  • Great battery.
I went cheap and bought the used one for 39 bucks. Glad I did. It is an original battery however, came in a plastic bag due to being used. It charged fine and has plenty of power. I drove some 5” wood screws with no issues at all.

  • Milwaukee quality says it all
This M12 battery has the extra needed power, and at a decent price. It's compatible with all M12 tools, charges quick, provides great power, and functions as designed

  • 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 ... show more

  • Genuine Milwaukee
It’s the 4.0 but it works absolutely fantastic, the 5.0 might be a little better but not for the price
