The 12V 65Ah valve-regulated lead-acid batteries serves as the core backup power source for small and medium-sized communication base stations. Featuring mature technology, maintenance-free operation and high stability, it adapts to power supply scenarios of various outdoor and indoor communication equipment. It works in floating charge energy storage state under normal municipal power supply without manual operation. In case of power outages or line faults, it switches to power supply instantly to sustain base station signal transmission and gateway operation, ensuring uninterrupted network signals. With low internal resistance and self-discharge rate, it adapts to complex environments such as mountainous and suburban areas, effectively avoiding signal paralysis caused by power failure.
