Pros
Questions and answers
- Which battery lasts longer on a single charge?
- The DCB206 6.0Ah, by about 50% over the 4.0Ah. Expect roughly 1.5 times the runtime in the same tool under the same load.
- Is the 6.0Ah worth the extra money?
- Only if you run high-drain tools like grinders or saws. For drills and drivers, two 4.0Ah packs cost less and keep the tool lighter.
- Will both fit my existing DeWalt 20V MAX tools?
- Yes. Both are 20V MAX packs and work with all DeWalt 20V MAX tools and chargers, including the DCB118 fast charger.
- Which is better for overhead work?
- The DCB204 4.0Ah. At 1.42 lbs it is about 0.8 lbs lighter than the 6.0Ah, which matters when drilling overhead or at arm's length.
- Do both have a fuel gauge?
- Yes. Both use a 3-LED fuel gauge to show remaining charge.
- How do the prices compare?
- The 6.0Ah has run $149.00 to $189.00 since November 2, 2026. The 4.0Ah has run $57.00 to $129.99 in the same period.
