The Necessity And Suggestion Of UPS Battery Maintenance(1)
With market demand, UPS has been widely used in various industries, and batteries have become the power supply guarantee for uninterrupted power supply systems. A UPS without a battery can only be called a stable frequency power supply. When the utility power source is abnormal, the battery converts chemical energy into electric energy, and the inverter converts the AC power source into a load through the inverter, thereby ensuring the uninterrupted continuous operation of the load. Valve-regulated, maintenance-free sealed lead-acid batteries are widely used in large, medium and small UPS, accounting for 1/4 ~ 1/2 of the total cost of UPS. According to the survey, the life of a battery in normal use is generally about 5 years, and about 50% of UPS failures at the end of use are related to the battery. Battery failure is mainly manifested as the single battery backward or low battery floating voltage, short backup time (insufficient capacity), and the UPS that needs battery startu...
