b.b.battery HR5.8-12(12V23W)

Product details

The B.B.Battery HR5.8-12 series VRLA batteries redefine backup power standards through technological innovation. This 12V sealed lead-acid battery utilizes impact-resistant ABS casing, combined with a free-acid-free design and T1/T2 terminal options, maintaining stable output even in harsh environments. Its core advantage lies in high-rate discharge capability—achieving a power density of 231W per cell under 15-minute discharge rate, a 30% improvement over traditional models, making it particularly suitable for emergency lighting, access control systems, and medical equipment (such as defibrillators and ventilators) that require rapid response.The battery internally employs paste-coated plates and AGM separator technology, achieving up to 99% gas recombination efficiency. Paired with a pressure relief valve made of flame-retardant materials, it ensures safe operation in environments ranging from -15°C to 50°C. With a compact design weighing only 1.88kg (90x70x102mm), it allows flexible installation in cabinets, mobile devices, or confined spaces. Its 10-year expected lifespan and Eurobat-certified long-cycle performance make it an ideal choice for unattended scenarios such as oil extraction base stations and communication towers. Typical applications include providing 15-minute critical power backup for data center UPS (supporting multiple discharge rates from C2 to C100) or serving as an auxiliary power source for electric vehicles to maintain onboard electronic systems.Users can select capacity configurations ranging from 5.3Ah to 75Ah based on specific needs, with quick circuit integration via 3.54-inch standard terminals, truly delivering reliable "plug-and-play" power assurance.
