Will connecting an external monitor to a new Macbook Pro wreck the battery life?

I currently have an old (mid-2007) Macbook Pro which I plan to upgrade to the new 15" model sometime very soon. I am currently using an external monitor with my laptop in clamshell mode. Even though the monitor has it's own power plug, the laptop will not stay on in clamshell mode under battery power, so in order to preserve what little battery life I have left, I usually just take the battery out and run the laptop directly from the AC cord.
So the new MBPs have this (even more expensive) installed battery. I can't find any good information online about whether
a) the new laptops will run an external monitor in clamshell mode from battery power -or-
b) keeping the laptop plugged in all the time will wear out the battery faster.
I do sometimes take the laptop out and about and run it off of the battery, but it is my primary computer, so most of the time I use it at home, and the external monitor is better for me ergonomically (plus it's a bigger screen).
Despite having always religiously followed Apple's advice regarding battery usage and preservation, they never seem to last as long as Apple says (*shakes fist at Steve*). So before I plunk down $2000 on a new laptop, does anybody have any advice re: battery life in the new models and external monitors?
