I called the Apple support about my MacBook Pro that is over 5 years old informing them I needed a battery. I provided the S/N and informed them it's an early 2011. They made an appointment me to visit an Apple Store The Apple Store looked at my MBP and informed me it was over 5 years old and was considered obsolete. They could not service it or sell me a battery b/c it was over 5 years old......REALLY! When I called it in they knew it was over 5 years old....At that point how about telling me it was considered obsolete and they will not service it!!! The bottom line is the Apple support wasted my time and I should have just gone online to purchase the battery!
