Key Features
Overview
The Milwaukee 48-22-8339 PACKOUT M18 Battery Rack is a wall-mount battery storage rack built for organizing Milwaukee M18 battery packs in a PACKOUT shop storage setup. This is a battery rack designed for shop organization and quick access battery storage. Model Number: 48-22-8339. If you already run M18 tools and want your batteries off the bench, visible, and easy to grab, this is the piece that cleans up the mess fast.
What makes this rack useful is that it is not just a shelf. Milwaukee designed it with clip-in M18 battery storage, so the batteries seat into the rack instead of just resting on a flat surface. That gives you more secure battery storage and keeps packs from getting knocked off when the wall gets bumped or when you are loading other PACKOUT accessories nearby. It is optimized to store up to four M18 batteries, and Milwaukee states it fits M18 batteries of any size.
The overall footprint is compact at 4 inches long, 4 inches wide, and 13 inches high, which makes it easier to add battery storage without giving up much wall space. At 0.8 pounds, it is light enough to integrate into a modular wall layout without adding much dead weight. For a garage, trailer, service area, or dedicated tool room, that compact size matters because it lets you stack storage vertically and keep your charging station tighter.
Construction is listed as polymer and steel, which is the right mix for this kind of organizer. The polymer body keeps weight down and resists everyday shop wear, while the steel component helps support the mounting structure. Milwaukee positions this as part of the PACKOUT modular storage system, so the bigger advantage is not just holding four batteries. It is about creating a repeatable, organized system where batteries, chargers, hand tools, and accessories all have a fixed place.
On the mounting side, Milwaukee calls out secure attachment when paired with PACKOUT wall plates, and product feature data also notes that it securely locks onto wall plates and can slide onto tool box lids. That gives the rack more than one useful home depending on how you set up your PACKOUT storage. In a fixed shop, wall plates make the most sense. In a mobile setup, the ability to integrate with PACKOUT components helps keep the same batteries organized from van to bench.
Compatibility is straightforward and important. This rack is made specifically for Milwaukee M18 batteries and is part of the PACKOUT ecosystem. If you are on another battery platform, this is not a universal holder and it is not pretending to be. If you are already invested in Milwaukee cordless tools, though, it is a clean add-on because it supports the batteries you already own and the wall system you may already be building.
This rack makes the most sense for contractors, mechanics, shop owners, electricians, maintenance crews, and serious DIY users who have enough M18 batteries that loose storage becomes a daily annoyance. It is especially useful for anyone building out a PACKOUT wall organization system and wanting faster battery access near chargers, workbenches, or tool storage. If your batteries are always ending up in a pile, this is one of those small organization pieces that pays off every day.
Keep Batteries Visible and Ready
Battery storage works best when you can see every pack, grab one fast, and put it back in the same spot. That is exactly where this rack helps. Mounted on a PACKOUT wall plate, it turns loose battery clutter into a clean, repeatable setup.
