In building fire protection systems, 4V4Ah lead-acid batteries supply emergency power for exit signs, corridor emergency lights and fire flashlights. They switch to power supply instantly once mains power cuts off to guarantee evacuation lighting. Equipped with flame-retardant casing and explosion-proof valves, the batteries adapt to damp environments such as basements and power rooms, requiring no regular maintenance. Widely embedded in fire lights of office buildings, apartments, malls and factories, they enjoy a 3-5 year floating service life and cope with power outages and fire accidents, forming a safe backup power system for buildings.
