The defining feature of the bq40370 is the Impedance Track algorithm. Unlike simple voltage-based gauges (which are inaccurate under load) or simple coulomb counters (which drift over time), the bq40370 combines both methods:

New cells require a specific charge/discharge cycle—often with long "relax" periods—to sync with the chip's firmware.
As a lithium-ion battery ages, its internal resistance increases. A standard gauge might show 40% remaining, but under a heavy load (e.g., a power drill or a laptop CPU spike), the voltage might sag below the cutoff threshold, causing a system shutdown. The bq40370 predicts this sag by tracking impedance, providing a Remaining Capacity (RM) reading that remains accurate even under pulsed loads.
