Dell Xps M1530 Battery Life

Dell XPS M1530 display?

I'm set on buying this laptop (no need to try and sway me away from it), but I'm curious on battery life, if I were to upgrade to Full HD resolution (1920 x 1200). Now, I'm no hardware guru or anything, but would have this screen updated greatly affect battery life? I'm upgrading to the 9-cell battery, however, but should be decreasing the resolution or if it makes much difference. Thanks in advance.

Sorry, I do not have an answer for you, but the 9-cell battery detachable? I'm wondering if I should get it, because if not, I think it would be too bulky for everyday use. thanks.
