Product details
The B.B. Battery VRLA battery of the SH4.5-12LSH series is a well-designed 12V integrated sealed lead-acid battery, with each battery covering a power range of 108 to 168 watts, providing stable and reliable power support for various devices. Its casing is made of sturdy, opaque, impact-resistant ABS plastic, ensuring excellent durability and physical protection. The battery cover and casing are integrated through a secure connection, and the terminal area is specially sealed to effectively prevent leakage, while the specific design of the terminals is optimized according to different battery models.During the production process, the electrolyte is filled through six dedicated holes on the battery cover, and subsequently, relief valves made of non - flammable materials are installed on these filling ports. This key design not only ensures the safe release of internal battery pressure but also significantly improves the overall fire and explosion safety level.
Inside the battery, both the positive and negative plates use an advanced paste coating process, which helps to enhance the efficiency and consistency of electrochemical reactions. In terms of installation flexibility, this battery supports both horizontal and vertical installation positions, providing more convenience for users' spatial layout.Under normal working conditions, the SH series batteries demonstrate excellent reliability, with an expected service life of 5 to 7 years. Some models can even reach a service life of up to 10 years according to the Eurobat standard, making them a truly long - life power source option.
With its excellent performance, the SH series batteries have become an ideal choice for many low - power and uninterruptible power supply systems. It is widely used in fire and safety alarm systems, emergency lighting and monitoring systems, access control systems, and medical equipment that require stable power supply. Additionally, it is also a reliable guarantee for power grids, power industry facilities, rural estates, hotel stores, and auxiliary power supplies for some electric vehicles.
The advantages of this series of batteries are significant. Its 12V design with top terminals facilitates connection. In short - time discharge mode, it can provide a high specific output power, making it especially suitable as a backup power source during power outages, with a recommended backup time of up to 60 minutes. It has a wide range of discharge power; when discharged to 1.3V per cell in 15 minutes, each battery can provide 78 to 576 watts, meeting the instantaneous high - power requirements of different scenarios.
Taking the specific model SH4.5 - 12L as an example, it is a maintenance - free battery that does not require water replenishment throughout its entire service life, ensuring easy usage.Meanwhile, it adopts a free - acid - free design, making it a truly leak - proof battery with high safety. The battery has an extremely low monthly self - discharge rate, with a capacity loss of less than 3% per month, meaning it can retain most of its charge even after long - term storage. In terms of installation, it supports installation in any direction, providing great flexibility for users, but note that it is prohibited from being used upside down. Its internal structure is specially designed for high - rate discharge scenarios, enabling quick response to high - power demands.
Regarding key product parameters, the nominal voltage of the SH4.5 - 12L model is 12V, and the nominal capacity at a 10 - hour rate is 4.28 Ah. Its compact size design has a length of only 151 mm (approximately 5.94 millimeters (about 3.7 inches), width is 51 millimeters (about 2.01 inches), height is 94 millimeters (about 3.7 inches), total height with terminals is 100 millimeters (about 3.94 inches), weight is approximately 1.63 kilograms (3.59 pounds), making it easy to integrate into various devices. For terminals, it provides standard T1 type terminals, and T2 type terminals are available to meet different wiring requirements. The battery's capacity and power values vary according to different discharge rates, such as C2, C5, C8, C10, C20, C100, etc., and the power type also corresponds to different cut-off voltages, such as discharging to 1.3 V per cell in 15 minutes or 1.6 V per cell, users can refer to the corresponding technical specifications according to specific application scenarios when selecting models.
