waitley 2 Pack 12V 6A Replacement Battery Compatible with Milwaukee 6.0Ah Power Tools

These function just like a true M12. Haven’t had any issues so far. Quality and construction is great for the price.

These batteries fit perfect and charge quickly. They work well in my new project and look to be durable enough. They are compatible to my Milwaukee drill and I don't have to pull very hard to release. My old battery did't have the base so now my drill stands on it's own and has a longer power duration.

I read a lot of reviews on these before buying them and I’m glad I didn’t let the negative ones steer me away. These batteries fit just like the original ones. I read a lot about cheap plastic, weak clips and they don’t last. Well the don’t last part we will only see but I have a feeling the ones that say they don’t last are the same people who leave their batteries on a charger for weeks at a time because they forget to pull them off. As for the cheap plastic, I disagree. Side by side the clips are exactly the same shape, since and plastic is just as thick as Milwaukee’s. They clip in perfect & hold. I will be buying extras for my 18v from them now. Quality product!

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

Work good so far will have to see how long they last.

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.

The price was great. Battery's charge good and last along time

Good Enough! my only issue is the driver reads the battery as full, or empty… otherwise durable, long lasting, even survived a 7’ drop, recharges fully and quick
