The average thin-and-light notebook lasts about four hours on a charge. That kind of battery life is fine if you’re flying from New York to Orlando or if you’ll be in meetings only half the day. But what if you’re going from New York to San Francisco and you want to use your laptop to check e-mail, and catch the latest episode of House online in the airport, watch a DVD in the air, and maybe even look up some restaurant reviews on your way to the hotel using your broadband card? Or maybe you just want to be able to stay productive at an all-day conference without having to fight over an outlet. That’s where these long-distance runners come in.
When properly equipped, the latest power-sipping notebooks can last a full workday or longer on a single charge. We put several to the test with the LAPTOP Battery Test, which entails continuous Web surfing over Wi-Fi, and found four favorites that last more than 8 hours—more than enough endurance to last a cross-country trip. To achieve these marathon times, though, the systems were equipped with slower processors, premium features such as solid state drives, and extended batteries—which significantly increased both their cost and weight. Still, if you’re looking for the ultimate in endurance, these machines are worth the premium.
