  • Our take on the DeWALT 20V 4.0 AH Batteries

    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.

    Questions and answers

    Is this the same as the battery in DeWalt 20V MAX kits?
    It is the XR 4.0 Ah pack, which is the larger battery often bundled with premium kits. Standard kits usually ship with 2.0 Ah packs.
    Will it fit all DeWalt 20V MAX tools?
    Yes, it fits the 20V MAX line, including drills, drivers, saws and lights. It does not fit 12V MAX tools or tools that require FlexVolt packs.

    The 5.0 Ah pack gives more runtime but is heavier. The 4.0 Ah pack is lighter and better balanced on hand tools.

    Yes, a 3-LED fuel gauge on the pack shows the state of charge at the press of a button.
    Does it lose charge when stored?
    DeWalt rates it as having virtually no self-discharge and no memory effect, so it holds charge between uses.
