DC2039A is used to test LT4015.
The 2-cell Li-ion battery is charged from empty, and the charge itself is completed successfully.
However, when I checked the log data after the charge was completed, the value of the coulomb counter had not changed for more than 40 minutes since the start of the charge.
I(BAT) has recorded the value (1A) as set from the start of charging.
Therefore, when the I(BAT) value is totaled, the value is close to the ideal value, but the value of the coulomb counter is far from the ideal value.
Is there a condition for the value of the Coulomb counter to change?
