Product details
The MPL155-12 is a 12V integrated valve-regulated lead-acid battery from the MPL series, with a capacity range from 55 to 155 ampere-hours. This battery uses an opaque and impact-resistant ABS plastic shell, ensuring the product's sturdiness and durability. The battery cover is firmly connected to the shell, and the terminal area is carefully sealed, effectively preventing any leakage risk. Its terminal design varies according to specific models to meet the connection needs of different application scenarios. The battery cover is designed with six filling holes, through which electrolyte is poured during the production process, and then a pressure relief valve made of non-combustible materials is installed.This pressure relief valve not only ensures the safe release of internal battery pressure, but also significantly improves the battery's fire and explosion prevention safety ratings, providing users with reliable protection.
In terms of internal structure, the positive and negative plates of the MPL155-12 are coated with specially formulated paste-like active material. Thanks to advanced Absorbed Glass Mat (AGM) separator technology, the battery achieves efficient recombination of internal gases, thus achieving true maintenance-free operation. Users do not need to replenish the electrolyte during the entire service life, and there is no free acid, making it an excellent leak-proof battery.The product has an extremely low self-discharge rate, with monthly capacity loss of less than 3% under normal temperature storage, facilitating long-term storage. Its extremely low internal resistance design endows the battery with excellent high-power discharge performance, enabling it to provide high specific output power in short-duration discharge modes, especially suitable as the core power unit of an uninterruptible power supply system. It is generally recommended to use it in application scenarios where the backup time does not exceed 60 minutes to achieve optimal performance.
The MPL155-12 battery supports both horizontal and vertical installation orientations, providing users with flexible system integration solutions. However, note that inversion is prohibited.Under normal working conditions, the expected service life of this battery series can reach up to 12 years. With its long service life and wide capacity range of 55 to 155 Ah, it has become an ideal power source for many key areas. Its application fields are extensive, especially suitable for medium and low power uninterruptible power supply systems, data processing centers, power supply networks, telecom base station facilities, emergency lighting and video surveillance systems, access control and building management systems, as well as various medical equipment. In the renewable energy field, such as solar and wind energy storage systems, it also performs excellently.In addition, this battery is also commonly used for power assurance at oil and gas extraction sites, backup power for rural villas, hotels and shopping malls, as well as powering golf carts, cable TV equipment, and ships.
Specifically, for the MPL155-12 model, the nominal voltage is 12V, and it can provide a nominal capacity of 150 Ah under 10-hour rate discharge conditions. At high-power discharge at the 15-minute rate, the single cell's watt-hour capacity reaches 620 Wh. The weight of this model battery is approximately 45.5 kilograms, with dimensions of length 344 mm, width 173 mm, and height 270.5 mm, making the overall structure compact. The battery is equipped with standard I3 type terminals, facilitating safe and reliable electrical connections for users.
