I’ve been using these batteries with my Milwaukee tools for a few days now, and honestly, they’ve been great. They fit perfectly, charge up quickly, and hold power just like the originals. I was skeptical at first because of the price, but so far no issues at all. I’ve used them with my drill and impact driver on a couple of projects—plenty of power, no overheating, and the charge lasts a good while. The little battery level indicator is also a nice touch. For the price of one OEM battery, I got two of these and they’ve been doing the job just fine. If anything changes long-term, I’ll update the review—but for now, definitely worth the buy.

Great replacement batteries for my impact. After 3 years of use my old battery was breaking in pieces, it was hard to use my impact , i didnt want to pay 60$ for a single battery but at the same time I was afraid of trying a different one. I decided to give it a try and i dont regret it, its working like new again and the best part is i got 2 batteries for the price of one.

The media could not be loaded. Ok I'd like to give 5 stars but I cant...these batteries cant even make it thru 1 set of lug nuts on a semi actually takes 2 batteries to complete the Job...where the Milwaukee batteries last the entire job 2 sets of rims removal and install. Also would like to point out the batteries are not as a tight fit on the imapct...loose giving the batteries movement.

Batteries came with 3 lites showing. Charged quickly. Fit my M18 tools perfectly. We'll see how long they last and how many times they cycle. Will update if any problems

For the price , they're amazing, I work commercial construction and use them daily ! They work just as well as the high price ones , which just goes to show , you're buying the brand when you spend hundreds of dollars for 1 battery
