The Milwaukee 48-59-1204 M12 Four Bay Sequential Charger is designed for users who manage several M12 batteries but do not need true simultaneous charging. Its four-port layout lets crews stage multiple packs in one location, then cycle through them sequentially as the charger works from bay to bay. That makes it useful for service departments, installers, and workbenches where batteries accumulate during the day and can be charged in queue overnight or between shifts. It is a stronger organizational choice than a single-bay charger for M12-heavy setups.

No. This charger is for the M12 platform only.
