The Compaq Evo N410c features two extra batteries. If you do even a modest amount of traveling, we recommend getting a second battery. They range from $100 to $300, and they are worth the money. Many notebooks allow you to swap them into the main media bay. Other secondary batteries clip on to the back of the notebook or attach via a cable. Next time you're trapped on the tarmac, working away on your laptop, and your primary battery is about to die, you'll thank us for encouraging you to buy that second cell. If you rarely travel with your notebook, however, and your laptop is pretty much always plugged in, don't bother with a second battery
