I have a cMBP 13" mid 2012, 470 cycles count and max capacity drop to 65% from design capacity. On battery power can only last from 1.5 to 2 hours on normal usage, Safari with about 6 tabs (no flash) and spotify streaming, the battery drain quite fast. Battery status shown Service battery but try few times of deplete battery it's the same still. If now is the time to replace I would just order from eBay or local seller, could be OEM. Order from ifixit or OWC the shipping can cost me a bomb to my country. I'm in the urge of upgrading existing 120GB OWC Ssd to 250Gb Samsung Evo 850. But not sure should I go first, battery or SSD?
