BQ27411-G1: State Of Charge (SOC) value is 100% for every inputs

Part Number: BQ27411-G1
Other Parts Discussed in Thread: BQ27411DRZR-G1B, GPCCHEM

Hi,

I'm using the BQ27411DRZT-G1A battery gauge for one of our projects. I'm getting all the register values like voltage, current etc. But the SOC value I'm getting is 100% for all time. I've used different battery voltages but the register value is 0x64 for all voltage inputs. Is it required to calibrate the IC before we use that? How can I do that?

Please help me to find out what I'm missing.
