Yes, AppleCare covers MacBook Pro battery replacements if its capacity has fallen below 80% of its original capacity. AppleCare Plus extends the standard warranty of the MacBook and provides additional coverage for up to two incidents of accidental damage. However, AppleCare Plus does not cover regular wear and tear or battery depletion due to regular use. If you're looking for long-term peace of mind, AppleCare Plus is a good option to consider.
