I am thinking more or less a laptop and I was wondering which be best and how long each last for. Thanks!

Whats the diffrence between a 6-cell and a 12-cell mobile?

the number of cells ... its not necessarily an indicator of freestyle life ... the mah or milliamp hour rating is what to look at ... but if ur chitchat about matching laptop then most expected the 12 is going to have alot better go ..
more lithium ion cells within the 12 cell as compared to the 6 which give your computer a longer battery-operated life.
a 12 cell give you twice amount of power a 6 cell.
The 12 cell should last twice as long on a charge. 3hrs to 6 hrs average. The vivacity will be about duplicate.
