Product details
MPL155-12 is an important product among the valve-regulated sealed lead-acid (VRLA) batteries in the MPL series launched by B.B. Battery. It provides power in a 12-volt overall form, and its capacity range covers a broad choice from 55 Ah to 155 Ah to meet energy needs in different scenarios. The battery's housing is carefully constructed from sturdy and durable opaque impact-resistant ABS plastic, ensuring its physical protection capability in complex environments. The battery cover and housing are firmly connected through a reliable process, and the terminal area is strictly sealed, effectively preventing electrolyte leakage and external contamination. The terminal design varies according to the specific model, balancing connection convenience and electrical safety. The battery cover is provided with six filling holes, through which the electrolyte is precisely filled during production, after which pressure relief valves made of non-combustible material are installed. This pressure relief valve design is crucial, as it significantly improves the battery's fire and explosion safety, providing additional safety assurance for equipment operation.
In terms of internal structure, the positive and negative plates of the MPL155-12 battery are both coated with high-performance paste active material, combined with absorbent glass fiber separator technology to achieve efficient gas recombination, effectively reducing water loss and thus truly achieving Maintenance Free operation, so users do not need to regularly replenish electrolyte for the battery. At the same time, this design ensures that there is no free acid liquid inside the battery, making it a reliable leak-proof battery. In addition, the battery adopts an extremely low internal resistance design concept, which enables it to provide excellent specific output power in short-distance discharge mode, making it very suitable for application scenarios with high instantaneous power requirements. Its low self-discharge rate characteristic is also outstanding, with capacity loss of less than 3% per month, ensuring that the battery can still maintain sufficient charge after long-term storage.
The MPL155-12 battery offers great flexibility in installation, supporting both horizontal and vertical installation orientations, but note that inverted use is prohibited, which provides convenience for users in equipment layout within limited space. Under normal operating conditions, the expected service life of this battery can reach 12 years. Combined with its Nominal Capacity of 150 Ah (10-hour rate) and its short-time high-power output capability of 620 W (15 minutes/cell), it makes it an ideal power solution for many critical fields. Its specific product parameters include: voltage 12 V, Weight approximately 45.5 kg (100.3 lb), and dimensions of length 344 mm (13.54 in), width 173 mm (6.84 in), and height 270.5 mm (10.65 in).
With these reliable technical parameters and functional details, the MPL155-12 battery is widely used in low-to-medium power uninterruptible power supply (UPS) systems, data processing centers, power supply networks, and power industry infrastructure. In telecommunications facilities, emergency lighting systems, video surveillance systems, and access control and management systems, it serves as a reliable backup power source, ensuring the continuous operation of critical equipment. At the same time, it is also suitable for medical equipment, renewable energy systems (such as energy storage units for solar and wind power generation), as well as cable television networks, power stations, and marine equipment. In other fields, such as golf carts, auxiliary equipment at oil and gas extraction sites, rural estates, emergency power protection for hotels and shops, and even auxiliary power systems for some electric vehicles, the MPL155-12 can provide stable and lasting power support. Especially in UPS applications requiring backup time of up to about 60 minutes, its high-power performance and long-life characteristics are fully utilized.
