Recently I find out what battery on my Macbook Pro Retina 15" Late 2013 started to swollen. Looking for a good replacement battery now. On the first sight looks like Ifixit and OWC (Macsales) selling pretty good replacement batteries. But after checking info about batteries from this suppliers on different Mac related sites i find what people had problems with both of them. As I'm not in the USA it's very important to receive a good battery from vendor, because if i'll receive bad battery warranty replacement could be real pain in the ass. So what your advise? Ifixit or OWC? Or any other good vendor? Thanks for your advises.
