    This is a very powerful battery pack and you can feel the difference when using something like a impact drill on lug nuts or something similar. I was worried that because of the low price that this may be a counterfeit unit. I had just purchased the identical one from HD and it is 100% identical in every aspect. I kept them both and they perform identically. I don't know why I would ever purchase one somewhere else now. I can only speak for this seller "industrial tools" here on Amazon

    Last a lot longer than the 2.0 and 3.0. Adds much needed torque for use in the winter. When working on roofs and in walk in freezers, a battery that holds up in the cold is crucial

    I bought this for my Milwaukee's 3/8" impact gun. It really lasts for a long time without recharging, so I would say it is worth it over the regular pack.

    Seems legit

    Reviewed in Canada on December 26, 2025

    Seems legit so far
    I’ve only had it for a few days and haven’t had the opportunity to really test it properly on some of the more power hungry m12 tools, but it seems legit.
    It came in, what looked to be, genuine Milwaukee packaging. I even compared it to a few unboxing videos online, na everything checked out, no grammatical errors or misprints. The sticker on the bottom of the battery looks good too.
    Hoping it continues to impress.
