Why

  • ✓ Both use Makita 40V max XGT battery platform.

Good to know

  • Not cross-compatible with 18V LXT: XGT batteries do not fit LXT tools and LXT batteries do not fit XGT tools.
  • Makita's ADP10 adapter lets a 40V max XGT charger charge 18V LXT batteries. That is charging only, not tool compatibility.
  • XGT batteries need XGT chargers (e.g., DC40RA).
