We've come a long way from sweat and a screwdriver. A hundred years ago, builders would never have envisioned a tool as powerful and efficient as this one. Heck, even 20 years ago. Science has ushered battery technology along, and the LXT lithium-ion system that powers this impact driver has a ton of advantages over standard NiMH or NiCad batteries. The lithium-ion technology means 1,400 battery life cycles, longer run time, lighter weight, a great reduction in the self-discharge rate and built-in shock-absorbing features to protect your battery. But perhaps the coolest innovation is what Makita calls its 45-minute optimum charger. It actually talks to the batteries it charges throughout the cycle, using a built-in memory chip in the battery and, believe it or not, a CPU chip in the charger itself, which analyzes the data stored in the battery chip to decide on the best charging method at that time. The drill/driver itself is fairly compact and lightweight, weighing in at less than 5
