Product details
MPL155-12 is a 12V valve-regulated sealed lead-acid battery from B.B. Battery's MPL series. This battery is manufactured as a single unit with a nominal capacity of up to 150Ah. It performs exceptionally well in short-distance high-power discharge modes and is very suitable as the energy storage core for uninterruptible power supplies. 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 effectively prevent electrolyte leakage, making it a truly leak-proof battery. The top-mounted terminals are designed for easy installation and connection.
In terms of internal structure, both the positive and negative plates of the MPL155-12 battery are coated with a special paste-like coating, combined with absorbent glass fiber separator (AGM) technology. This innovative technology can efficiently achieve internal gas recombination, ensuring the battery is completely maintenance-free throughout its entire lifecycle, and users do not need to add electrolyte to it. The six filling holes on the battery cover are sealed with dedicated pressure relief valves after production. These safety valves, made of non-combustible materials, form a critical explosion-proof device, greatly enhancing the safety level of use and effectively preventing fire and explosion risks.
This battery has excellent high-power performance, thanks to its extremely low internal resistance design, allowing it to provide high specific output power. In a 15-minute high-rate discharge test, it can provide 620 Wh of energy, making it very suitable for scenarios requiring backup time, such as the recommended use in UPS systems with a backup time not exceeding 60 minutes. Meanwhile, the battery has a very low monthly self-discharge rate, with capacity loss below 3%, making it easy for long-term storage.
The design of MPL155-12 fully considers installation flexibility, allowing users to install it horizontally or vertically, which provides convenience for different cabinet or space layouts, but note that it is forbidden to use it upside down.Its compact dimensions, with a length of 344 mm, width of 173 mm, height of 270.5 mm, and a weight of approximately 45.5 kg, allow it to adapt to various installation environments.
With an expected service life of up to 12 years and reliable performance, the MPL155-12 battery is an ideal power source for numerous key fields. It is widely used in medium and low power uninterruptible power supply systems, data centers, telecommunication facilities, power plants, and power grids in the power industry. Meanwhile, it is also suitable for the security field, such as video surveillance systems, access control management systems, and emergency lighting. In terms of renewable energy, it is a reliable energy storage partner for solar and wind energy systems.In addition, its stable power output also makes it suitable for medical equipment, cable TV networks, marine equipment, and even special electric vehicles such as golf carts, providing continuous power support for scenarios like oil and gas extraction, rural estates, hotels, and stores.
