Product details
Among many backup power solutions, the HR5.8-12HR series VRLA batteries stand out with their excellent reliability and adaptability. As a star product of B.B. Battery, this series offers an overall voltage selection from 6V to 12V, with a wide power range of 96W to 1800W per single battery, meeting various power requirements from light to heavy loads.
The durability of the battery starts with its sturdy physical structure. The outer case is made of high-quality impact-resistant ABS plastic, effectively protecting internal components.The firm connection between the battery cover and the outer case, along with the precise sealing of the terminal area, together form the first line of defense against leakage, ensuring a safe usage environment with no free acid leakage. The terminal design varies by specific model, providing flexible connection options. Notably, the six holes on the battery cover are channels for filling the electrolyte during production. After completion, the critical pressure relief valve will be installed. These valves are made of non-combustible materials and can effectively release accumulated internal gases, thereby significantly improving the battery's fire and explosion safety levels, giving users more peace of mind during use.
In terms of core electrochemical design, the HR5.8-12HR series also spares no effort.Both positive and negative plates adopt advanced paste coating technology, combined with absorbent glass fiber separator technology, achieving efficient internal gas recombination, truly maintenance - free, and users don't need to worry about adding electrolyte. This design also optimizes it for high - rate discharge scenarios, especially in short - duration discharge modes of 5 to 15 minutes, where its power density is about 30% higher than traditional BP series batteries, enabling powerful current output instantly. For example, the battery model HR5.8 - 12, under a 15 - minute discharge rate, can achieve 231 watts per cell, with a 10 - hour rate rated capacity of 5.3 Ah, and a weight of approximately 1.88 kg, with a compact size (about 90mm x 70mm x 102mm), creating conditions for its flexible installation. The battery supports horizontal and vertical installation (excluding inversion), providing great convenience for the limited space layout inside the cabinet.
In terms of performance, this series of batteries can provide extremely high specific output power in short - discharge modes, making them very suitable for applications requiring instant high - current support. The official recommendation is to use it for scenarios with backup time not exceeding 60 minutes. Its discharge power range (under the condition of discharging to 1.3V per cell in 15 minutes) covers 96 to 1800 watts per unit.Under normal float charging conditions, the expected service life of HR series batteries can reach 10 years, meeting Eurobat's standards for long-life batteries. Its capacity ranges widely from 4 Ah to 75 Ah, with specific values depending on different discharge rate standards such as C2, C10, C20, etc. Users can choose according to their actual discharge requirements.
Due to its high reliability, maintenance-free feature, and flexible installation method, B.B. Battery HR series batteries have become an ideal power source for many critical systems.It is widely used in low-power devices and uninterruptible power supply (UPS) systems, providing uninterrupted protection for fire alarm and security alarm systems, ensuring that emergency lighting and monitoring systems take over immediately when the main power is interrupted. In fields where there is no room for error such as access control and medical equipment, it is also a reliable energy back-up. In addition, its application scenarios extend to telecommunication facilities, power supply networks, on-site equipment for oil and gas extraction, rural estates, security systems in hotels and stores, as well as auxiliary or traction power sources for various electric vehicles. Whether it is to deal with sudden power outages or provide stable power for important equipment, HR5.8-12HR series VRLA batteries all promise a ten-year lifespan, quietly providing strong and lasting power support.
