Our take on the DEWALT DCB204 XR 20V MAX 4.0Ah Lithium-Ion Battery

The DeWalt DCB204 is a genuine 20V MAX XR lithium-ion pack rated at 4.0Ah. It fits every DeWalt 20V MAX and XR tool and charger, and its 4.0Ah cells give longer runtime than the compact 2.0Ah packs that ship with many kits. A built-in LED fuel gauge shows charge at a glance, and the pack has no memory effect, so it can be topped up between jobs. It is the middle step in DeWalt's line: more runtime than the 2.0Ah but lighter and cheaper than the 5.0Ah. Owners like the gauge and the fit; the common complaint is that the pack is heavier than compact batteries and that genuine packs are costly compared with third-party ones.
