iPad Air 4 电池更换

This article seems to imply that the battery is paired to the IPad, and that the battery health tool won't work. I have an early IPad Air 4 updated to the latest iOS version. The only issue I'm having is that the battery is showing it's age, and is acting up some. If I replace the battery successfully, will there be any impact on the functionality of the iPad? Will it act as though it has a legitimate battery, or will it constantly nag me that I'm not using the original Apple part?
