Portable medical equipment and auxiliary monitoring devices in community clinics and small medical institutions are generally equipped with 12V lead-acid batteries as emergency energy storage power supplies, which are commonly used for medical emergency lights, portable monitors, environmental disinfection equipment and ward monitoring sensors. Medical equipment has strict requirements for power supply stability. These batteries feature stable discharge without voltage fluctuation to avoid abnormal equipment data. They can continuously supply power for basic medical equipment during campus circuit maintenance and sudden power outages to ensure uninterrupted basic diagnosis and treatment work. Safe, stable and low-failure, they fully meet the emergency power supply specifications of primary medical institutions.
