Milwaukee's M18 FUEL system is one of the most advanced cordless technologies available, delivering first-rate power, longer run times and outstanding durability. The M18 battery packs contain a DPM (Digital Power Management) system that ensures the batteries maintain optimal charge and discharge cycles, with built-in over temperature and overcharge protection.
The M18 range of Milwaukee tools can be powered any of the 18 volt, Lithium-Ion battery packs (2.0Ah, 4.0Ah or 5.0Ah).
The smaller M18 2.0 Ah battery packs offer superior power in a much more compact package than traditional NiCd / NiMH batteries. The larger M18 5.0 Ah battery packs offer increased performance and extended run time.
The new Milwaukee Multi-Voltage Charger (M12-18C) is a dual charging unit that can recharge both M18 and M12 battery packs. The charger recharges batteries in sequence ( firstpack inserted charges first), ensuring less time is needed to manage charging cycles.
