How to Save Battery Life on a Laptop

If you're looking to squeeze some more juice from that laptop battery, these tips will have you tapping the keys just a little bit longer.


  • Step 1: Clean the contacts on the battery with rubbing alcohol every few months. A clean battery contact will increase efficiency and make the power transfer smoother between the battery and the laptop.
  • Step 2: Remove the battery when you don't need it and use the AC adapter instead. This saves the battery from constant charging and decreases the wear and tear, prolonging the life of your battery.
  • FACT: In 2010, researchers at the University of Central Florida were able to increase the capacity of a solid state battery 200 to 300 percent, leading to a breakthrough for electric vehicles.
  • TIP: Use a cooling pad with a fan to keep the battery and laptop cool.
  • Step 3: Keep your laptop and battery cool. Clean the space around the laptop to avoid dust and debris from clogging the cooling fan. Be sure to use the correct voltage AC adapter to charge your battery.
  • TIP: Replace your battery if you notice it running out more quickly, or if you have to charge it more often for the same amount of use time.
  • Step 4: Turn off any unused ports and programs when not in use. Switch the wireless card off when you don't need to be on the internet.
  • Step 5: Set your laptop's power options to turn off the screen and put your computer into hibernation after several minutes of non-use. Dim the screen backlight to conserve energy when you work.
  • Step 6: Invest in a new, high quality lithium-ion battery that hasn't expired. Select something in the middle of your price range and stay away from the least expensive battery, which may contain inferior materials.
