  • High quality
Great battery for Milwaukee tools. Holds a charge during heavy use and built to last.

  • Great battery/price
Perfect match to the original. Works great

  • Great capacity
Great addition to M12 tools. Extra capacity, longer tool life. Nicely priced and the larger base makes it perfect for my M12 screwdriver. Makes setting it down and picking it up a breeze.

  • Great product
Milwaukee’s batteries are really made for the professional contractors so for do it yourselfers like me it a bit of overkill but to me that’s exactly what I want.

  • Authentic Milwaukee Battery
Works perfectly and exactly what I expected. It's just as powerful as the battery I got with my rotary drill (M12). The capacity and duration are the same!
