Laptops were created for more flexibility, for setting us free from sitting to a desk in order to surf the net or watch an online movie. But, can we enjoy this if a laptop's life is only 2 hours, once unplugged?

Still, there are laptops that have long-lasting battery life and we revealed the top 10 of them.

They were tested with continuous web surfing over Wi-Fi and they all last at least 7 hours. Of course, some retailers offer sold-separately batteries for increasing your laptop's life.



Lenovo ThinkPad X230 (20:46 with 9-Cell & Sheet Batteries)

Consider Lenovo ThinkPad X230 a laptop from future that comes with optional batteries.

This laptop is available in the usual variant with a 6-cell battery that lasts 7 decent hours, but is also available with 9-cell battery that will add 3 hours of life. If this is still not enough for you, this laptop also works with a sheet-battery that, when paired with the 9-cell, helps your laptop working for 20 epic hours!


           


Lenovo ThinkPad T430 (13:25 with 9-Cel Battery)

As the other ThinkPad, this one comes with the two variants:

6-cell battery or 9-cell. For an extra of 50$, the 9-cell battery will help your laptop work the all-day long and maybe some: 13 hours and 25 minutes.


Dell Latitude E6430 (10:37)

This is a very solid choice.

It has Tri-Metal frame (made of magnesium alloy, steel hinges and chrome bumpers), spill-resistant keyboard and resistance to degrees, dust and drops, not to mention that its battery lasts 10 hours and 37 minutes. Of course, the 9-cell battery that makes it possible costs an extra 79$.


Sony VAIO SE (10:35 with sheet battery)

The sheet battery means an extra 150$ to the 929$ starting price, but with this money you can get a laptop that stays up to 10 hours and 37 minutes.

The battery sheet will help you watching movies on that 1920x1080 matte display, without plugging it into a power outlet.


Dell XPS 14 (8:17)

This Ultrabook is heavier than many other, but don’t be fooled.

It’s true that the 64-watt battery supplies added heft, but it lifted the battery life to 8 hours and 17 minutes.


Apple MacBook Air (8:10)

The apple MacBook Air is getting better and better.

The 2012 model lasts unplugged 8 hours and 10 minutes and it has a faster Intel processor, adds USB 3.0, boats gaming-worthy integrated graphics and costs 100$ less than the previous model.


Apple MacBook Pro with Retina Display (8:02)

The retina Display tallies up to more than 5 million pixels on a 15-inch panel.

What kind of battery can power a screen like that for 8 hours? Apple made it!


Lenovo ThinkPad Carbon X1 (7:45)

This ThinkPad comes with impressive specifications like a fast Core i% CPU, a durable carbon roll cage and a 14-inch matte screen with a 1600x 900 resolution.

Not to mention that for the price of 1,249$ it offers a 7 hours and 45 minutes life battery.


Toshiba Portege R835 (7:35)

Toshiba Portege R835 packs power and performance for any working professional in need of a travel-ready laptop.

For $799, the system ships with Core i5 power, 4GB of RAM, a 640GB hard drive, and a battery that lasted 7 hours and 35 minutes on the LAPTOP Battery Test.


Acer Aspire TimelineU M5-581TG-6666 (7:29)

This 15.6-inch media-minded laptop lasted 7 hours and 29 minutes on a charge, and, for $829, includes a low-voltage Core i5 processor, 6GB of RAM, a 500GB hard drive and Nvidia GT 640M LE graphics that helped it wipe out the competition on our graphics benchmarks.


So, if you are really annoyed about short-lasting battery lives and you are a passionate or you’re earning your living by using a laptop, a long-lasting battery life laptop would be a very good investment.
