Communication base stations require extremely high power supply stability, and the 12V150Ah lead-acid batteries is the core backup energy storage device. It maintains floating charge energy storage under normal mains power and instantly switches to power supply during grid outages or fluctuations to ensure uninterrupted operation of 5G base stations and computer room equipment. With low internal resistance and stable discharge performance, it adapts to steady voltage power demand and frequent charge-discharge cycles. It requires no on-duty personnel, fits the unattended operation mode of base stations, and features long service life and high safety, effectively avoiding communication interruptions.
