The DCBP520-2 is a 2-pack of DEWALT's flagship POWERSTACK 5.0 Ah batteries, pairing maximum capacity with the revolutionary flat pouch cell architecture that delivers 50% more power and 2X the cycle life of standard 20V MAX cylindrical-cell packs. Each battery provides the capacity of a traditional 5.0 Ah XR pack in a more compact, lighter body that runs cooler under sustained load. The 2-pack format supports professional all-day workflow with one battery running while the other charges. Compatible with all DEWALT 20V MAX* tools and chargers. Covered by DEWALT's 3-year limited battery warranty.
What is the value of buying the DCBP520-2 2-pack versus two individual DCBP520 batteries?
The DCBP520-2 typically provides a per-battery savings compared to two singles. For professional users who need continuous runtime throughout the workday, the 2-pack is the practical choice.
How does the DCBP520-2 compare to two standard DCB205 5Ah XR batteries?
Each DCBP520 in the 2-pack delivers the same 5.0 Ah capacity as the DCB205 but in a more compact, lighter form using pouch cell technology. Reviewers note the DCBP520 runs cooler, delivers more instantaneous power, and has a longer projected cycle life than the standard DCB205.
Are the DCBP520-2 batteries compatible with all my existing DEWALT 20V MAX tools?
Yes. Both batteries are fully backward compatible with all DEWALT 20V MAX* tools, chargers, and accessories including older tools in the platform.
How long does each DCBP520 battery take to charge?
With a DEWALT DCB1106 or DCB1104 fast charger, each 5.0 Ah POWERSTACK battery charges in approximately 60 minutes. The efficient pouch cell design minimizes heat buildup during charging.
Does the compact size of the DCBP520-2 batteries affect performance in high-draw tools?
No. The POWERSTACK pouch cell architecture is specifically designed to maintain voltage under high-draw conditions. Reviewers using impact wrenches and circular saws report the DCBP520 performs equal to or better than standard 5Ah packs under load.
