BP28-12 bb battery12V28AHSuitable forUninterruptible power supplies,Security and safety systems,Emergency lighting and video surveillance systems,Access control and management systems,Medical equipmen
The B.B. Battery VRLA series BP28-12 features an impact-resistant ABS plastic casing, with non-combustible material used for the top pressure relief valve, ensuring minimized fire and explosion risks. This 12V maintenance-free battery supports horizontal/vertical dual-mode installation, weighing only 9.6kg, and its compact dimensions (175x166x125mm) fit narrow spaces. Through special grid design, it achieves a 28Ah capacity at 20-hour rate, with a monthly self-discharge rate below 3%, coupled with leak-proof technology to maintain electrolyte stability, making it particularly suitable for security alarm systems, medical equipment, and emergency lighting scenarios requiring over 30 minutes of backup power.

Product details
As a long-life power solution, the BP28-12 battery offers a cycle life of 8-10 years at 20°C, meeting Eurobat longevity standards. Its multi-gradient capacity design of 26.6Ah (10-hour rate) and 23.8Ah (5-hour rate) precisely matches varying load demands, while the included B1/T2I1 dual-terminal configuration caters to diverse wiring needs.The unique gas recombination technology minimizes electrolyte loss to near zero, combined with sealed terminal design for truly maintenance-free operation, making it particularly suitable for unmanned deployment scenarios such as oil & gas facilities, rural villas, and commercial hotels/supermarkets. This battery features a three-dimensional protection system with triple safety layers: impact-resistant casing against physical damage, built-in pressure relief valve for automatic internal pressure regulation, and paste-coated plates to prevent active material shedding. Operating temperature range spans -15℃ to 50℃, with flame-retardant separators effectively preventing short circuits.In demanding environments like EV charging stations and mine monitoring systems, its stable voltage output and high-rate discharge capability of 23.8Ah (5-hour rate) ensure continuous operation of critical equipment. When extended to smart access control and photovoltaic energy storage systems, the battery's compact dimensions (6.89-inch length and 4.92-inch height) fit standard cabinet installations. The 21.17-pound lightweight design facilitates mobile deployment, while optional terminal positions enable flexible wiring. Test data shows 92% capacity retention after three years under intensive use (three charge-discharge cycles weekly), providing reliable power backup for critical infrastructure like communication base stations and data center UPS systems.Product Features
