Product details
MPL55-12 Standard is a standard model of B.B. Battery's MPL series valve-regulated sealed lead-acid (VRLA) batteries, providing an overall voltage of 12 volts and a nominal capacity of 53 ampere-hours (10-hour rate). This battery is designed for medium to low power applications requiring reliable backup power, and with its stable performance and maintenance-free characteristics, it has become an ideal choice for numerous critical systems.
The battery shell is made of sturdy impact-resistant ABS plastic, ensuring good physical protection during handling and daily use.The battery cover is tightly connected to the case, and the terminal area is sealed to effectively prevent electrolyte leakage, achieving true acid-free and leak-proof characteristics. According to user requirements, MPL55-12 Standard offers two terminal types for selection: B5 and I2. The standard thickness of the B5 terminal is 224 mm, while the I2 terminal is 207 mm, providing flexibility for users to install in compact spaces. The six holes on the battery cover are used for electrolyte filling during the production process, followed by installing a pressure relief valve made of non-combustible materials. These valves automatically open when the internal pressure of the battery is abnormal, ensuring a high level of fire and explosion safety and giving users greater peace of mind during use.
In the core electrochemical design, both the positive and negative plates of MPL55-12 Standard are coated with a special formulated paste-like active material, combined with Absorbed Glass Mat (AGM) technology. This technology not only fixes the electrolyte in the separator to prevent leakage, but also enables efficient recombination of internal oxygen, thereby significantly reducing water loss and achieving a lifetime maintenance-free effect, so users don't need to worry about daily water addition.This structure simultaneously endows the battery with extremely low internal resistance and ultra - high power output performance, enabling it to perform exceptionally well in short - duration, high - current discharge modes. It is particularly suitable as a backup battery for uninterruptible power supplies (UPS), providing stable power for data centers, servers, and critical network equipment during mains power outages, with a typical recommended backup time of up to 60 minutes.
Besides data center and UPS applications, its reliable power supply is also widely applicable to telecommunication facilities, cable TV network nodes, monitoring and control systems in power plants, and some medical equipment in hospitals. For the renewable energy sector, such as the energy storage part of solar and wind power generation systems, the MPL55 - 12 Standard is also an economical and efficient choice.Additionally, it can also provide long - lasting power for emergency lighting, security video surveillance, and access control systems, ensuring safety without worry. In transportation, it can be found in golf carts, small ships, and some special electric vehicles. Its robust design allows horizontal and vertical installation (strictly no inversion) and is equipped with a carrying handle, greatly facilitating deployment in various environments, whether it's remote sites for oil and gas extraction, rural estates, hotels, or stores.In terms of performance parameters, the single-cell Wh capacity of this battery at the 15-minute rate is 220 Wh, with overall dimensions of 228 mm (length) × 139 mm (width) × 200 mm (height) and a weight of approximately 17.8 kg. Under normal float charging conditions, the MPL series batteries can reach an expected service life of 12 years. Combined with the wide capacity range selection from 55 to 155 Ah, it provides users with long-term and reliable investment protection. Whether for ensuring the continuity of critical business operations or supporting off-grid energy systems, the MPL55-12 Standard battery demonstrates excellent value with its practical functions, flexible application scenarios, and long service life.
