Product details
The BP33-12 Handle Type battery is a reliable product in B.B. Battery BP series VRLA valve-regulated sealed lead-acid batteries. This series of batteries is manufactured in integrated forms of 4V, 6V, or 12V, with a wide capacity range from 1.0 Ah to 230 Ah, capable of meeting various power demand scenarios. As one of them, BP33-12, with its excellent performance and flexibility, has become an ideal power source for numerous critical applications.
The battery's case is made of sturdy and durable opaque impact-resistant ABS plastic, ensuring good physical protection.The battery cover is firmly connected to the shell, and the terminal area is effectively sealed, providing excellent leak-proof performance. There is no free electrolyte inside the battery, ensuring safe and reliable use. Its terminal design varies by series and type; BP33-12 provides a standard B7-type terminal and optional I2-type terminal, offering users flexibility in installation and connection. The six holes on the battery cover are channels for electrolyte filling during production. After filling, a pressure relief valve made of non-combustible material is installed. This design not only ensures the battery's maintenance-free feature (no need to supplement electrolyte) but also provides a high level of fire and explosion safety protection.
In terms of internal structure, both the positive and negative plates of the battery are coated with a special paste-like coating, which helps to improve its electrochemical performance and service life. Under normal operating conditions, the expected service life of BP series batteries can reach 8 to 10 years, meeting Eurobat's standards for long-life batteries. At the same time, the battery has low self-discharge characteristics, with a monthly self-discharge rate below 3%, allowing it to retain charge better during storage or standby periods.
The nominal voltage of the BP33-12 battery is 12 volts, and its capacity varies according to different discharge rates. Under a 20-hour rate discharge condition, its nominal capacity is 33 Ah; under a 10-hour rate, it is 31.35 Ah;At a 5-hour rate, it is 28.05 Ah. This multi-specification capacity marking provides an accurate basis for energy consumption calculations in system design. The battery has a compact size design: length 210 mm, width 129 mm, height 168 mm, total height 179 mm, and weighs approximately 11.25 kg. This compact design, combined with its support for both vertical and horizontal installation methods, allows it to flexibly adapt to spatial layout constraints inside various cabinets or equipment, greatly simplifying the installation and integration process.
With these technical features, the BP33-12 Handle Type battery is very suitable as the core energy storage unit for low-power uninterruptible power supply (UPS) systems, especially recommended for scenarios requiring backup time of 30 minutes or longer. It can provide stable and reliable backup power in telecommunication systems, various switchgear cabinets, security alarm systems, and medical equipment. Additionally, it is also a commonly used power or auxiliary power source in photovoltaic energy storage systems, emergency lighting equipment, and electric vehicles such as golf carts. Its application scope also extends widely to power grids, the power industry, mining, oil and gas industries, as well as places in rural real estate, hotels, and stores that require independent or backup power.Whether ensuring the continuous operation of critical systems or providing emergency power when the main power is interrupted, the BP33-12 can, with its advantages of long lifespan, high safety, and maintenance-free, provide reliable power solutions.
