What fits Milwaukee M12?

Any M12 battery fits any M12 tool. Higher-capacity XC and High Output packs are physically larger and add runtime but power the same tools; a compact subcompact tool can feel nose-heavy with a 5.0Ah pack.

Voltage
12V MAX (10.8V nominal)
Chemistry
Lithium-ion REDLITHIUM. Slide-on M12 pack footprint.

Common tools: M12 FUEL drill/driver, M12 impact driver, M12 ratchets, M12 heated gear

Cross-compatibility notes

M12 and M18 are NOT interchangeable — different voltage and footprint. A dual-bay M12/M18 charger charges both, but the tools themselves are platform-specific.
