DEWALT® 20V MAX* XR POWERSTACK™ 1.7Ah Compact Battery

Model number
DCBP034

The DCBP034 is DEWALT's entry-level POWERSTACK battery, delivering 1.7Ah of capacity in a 25% smaller footprint than standard 20V MAX cylindrical-cell packs. Using proprietary flat pouch cell technology, it provides 50% more power and twice the cycle life of standard compact batteries. Designed for tight-quarters and overhead work where a low-profile pack improves control, the DCBP034 works with all DEWALT 20V MAX* tools and chargers. It includes a push-button LED fuel gauge and an impact-resistant overmolded rubber base. Sold also as the DCBP034C starter kit with charger. Covered by DEWALT's 3-year limited battery warranty.

§ FAQ

What is the POWERSTACK technology in the DCBP034?

POWERSTACK uses flat lithium-ion pouch cells stacked inside the pack instead of traditional cylindrical cells. This design delivers more conductive surface area, resulting in faster power delivery, a 25% smaller footprint, and twice the cycle life compared to standard 20V MAX compact batteries.

Is the DCBP034 1.7Ah battery compatible with all my 20V MAX tools?

Yes. The DCBP034 is fully compatible with every DEWALT 20V MAX* tool and charger. Reviewers confirm it works with drills, impact drivers, ratchets, and demolition hammers.

How does the DCBP034 compare to the standard DCB203 2Ah battery?

The DCBP034 is 25% smaller and lighter than standard cylindrical 20V compact packs, making it better for tight-quarters and overhead work. Despite the lower Ah rating, pouch cell technology delivers 50% more instantaneous power output. For extended runtime, the DCBP320 (3.5Ah POWERSTACK) or DCBP520 (5Ah POWERSTACK) are better choices.

Does the DCBP034 charge faster than other DEWALT batteries?

Reviewers note that the DCBP034 charges very quickly — in approximately 30 minutes or less with a DEWALT fast charger — because of the lower capacity combined with the efficient pouch cell chemistry.

Why does the DCBP034 feel so much more powerful than a regular 2Ah battery?

The POWERSTACK pouch cell architecture allows more consistent current delivery across the discharge cycle, particularly under high-load conditions. Reviewers using it with ratchets and impact wrenches note immediate feel of extra torque response compared to older cylindrical-cell compact packs.
