摘　　要：对VRLA电池用不同的充电方法进行充电,做深循环寿命试验,并对实验结果进行分析,总结各种充电制度对深循环VRLA电池寿命的影响。结果表明:1、充电制度对深循环VRLA电池的寿命有着重要的影响;2、恒压(限流)充电方法容易导致电池长期充电不足,从而发生硫酸盐化;3、恒流充电的电池失效原因是正极板铅膏发生软化、脱落;4、脉冲充电的方法可使深循环VRLA电池寿命提高。The deep cycle life experiments were made by using different charging methods, the results of experiments were analyzed, and the effects on deep cycling VRLA batteries were summarized. The results showed that： （ Ⅰ ） the charging method had significant influence on deep cycling VRLA batteries; （ Ⅱ ）the constant-voltage （restrict current） charging method tended to long-term undercharge the batteries; （Ⅲ）the failure cause of constant-current charging batteries was that the active material would be soften and shed; （Ⅳ） the VRLA battery＇s serveice life would be improved by using pulse-charging method.
