Good to know
  • M12 packs are stick-style batteries that go into the tool handle; they do not fit M18 tools, and M18 packs do not fit M12 tools.
  • Milwaukee's 48-59-1812 multi-voltage charger charges both M12 and M18 batteries.
  • Not interchangeable with M12 batteries or with Milwaukee MX FUEL (equipment-class) batteries.
  • FORGE batteries work on any M18 charger, but the advertised fast charge needs the M18 Dual Bay Simultaneous Super Charger (48-59-1815).
  • Large HIGH OUTPUT/FORGE packs work in every M18 tool but add size and weight to compact tools.
