DeWalt DCB549-XJ XR FlexVolt 18V/54V 15.0Ah Battery
The new 54 Volt XR Flexvolt batteries from Dewalt offer power for the heaviest applications. The innovative LiIon batteries are backwards compatible and can also be used in most machines from the 18 Volt XR range. Very high battery power of 270 Wh and therefore ideally suited for extremely heavy applications over long periods. No memory effect and minimal self-discharge thanks to the latest LiIon technology. With extremely long runtime due to 15 Ah battery capacity (with 18 volt circuit). Optimally suited for tough construction site use due to robust housing and shock-proof soldered battery cells. Easy transport of the battery thanks to mechanical separation of the cell levels, which means that the watt-hour capacity of the battery is below the 100 Wh required for hazardous goods class 9. Charge status display with 3 LEDs (at the touch of a button). Suitable for all DeWalt XR battery machines with 54 and 18 volts (except ToughRadio).

The product meets my expectations.
Bought this for a graco sprayer had to cut the shield underneath but it last a long time might have to invest in a second battery 👍
The Battery is slightly heavier than the 6.0AH But its definitely last longer than the previous. It makes the job done. Less time running up and down, foe a charge. Will be buying more. Recommend 100%
Very happy recommend can order product with confidence Thanks
good quality product compatible 18v flexvolt
