The DCB204 is DEWALT's 20V MAX* XR 4.0 Ah lithium-ion battery, offering an excellent balance of runtime and weight for professional tradespeople. The XR designation indicates premium cylindrical cell chemistry that delivers consistent power output under load compared to standard 20V MAX compact packs. At 4.0 Ah, it provides more runtime than the DCB203 2.0 Ah pack without the added bulk of the DCB205 5.0 Ah. Features a 3-LED fuel gauge for state-of-charge checking. Compatible with all DEWALT 20V MAX* tools and chargers. Covered by DEWALT's 3-year limited battery warranty.
How does the DCB204 single pack compare to the DCB204-2 2-pack?
The DCB204 is the same 4.0 Ah XR battery sold individually. The DCB204-2 bundles two of the same battery at a lower per-battery price. If you only need one battery to supplement existing packs, the DCB204 is the right choice. If you need continuous workflow with one battery charging while the other runs the tool, the DCB204-2 offers better value.
Is the DCB204 compatible with all DEWALT 20V MAX tools?
Yes. The DCB204 works with the full DEWALT 20V MAX* ecosystem including drills, impact drivers, circular saws, reciprocating saws, and outdoor power equipment. It also works with 20V MAX* ATOMIC and FLEXVOLT tools in 20V mode.
How does the DCB204 differ from the DCB205 5.0 Ah battery?
The DCB204 is slightly lighter and less expensive than the DCB205 while providing a bit less runtime per charge. Many professionals choose the 4.0 Ah as a daily-driver battery for drills and impact drivers, reserving the 5.0 Ah for higher-draw tools like circular saws and reciprocating saws.
What charger works with the DCB204?
The DCB204 is compatible with all DEWALT 20V MAX* chargers including the DCB115, DCB1104, and DCB1106. The DCB1106 fast charger reduces charge time to approximately 60 minutes versus about 90 minutes on the standard DCB115.
What does XR mean on the DCB204?
XR stands for eXtended Runtime. DEWALT XR batteries use premium cylindrical cells that deliver more consistent power output under sustained load compared to standard 20V MAX compact packs, resulting in more usable work per charge.
