When it comes to battery life, Acer's TravelMate 8481T is the laptop to beat. It's not all that surprising when you see the battery protruding from the back of the chassis, practically doubling the breadth of the machine. But, if you need to pack the TravelMate away, simply unclip the battery and it shrinks from 41mm thick to only 24mm. Our battery benchmark test – supplemented with looped high-def video – took 326 minutes to run down the TravelMate, so we'd expect that this machine would get you through a mains-free eight hour day with standard use.
