Never say never. The last time my Early-2004 iBook (bought 3 weeks before the late-2004 model came out😡) was in for repairs, they replaced the logic board, hard drive and... battery! 😎 Maybe they felt sorry for me as it was 400-500 cycles in and could only hold a charge for 20 minutes. The paperwork didn't mention the battery being replaced nor was that the problem it was in for. It wasn't included in any of the recalls either. The only way I found out was it holding a normal charge and only having a few cycles on it. But as others have said, it's not officially covered by AppleCare when it gets old and used.
