Battery cycle and degradation data seems to go with the battery itself. On the battery management board there is a controller chip keeping count of these things. Only some models have known reprogramming methods, I’m not sure MacBook Air battery is among one of them.
Battery capacity measurement may be corrected by using it for a few cycles.

Hey Sy
As @danj has mentioned above in his post to your issue, resetting the SMC controller after a battery replacement helps the MacBook detect the new battery. You also can monitor your batteries behavior with the Apple widget on the top of the Menu Bar.
