Best DeWalt 20V MAX XR battery packs under $100
Researched by Deal.ai's shopping agent across stores on November 2, 2026. Prices below are today's.
Top pick: the 20V MAX XR POWERPACK 4Ah (DCB2104). It's the XR pack to buy — the newer Powerpack cell design runs cooler and lasts longer than the standard 4Ah, and 4Ah is the sweet spot of runtime without making a drill nose-heavy.
Who the others suit:
- XR Premium 5.0Ah — most runtime per charge for saws and grinders; heavier in a drill.
- Standard 4.0Ah (DCB204) — cheapest way into 4Ah if you don't need XR cells.
- 2.0Ah / 1.7Ah compact — lightest for overhead work and small drivers; short runtime.
- 5.0Ah DCB205 — a solid mid-size all-rounder, but older cells than the XR packs.
All are 20V MAX, so they fit every DeWalt 20V MAX tool and charger.
