MacBook batteries require a process called calibration to restore and charge the lithium-ion battery inside. All batteries eventually need replacing. Provided your MacBook battery indicator doesn’t tell you the battery needs to be replaced immediately, calibration can help you get the most out of your battery. Small business owners that use Macbooks on-the-go need to ensure that the computer lasts as long as possible. Recharging isn’t always possible if you’re conducting business on the go, so making sure your battery holds the greatest charge possible ensures your business can continue uninterrupted, even without an external power source.
Click on the battery icon in the top right portion of the screen. The battery should state “Normal” when functioning correctly. If the battery states “Replace Soon,” “Replace Now” or “Service Battery,” then take the battery in to the local Apple Store for replacement or repair.
Plug the power adapter into the MacBook and charge the computer until the green light on the cord turns green, or the power indicator on the taskbar shows a battery charge of 100 percent.
Keep the MacBook plugged in and running for two hours after the charge has completed.
Select the Apple icon from the top left corner of the screen. Click “System Preferences” then “Energy Saver.” Set the “Sleep” slider so that it indicates “Never” under the sleep setting.
Disconnect the power adapter from the MacBook. Let the computer completely run down and turn off by itself. You may use your MacBook during this time. Shut down all applications before the battery dies to ensure that you don’t lose any data.
Turn off the MacBook by holding down the “Power” button for 10 seconds after the battery has died. Leave it off for at least five hours.
Reconnect the charger to your MacBook and start your computer. Keep the computer charging until the green light comes on, or the battery indicator shows a battery charge of 100 percent.
MacBooks that have a built-in battery do not require calibration to restore or charge it properly.
Charge a MacBook by plugging the three-pronged adapter into a wall socket and attaching the magnetic charging block to the charging port on the back left side of the MacBook.
