The dual-voltage FlexVolt 20V and 60V Max 9.0 Ah battery automatically changes voltage when we change tools, providing up to 6X runtime (with DCB609 FlexVolt battery when used with DeWalt 20V Max tools compared to DCB201 1.5 Ah battery pack.) in 20V Max tools and the power of corded in 60V Max and 120V Max tools. Take on tough jobs with this battery because patented technology and large format cells mean it runs cooler than the leading competitor 9.0 Ah battery pack for better efficiency under a constant discharge. This is the battery for FlexVolt power and long runtime.
