Initial
Impedance
Using a AC 1KHZ meter whose precision must be
less than 0.5%, detect the resistance between the
battery’s positive and negative terminals. The
result value can not include any external
conductor’s resistance. The maximum and the
minimum need to be recorded.
使用 AC 1KHz 检测方法及准确度不低于 0.5 级的仪表，
测量电池接口处正负极之间的内阻值，若检测仪表在检测
过程中使用附加的电池固定夹具和引线，可以视情况减去
固定引线的电阻值，且记录最大与最小之差值。
The internal
resistance≤100mΩ
电池内阻值小于或等于
100mΩ。
