Must a ups battery need to be maintained?

In an uninterruptible power system (ups), the battery can be said to be the backbone of the system, otherwise, ups is only a constant voltage and constant frequency power (CVCF). Ups can supply power that because of ups battery. When the mains abnormal, the inverter directly convey the ups battery’s chemical energy into AC power, the electrical equipment run continuously.

At present, maintenance free sealed lead-acid batteries use in small and medium ups power supply, over 50% of the total cost of ups power supply. Data shows, UPS’s production technology is relatively mature, so about 50% of the ups power failure relate to ups battery. In china, electric power supply grows maturing, especially in city, rare phenomenon of long time power outage, and many important departments adopt dual power supply and diesel generators to ensure electric power, which makes people relax on the ups battery routine maintenance. Most of ups batteries usual lack of effective maintenance, and don’t know the battery’s heath status, resulting in can’t work as designed delay once a long time power outage. On the other hand, the user’s load is constantly increasing, more and more concentrated power density, which the load of ups also corresponding increase. The issue of battery delay is not enough more prominent.

Ups battery failure mainly as voltage is insufficient, insufficient capacity or instantaneous discharge current is satisfied with a set start. Uninterrupted power system in the process, people often one-side that batteries are maintenance free and not take this seriously. Thus, strengthening of the ups battery use and maintenance to extend the battery lifespan and reduce the ups system failure rate has become increasingly important.
