I have been limping my late 2013 rMBP along for awhile with a bad battery. Recently, it started becoming unstable and crashing randomly. I thought that the battery had finally crossed the line so, I replaced it with the iFixit kit. Now it crashes within minutes and the apple diagnosis claims the battery needs repair. any ideas? coconutBattery
