Get additional battery life with this high capacity Lenovo ThinkPad T440 and T440s battery.
The ThinkPad T440s battery has twice as many cells as the original 3 cell Lenovo battery. This battery is thicker than the 3 cell battery and it will protrude to the bottom of your laptop about an inch. However, that added capacity provides terrific battery run time.
This ThinkPad T440s Battery uses the highest quality lithium-ion cells and battery components that run longer, charge faster, and weigh less than cheaper, lower quality batteries. Lower quality batteries are made with inferior cells and parts that can wear out in as little as 6 months.
Li-ion batteries are not subject to the memory effect common with older battery technology. This laptop battery replacement is 100% compatible with the original battery specifications and is individually tested and backed by a 2 year warranty.
