Key Features
Serious Magnetic HoldBuilt with five 100 lb rare earth magnets, this cover is made to hold a compatible battery and tool more securely on steel surfaces so they stay where you put them. Fits High Output PacksThe STS Auto Design M18H6 Milwaukee M18 Hi-Output 6.0Ah/8.0Ah Magnetic Battery Cover is designed specifically for Milwaukee M18 High Output 6.0Ah and 8.0Ah batteries, so fit is purpose-built instead of generic. Light Add-OnAt 0.5 lb, it adds magnetic storage capability without turning your battery into a bulky brick. That matters when you are moving tools around the shop or truck all day.
Overview
The STS Auto Design M18H6 Milwaukee M18 Hi-Output 6.0Ah/8.0Ah Magnetic Battery Cover is a battery-mounted magnetic accessory built for users who want a more secure way to stage cordless tools and batteries on steel surfaces. This is a magnetic battery cover designed for securing compatible Milwaukee M18 High Output batteries and attached tools during storage or positioning in a shop, service truck, or fabrication space. Model Number: M18H6. Variant SKU: MW1868HOBK.
What makes this product matter is simple: it turns a compatible Milwaukee battery into a magnetic mounting point. According to the product data, the cover uses five 100 lb rare earth magnets. That is the spec that does the heavy lifting here. Instead of setting a tool down on the floor, balancing it on a lift, or digging for a place to park it between tasks, you can hold it against a ferrous surface with far more confidence.
This is not a universal fit accessory, and that is a good thing. It is designed specifically for Milwaukee M18 High Output 6.0Ah and 8.0Ah battery packs. That dedicated fit matters because a loose magnetic adapter is not helpful on the job. The product images show a molded, battery-specific base that wraps the lower portion of the pack rather than acting like a generic stick-on magnet.
From a practical standpoint, this accessory makes the most sense anywhere steel is already part of the workspace. The in-use image shows the mounted battery and tool hanging from shop equipment, which tells you exactly where this product earns its keep: lifts, tool boxes, fab tables, shelving, equipment frames, and service setups where quick access matters. If you work around metal all day, this kind of add-on can save a surprising amount of small motion and clutter.
Weight is listed at 0.5 lb, so it is light enough to stay useful without defeating the point of a cordless setup. That is an important detail for a battery-mounted accessory. Too much added weight would make the tool awkward or make the battery less practical to move between tools. This one is intended to add holding power, not turn the pack into a specialty piece that never leaves the cart.
It is also important to be clear about what this product is not. It is not a battery, charger, or power tool. It is a magnetic cover or mount only. If you are buying it, you are buying the magnetic mounting solution itself. The battery, charger, and tools shown or referenced are sold separately.
This accessory is best suited for mechanics, fabricators, installers, fleet techs, and serious garage users who already run Milwaukee M18 High Output 6.0Ah or 8.0Ah batteries and want a cleaner way to store or stage tools on steel. If that is your setup, the STS Auto Design cover solves a real annoyance with a simple physical solution instead of another clip, hook, or improvised shelf.
Keep Tools Off the Floor
If you work around steel benches, lifts, cabinets, or equipment, this accessory gives your compatible battery pack a real parking spot. That means less bending down, less clutter, and less chance of a tool getting knocked off a ledge.
