: Many bq40370-based batteries feature a D6SA3-12 thermal fuse . If the battery is electrically "dead" but the cells have voltage, check if this fuse has blown; replacing it can often restore functionality. Traditional fuel gauges use CEDV (Compensated End of

Traditional fuel gauges use CEDV (Compensated End of Discharge Voltage) algorithms, which measure voltage and current but struggle with accuracy under dynamic loads. The bq40370 utilizes Generation 2 Impedance Track. This means it does not just measure voltage; it measures the internal impedance (resistance) of the battery cells in real-time. check if this fuse has blown
