No matter how muscular your laptop may be, it’s just an expensive paperweight when it runs out of juice. Lenovo’s Thinkpad X220 has enough stamina to last longer than you can. For just $30 more than the base price, this 12-inch ultraportable’s optional nine-cell battery ran for 12 hours on the LAPTOP Battery Test (continuous web surfing over Wi-Fi). But this notebook was just getting started.
When we combined the nine-cell battery with the X220’s optional six-cell battery slice, we clocked a jaw-dropping runtime of 20 hours and 18 minutes. Granted, this accessory costs a steep $229 and increases the weight to 5.1 pounds, but it’s hard to put a price on epic endurance. Those who seek a machine that can go the distance need look no further.
Starting at $899 ($1,156 with nine-cell and slice batteries); www.lenovo.com
