Product details
In fields requiring high-reliability backup power, HR5.5-12, as a representative model of B.B. HR series valve-regulated sealed lead-acid batteries, provides a stable and powerful power solution. This battery is manufactured in a 12V integrated form, and its core design ensures excellent performance in various harsh environments. The battery case is made of sturdy, opaque, impact-resistant ABS plastic. The battery cover is firmly connected to the case, and the terminal area is specially sealed to effectively prevent leakage and corrosion. The terminal type is standard T1 or optional T2, specifically designed to meet the connection needs of different devices.During production, the electrolyte is filled through six dedicated holes on the battery cover, and then a pressure relief valve made of non-flammable materials is installed. This key component ensures a high level of fire and explosion safety during battery use, allowing users to deploy with peace of mind.
The HR5.5-12 battery performs exceptionally well, specifically designed for high-rate discharge, and can provide extremely high specific output power in short-time discharge mode. Its power density at the 15-minute discharge rate is about 30% higher than that of the comparable BP series. Under the condition of discharging to 1.3V per cell in 15 minutes, the rated power reaches 22W per cell. For scenarios requiring continuous power supply, its rated capacity at the 10-hour rate is 5 ampere-hours.The installation flexibility of the battery is another major highlight, supporting horizontal and vertical installation, which greatly facilitates the spatial layout of cabinets and equipment. Both positive and negative plates are coated with a special paste - like coating, combined with the absorbed glass mat (AGM) separator technology, achieving efficient internal gas recombination, truly maintenance - free, so users don't need to worry about daily water addition. Meanwhile, the design without free acid also makes it an ideal choice for leak - proof batteries.
The expected service life of this battery can reach 10 years under normal operating conditions, meeting Eurobat's definition of long - life batteries, which provides security for long - term investment.With its compact size design, measuring 90mm in length, 70mm in width, and 102mm in height, and weighing approximately 1.8kg, it can be easily integrated into space - constrained equipment. HR5.5 - 12 and the entire HR series have a power range of 96 to 1800 watts per unit, with a capacity span of 4 to 75 ampere - hours, which can flexibly adapt to various needs from low power to medium and high power.
In terms of application scenarios, the HR5.5 - 12 battery is an ideal choice for low - power devices and uninterruptible power supply (UPS) systems. It can provide critical power support for fire and safety alarm systems, emergency lighting, and security monitoring systems, ensuring that the security defense line never fails.In access control systems, critical medical equipment, and telecommunication facilities, it ensures smooth communication and life support. Additionally, it is also suitable for power supply networks, power industry automation control, on-site equipment for oil and gas extraction, rural estates, backup power for hotels and stores, and even as auxiliary power for electric vehicles. Whether in scenarios requiring up to 60 minutes of backup time or situations needing instantaneous high-power support, HR5.5-12 can reliably serve as main power or backup power, ensuring continuous and stable operation of critical business and services.
