DeWalt DCB546-XJ 18/54V XR 6.0Ah FlexVolt Battery (2 Pack)
The DeWalt DCB546-XJ 18/54V XR 6.0Ah FlexVolt Battery (2 Pack) is a high-performance power solution for professional cordless tools in the batteries and chargers category. Using XR FlexVolt® convertible technology, each pack intelligently switches between 18V and 54V, delivering extended runtime on existing 18V XR tools and corded-level power on heavy-duty 54V equipment. The 6.0Ah capacity at 18V (2.0Ah equivalent at 54V) supports demanding applications such as cutting, drilling, grinding, and landscaping with fewer battery changes throughout the day. Built-in electronic protection guards against overheating, overload, and deep discharge, while the integrated LED fuel gauge and low self-discharge design help you manage charge levels efficiently on site. Supplied as a twin pack, the DeWalt DCB546-XJ batteries are fully compatible with all DeWalt 18V XR and 54V XR FlexVolt tools and can be charged with standard XR chargers for a seamless upgrade to higher power.
