Hey guys, I am just wondering whether or not Apple will replace the built-in battery for my 17" MacBook Pro that has Optibay installed inside. I know that voids the warranty and I don't really care (my AppleCare is still valid). It's just that I'm not sure whether Apple will refuse to replace the worn battery for me or not, for a fee (or treat me the same way as they treat other out-of-warranty machines). If not, I will have to think about where to obtain the battery and replace it by myself Does any of you have experience in this? Please let me know! Thanks!
