The LithiumTech 18V Impact Driver utilizes the latest battery technology to offer a powerful, durable Impact driver that is excellent for driving large screws and removing tough bolts. LithiumTech batteries have 3 times the cycle life of ordinary Ni-Cd batteries, and weigh 40% less. LithiumTech batteries have very low discharge rates as well, so they hold their charge over months in storage. LithiumTech batteries never develop a memory effect, so they can be charged anytime, whether fully discharged or not.
