These smaller batteries only fit on tools labeled as 12v MAX, and vice versa. 20v MAX and Flexvolt batteries are not only too powerful, but they are physically too large for the receptacles on these pint-sized devices.

If tool tracking, inventory, and tool control top your list, Milwaukee handily wins this area, though DeWalt continues to improve. When comparing DeWalt brushless vs Milwaukee brushless tools, both employ smart electronics to better control the speed and power of their tools while cutting, drilling, driving, or sawing.

DEWALT 20V MAX is the next line after 18V, introducing lithium-ion batteries. DEWALT 20V XR improved on the 20V MAX line by introducing brushless motors and high-capacity lithium-ion batteries. DEWALT 20V ATOMIC are designed to be compact and powerful for a wide range of applications.
