Hey Ashok,

Can you send me the datasheet for the battery you are using, so I can verify all the settings in the gg file.

During the test, I noticed that the RDIS bit gets set during discharge which will disable Ra table updates and is caused by having the wrong ChemID programmed on the gauge. How did you obtain the ChemID you are currently using? Did you use the GPCCHEM tool?

Regards,

Hello Ashok,

I would recommend using the GPCCHEM tool to get a match for the ChemID. https://www.ti.com/tool/GPCCHEM
