bq27200 Capacity gauge

Dear Sir:

       I used bq27200 in my product. My Battery Capacity is 18,000 mAh .

I  checked datasheet ： 6000 mAh is  mamimum of bq27200 .  Can it work with my Battery？

     By the way, for bq27200, Battery Capacity (Min)  is the same as Battery Capacity (Max) , Why?.

     I wish someone help me,

Howard
