BQ27520-G4: CHEM ID match but very different capacity

Part Number: BQ27520-G4

Using the CHEM ID matching tool. It looks like we have an good ChemID match for our battery, but is it okay that the capacity is different? Our battery is a 2000mAh cell and the recommended ID is for a 10000mAh cell?

Best chemical ID : 256          Best chemical ID max. deviation, % : 2.88

Summary of all IDs with max. DOD deviation below 3%             

Chem ID         max DOD error, %     Max R deviation, ratio

256                  2.88                             0.59

Max. deviations for best ID is within recommended range. Chosen best chemical ID is suitable for programming the gauge.
