Will the Makita BL4050F 40V max XGT 5.0Ah battery work with the Makita DC40RA 40V max XGT rapid optimum charger?
Yes. Both use Makita 40V max XGT battery platform.
Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.
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).
