How to Replace Internal Batteries for Cordless Drills

With a cordless drill, you can drill a hole through materials with the same efficiency that corded drills offer. The only difference is that cordless drills use the power generated by an internal battery instead of the electrical power flowing through a cord plugged into an outlet. Most types of drills come in both cordless and corded models. Be sure to keep the battery recharged so that you don't have to waste time doing it when you need to be using the drill.
