Product features

Maintenance free Design:  The maintenance free design that does not require adding water greatly reduces the complexity of operation during use and improves the convenience of use
No free acid design: The battery structure design avoids the presence of free acids and reduces the risk of battery liquid leakage
Low self discharge rate: The monthly capacity loss is less than 3%, and even long-term storage can maintain sufficient power reserves to respond to emergencies at any time
Multi directional installation: Batteries can be installed in multiple directions according to demand, adapting to various device structures and providing greater flexibility
Ultra low internal resistance: The internal resistance of the battery is as low as 2.7m Ω, ensuring fast response and stable output under high power demand
Long life design: Under the application of float charging, the battery life can reach 10 years, greatly reducing the frequency of replacement and saving overall operating costs
Fire extinguisher installation: Built in flame retardant materials further enhance the safety of the equipment during use, especially suitable for scenarios with extremely high safety requirements
AGM technology: The absorbing glass fiber pad effectively absorbs gases inside the battery and undergoes gas recombination, reducing gas emissions and extending the battery's service lifeProduct Application ScenariosMPL155-12-BB battery  ies are widely used in multiple industries, especially for equipment and systems that require high reliability and long-term backup power:Uninterruptible Power Supply (UPS):  Ensure stable power supply for important equipment during power outages to avoid data loss and equipment damage
