The LithiumTech 18V Drill/Driver utilizes the latest battery technology to offer a powerful, durable, all-purpose drill that is also light-weight and easy to manage. 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.
