Hi, we are using the bq27425YZFR-G2A battery fuelgauge. Sometimes we have to swop batteries and in those cases have to reset the State of Health (SoH). So I implemented the RESET (0x0041) in code. What is find is that on some products it resets the SoH but on others the SoH stays the same. All other commands sent to the chip works so I'm very confident that the hardware works. I looked at the chip codes to see if when "working" chip is different from the others that does not reset SoH.
TI 46AXXC1 BQ27425 (SOH doesn't reset)
TI 85C9HV1 BQ27425 (SOH doesn't reset)
TI 34A0XC1 BQ27425 (SOH reset works)
