Description
Milwaukee 48-59-1818 M18 and M12 Four Bay Simultaneous Super Charger with PACKOUT Compatibility
Eliminate jobsite charging bottlenecks with the Milwaukee 48-59-1818 M18™ & M12™ Four Bay Simultaneous Super Charger. Built for high-demand crews, this commercial-grade multi-battery charging station charges up to four batteries concurrently—delivering speeds up to 10x faster than standard sequential chargers.
Engineered with Milwaukee’s COOL-CYCLE™ Active Cooling System, internal fans force high-velocity airflow through compatible batteries to cool hot packs rapidly and begin full-speed charging immediately after heavy use. The intelligent bay configuration includes (2) dedicated M18™ bays and (2) M18™/M12™ hybrid bays, allowing you to power both cordless ecosystems from a single unit. With integrated PACKOUT™ cleats, it locks directly onto your existing modular stack for hassle-free jobsite transport and organization.
Key Features:
- True Simultaneous 4-Bay Fast Charging: Powers four batteries simultaneously rather than cycling one by one.
- CHARGE ADAPT™ Power Management: Dynamically distributes electrical current across all bays to maximize charging efficiency and minimize downtime.
- COOL-CYCLE™ Active Cooling: High-speed cooling fan system rapidly cools hot packs to initiate high-amperage supercharging faster.
- Full PACKOUT™ Modular Integration: Mounts seamlessly into any Milwaukee PACKOUT™ stack with a built-in top carry handle for portability.
- Versatile Hybrid Bay Design: Features 2 dedicated M18™ bays plus 2 dual-compatible M18™/M12™ bays to consolidate multiple chargers into one footprint.
- REDLINK™ Intelligence: Continuously monitors individual cell voltage, thermal load, and state of charge to prolong battery pack lifespan.

Frequently Asked Questions
Does this charger charge all four batteries at the same time or sequentially?
The Milwaukee 48-59-1818 is a true simultaneous charger. Unlike sequential chargers that charge batteries one at a time, this Super Charger distributes power to charge up to four batteries concurrently using CHARGE ADAPT™ technology.
Can I charge both M12 and M18 batteries together?
Yes. The charger features two dedicated M18™ bays and two hybrid bays that accept either M18™ or M12™ batteries, allowing you to charge both platforms at the same time.
What is the COOL-CYCLE™ Active Cooling System?
COOL-CYCLE™ uses high-speed internal cooling fans to force air through compatible battery packs (such as M18™ REDLITHIUM™ FORGE™ batteries). This rapidly drops the internal cell temperature of hot batteries off the tool, allowing the supercharging cycle to start much faster.
How does it attach to my Milwaukee PACKOUT™ system?
The bottom of the charger features integrated PACKOUT™ locking cleats, allowing it to latch securely to the top of any PACKOUT™ tool box, rolling chest, or organizer for stable transport and storage on the jobsite.
Will this charger work with older M18 and M12 REDLITHIUM batteries?
Yes. It is fully backward-compatible with all Milwaukee M18™ and M12™ lithium-ion batteries. While older standard packs will not utilize the COOL-CYCLE™ active venting, they will still benefit from rapid, simultaneous charging.
