Milwaukee M12 Battery Compatibility
Like the M18, Milwaukee’s M12 system offers complete internal compatibility: every M12 battery works with every M12 tool and charger. This makes building out an M12 kit simple — any battery you own will work with any tool you add to the system.
TL;DR
All M12 batteries are compatible with all M12 tools and chargers — universally confirmed by Milwaukee.
M12 batteries do NOT work in M18 tools (different voltage and connector).
All M12 REDLITHIUM battery types (CP, XC, High Output) are cross-compatible within M12.
The Multi-Voltage Charger charges both M12 and M18 batteries.
Confirmed by the official Milwaukee M12 Batteries & Chargers page.
Compatibility Rules
Milwaukee’s official page states that all M12 batteries are compatible with M12 tools and chargers. This applies to all M12 REDLITHIUM battery variants — from the compact 1.5Ah CP through to the 6.0Ah High Output. The M12 connector is specific to the 12V platform and will not physically fit M18 tools.

Charger Notes
Any M12 charger will charge any M12 battery. If you own both M12 and M18 tools, the Milwaukee Multi-Voltage Charger is an efficient option that accepts batteries from both platforms, reducing the number of chargers you need.
The Milwaukee M12 system is Milwaukee’s sub-compact 12V platform, delivering professional-grade performance in the smallest possible footprint. With over 100 tools, M12 is the world’s largest sub-compact system. All M12 batteries (48-11-2401, 48-11-2402, 48-11-2410, 48-11-2412, 48-11-2420, 48-11-2425, 48-11-2430, 48-11-2440, 48-11-2460, 48-11-2462 and CP/XC variants) are compatible across all M12 tools.
