Product details
The SH4.5-12LSH series battery is a 12V integrated valve-regulated lead-acid (VRLA) battery launched by B.B. Battery. This series is known for its durability. Its shell is made of opaque impact-resistant ABS plastic. The battery cover is firmly connected to the shell, and the terminal area is sealed to ensure long-term stability and reliability. Depending on the specific model, the terminal design may vary; top-mounted terminals are a common configuration. The battery cover is equipped with six liquid injection holes for electrolyte filling during production, followed by the installation of a dedicated pressure relief valve made of non-combustible materials.These pressure relief valves effectively maintain internal pressure balance of the battery, preventing excessive gas accumulation, thus providing a high level of fire and explosion safety protection.
In terms of performance, the SH4.5-12LSH series is well-designed. Both positive and negative plates are coated with a pasty active material layer, ensuring excellent electrochemical reaction efficiency. The battery's single-unit power ranges from 108 to 168 watts and can provide high specific output power in short-time discharge mode. Its discharge performance is outstanding, for example, under the condition of discharging to 1.3V per cell within 15 minutes, each battery can provide 78 to 576 watts. Therefore, it is particularly recommended for applications requiring a backup time of no more than 60 minutes.The battery offers excellent installation flexibility, supporting horizontal and vertical installation, but note that it is prohibited to use it upside down. As a maintenance-free battery, it does not require regular water replenishment and adopts a free-acid-free design, fundamentally eliminating the risk of leakage. Its low self-discharge rate is also a highlight, with a monthly capacity loss of less than 3%, making it easy for long-term storage.
In terms of technical parameters, taking the SH4.5-12L model as an example, its nominal voltage is 12V, and the nominal capacity at a 10-hour rate (C10) is 4.28 Ah. The battery has a compact structure, with dimensions of 151 mm (length) x 51 mm (width) x 94 mm (height, total height 100 mm), and a weight of approximately 1.63 kg. The terminal offers a standard T1 type option.The batteries in this series have excellent cycle life and float charge life under normal working conditions. According to the Eurobat standard, they are classified as long-life batteries, with an overall expected service life of 5 to 7 years and a design life of up to 10 years. Its capacity and power output vary according to different discharge rates (such as C2, C5, C10, C20, C100) and cutoff voltage conditions, and are specifically optimized to meet high-rate discharge requirements.
The SH series batteries have a wide range of applications and are an ideal choice for various systems requiring reliable backup power. It is very suitable for powering low-power devices and uninterruptible power supply (UPS) systems to ensure that critical operations are not interrupted.In the security field, it is commonly used in fire alarm systems, security alarm systems, and monitoring systems to ensure the continuous operation of security equipment. Additionally, it can provide stable power support for emergency lighting, access control systems, and various medical equipment. Its applications also extend to a broader energy field, serving as a power supply network in remote areas, an auxiliary power source for the power industry, providing power security for rural estates, hotels, and retail stores, and even playing a role in some auxiliary systems of electric vehicles. With its high reliability, safety, and installation convenience, the SH4.5-12LSH series battery provides a long-lasting power solution for key equipment in numerous industries.
