Good to know
  • Makita's current 'B' batteries (BL1840B/BL1850B/BL1860B) are labeled 'Compatible only with Star Protection tools, indicated by the Star Symbol and/or Yellow Battery Receiver under the tool.' Check older LXT tools for the star mark.
  • X2 LXT tools (e.g., XSH06Z) need two 18V LXT batteries installed at once.
  • Not compatible with Makita 40V max XGT tools. Makita's ADP10 adapter only lets an XGT charger charge LXT batteries; it does not let LXT batteries run XGT tools.
  • The DC18RC charger also charges Makita 14.4V lithium-ion batteries, but 14.4V batteries are a different class from 18V LXT.
