Wait, it is possible to get a genuine* battery replacement for an Apple device? And no, I'm not being sarcastic, my friend was told by an Apple Store that even an attempt to open the Macbook chassis voids warranty. They refused to replace the battery EVEN WHEN HE WAS READY TO PAY "because there was an unauthorized attempt to open the device". He finally had to go to a repair shop and get it done under an hour (because now the warranty was void anyway).
genuine = guaranteed by Apple to not break your warranty
If it walks like a duck, quacks like a duck, and looks like a duck...well who cares if it calls itself a swan.
Anyone paying $400 for battery is out of their minds. My $100 apparently ‘fake’ battery performs identical as the one Apple sells. Who cares at that point.
