Apple care plus
Can I use Apple care plus, at the end of the 2 years, to change the battery that will be worn out? Thanks
iPad Air, iPadOS 14

If the Apple Care+ is still active at that point, and the battery health is at less than 80%, then yes, Apple will replace the battery for free.
Otherwise, you will have to pay for it, but the battery replacements are not very expensive.
