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.
