Product details
When you need reliable backup power support for critical systems, B.B. Battery HR8-12HR series VRLA batteries offer a robust and efficient solution. This series is manufactured in 6-volt and 12-volt configurations, with a wide power range per battery from 96 watts to 1800 watts, enabling flexible adaptation to different power demands. The battery case is made of opaque, impact-resistant ABS plastic, ensuring structural durability. The battery cover is securely connected to the shell, and the terminal area is sealed to effectively prevent leakage. The terminal design varies according to the specific battery model to meet diverse connection requirements.During the production process, six holes on the battery cover are used to fill the electrolyte, followed by the installation of a dedicated pressure relief valve made of non-combustible materials. This design not only ensures the safe release of internal battery pressure but also provides a high level of fire and explosion safety protection, giving users greater peace of mind. The positive and negative plates of the battery are coated with a special paste-like coating, combined with absorbed glass mat (AGM) separator technology, which enables efficient internal gas recombination. This allows the battery to truly meet the maintenance-free standard, requiring no water addition throughout its entire service life, with no free acid, and completely eliminating the risk of leakage.
HR8-12HR series batteries are specifically designed for high-rate discharge scenarios and can provide extremely high specific output power in short-time discharge mode. Taking the HR8-12 model as an example, under the condition of discharging to 1.3V per cell in 15 minutes, the rated power reaches 321 watts, and the rated capacity at a 10-hour rate is 7 ampere-hours. Its power density is particularly outstanding. At discharge rates of 5 to 15 minutes, it is about 30% higher than the comparable BP series, meaning it can provide stronger and more efficient power support in applications requiring rapid release of large amounts of electricity. The battery has extremely flexible installation methods, supporting horizontal and vertical installation (except inversion), which greatly facilitates cabinet and space layout.
In terms of lifespan, HR series batteries have an expected service life of up to 10 years under normal operating conditions, complying with Eurobat's long-life battery standards. Its capacity range is wide, from 4 ampere-hours to 75 ampere-hours, with specific values depending on different discharge rate standards such as C2, C5, C8, C10, C20, C100. It can stably handle both short-term peak power demands and long-term continuous power supply.
This battery is an ideal power source for many key equipment and systems. It is very suitable for low-power devices and uninterruptible power supply systems, providing power outage protection for data centers and server rooms.Meanwhile, in safety-critical fields such as fire and safety alarm systems, emergency lighting, and monitoring systems, its reliability is crucial. It is also widely used in access control systems, various medical equipment, as well as power supply for instrumentation in telecom facilities and oil and gas extraction sites. For security and checkout systems in rural estates, hotels, and stores, or as a power source for electric toy cars, fishing lights, and their boosters, the HR8-12HR battery can provide long-lasting and stable energy.It is especially recommended for applications with backup time not exceeding 60 minutes. Within the discharge range of 15 minutes to 1 hour, it can maximize its high power output advantage, ensuring important equipment continues to operate during grid outages.
