What compatibility data says
- battery to tool — GDT01Z: conditional. Both product pages identify XGT; the exact tool manual should be checked for any model-specific exclusions.
- charger to battery — DC40RA: conditional. The DC40RA official manual lists BL4040 in its charging table.

- Use an XGT-approved tool and charger; an LXT receiver is not a substitute.
