Our Verdicts

DEWALT FlexVolt 9.0Ah Battery (DCB609)

The DCB609 is DEWALT's genuine high-capacity FlexVolt pack — built for the cross-platform 20V/60V lineup, at a real premium over standard 20V MAX batteries.

RYOBI ONE+ 18V Fast Charger (PCG004)

A genuine Ryobi ONE+ charger marketed for faster charging than Ryobi's base charger, though stock has been inconsistent — worth grabbing when available if you're staying within the ONE+ ecosystem.
