Product details
As a representative product in B.B. Battery's HRL series, HRL33-12 is a 12V valve-regulated lead-acid battery. Its design essence lies in integrating high performance with broad applicability, serving as a reliable energy backup for numerous key equipment and systems. This battery uses an opaque impact-resistant ABS plastic case, which is sturdy and durable. The battery cover and case are combined through a secure connection process, and the terminal area is specially sealed to effectively prevent electrolyte leakage and ensure safe use. Depending on the specific model, the terminal design may vary to meet different wiring requirements.In the production process, the electrolyte is injected through six filling holes on the battery cover, followed by the installation of a special pressure relief valve made of non - flammable materials. This pressure relief valve not only regulates internal pressure but also ensures the battery has a high level of fire and explosion safety, providing additional peace of mind for users.
In terms of internal structure, both the positive and negative plates of HRL33 - 12 are coated with specially formulated paste active materials, combined with Absorbed Glass Mat (AGM) separator technology. This technology can efficiently achieve internal gas recombination, thus making the battery truly maintenance - free throughout its entire lifespan without the need for water addition by the user.At the same time, there is no free acid inside the battery, which fundamentally eliminates the risk of leakage. It has an excellent low self - discharge rate, with a monthly capacity loss of less than 3%, which means that even after months of storage, the battery can still retain most of its power and be ready for use at any time.
Installation flexibility is another major highlight. The battery supports horizontal and vertical installation, which greatly facilitates the internal space layout of the equipment.
HRL33 - 12 is specially optimized for high - rate discharge scenarios. Under short - time high - power discharge conditions of 5 to 15 minutes, its power density is 30% higher than that of the traditional BP series batteries, and it can release strong electrical energy in a short time. Specifically, its discharge power (discharged to each cell at 15 minutes with 1.3 volts, covering a wide range from 132 to 5205 watts per unit. This makes it especially suitable as the core power source for uninterruptible power supply (UPS) systems, which can instantly take over when the grid is powered off, providing continuous and stable power buffering for connected equipment. The recommended backup time is up to 60 minutes, making it an ideal choice to ensure continuous operation of critical loads such as data center servers, financial transaction systems, and medical monitoring equipment without power interruption.
In terms of capacity, the nominal capacity of HRL33-12 is 31 Ah (based on the 10-hour rate discharge standard, i.e., C10). According to the Eurobat standard, the expected service life of this series of batteries under normal working conditions is as long as 12 years, placing it in the category of long-life batteries.Its compact design has dimensions of 175 mm in length, 166 mm in width, and 123 mm in height, with a net weight of approximately 10 kg (22.05 lbs), making it easy to integrate into various cabinets or equipment. The standard configuration is B1-type terminals, and users can also choose to select T2 or I1 type terminals as needed.
With stable and reliable performance, HRL33-12 has extremely wide application scenarios. It is not only the cornerstone of medium and low power UPS, data processing centers, and telecommunications network power supply, but also a reliable backup power source for power industry control and protection systems, emergency lighting systems, security video surveillance, and access control systems. In the medical field, it can provide uninterrupted power support for various medical equipment.Meanwhile, it can also be well integrated into renewable energy systems, such as energy storage units for solar and wind power generation, to smooth out power output. Additionally, it can be seen in remote sites for oil and gas extraction, rural manors, backup power sources for hotels and shops, and even auxiliary power systems for some electric vehicles. In conclusion, with a long lifespan of 12 years, maintenance-free convenience, high power output, and flexible installation methods, HRL33-12 provides solid power support for the continuous and stable operation of various industries.
