充電電流200mA設定で、温度0~10°Cの電流が仕様書では20%=40mA

と記載がありますが、実測では100mAでした。

これは正しい動作でしょうか。

充電電流を大きくすれば正常動作するのでしょうか。

    With a charging current setting of 200mA, the current at a temperature of 0 to 10°C is 20% = 40mA in the specifications.

    Although there is a description, it was 100mA in the actual measurement.

    Is this correct behavior?

    Will it work normally if I increase the charging current?

    Hi Hiroshi,

    For ICHG resistors above 65kohm typical, the termination current is clamped to 63 mA typical.  The accuracy at ICHG=500mA is 

    I would expire slightly worse accuracy at lower charge current so 100mA is not unexpected.
