高率放电叉的作用是测量蓄电池单格两端电压,一般指示电压在1.5V以上的均表示所测单格情况良好。笔者在实践中发现,用高率放电叉测量蓄电池单格两端电压均在1.5V以上,各导线连接良好,空转测试启动机时其运转正常,但是,启动发动机时,却 The role of high rate discharge fork is to measure the voltage across the battery cell, the general indication of voltage above 1.5V are said that the measured cell is in good condition. The author found in practice, with a high rate of discharge cell voltage across the battery cell are above 1.5V, the wire connection is good, idling test starter machine when it runs normally, however, start the engine, but
