BP28-12
The B.B.Battery BP28-12 VRLA battery is specifically designed for long-term backup power systems, featuring a 12V voltage and up to 28Ah capacity to meet the demands of critical scenarios like security alarms, emergency lighting, and medical equipment. Its impact-resistant ABS casing and sealed terminal design ensure complete leak-proof performance, supporting flexible vertical/horizontal installation for compact spaces like server rooms and cabinets. The built-in flame-retardant pressure relief valve enhances fire safety, while a monthly self-discharge rate below 3% guarantees reliable power during emergencies. With Eurobat-certified 8-10 years of ultra-long service life reducing replacement frequency, it is the preferred backup power solution for hotels, oil fields, and smart buildings.

Product details
The B.B.Battery BP28-12 series VRLA battery integrates industrial-grade safety standards into daily power backup, with its 12V voltage platform and multiple capacity gradients (28Ah at 20-hour rate/26.6Ah at 10-hour rate) precisely matching different equipment loads. The innovative ABS engineering plastic housing, designed with a compact 6.89-inch structure, demonstrates excellent adaptability in confined spaces such as fire control cabinets and access control panels. The unique grid paste formulation ensures stable output across a wide temperature range of -15°C to 40°C, while the T2I1 terminal type is compatible with mainstream power interfaces.The medical-grade leak-proof construction is IP55 certified, and the pressure relief valve assembly automatically cuts off the circuit under abnormal pressure, making it particularly suitable for hospital life support systems and oil platform explosion-proof environments. The lightweight 9.6kg body, combined with anti-slip patterns on the bottom, facilitates quick deployment in telecom base station towers or mobile energy storage vehicles. The 23.8Ah discharge characteristic at 5-hour rate ensures monitoring systems operate continuously for over 4 hours after power failure, and the included smart charger also enables energy management for photovoltaic off-grid systems.Product Features
