Will the DeWalt DCB606 FLEXVOLT 20V/60V MAX 6Ah battery work with the DeWalt DCD805B 20V MAX XR 1/2 in. brushless hammer drill/driver (tool only)?
Yes. DeWalt FLEXVOLT 20V/60V MAX battery platform works where DeWalt 20V MAX battery platform (incl. XR and POWERSTACK) is expected.
Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.
Why
- ✓ DeWalt FLEXVOLT 20V/60V MAX battery platform works where DeWalt 20V MAX battery platform (incl. XR and POWERSTACK) is expected.
Good to know
- XR and POWERSTACK are 20V MAX batteries, not separate platforms; DeWalt product pages say they are compatible with all 20V MAX tools and chargers.
- '20V MAX' is the maximum initial (no-load) voltage; DeWalt states nominal voltage is 18V. Outside North America the same battery family is marketed as DeWalt '18V XR' (same pack, different marketing; reported by ToolGuyd, not a DeWalt page). Chargers are region-specific because of mains voltage (120V vs 230V).
- Not interchangeable with DeWalt 12V MAX batteries.
- Black+Decker 20V MAX and Craftsman V20 batteries are separate systems even though Stanley Black & Decker owns all three brands; they do not fit DeWalt 20V MAX tools without third-party adapters.
- DeWalt's DCA1820 adapter lets 20V MAX batteries run most older DeWalt 18V (NiCd/NiMH) tools, with exceptions; DeWalt says not to use it with DCB200/DCB204/DCB205 or batteries over 4Ah in DC970/DC759 compact drills.
- DeWalt lists FLEXVOLT batteries for its 60V MAX tools (e.g. the DCS578B); 20V MAX batteries aren't listed for them.
- 120V MAX tools take two FLEXVOLT batteries.
- FLEXVOLT batteries charge on DeWalt 20V MAX chargers.
- Ah ratings (e.g., 9Ah) apply in 20V mode; in 60V mode usable Ah is one-third (watt-hours are the same, e.g., DCB609 = 180 Wh).
- DeWalt states maximum initial voltage is 20/60/120V and nominal voltage is 18/54/108V.

- DeWalt 20V MAX battery platform (incl. XR and POWERSTACK): DeWalt's main slide-on battery system; every 20V MAX battery (standard, XR, POWERSTACK) fits every 20V MAX tool and charger, and FLEXVOLT 20V/60V batteries also work in 20V MAX tools. (DeWalt DCB203 product page; DeWalt DCA1820 support article).
- DeWalt FLEXVOLT 20V/60V MAX battery platform: DeWalt FLEXVOLT batteries automatically switch between 20V and 60V, so they run both 20V MAX tools and 60V MAX (and 120V MAX) tools. (DeWalt FLEXVOLT battery system page).
