A qualified discharge occurs if the battery discharges from RM ≥ FCC –Near Full * 2 to the EDV2 voltage
threshold with the following conditions:
• No valid charge activity occurs during the discharge period. A valid charge is defined as an input 10 mAh into
the battery.
• No more than 256 mAh of self-discharge and/or light discharge estimation occurs during the discharge
period.
• The temperature does not drop below 5°C during the discharge period.
• The battery voltage reaches the EDV2 threshold during the discharge period and the voltage was less than
the EDV2 threshold minus 256 mV when bq2060 detected EDV2.
• No midrange voltage correction occurs during the discharge period.
FCC cannot be reduced by more than 256 mAh or increased by more than 512 mAh during any single update
cycle. The bq2060 saves the new FCC value to the EEPROM within 4 s of being updated.
