The DCBP520 is DEWALT's flagship POWERSTACK battery, delivering 5.0Ah in a compact body using revolutionary flat pouch cell technology. It provides 50% more power and 50% more work per charge compared to standard 20V MAX batteries, with 2X the lifespan of cylindrical cell packs. Despite matching the capacity of a traditional 5Ah XR pack, the POWERSTACK architecture produces a physically smaller, more balanced battery that stays cooler under load. Compatible with all DEWALT 20V MAX* tools and chargers. Features a 3-LED fuel gauge and an impact-resistant overmolded rubber base. Covered by DEWALT's 3-year limited battery warranty.
How does the DCBP520 compare to the standard DCB205 5Ah XR battery?
Both are 5Ah 20V MAX batteries, but the DCBP520 uses POWERSTACK pouch cell technology versus the DCB205's cylindrical cells. Reviewers note the DCBP520 feels noticeably more powerful on high-draw tools like impact wrenches and circular saws, stays cooler during heavy use, and the compact form factor improves tool balance.
Is the DCBP520 compatible with older DEWALT 20V MAX tools?
Yes. The DCBP520 is backward compatible with all DEWALT 20V MAX* tools and chargers, including older models. Reviewers confirm it works seamlessly across drills, impact drivers, circular saws, reciprocating saws, and outdoor power equipment.
Does the DCBP520 really deliver 50% more power than a standard 5Ah battery?
Reviewers confirm the power improvement is noticeable. The POWERSTACK architecture improves instantaneous current delivery, which translates to better tool response under load. One reviewer noted their 3/4-inch impact wrench pulled noticeably harder with the DCBP520 compared to a standard 6Ah XR pack.
How long does the DCBP520 take to charge?
With a DEWALT fast charger such as the DCB1106 or DCB1104, the DCBP520 charges in approximately 60 minutes. The charger included in the DCBP520C starter kit is compatible.
How does the DCBP520 feel in the hand compared to the standard 5Ah DCB205?
Reviewers consistently note that the DCBP520 is shorter and lighter than the DCB205. The rubber overmolded base provides a non-marring surface that protects finished work surfaces. The lower profile makes tools feel more balanced in overhead and tight-space applications.
Is the 2X lifespan claim for the DCBP520 accurate?
DEWALT rates the POWERSTACK at 2X the charge cycles versus standard cylindrical cells. Reviewers who transitioned from older 5Ah packs note the POWERSTACK batteries retain capacity better after repeated charges, though long-term field data is still building as the product is relatively new.
