Resetting the BQ40370 often requires removing a fuse or managing specific "Charge FET" activation commands like DELL_CHARGE which are only valid for short windows (e.g., 30 seconds). Batteries may stop charging/discharging if they detect a

Batteries may stop charging/discharging if they detect a "Permanent Failure" (PF) flag.

Schematic notes:

Failure to perform this learning cycle results in inaccurate battery percentage reporting (e.g., the device shutting down while reporting 20% battery remaining).
