Frequently Asked Questions
What is the difference between the 48-11-1855 and the standard 48-11-1850 XC5.0 battery?
The 48-11-1855 is part of Milwaukee's HIGH OUTPUT™ generation. While both deliver 5.0 amp-hours of runtime, the 48-11-1855 utilizes upgraded cell architecture and electronics to supply 50% more peak power under load and operates significantly cooler during demanding applications.
What does "PWR Level 3" mean?
PWR Level is Milwaukee's standardized scale for battery output performance. A PWR Level 3 rating signifies that this pack delivers the high current discharge required to optimize performance on heavy-draw tools like table saws, large angle grinders, and high-torque impact wrenches without bogging down.
Will this battery work with all my older Milwaukee M18 tools and chargers?
Yes. The 48-11-1855 is 100% backward and forward compatible with the entire M18™ ecosystem of 300+ cordless tools, and charges on any standard M18™, Rapid, or Super Charger.
How fast does the M18 HIGH OUTPUT XC5 battery recharge?
Recharge times vary by charger: approximately 39 minutes on an M18™ Super Charger, 60 minutes on an M18™/M12™ Rapid Charger, and roughly 105 minutes on a standard Milwaukee multi-voltage charger.
How does this battery handle drops and moisture on the jobsite?
The pack features upgraded shock-absorbing interior cell separators to guard against severe drops and vibration. In addition, water-drain channels route accidental rain or fluid exposure directly away from internal electronics and out the base of the pack.
