2 Pack 12V 6A Replacement Battery Compatible with Milwaukee 12V Power Tools (Not Made in Milwaukee)

Fantastic product! So far, and I’m two months into using this. The power is excellent, the build is robust and certainly on part with the name brand. You basically can’t tell the difference in terms of the construction and material ruggedness. The only issue is will the power output stand the test of time. Let’s see! From a price point I got two for the price the other is asking for one. I consider this a wonderful purchase.

To start out these batteries fit well in all the tools I’ve tried it in on the m12 platform and have run every tool I’ve tested them with seemingly identical. One thing Milwaukee is known for is the quality and durability of their batteries. Also the technology in the tools and batteries to communicate with each other to avoid damage to either the battery or tool. They last long for the workday and last a years before failing. That being said I remain concerned putting one of these on certain hi drain tools such as m12 circ saw, sawzall, and running them really hard for long periods of time. I have multiple led lights on the m12 platform that I like to use these to rotate on.. I think I have 10 or more Milwaukee m12 genuine batteries: 3-6ah, 3-4ah, and 4-2ah (or 1.5ah). I have at least 10 m12 tools including the usb charger. I’ve had these for 5+ years and 90% of them still perform very well with heavy use. I’ve run hundreds of thousands of 3”screws in my m12 fuel 3rd gen.. If you’re still reading I’m guessing you’re well into the platform and likely know im right and there’s a reason there are so many red fans. In that case I’d tell you just order a couple. You spend more on bits and blades.. Obviously if cost isn’t a factor I’d say go buy genuine batteries in a tool set deal from Home Depot because they are super well made and dependable.. and I have no regrets doing that for work. The rubber on the bottom is a bit better on the genuine ones and will likely last longer. I’ve only had these in rotation for about 3 months but so far money well spent. They run in my impact just fine running 3” deck screws, these are a great price, have a battery life indicator button on the back, and are hard to tell a difference in any tool so far. I will try and update if they fail. I bought a single 6ah then I got a 2 pack a little after. If your just getting into the m12 platform I’d say go buy a drill set that comes with batteries when Home Depot has Christmas deals or “special buy of the day”but never pay full price for their batteries alone.. They are great but priced insanely too high.

Great and great price I've had thousands of dollars miwaukee tools for over 10 years now and never really though 3rd party batteries would be good but these have exceeded my standards not sure if they exactly spec on amp hours but seem to last longer than my milwaukee 4.0 m12's been using them everyday for the last month doing mechanical work in the oil field and are holding up good.

UPDATE: I usually wait a while before leaving a review, if at all, just to make sure I've used the product and can be honest. This is an update to my original review with added stars because customer support / seller has replaced both batteries at no charge to honer the warranty. I never asked for replacements because it was the risk I took not buying genuine. A+ customer support. ORIGINAL REVIEW: Plastic clips molded to the sides where it attaches to the tool are oversized, brittle and break off just by sliding into the tool. I don't slam in the batteries, I don't throw of drop my tools. I make my living using them and take care of every tool I own. I have plumbing tools from the 1980s that look and feel like new still and they get used weekly. The other issue is that these batteries get hot quickly and don't charge fully after 4 or 5 times. In other works the battery cells burn out after 4 or 5 charge cycles. I will just pay more for the genuine Milwaukee batteries

Love that it has a battery level indicator works well with all my m12 tools great power hopefully the clips last as most my other battery brands have not

Obviously not as strong as the high outputs I’m used to, however for the price you pay and for what you get I’d buy again if needed. Going forward I’ll only be buying high output originals. Had these knock off for 6-7 months and use them everyday for cabinet work (drills, impacts, saws, nailers) they work just fine and still charge well and last a decent amount of time.

First look at these batteries they look and feel great they fit in my m12 insider ratchet snug. Only time will tell if the clips hold up to heavy use. Will update to a 5 star if I am able to get a month on job with no issue. (Update) THESE BATTERIES ARE FANTASTIC! I have put them through all the stresses of a construction site and all they have done is impress me! For the price these can not be beat!

Brought these for my son which is a lineman and he loves them. He said they hold the charge very well.
