    Found these on sale and still a good physical size for me. 4 amp will be fine for my needs. Use them in a 12v 1/4 inch impact wrench, so far so good.

    5.0 out of 5 stars Great oem battery

    Super happy with purchase, I know some people were concerned about it being a genuine Milwaukee battery and it is. There are tons of offbrands out there and I have bought a few that work legit but don't label it "Milwaukee" . My package came in a clamshell Milwaukee packaging, i have heard some say theirs came packaged differnt.

    For the price I had assumed they could be a factory blemished item which is why the price was lower.. a website for ryobi and ridgid called directtoolsoutlet dot com actually sells almost new reconditioned and factory blemished tools and batteries etc so I thought this was the case with the milwaukee battery but nope.

    Very please and I see the price has gone up about $10 from my purchase date, i also got a 2 pack of 6.0ah offbrands for about $40 that are very well made and soo far work well.

    Why pay top dollar when you can get actual milwaukee betteries for less and even still some of these offbrands are pretty legit on their knockoffs. I run mainly my m12 lantern and usb charger with knockoffs just because but a guy on youtube has had knockoff m18 batteries going strong after 3 years..

    To wrap up this novel, these are definately worth the price as legit milwaukee batteries. As popular as milwaukee is though there are some good knockoffs

    4.0 out of 5 stars It’s a great battery, but I’m not sure it’s genuine Milwaukee
    Reviewed in the United States on July 30, 2019
    The battery works great. I’m just not convinced it’s a genuine Milwaukee battery.

    FirsI, like others, I received my battery wrapped in plastic wrap, not in molded plastic retail packaging like one would expect. Suspicious.

    Also, the battery is hit-or-miss in my two-month-old Milwaukee charger. More often than not, the charger blinks red when I insert this battery, indicating the battery is overheated. Oddly, this has always happened with a cold battery. As a work-around I then insert the battery into to my *old* Milwaukee charger, a trick that has been successful in charging the battery.

    All that being said, once charged the battery operates flawlessly and lasts a good long time. Thus, I am giving it four stars.

    As always, the price for Milwaukee products is high but the quality makes it worthwhile.
