Introducing the Milwaukee 48-59-1818 M18/M12 Multi-Bay Super Charger

If you've ever been at a jobsite watching a single charger slowly work its way through a pile of dead batteries, Milwaukee has a new tool that's about to make that scene a thing of the past. The M18 & M12 Four Bay Simultaneous Super Charger (48-59-1818) is built to charge an entire crew's worth of batteries at once — and fast!
The Problem It Solves
Most job sites don't run on one battery. They run on a rotating stack of them — some charging, some in tools, some sitting dead waiting their turn. A charger that can only handle one or two batteries at a time becomes a bottleneck, especially for larger crews.
Key Features
- Portability: PACKOUT compatible, with a secure M18 latch design and a built-in carrying handle
- COOL-CYCLE Capable: High Speed Fan Cooling for COOL-CYCLE Capable Packs
- Charge Four Batteries at Once: Charge four M18 REDLITHIUM FORGE HD12.0 batteries to 100% in 90 minutes
- Smart Charging, Built-In: Every bay uses Milwaukee's REDLINK™ Intelligence, which communicates directly with the battery to monitor voltage, temperature, and charge status in real time
- 5 year warranty
Who Should Consider This Charger?
This charger is aimed at crews who need reliable, simultaneous charging throughout the day — whether that's getting everyone's batteries topped off before the morning start, keeping up during high-demand tasks, or handling the unexpected surge in battery use that always seems to happen right when you can least afford downtime.
