Product details
SH4.5-12L is a 12V integral sealed lead-acid battery from the SH4.5-12LSH series of B.B. Battery VRLA batteries, designed to provide reliable backup power for various critical equipment and systems. The battery case is made of sturdy, opaque impact-resistant ABS plastic. The battery cover is firmly connected to the shell, and the terminal area is sealed to ensure safe use. The terminal design varies by model; users can choose standard T1 terminals or optional T2 terminals as needed. The six holes on the battery cover are channels for filling electrolyte during production. After filling, a dedicated pressure relief valve is installed.These valves are made of non-combustible materials and can effectively release internal pressure, thus ensuring the battery has a high level of fire and explosion safety, making it an ideal choice for safety-conscious environments.
In terms of internal structure, the positive and negative plates of the battery are coated with a special paste-like active material, which optimizes the electrochemical reaction efficiency. The SH4.5-12L battery has excellent installation flexibility, supporting horizontal and vertical installation (inversion is prohibited), and can easily adapt to various narrow or irregular spatial layouts.Under normal operating conditions, the expected service life of this series of batteries can reach 5-7 years. Combined with its low self-discharge rate (capacity loss per month is less than 3%) and maintenance-free feature (no need for water replenishment), it can significantly reduce the total cost of ownership for long-term use. The battery adopts a sealed design without free acid, completely eliminating the risk of leakage, making it very suitable for installation near precision equipment or in places with frequent human activity.
In terms of performance, the SH4.5-12L battery is designed for high-rate discharge and can provide a high specific output power in short-time discharge modes. Its nominal capacity is 4.28 Ah at a 10-hour rate (C10), and the power output of each battery ranges from 108 to 168 watts.Specifically, for discharge power, under the condition of discharging to 1.3V per cell within 15 minutes, the entire SH series can provide a powerful output of 78 to 576 watts per unit. Therefore, it is particularly recommended for applications with a backup time of up to 60 minutes, ensuring quick and stable power supply when the main power is interrupted. According to the Eurobat standard, this battery is designed for long life, and its reliability and durability are recognized by the industry.
Due to its stable performance and safe characteristics, the SH4.5-12L battery is an ideal power source for numerous low-power and critical backup systems.It is widely used in uninterruptible power supply (UPS) systems, fire and safety alarm systems, emergency lighting and monitoring systems, as well as access control systems, ensuring that safety protection equipment operates uninterruptedly in any situation. In the medical field, it can provide backup power for important medical equipment, ensuring patient safety. In addition, it is also suitable for power supply networks, power industry facilities, as well as rural estates, hotels, and stores, serving as a reliable backup power source. Even in the auxiliary systems of electric vehicles, it can find its place. Its compact dimensions (length 151 mm/5.94 inches, width 51 mm/2.01 inches, height 94 mm/3.7 inches, total height 100 mm/3.94 inches) and a lightweight design of approximately 1.63 kg (3.59 lbs), making installation and handling extremely convenient.
