How to Care for a Lithium Ion Battery for a PC Notebook Most laptop computers now run on lithium batteries. This is because lithium batteries hold charges longer and can provide continuous power longer. However, to ensure that a battery holds its peak performance you need to take special care of it. You can do this without any special tools or programs. Shut down the notebook computer when you are not using it. Leaving the laptop computer on at all times is going to shorten the overall life of the battery. Allow the battery to run all the way down before performing a charge. If your lithium ion battery becomes accustomed to charging when the battery is only half full it will start to forgo using the second half of the battery, shrinking the charge time of your battery. Keep the laptop and the lithium ion battery out of extreme heat and cold. This can wreak havoc on the battery and cause it to malfunction. Using the laptop battery in the cold can also quickly reduce the charge. Power down the computer when the battery begins to overheat. This typically occurs while watching DVD movies and playing video games. Overheating the lithium ion battery can permanently damage it.
