The 5 Best laptops with the Longest Battery Life

The 5 Best laptops with the Longest Battery Life

 No matter how stacked its specs are, a laptop is useless if it can’t hold a charge. Fortunately, there are plenty of notebooks that go the distance. Using our Laptop Mag Battery Test (continuous Web surfing over Wi-Fi), we’ve identified the 5 longest-lasting notebooks on the market. We’re talking anywhere from 9 hours to more than 20 hours of endurance, which should more than suffice for that cross-country fight, long day of meetings or multiple, back-to-back classes

1. Lenovo ThinkPad X240

The 5 Best laptops with the Longest Battery Life

Lenovo's X200 ThinkPad series is synonymous with portable productivity, and the X240 lets you get more done than ever without rushing to the nearest outlet. This lightweight laptop's built-in battery provides a good 7 hours and 40 minutes of juice, which stretches to a whopping 20 hours and 28 minutes when you upgrade from its 3-cell to its 6-cell battery. This endurance is the most we've ever gotten from a laptop without a sheet battery attached to the bottom, and makes the X240 the perfect productivity companion.

2. Lenovo ThinkPad T440s

The 5 Best laptops with the Longest Battery Life

One of our favorite business notebooks, the Lenovo ThinkPad T440s has the battery life to back up its strong fourth-generation Intel Core performance and vibrant display. This comfy laptop can be configured with a 3-cell battery that lasts an above-average 7 hours, but you should spend the extra $5 for the optional 6-cell battery that more than doubles that life to 14 hours and 36 minutes. The T440s also has an additional 3-cell internal battery, so you can swap out battery packs without your device going dead

3. MacBook Air 13-inch

The 5 Best laptops with the Longest Battery Life

 

The latest MacBook Air keeps the same sleek design as its predecessor and adds a zippier Core i5 processor for $100 less. The best part? You still get awesome battery life. The 13-inch Air lasted a very long 12 hours and 20 minutes on the Laptop Mag battery test. Add in a comfy keyboard and touchpad and easy-to-use OS X Mavericks, and it's easy to see why this $999 Air is our favorite ultraportable value.

4. Acer TravelMate P645

The 5 Best laptops with the Longest Battery Life

 

Acer's TravelMate P645 is an impressive IT powerhouse with the endurance to match. Clocking in at 9 hours and 46 minutes, the sleek P645 outlasted many of its thin-and-light competitors with more than enough juice to get through the workday. The P645 comes loaded with security features, and its staying power gives business users even more peace of mind when working remotely.

5. MacBook Pro 13-inch

The robust MacBook Pro 13-inch with Retina display grew even stronger for 2013, and Apple didn't have to sacrifice battery life for added power. This stylish notebook lasted a noteworthy 9 hours and 31 minutes on our battery test, providing plenty of juice for photo editing, video chatting with friends or spending late nights in the studio with GarageBand.
