Hello
We use a BQ2060A with Lion Battery, we supply the BQ2060A with 5V and we communicate with the HDQ pin. The SMBC and SMBD lines are pulled up.
When a valid discharge occur, the capacity always increase of 512 mAh with no apparent reason. I control charge and discharge with Ampermeter and remaining capacity seems to be OK.
Best regards
