    Hello, 

    This is the expected behavior of the gauge, as the gauge does not have flash memory. When the bq27426 is power cycled, it loses the values you have configured to the gauge and reverts to the default values. In order to save the values you have programmed, you will need to save the values on an MCU, then whenever the gauge is power cycled (indicated by the ITPOR bit) you will need to have the MCU reprogram these values onto the gauge. 

    Regards,
