Hi Sir

1. How to adjust parameters which Gauge detect precision
The BQ40Z50-R2 Gauge detected 6700mAh battery, but we found the gauge feedback value over 6700mAh.
Attached is summary graph that gauge detect value drift vary large situation.

2. How to adjust parameters which Temperature characteristics
We set chem ID=2107. Attached is summary graph in different temperature. Have some methods to reduce drift situation?

3. Current consumption problem
The datasheet is shown Typ.= 75uA, but there are not shown max value. Our current consumption is 100-110uA. We can not differentiate
this correct or not.

Your suggestions are appreciated.

Regards,

Mike
