Dual-voltage for ultimate flexibility 180 watt hours of energy in each battery pack. Get 360 watt hours when using (2) FLEXVOLT 9.0 Ah batteries in 120V MAX* tools 6X runtime** when used in a 20V MAX* tools The dual-voltage FLEXVOLT 20V/60V MAX* 9.0 Ah battery automatically changes voltage when you 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 under a constant discharge. This is the battery for FLEXVOLT power and long runtime.
