I am using the bq27421 gauge with a 1000mAh (typ.) battery. The 1000mAh is the capacity from 4.2V down to 3.0V. My application requires a minimum battery input voltage of 3.5V, so I will be configuring the bq27421 with a TerminateVoltage of 3500mV. That said, when I configure the Design Capacity and DesignEnergy do I need to adjust for the higher terminate voltage? I was told by the battery manufacturer that I can expect 98% capacity from 4.2V to 3.5V, so should I use a design capacity of 980mAh and a design energy of 3,626mWh (3.7 x 980 = 3626)?
