Security monitoring, alarm and access control systems in communities, parks and shops have extremely high requirements for power supply continuity, and the 12V 65Ah lead-acid batteries is a standard backup power for such security equipment. It automatically stores energy and stands by under normal municipal power supply. In case of sudden power failure, it takes over power supply immediately to ensure continuous monitoring recording, normal operation of infrared alarms, access control recognition and fire alarm devices, avoiding security system paralysis and monitoring blind spots. Featuring stable start-stop discharge and strong environmental adaptability, it supports 24-hour stable operation of security systems.
