Product details
The BP28-12, BP series is a member of B.B. Battery's VRLA battery family. This series of batteries is produced in 4V, 6V, or 12V integral configurations, covering a broad capacity range from 1.0 to 230 Ah to meet diverse power requirements. This battery features an opaque and impact-resistant ABS plastic shell, with a sturdy and durable structure. The battery cover is firmly connected to the shell, with special sealing at the terminal area to ensure high safety and reliability. The terminal design varies by specific series and model, offering flexible options. The battery cover is equipped with six filling holes for electrolyte filling during production, followed by the installation of a pressure relief valve made of non-combustible materials.This design not only effectively prevents electrolyte leakage but also ensures high-level fire and explosion safety, giving users greater peace of mind.
The specific model of BP28-12 is a 12V maintenance-free valve-regulated sealed lead-acid battery. It is completely maintenance-free; users do not need to add electrolyte. It also has excellent leak-proof performance, ensuring no free electrolyte seeps out, making the installation and usage environment cleaner and safer. The battery features low self-discharge with a monthly self-discharge rate of less than 3%, allowing it to maintain sufficient charge even after long-term storage. Its design supports both vertical and horizontal installation methods, providing great flexibility for equipment integration and space layout.In terms of technical parameters, the nominal voltage of BP28-12 is 12V. Its capacity varies with different discharge rates: the nominal capacity is 28Ah at 20-hour rate, 26.6Ah at 10-hour rate, and 23.8Ah at 5-hour rate. The battery weighs approximately 9.6 kg (21.17 lbs). It has a compact size with dimensions of 175 mm (6.89 inches) in length, 166 mm (6.54 inches) in width, and 125 mm (4.92 inches) in height. The total height is consistent with the battery's own height, facilitating installation in limited spaces. The standard terminal type is B1, located at position 7. Additionally, users can choose T2I1 type terminals at position 9 to meet different connection requirements.
BP28-12 series battery is renowned for its excellent service life, with an expected lifespan of 8 to 10 years under normal operating conditions, complying with Eurobat's standards for long-life batteries. This makes it an ideal choice for various application scenarios requiring reliable backup power. It is particularly suitable for low-power uninterruptible power supply systems, fire and safety alarm systems, emergency lighting and monitoring systems, access control systems, and various medical devices. In addition, this battery is also widely used in power supply networks, the power industry, mining, oil and gas industries, rural real estate, hotels and stores, and even as auxiliary power for electric vehicles.For application scenarios requiring a backup time of 30 minutes or longer, we particularly recommend this series of batteries, which can provide stable and long-lasting power support.
