Is the notebook power management Settings, set to a few percent below the start of charging, and then halfway off the power, it does not charge. The MAC's power management is 95% unmodified. Most notebook batteries now use lithium-ion batteries, and Apple's laptop is no exception.
With a little attention, you can make your battery to maximize its use time and battery life. Lithium battery appliances will automatically stop charging after the battery is full, and there is no so-called \"trickle\" charging that lasts for more than 10 hours.
After leaving unused for a long time, or frequently charging and discharging for a period of time, the method is a complete charge and discharge, after which the battery can be charged and discharged, and only after a long time of use need to be fully charged and discharged again.

Notebook battery maintenance methods
In daily use, keep the contact points at both ends of the laptop battery and the inside of the battery cover clean, if the laptop battery surface is dirty, gently wipe with a soft, clean dry cloth, so as to avoid power loss. If you do not want to use the battery or the notebook for a long time, you must remove the battery from the notebook, discharge it completely, and store it in a dry, cool environment.
In addition, try to avoid storing the battery with general metal items (especially magnetic objects) to avoid the battery being oxidized by metal or electromagnetic interference. Use the photobattery periodically to ensure full charging. If you need to completely use the electricity in the photovoltaic battery, the specific approach is:
In the Power Management dialog box, select the Battery Drain specific power mode and set all three of its Running on Batteries options to Never so that the laptop is running continuously.
Select this mode, then go to the Alarms TAB and uncheck the Low Battery and Critical Battery warning checkboxes (so that the machine does not go into pause when the battery is low).
Next, let the computer run a lot of CPU time tasks, such as the computer automatically run some computationally complex 3D presentation program, so that the battery will quickly use up the remaining power, of course, do not forget to unplug the AC power when doing this.
