Bought this in Oct 2016 and has 85 cycles and I just noticed that it is not sitting properly on the desk. It is wobbly and when I look on the reverse I could tell the battery might be swollen. I do not have Applecare and what are the chances that apple would replace it without charging? I looked at the procedure to replace it and seems very time intensive and almost 60+ steps per, iFixit. I could do it, but wanted to see if anyone replaced it?
