Laptops battery life and Types of Batteries


Laptops have to carry their power supply with them when you take them on the road. They do this in the form of batteries that typically plug into the bottom of the computer. Laptop batteries
come in various types, depending on the notebook manufacturer. The time you can run your laptop
on a charged battery is called the
battery life, and this varies from laptop to laptop. You must charge
your laptop battery on a regular basis.

Battery Life
Batteries provide a certain number of hours of battery life, or operating time. The average laptop battery offers anywhere from
two hours to four hours of battery life. The life of the battery is affected by whether the laptop is being used or is on standby
mode, and by the size of the laptop monitor, with large displays draining power more quickly than smaller ones.

Types of Laptop Batteries
There are several types of laptop batteries, with the most popular type being the lithium ion (Li-ion). Li-ion batteries hold a
charge longer than earlier types such as nickel cadmium (NiCad) or nickel-metal hydride (NiMH). Some laptops also feature
secondary alkaline batteries to power internal clocks or keep the laptop running while the main battery is changed. For best
performance, Li-ion batteries are the standard today.

AC Power
If you use your laptop at home or office rather than on the road, you can plug it into an electrical outlet and run the
computer off electricity all the time.However, laptops used for more than a few hours this way can become overly warm,
which can adversely damage or interfere with your computer’s “health.” To avoid this, invest in a specially made laptop pad to help disperse unwanted heat.
