If you use a MacBook to run your business, you should be aware of the proper way to calibrate your MacBook battery. A properly maintained battery ensures that you get the most out of your battery during extended flights, business meetings and important presentations. When charging your battery on a daily basis, aim to charge the battery before it completely runs down and unplug the charger once it reaches full capacity. Once every two months, you should calibrate your battery so that your computer gets the full potential out of its battery.

Press the "Power" button to start your MacBook if it isn't already on.

Plug the power adapter into your MacBook and wait until the orange light on the side turns green. After the light turns green, keep your computer plugged in for at least two additional hours. You can use your MacBook during this time.

Unplug the power adapter and wait for the MacBook battery to completely run down. You can use the MacBook during this time but save any work and close the programs before your MacBook goes to sleep. Once the MacBook battery has run down completely and your MacBook has gone to sleep or turns off, let it sit unplugged for at least five hours.

Connect your MacBook to the charger and allow it to completely recharge. You can use the computer while it is recharging.


An orange light on the battery indicates that the MacBook is charging. A green light indicates the MacBook battery has fully charged.

To completely drain the battery and avoid putting your MacBook to sleep, click the Apple menu and then "System Preferences." Select Energy Saver and move the Computer Sleep slider to "Never." Check the "Show Battery Status in Menu Bar" to quickly access the Energy Saver preferences in the future.

Use your MacBook between temperatures of 50 to 95 degrees Fahrenheit for the best battery performance.

Close all programs before your MacBook goes to sleep.


When storing your MacBook, run the battery down or charge it up to reach 50 percent of the available battery. This prevents the MacBook from entering a deep discharge state. Fully charged batteries left in storage may lose their ability to hold a full charge.
