DCB205 vs DCB204 — Which Should You Buy?
The DCB205 (5.0 Ah) offers 25% more runtime than the DCB204 (4.0 Ah) and is only marginally heavier (585g vs 510g). For most users the DCB205 is the better value — it is the most commonly included battery in DeWalt combo kits for good reason. The DCB204 suits applications where tool weight matters most, such as working overhead with a drill for extended periods.
