摘　　要：采用不同的方法对不同型式的铅蓄电池内阻测试结果表明 :荷电态高于 50 %的密封铅蓄电池 ,其内阻或电导值基本不变 ,只是在 50 %以下时才会迅速下降。对多组密封铅蓄电池统计数据证实 :失效前的铅蓄电池容量和电导之间并不存在相关关系 。The experimental results of internal resistance or impedance for different types of lead acid battery by means of different methods showed that the conductance of VRLA battery remained unchanged when the DOD(depth of discharge)was below 50%.As the DOD raised to higher than 50%,the conductance decreased evidently.The statistical data for many groups of VRLA battery demonstrated that no close relationship between conductance and capacity of VRLA battery existed,so it was improper to use conductance value to represent the capacity of VRLA battery.
