This is a \u003cstrong\u003ebattery charger\u003c\/strong\u003e designed for \u003cstrong\u003echarging and managing Milwaukee M12 battery packs\u003c\/strong\u003e. Model Number: \u003cstrong\u003e48-59-1204\u003c\/strong\u003e. If you are rotating batteries through several cordless tools, this charger cuts down the constant shuffle of moving one pack at a time on and off a single-bay charger.\u003c\/p\u003e \u003cp\u003eWhat matters here is the layout and charging logic. The charger accepts up to four M12 battery packs and charges them sequentially, one battery at a time. In practical use, that means the battery currently being charged gets full attention from the charger rather than sharing charging output with the others. For crews and serious DIY users, that makes it easier to keep a clear battery rotation going through drills, impact drivers, inspection tools, lights, and other M12 cordless tools.\u003c\/p\u003e \u003cp\u003eMilwaukee also built this charger around jobsite practicality instead of just raw charging speed claims. The housing is slim enough for a bench top, storage shelf, or service van setup, and it includes integrated hang holes for vertical key-hole mounting. If your charging area is tight, that wall-mount option matters. It gets the charger up off the work surface and keeps battery packs organized instead of piled around loose.\u003c\/p\u003e \u003cp\u003eThe onboard charge indicator gives you a quick read on charging status without having to pull a pack off the charger and guess. Milwaukee also includes a skip button, which is one of those small features that actually makes the tool more useful day to day. If you need one specific battery next, you can move charging priority without unloading the whole charger. That is a real time-saver when one tool is critical and the rest can wait.\u003c\/p\u003e \u003cp\u003eOn the electronics side, this charger uses Milwaukee REDLINK Intelligence to communicate directly with the battery pack. That system monitors cell voltage, temperature, and charge status while charging. The reason that matters is simple: better battery monitoring helps protect pack health and supports more consistent charging performance over time. If you have invested in M12 REDLITHIUM batteries, this is the kind of charger setup that helps you get more usable life out of that investment.\u003c\/p\u003e \u003cp\u003eAs a platform tool, the charger is specifically designed for the Milwaukee M12 battery system and charges all M12 batteries. It runs from a standard 120V electrical outlet and delivers up to 3 amps max output. This is not a dual-platform charger and it is not meant for M18 packs. If your setup is primarily M12, though, that single-platform focus is exactly the point.\u003c\/p\u003e \u003cp\u003eWho should buy it? This charger makes the most sense for technicians, electricians, plumbers, HVAC crews, remodelers, and anyone else who runs several M12 batteries in a normal workday. It is also a smart shop charger if you keep spare packs ready for smaller cordless tools. If you only own one battery and one tool, a single-bay charger is enough. If you are already cycling multiple M12 packs, the Milwaukee 48-59-1204 M12 Four Bay Sequential Charger is the cleaner, more efficient setup.\u003c\/p\u003e \u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-benefits\" class=\"acc\"\u003e \u003csummary\u003e\u003ch2\u003eKeep Your M12 Batteries Organized\u003c\/h2\u003e\u003c\/summary\u003e \u003cdiv class=\"acc-body\"\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"img\"\u003e\u003cimg src=\"https:\/\/www.milwaukeetool.com\/--\/web-images\/sc\/17c21cbc74744a1cad5dfd805ccc8b5b?hash=710cec8c3edecf45762971fac8605faa\u0026amp;lang=en\" alt=\"Milwaukee 48-59-1204 M12 Four Bay Sequential Charger shown on a clean background with four M12 battery charging bays for shop or jobsite battery management\" class=\"tnblock-img\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"copy\"\u003e\n\u003cp\u003eThis M12 charger is built for users who need a dedicated battery station instead of a single loose charger rolling around the bench or truck.
