1．蓄电池是UPS设备中造价最贵的元件之一，使用和维护不当时易损坏、所以正确的使用和维护尤为重要。（1）定期（6个月左右）检查UPS电源内电池组中各单个电池的端电压。若单个电池间端电压超过1V以上时就需进行维护（用均衡衡压限流0.5CA充电或更换电池）（2）蓄电池（组）一
1. Battery is one of the most expensive components in UPS equipment. It is very easy to use and maintain when improperly used and maintained. Therefore, proper use and maintenance are especially important. (1) Periodically (about 6 months) Check the terminal voltage of each single battery in the UPS battery pack. If the single cell voltage exceeds 1V above the need for maintenance (with equalization pressure limiting 0.5CA charge or replace the battery) (2) battery (group) a
