Why This Tool Is Worth It

In any shop, the biggest bottleneck is often power management. Standard 1.5Ah or 2.0Ah batteries are fine for light drilling, but they fail quickly when used with high demand tools like circular saws, grinders, or impact wrenches. These 4Ah batteries provide the extra fuel needed to finish a project without constant trips to the charger.

The build quality of the DCB240 model ensures these packs can handle the vibration and drops that occur on a busy jobsite. With the integrated LED fuel gauge, you will never be caught off guard by a dead battery in the middle of a critical cut. At this price point, you are essentially paying less than $40 per battery, which is an incredible value for genuine DEWALT lithium ion technology.
