Product details
BP3-12 is a high-performance 12V product in the BP series of VRLA batteries. With its excellent reliability and broad applicability, it has become an ideal power choice for numerous critical systems. This battery adopts an integrated design with a wide capacity range from 1.0Ah to 230Ah, capable of meeting the needs of different loads.
The battery shell is made of sturdy, opaque, impact-resistant ABS plastic, which is not only durable but also provides excellent physical protection. The battery cover is firmly integrated with the shell, and the terminal area is specially sealed to ensure overall airtightness.Terminal design varies by series and type. BP3-12 offers a standard T1 terminal type, positioned at the top for easy connection. Additionally, users can choose T2 as an optional terminal type based on actual installation needs, providing a flexible wiring solution.
During production, electrolyte is injected through six filling holes on the battery cover, followed by installing a pressure relief valve made of non-combustible material. This design is crucial as it effectively regulates internal pressure, preventing excessive gas buildup, thereby ensuring a high level of fire and explosion safety and giving users greater peace of mind.The battery employs a paste-type plate process, with both positive and negative plates coated with active materials, ensuring stable electrochemical performance.
A significant advantage is that the BP3-12 battery is completely maintenance-free; users do not need to regularly add electrolyte. It adopts a valve-regulated sealed design, achieving true leak-proof performance with no free electrolyte, making installation and placement cleaner and safer. The battery has an extremely low monthly self-discharge rate, less than 3%, meaning it can maintain its charge for a long time during storage and be ready for use at any time.Its installation flexibility is also a major highlight, supporting both vertical and horizontal installation methods, and can easily fit into various space-constrained cabinets or equipment interiors.
In terms of key performance indicators, the BP3-12 performs excellently. Its nominal voltage is 12 volts. In terms of capacity, under a 20-hour rate discharge condition, its nominal capacity is 3Ah; under a 10-hour rate, it is 2.85Ah; under a 5-hour rate, it is 2.55Ah. These capacity data based on different discharge rates (such as C20, C10, C5) provide precise basis for designing systems with different backup durations. According to the Eurobat standard, the BP series batteries have an expected service life of up to 8 to 10 years under normal usage conditions, placing them in the category of long-life batteries.Its compact size design: length 134 mm, width 67 mm, height 60 mm, total height including terminals is 66 mm, weight is approximately 1.32 kg, making it very easy to integrate and handle.
The BP3-12 battery is specially designed for scenarios requiring reliable backup power. It is particularly suitable for applications requiring backup times of 30 minutes or longer and is a core component of uninterruptible power supply systems. Meanwhile, it also serves as a reliable safeguard for fire and safety alarm systems, emergency lighting systems, security monitoring, and access control systems. In the medical device field, it ensures the continuous operation of critical equipment.In addition, it is also widely used in portable power packs, remote - controlled model cars and aircraft, as well as power supply networks, power industry, mining, oil and gas, country villas, hotels, and stores, and can even serve as an auxiliary power source for electric vehicles. Whether dealing with sudden power outages or powering mobile devices, the BP3 - 12 can provide stable and long - lasting power support.
