Editor's Pick: If you have a lot of M12 tools on hand, keeping two 4.0Ah batteries and rotating them makes life much easier. There's a fuel gauge on the battery itself, so one press tells you how much charge is left—no more suddenly running out of power halfway through a job. A full charge takes just over an hour, and it barely loses charge when sitting idle. The battery has a flat bottom, so it stands upright on its own when attached to a tool, staying stable on a desk or the floor.
