Problem in reading capacity

Hi, 

We are using bq27200 with Samsung 2500mAh Battery for our Custom board. 

I am able to read battery capacity and other parameters.

But Help me on how to calculate battery capacity once after resetting bq27200 module(after reconnecting Battery).

Its Showing Capacity = 0;
