摘　　要：VRLA电池组中的单块电池和单格电池在放电电压达到终止电压(10.5 V和1.75 V)之前是比较均匀的,它们之间的标准差较小,且很少变化;但当接近终止电压时,均匀性变差。过度深放电给电池板栅和活性物质带来的损害,会劣化VRLA电池组的均匀性,降低电池容量,缩短VRLA电池组的寿命。Before the discharging procedure was proceeded to the terminal voltage （10.5 V and 1.75 V）, the single battery and single cell in the VRLA group were more uniform, the standard difference between them would be smaller and behave less change only. When the discharging procedure was come close to the terminal voltage, the uniformity would be lacking. Over deep discharge would bring some damage to the grids and active material of battery, deteriorate the uniformity of VRLA group, decrease discharge capacity and shorten the service life of VRLA group.
