Not really. They should be fairly low cost and even if you have to replace them in 18 months the cost would still not be much of an issue. It's like a car, as it gets older you might need to replace parts more often.How are local phone repair shop batteries compared to a OEM Apple one? Any disadvantage ?
You can do a mail-in repair to Apple.
The non-OEM batteries don't have the same capacity or internal resistance compared to the original. And you won't be able to read the battery capacity in iOS 11.3 because non-OEM batteries are not supported.
Thanks for letting me know that! I think I may do mail-in repair but hate being without a phone for 9 days.
