Your laptop batteries would expire in 10 to 20 minutes...

The single most power-draining component in a laptop is the screen (other than the optical drive motor) which is why laptops default to lower the brightness when running on battery power.

Running TWO screens from the laptop's battery pack would deliver half the running time if you were lucky - if it worked at all, since the current draw would be excessive for the battery format.
