After battery replaced, saying replace now
I just replaced the battery in my laptop 3 weeks ago, following all instructions for installation and calibration to the letter. Today, when I looked at the battery bar, it's saying "Condition: Replace now". I literally just replaced it, what's going on?
Update (07/30/2018)
I purchased a battery from iFixit that was specified for my laptop: a MacBook Pro 13" Unibody (Mid 2009 to Mid 2012) Replacement Battery / Part Only
Is dit een goede vraag?
