for many years, the chemistry used in power tool batteries was commonly nickel metal hydride (ni-mh) and nickel cadmium (ni-cd). during the past decade there has been an almost universal conversion to lithium-ion (li-ion). there were numerous reasons for the change, such as higher energy density (more energy in a smaller size), lower-toxicity materials, no memory effect, slow rate of self-discharge. the benefits of this newer li-ion technology have allowed higher-demand tools and applications to be battery powered, and provide significantly more work-per-charge. this extended capability, combined with the portability of battery tools, has resulted in a dramatic increase in their use.
