In the building fire emergency system, lead-acid batteries remain mainstream fire energy storage products due to high safety, strong compatibility and low cost. Different from flammable lithium batteries prone to thermal runaway, they feature flame and explosion resistance for extreme fire conditions, powering all types of fire weak-current and power emergency equipment. Updated AGM gel lead-acid batteries optimize low-temperature endurance and anti-leakage performance, fitting outdoor fire cabins and underground closed fire machine rooms. With complete fire industry certifications, high installation compliance and mature recycling systems, they balance fire safety, project cost and environmental protection, becoming preferred long-term fire emergency energy storage power sources.
