Review: 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.
Review: Great batteries for the price. No need in wasting a bunch of money on normal milwaukees Color is great. Haven't gotten hot. Good design. Batteries last long enough very compatible

## Questions & Answers

**Q: Are these batteries work well with m12 milwaukee brand? do they hold the charge? do they fit and release well on the tools or charger?**
A: They work perfect on the charger. They hold a charge and work well in the tools.
Runtime is 36% longer than my Milwaukee 4.0 battery.
Fit & Release needs work. Waitley told me on Aug 25th, 2020 they will fix these issues:
Fits my 2453-20 Impact Drill. Slightly loose. Release is good.
Falls out of my 2530-20 Circular Saw. Reviewer John has similar experience.
Considerable difficulty inserting and removing from my 2504-20 1/2" Drill.
Reviewer Jack Z and Tom P have similar experiences.

**Q: Do the tabs that lock battery in place break easy?**
A: I have not had the locks break but I have had them come loose while using the tool, I have to continue reinstalling the battery.

**Q: Will this battery work in heated vest**
A: I don’t know how much power a vest use. This 6 Amps 12 Volts battery produce 72 Watts. You need to know how many watts per hour the vest you have in mind use.
My use is for a Milwaukee converted to a sharpening grinder to sharp tungsten electrodes for TIG welding. The batteries are working nicely.

**Q: How many batteiries come in this pack? I know it says 2 batteries, but I heard someone only received 1 battery when their package came.**
A: It comes with two batteries

I’ve been very happy with how long these batteries last. The only negative is they don’t stay clipped in the tool as well.
