than 3%, making it easy to use after long-term storage. Under normal working conditions, the expected service life of BP series batteries can reach 8-10 years, meeting Eurobat's definition of long-life batteries.
This battery is compact in size: 90 mm long, 70 mm wide, 102 mm high, with an overall height of 106 mm. The weight is approximately 2.7 kg, making it easy to integrate into various devices. Its capacity ranges from 1.0 Ah to 230 Ah, covering a wide range. BP4.BP5-12 is particularly suitable as a low-power backup power source. It is recommended for scenarios requiring 30 minutes or longer backup time. Typical applications include uninterruptible power supply systems, fire and safety alarm systems, emergency lighting, monitoring systems, access control systems, and small equipment such as electronic doorbells, toy cars, and fans. It is also widely used in power grids, the power industry, mining, oil and gas industries, rural real estate, hotels, stores, and medical equipment fields, providing reliable power support for critical operations.
