Hi all, I just changed a new battery for the macbookpro 2015 early. I found that the new one can’t fit the slot very well, for the bottom frame in the middle. It’s a little narrower than the gap, so I can’t fit it in. Do you have any idea on how to figure out? Thanks. In the following image, the top one is the original battery, and bottom is the new one. Note other parts aligned, but the right point not.
Sounds like you got the wrong battery or a bad copy. Where did you get the battery? If you can take a picture of both your original battery and your replacement side by side so we can see what is different.
