I bought this drill about eight months ago. I was looking for a more compact, light weight drill for cabinetry work. Initially I was pleased with the drill, it is light, compact, and ergonomic. The problem is about 30% to 40% of the time the battery will be dead when it is left in the charger. The green light will be on indicating that it is completely charge, but it is not. It seems to be getting progressively worse. I'm not a novice, and I know proper battery maintenance protocol. I've owned Dewalts, Panasonics and Milwaukees and have never had this problem. In checking the reviews I see that others have this same problem, and apparently Makita batteries are often troublesome. I'll keep using it despite this flaw, but I'll never buy another MakitaPOS again. Why play Russian roulette with your money and hope you get one that is reliable, there are plenty of good quality tools to choose from, By the way, 10 minutes ago I bought a Bosch cordless drill and grinder.
