摘　　要：采用普通三段式充电和慢脉冲快速充电法对12 V、10 Ah VRLA电池分别进行70%DOD和100%DOD循环测试。慢脉冲快速充电过程中的大电流和去极化作用,使电池的内阻增加缓慢,电池的循环寿命分别比普通三段式充电法的增加了约300次(70%DOD)和170次(100%DOD)。The 70%DOD and 100%DOD cycle tests of 12 V, 10 Ah VRLA battery were done by the ordinary three-stage charge and slow pulse fast charge methods. The large current and depolarization during the slow pulse fast charge slowly increased the internal resistance of battery. The slow pulse fast charge method increased the cycle life of the battery about 300 times （70% DOD） and 170 times （100%DOD） than that of the ordinary three-stage charge method, respectively.
