    This is my light weight version of the bigger brothers in my Milwaukee tool lineup. For quick and smaller jobs this is the drill I use.

    I bought this 2.0 battery for my M12 tools that needed a little more run time over the regular battery, and didn’t want the weight & bigger size of the 4.0. It’s the same size & looks exactly like the regular battery and the only way of knowing that it’s a 2.0 is the front label with the small red 2.0, or the tiny model # on the bottom. Milwaukee should make the 2.0 numbers much larger and backed by white like the M12 logo to make it easier to see in a tool bag or in limited light. The main thing is I did notice a longer run time on my hand held M12 vacuum (which is a power hog) and on my drill (I use it with a wire wheel for paint removal on wright iron railings).

    Excellent battery is not heavy, it charges fast, it serves you in places where there is almost not much space, good battery design and the power lasts you two hours working hard, good special Home Depot 🙂

    Great addition to anyone’s tool box..I was hoping for a bit more torque (I’m an auto tech) however where this falls short I have other reinforcements.

    nice not having to change out the typical 2ah batteries twice as frequently compared to the 4ah units. never hurts having more bags. I like to use them for less used tools to make easy to grab “kits” for when they are needed

    Great battery for my low use tools like flashlight or hoodie. Also as back up battery when charging the bigger xc one.
