Replace MacBook Pro battery
The battery is running at 87% and runs out within 30 minutes. "Service recommended" is listed. Do I need to replace it? If so, how and with what? I can't see any way to access the interior.
MacBook Pro 13″, OS X 10.11
Apple recommends the battery be replaced when the remaining capacity get to 80%.
Regardless, if your "fully charged" battery last no more than 30 minutes, your battery is exhausted; the various chemicals have been depleted.
Non Apple batteries are substandard; have Apple replace it.
