Product details
BPL33-12 Standard Type is a 12V maintenance-free valve-regulated lead-acid battery, a widely recognized product from B.B. Battery's BPL series. This series features an integrated design with capacities ranging from 3.3 to 210 Ah, meeting power needs for various scenarios. The battery casing is made of sturdy and durable impact-resistant ABS plastic, providing excellent physical protection. The battery cover is tightly connected to the casing, and the terminal area is specially sealed to effectively prevent electrolyte leakage and intrusion of external contaminants. The terminal design varies by series and model, ensuring reliable connection.
During the production process, the electrolyte is poured through six reserved holes on the battery cover, followed by the installation of a dedicated pressure relief valve made of non - combustible materials. This design not only achieves maintenance - free operation without the need for regular water replenishment, but also ensures an extremely high fire and explosion safety level through efficient internal gas recombination reactions, eliminating the risk of free acid leakage during battery use.Inside the battery, both positive and negative plates are coated with high - performance paste - like active materials. Combined with absorbent glass fiber separator technology, they achieve excellent cycle performance and a low self - discharge rate. Under normal usage conditions, the expected service life of BPL series batteries can reach 12 years, meeting Eurobat's standards for long - life batteries.
In terms of installation, BPL33 - 12 offers great flexibility, allowing installation in both horizontal and vertical directions, which provides convenience for users to save space and optimize equipment layout. However, note that inverted use is prohibited. Its specific technical parameters are clearly defined: nominal voltage is 12 volts, standard capacity at 20 - hour rate is 33 Ah, 28.05 Ah at 5 - hour rate, and at 30 - minute rate, it provides 16.With an energy capacity of 5 Ah, it is particularly suitable for applications requiring a backup time of 30 minutes or longer. The battery weighs approximately 11.5 kilograms (25.36 pounds) with compact dimensions: length 195 mm (7.68 inches), width 129 mm (5.08 inches), height 155 mm (6.1 inches), and total height 179 mm (7.05 inches). The standard terminal type is B7, located on the top for easy wiring.
BPL33-12 and its series are ideal power solutions for numerous critical equipment and systems. It is widely used in low-power uninterruptible power supply systems, fire and safety alarm systems, emergency lighting, and security monitoring systems, providing reliable protection for safe operation.In the medical field, it is commonly used in electronic medical devices and electric wheelchairs. Additionally, it is also suitable for access control systems, golf carts, electric lawn mowers, and various commercial equipment. In the industrial and energy sectors, its applications include power supply for equipment in telecommunications facilities, power networks, mining, oil, and gas industries, as well as backup power for rural estates, hotels, catering, and retail stores. In the renewable energy sector, such as solar and wind energy storage systems, and auxiliary power for some electric vehicles, it also performs exceptionally well.
