The DCB204-2 is a 2-pack of DEWALT's 20V MAX* XR 4.0Ah lithium-ion batteries, offering a strong balance of runtime and weight for professional use. Each battery provides more runtime than the standard 2Ah compact pack and less bulk than a full 5Ah or 6Ah battery, making the 4Ah size popular with tradespeople who need extended performance without added weight. Compatible with all DEWALT 20V MAX* tools and chargers. Each battery includes an LED state-of-charge indicator. Buying in a 2-pack supports continuous workflow — one battery runs the tool while the other charges. Each battery carries DEWALT's 3-year limited battery warranty.
How does the DCB204 4Ah compare to the DCB205 5Ah?
The DCB204 is slightly lighter and less expensive than the DCB205, making it a good choice when maximum runtime is not required. Reviewers often choose the 4Ah for daily driver tools like drills and impact drivers, reserving the 5Ah for longer-running tools.
Is the DCB204-2 2-pack compatible with all DEWALT 20V MAX chargers?
Yes. Both batteries charge with all DEWALT 20V MAX chargers, including the DCB115, DCB1104, and DCB1106. The fast charger reduces charge time significantly compared to the standard charger.
What is the XR designation on the DCB204?
XR stands for eXtended Runtime, DEWALT's premium cylindrical cell chemistry. XR batteries use higher-quality cells that deliver more consistent power output under load versus standard 20V MAX compact packs.
Does the DCB204-2 2-pack offer better value than two individual DCB204 batteries?
Yes. The 2-pack typically costs less than buying two singles. Reviewers who run multiple tools or work on extended projects find the 2-pack a practical purchase for maintaining uninterrupted workflow.
Can I use the DCB204 with DEWALT ATOMIC 20V MAX tools?
Yes. The DCB204 is fully compatible with DEWALT 20V MAX* ATOMIC tools and all other 20V MAX* tools and chargers.
