                        These are great batteries. I love the smaller M12 batteries because they can fit in tighter spaces on my Milwaukee ratchet. Also, the work good on my drill and impact. A+
                        by
                        Amazing! These taking a beating and dont quit. The 3 pack was worth the money and allows me to power through my jobs without having to worry about losing power or not finishing the job. Highly recommend!
                        by
                        This is my preferred size battery for all my M12 tools for extended life and usually also s allows tool to stand up on its own. The photo shows how an M12 drill can stand on its own with this form factor battery.

                        I bought the Milwaukee stubby and I had the 2.0 and 4.0 battery already so I bought just the tool. It worked great with this batteries but I kept hearing that if you wanted the full power of the tool you needed the 5.0. I can feel a real difference with this battery!!
