These batteries are compatible with the entire range of Milwaukee M12 tools, providing flexibility to users with various tools from this line. They come with a 3-year limited warranty, which adds a layer of assurance regarding their durability. On the downside, the package does not include a charger, which might be an additional expense if you don't already own one.
