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

These fit the tools fine, have long charge even after being in use and in outside weather on jobs and no signs of degradation. Will buy more if needed.

Work well, and last a pretty long time .almost as long as the milwaukee brand. Haven't heated up like other brands i have tried. All in all a very good alternative to name brand batteries. Sometimes a bit tough to remove just remember to pinch towards the front and they slide out pretty easily.

work perfectly w/ all my m12 tools, no issues. after a few months of use i am very impressed for the price. more comparable batt life to a name brand 4ah, but these preform well for every application i have tried. ive used them in every tool i have, from the m12 vacuum, to drills, drivers, impacts, saws, cutoffs, the rotary tool, and the 12v compact blower. i got these just to use as beater batts in my vacuum, but have ended up using them in my regular rotation for all my tools. they charge normally, and fit well in all my tools. The battery check button/ light is also very handy. would not hesitate to reorder, great value for the price if you just need to get the jobs done and arent bothered by the name on the side of the tool or battery.

Not a bad battery, good life, decent power. As tested on the torque test on youtube it tops out at 278ft lbs on the 1/2 gen 2 stubby milwaukee impact. oem milwaukee 6ah battery did 320ft lbs and the high output milwaukee battery 408 ft lbs. So there is a huge difference in tool power but its still a decent battery for light duty stuff

They are great and very professional looking. They work great as well.

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.

Definitely do not recommend this item. The first battery quit within a few days of use. Got pretty hot but I didn't think much of it. The second battery exploded under the seat of the quad within 3 hours of use. Luckily the quad was parked and the kids got away with minor burns. If possible this product should be banned for safety reasons.

I never trust the rating on batteries. This battery feels good in the hand as far as weight and materials. I tested on a capacity tester and at 3amp draw constant current with a 8.2v cutoff I got 4.62Ah over a 1.5hr period. I opened up the pack and see no name cells and couldn’t find any specific info on these. What I did find off the number of the cells was mostly 2600mah and a 3C rate. That means this pack is really a 5.2Ah pack but in reality you never get 100% so these are really 2300mah cells. Hopefully they are more than 3C rated as that’s less than 10amps output. Overall not a terrible buy for the price but definitely not what they rate it at. I have used this in a few tools and lights.
