waitley2 Pack 12V 6A Replacement Battery Compatible with Milwaukee 6.0Ah Power Tools

I have only been using these for just over two months now but they have been working as well as an OEM battery. The battery life is comparable to OEM as is the construction. I will prob be buying two more. Great find and a fraction of the cost.

I have been using them for quite some time and the build quality and battery life is impressive. Battery gauge however is not very accurate. Great batteries if you are running tools that just need an extended battery life such as the M12 tire inflator. I have used them on my m12 fuel impact with no problems as well.

Two batteries were received today. One battery will not charge (I tried three different chargers). The batteries arrived partially charged, per the LED's on the back of the battery, and the LED indicators on the Milwaukee tool. The green "charged" light on the chargers comes on immediately as its being plugged into the charger.Update: waitley customer service reached out and made it right, above and beyond. waitley has me a their customer forever and I purchase a lot of batteries. Thank you waitley's awesome customer support

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

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.

Works just as it should, used it all day for about a week, no issues. Lasts a good while, doesn’t get too hot, charges pretty quick, I haven’t really put the e power to the test yet, but I’m sure I will soon. Fits just like oem

So far, so good. I've had people tell me to steer clear of these aftermarket knock offs, but they seem to be working well after a couple of months of continuous use. Definitely beats the price of oe batteries.

I’ve been very pleased with the quality of these batteries. I honestly can’t tell a difference between these and genuine Milwaukee m12 batteries. I recommend these.
