iFixit Replacement battery dead on arrival?
Ordered a replacement battery/self replace kit for late 2012 macbook pro retina, after installation (fiddly but not to bad) new battery seems stuck 69/70% full (went from 69% to 70% after 5 hours of charging) and laptop will not stay on without mains power. Is new battery dead on arrival? I've tried reseting the SMC, no change.
Any suggestions?
Thanks.
Is this a good question?
