摘　　要：阀控式铅酸蓄电池简称VRLA电池,维护量小,在变电站直流系统广泛应用。然而VRLA电池应用中,有许多容易被忽视而有可能导致严重后果的问题,对整组电池放电、过充电的传统方法处理落后电池将损害非落后电池,比较理想的方法是落后电池脱离电池组进行单独放电、充电恢复容量。Valve regulated lead acid （VRLA） battery is applied extensively in substation DC systems as its less maintenance. However there are some problems in VRLA battery application, which are able easily to be ignored and from which the serious aftereffect could be caused. Traditional method, by mains of which whole group battery has to be discharged and then over-charged for recovering the low batteries, could lead the good batteries to be damaged, A more perfect method may be to disassemble the low batteries from the group battery and make discharge/charge separately in order to renew its capacity.
