Answer to: Upgrade battery on 13' MacBook ProThat's a used battery from ifixit? And they do not give any mAh or Wh at all? Just that it is fully tested? And that for $119.5? I have to admit: I do have little confidence here. What are the real specs of an original A1322? Apple says 63.5 Wh. This would be 10.8 V and 5880 mAh. Or 5770 mA and 11.0 V. I do see many third party offers, naming about 60 Wh, 10.95 V, ergo 5480 mAh. Steve J. claimed superior quality for their current, not user-replaceable batteries (does not apply for ifixit-readers). Are those 3rd party replacements a real match?
