The DCB204 is DeWalt's 20V MAX XR lithium-ion pack rated at 4.0 Ah, about a third more capacity than the standard 20V MAX packs. It has a 3-LED fuel gauge on the pack, weighs 1.42 lbs, and holds charge with no memory effect and very little self-discharge. It suits owners of DeWalt 20V MAX tools who want longer runtime without moving up to a heavier FlexVolt pack. Against the 2.0 Ah packs it runs tools noticeably longer; against 5.0 Ah and larger packs it is lighter and cheaper in capacity but gives up runtime.
