4 cell or 6 cell battery in laptop?

I am in the process of buying a low end Dell computer.

I am deciding on a battery.

it comes with the 4 cell lit ion 29 whr battery.

for $45 more I could get a 6 cell lit ion 56 WHR battery.

How long will the 4 cell last and how long will the 6 Cell last?

Go for the 56 whr. It keeps you portable longer. The approximate times should be listed on Dell’s website.
