Questions and answers
- Which battery lasts longer on one charge?
- The DCB205, at 5Ah versus 4Ah. Expect roughly 25% more runtime per charge from the DCB205 under the same load.
- Which has a longer service life?
- The DCB2104 is the safer bet. Its tabless cell design is built for more charge cycles, and it carries a 3-year limited warranty.
- Which is better for a grinder or circular saw?
- The DCB2104. DeWalt rates it at 50% more power than the DCB240, which helps in high-draw tools. The DCB205 still wins on runtime.
- Do both fit my DeWalt 20V MAX tools?
- Yes. Both are 20V MAX packs and work with the same tools and chargers, including the DCB1104 4-amp charger.
- Is the DCB2104 worth the extra money?
- At $51.99 on October 29, 2026 it was cheaper than its own $63.70 high on November 2, 2026. If you want the newer cells and the warranty, yes; if you only want runtime, the 5Ah pack does that better.
- How fast do they charge?
- The DCB205 charges in about 30 minutes on a 4-amp charger. DeWalt does not publish a charge time for the DCB2104.
