Manage your portable Mac computer’s battery
Your portable Mac has a battery so you can use it when an electrical outlet isn’t available. To learn how to charge the battery and maintain battery life, see the topics below. To learn if the battery can be replaced, refer to the documentation that came with your Mac.
Charge your battery by connecting the power adapter to your Mac, then plugging it into an electrical outlet.
Check your battery’s status. The Battery Status menu at the right side of the menu bar shows you how much charge your battery has and whether it’s currently charging.
Conserve your battery’s power by adjusting settings in Energy Saver preferences.
