DEWALT 20V MAX* XR® 3-Speed Cordless Oscillating Multi-Tool Kit

Product Overview

The DeWalt DCB240-2 20V MAX 4.0Ah Compact Lithium Ion Battery (2-Pack)* represents a significant upgrade in battery technology. Using advanced 21700 cells, DeWalt has engineered a battery that delivers 4.0 Amp Hours of capacity in a single-row compact housing. This means you get the runtime of a larger “double-stack” battery (like the old DCB204) in a package that is physically the same size as the small 2.0Ah batteries.

What’s Included in the Box

• 2 x DCB240 20V MAX* Compact 4.0Ah Lithium Ion Batteries

• (Note: Charger is NOT included)

• Size-to-Power Ratio: This is arguably the best “power density” battery in the lineup, offering 4Ah capacity without the bulk of the double-stack XR batteries.

• 3-LED Fuel Gauge: Allows immediate feedback on the state of charge.

• No Memory: Can be charged at any time without reducing the total capacity of the battery.

Common Use Cases

These batteries are the perfect choice for all-day overhead work or tight spaces. They are ideal for impact drivers, compact drills, and oscillating tools where you need the runtime of a 4.0Ah battery but cannot afford the extra weight and bulk of the larger XR packs.

*Note: “20V MAX” refers to the maximum initial battery voltage (measured without a workload), which is 20 volts. Nominal voltage is 18 volts.
