How to Maximize your Laptop Battery Life

Batteries last considerably longer when you maintain them accordingly 


Most modern laptops use lithium-ion batteries, the same as in many smaller consumer    devices like watches and flashlights. These batteries can be charged hundreds of times    without affecting the battery life. 

Older laptops use nickel-cadmium and nickel metal hydride batteries. These batteries      require more maintenance than lithium-ion batteries. NiCad and NiMH batteries must be fully  discharged and then fully recharged once a month for optimal battery life. 

Here's how to maximize your battery:

• Charge a new laptop computer for at least 24 hours before using it.
• Remove the battery if you use the laptop plugged into the wall most of the time.
• Lithium-ion batteries last the longest if they stay between 20 and 80 percent charged.
• Occasionally charge the battery during lengthy storage times.
• If you won't be using the laptop for a month or more, remove the battery. If you don't have a removable battery, run the charge down to 50 percent before storage. The battery will drain in storage. If it sits uncharged for long, it can be damaged.
• Avoid extremely hot or cold temperatures. Don't leave your laptop in the car on a summer day or during a winter blizzard.
• Adjust the keyboard lighting, sleep settings, and screen brightness downward for better battery life.
