Got a MacBook Retina 13" 2015 which needs a battery replacement. I ordered a 3rd party battery which was claiming it was an A1582 battery, for the 13" Retina 2015 (since it is difficult to get this in the UK quickly), however the part number on the battery received is A1493, like the old 2013-2014 models (although the outer packaging says it is compatible for 2013/2014/2015 models). My question is, will this work in the 2015 model? Is there any harm in trying? I have tried emailing the seller (Duracell) to check, and they have since removed A1582 from the title on their website, and not responded to me haha.

Tried this, and can confirm it works fine, although the voltage rating and mAh rating is lower than the 2015 battery, which means it won’t last as long. For future reference, if anyone has issues getting the 2015 batteries :)

I have the same problem but reverse, I mean I have the battery for Macbook Pro retina 2015 (A1508) I want to put in Macbook Pro retina 2014 (A1493) which is the correct battery for the system. My question is it is possible???
