Our take on the DEWALT DCB206 Battery 20V MAX 6 Ah Lithium Ion

The DeWalt DCB206 is a 6 Ah lithium-ion pack for the 20V MAX system. It stores 120 Wh, weighs 2.25 lbs and has a built-in LED state-of-charge gauge. It fits DeWalt 20V MAX tools and chargers, so it is a drop-in upgrade for anyone already on that platform. Against DeWalt's compact 2 Ah and 4 Ah packs it trades extra weight for longer runtime; against the larger FlexVolt packs it stays lighter and cheaper to own. Rated 3.2 out of 5 from 14 ratings, reception is mixed, with runtime praised and a share of buyers reporting packs that failed early.
