DEWALT says FLEXVOLT batteries power supported 20V MAX and 60V MAX tools. That does not mean an ordinary 20V MAX battery can run a 60V MAX-only tool.
Understand the FLEXVOLT pack
DCB606 is a FLEXVOLT 20V/60V MAX battery. The system page explains how FLEXVOLT packs change operating voltage according to the supported tool. This is a property of the FLEXVOLT pack itself.
Do not reverse the rule
DCB205 is an ordinary 20V MAX pack. The FLEXVOLT system statement is not evidence that DCB205 powers a 60V MAX-only tool. The checker treats the two directions separately.
Check individual exceptions
A tool’s manual can narrow the general system rule. For a pair not named or supported by the available documents, the site reports unknown or conditional instead of a broad yes.
