Fire sprinkler and hydrant water pumps are core fire-fighting equipment, relying on large-capacity deep-cycle lead-acid batteries for emergency power during sudden blackouts. Featuring strong load capacity and stable instantaneous discharge, they adapt to high-power startup load of pumps for factory and high-rise building fire pump rooms. When municipal power fails in severe fires, they support pump startup and water supply to curb initial fire spread. With temperature resistance and impact resistance, they adapt to humid pump room environments. They have long service life, high fault tolerance, lower fire explosion-proof access threshold and better practicability than lithium batteries.
