18V power tool batteries: why the platform matters

An 18V label appears across unrelated power tool systems. Match the system, exact model and manufacturer instruction before deciding whether a battery fits or charges.

Different 18V systems

Nominal and maximum labels

DEWALT describes its 20V MAX batteries as 18V nominal. Makita LXT, Milwaukee M18 and Bosch Professional have their own 18V systems. Similar voltage text does not bridge their connectors or approved tool lists.
