What good is a notebook that dies two hours after it’s unplugged from the wall? Not much. We’ve created a list of the clamshells that ran the distance on the LAPTOP Battery Repair – Test (continuous web surfing over Wi-Fi). Each machine lasts (at least) to the 7-hour marker, but some systems use larger, sold-separately batteries to stay active up to 20 hours. See for your yourself below.

Looking for a battery that can make it through the day without having to be tied to a power outlet? Laptop Magazine’s Kenneth Butler has you covered with his rundown of 10 long-lasting laptops.
