How to fix "service battery"?
The battery on my MacBook Pro has naturally been deteriorating due to age, but recently it has said it's running on service battery. Is there a way I can fix it at home, or do I have to go to an Apple store to fix it?
I don't know if this helps, but according to the app "Battery Health" my computer is 3.8 yrs. old and has gone through 599 battery cycles.
MacBook Pro, OS X Mavericks (10.9.1)
