Generations are changing and now most users when purchasing a new drill go cordless. In the last few years Lithium Iron (Li-iron) batteries have been introduced into the world of powertools giving excessive amounts of work time meaning batteries don't have to be charged as often. There are other types of battery drills available, these include: Ni-Cad and Ni-MH. These types of batteries were released before the Li-iron so as you can respect they don't hold their charge as long or as well. We stock a very large selection of cordless drills from Makita and DeWalt.
