Overview

Meet the DEWALT DCB240, a 20V MAX compact lithium-ion battery with a 4Ah capacity. It packs up to 80 watt-hours of energy, designed to deliver extended runtime while maintaining the same compact footprint as the 3Ah model. This balance of power and portability is useful for users who need to keep a tool close at hand without weighing down the work belt.

In real-world use, you may notice longer run times between charges without increasing the battery's size. The battery's design prioritizes balance, so it stays comfortable in your grip during overhead work, vertical setups, or long sessions on the job site. This helps you maintain control and accuracy as you move through cut, drill, or fastening tasks.

Key advantages

  • 4 Amp Hour (80 Watt hour) capacity provides extended runtime
  • Same Size & Weight as DCB230 20V MAX* Compact 3Ah Battery
  • Lighter weight with same capacity as DCB204 4Ah battery
  • Compatible with 20V MAX* tools and chargers
  • Includes fuel gauge 3-LED charge indicator

What to expect in practice

From a practical standpoint, the compact form factor helps you reach tight spaces and maintain balance when working above shoulder height. The fuel gauge indicator lets you gauge remaining energy at a glance, so you can plan out tool changes without second guessing. The component's rugged build is designed to withstand everyday job-site conditions, helping you rely on power when you need it most.

Usage scenarios

  • Overhead fastening, carpentry, or framing work where weight matters
  • Prolonged use on a single project without frequent battery swaps
  • Stationary or mobile setups where tool balance improves control

Warranty and support: The DCB240 includes a 3-year limited warranty, giving you added confidence alongside DEWALT's legacy of reliability in power tools and accessories. This battery is designed to integrate smoothly with a broad range of DEWALT 20V MAX tools and chargers, helping you build a flexible, capable power system for your workshop or site.
