Milwaukee has a New 4-Bay Super Charger for M18 and M12

Milwaukee recently announced a new 4-bay M18 and M12 Super Charger, 48-59-1818, featuring simultaneous charging of up to 4 batteries.

This is the second M18-compatible charger with Cool-Cycle capabilities, allowing it to quickly cool down M18 FORGE 8Ah and 12Ah batteries for faster charging.

The charger has 4x M18 battery slots and 2x M12 battery slots.

Two of the M18 slots are hybrid bays, allowing up to 4 M18 batteries to be charged simultaneously. Or, you can charge 2 M18 and 2 M12 batteries at the same time.

The new Milwaukee Super Charger features an adaptive charge distribution feature, allowing it to dynamically allocate power for maximum productivity. We’ll have more information about this feature, and if it works differently compared to the dual bay charger, at a later time.

The charger can recharge (4) M18 FORGE 12Ah batteries to 100% in 90 minutes.

ETA: June 2026

The new charger was announced at the 2026 World of Concrete trade show. See more WOC 2026 tool news:
