Learning cycle for BQ27200DRKR to know actual battery capacity

Other Parts Discussed in Thread: BQ27200, AM3352

Hi,

I am using bq27200 battery monitoring chip in my design with AM3352 sitara processor. I am using Li-ion 3.7v 7800mAh  battery. In my use case I want to display current status of the battery that is what percentage of charge is remaining. From the datasheet I came to know that the chip needs learning cycle to know actual capacity of battery.

Question 1:

Can you please provide the procedure for battery monitoring chip's learning cycle ?

Question 2:

When product goes on to production, performing learning cycle is mostly impossible task for let say 100 boards. What to do in this situation ? Is there any alternative solution ?

Thanks and Regards,
