MacBook Pro Battery Dying

I noticed an "Exclamation Mark" icon and the "Service Battery" words under the battery icon. No wonder recently my battery had not been lasting as long as it used to be. As I never buy Apple Care warranty (and never will), changing the battery should be expensive, but it had been 4 years, so still worth it :)


My desktop Mac dead after 5 years, my MacBook Pro battery dying after 4 years, think quite well used liao :P


I downloaded Coconut Battery and found that my battery capacity is only 66% of the original.
