DeWALT DCB549 18V/54V XR FLEXVOLT 15.0Ah Li-Ion Battery

Extra-high capacity battery for extended runtime and demanding cordless tools

DeWALT DCB549 is a high-capacity XR FLEXVOLT lithium-ion battery designed for professionals who need longer working time from their cordless tools. Its intelligent voltage-switching technology allows it to operate at 18V or 54V, making it a versatile choice for compatible DeWALT XR and XR FLEXVOLT equipment.

Key Benefits

15.0Ah capacity at 18V: Built for longer working sessions, the DCB549 provides substantial battery capacity for demanding applications. It is particularly useful when frequent battery changes would interrupt progress.

Automatic 18V/54V voltage switching: FLEXVOLT technology changes the battery's output voltage according to the compatible tool being used. Fit it to a compatible 18V XR tool for extended runtime, or use it with a 54V XR FLEXVOLT tool to access the higher-voltage platform.

Designed for demanding applications: With 270Wh of energy, this battery is well suited to compatible high-demand tools where sustained cordless power is important.

Built-in battery protection: Integrated protection helps guard against overheating, overload and deep discharge, supporting reliable operation and battery life.

Three-LED charge indicator: Check the remaining charge at the touch of a button, making it easier to decide when to recharge or swap batteries.

Low self-discharge: Lithium-ion technology provides very low self-discharge and no memory effect, helping the battery retain its readiness between uses.
