Important Product Questions
What does the amp-hour rating mean?
This pack is rated at 5.0 Ah. That is battery capacity, not a promise of 5.0 hours of tool runtime; runtime depends on the tool and task.
Will it work in the other Milwaukee battery system?
No. This is an M18 pack. M12 and M18 batteries are different systems; match the battery to the tool and charger.
What is distinctive about this pack?
Its housing provides increased protection against common oils, greases and solvents. It is resistant, not a claim of immunity to every chemical.
