Questions & Answers


What is the mah capacity of this battery?

Asked by MiB0602 February 23, 2021


Does this specific battery come with a charger also?

Asked by Vonnie January 21, 2021


how long is the manufacturing warranty

Asked by milwaukeeguy1 January 10, 2021

This battery has a 3 year warranty. I had to have one replaced and Milwaukee was awesome to work with. Free shipping label from milwaukee e service and they sent me a new one.

What is the run time of the m12 6Ah Battery?

Asked by eagle August 19, 2020

It varies depending on the tool. If you’re installing outlets it lasts a week. If you’re installing deck boards it lasts for hours. Definitely a huge improvement over the smaller batteries

Are these pack individually or separately?

Asked by Limit May 14, 2020

those 2 words mean the same thing.

How is this any more compact than a M18 Fuel?

Asked by hulyshotner December 7, 2019

Since all the M12 tools are smaller then comparable M18 tools this battery barely adds any weight or mass to a M12 tool. As the battery base itself offers a rather small footprint. In other words no big deal.

Do these batteries come precharged? If not how long to charge the 6ah battery?

Asked by Luke November 5, 2019

Mine was not, came out of the blister pack with 1 light. Took 3 hours on the standard charger to get me to a full charge that first time

How many ft pounds added

Asked by GAF April 28, 2019

It actually does increase the power in most Tools .......Delivers up to 3X more run-time, 20% more power and 2X more life.......... Don't know if any of these guys answering this question has actually compared the batteries in different tools but they ABSOLUTELY do increase the power even says it in the description with everything from Drills to hacksaws and even my 12 volt impact driver for screws as far as bigger impact drivers not sure if the tool limits the torque which is probably what would happen.

Does this battery deliver more heat to the hoodie as well as a longer runtime than the battery that came with it?

Asked by ItalyBelle November 28, 2017

not more heat, but more that double the runtime

Can this battery be charged using the m12 standard battery charger?

Well worth the cost compared to the smaller batteries. I have had it run my rotary tool(dremel) and speaker a handful of times and it's still at full charge. I use it with my rotary tool to sharpen my saw and I'm amazed how long it's lasted me compared to my other 12 v batteries.

Jumps and Strides
Milwaukee seems to be able to always cram more into a smaller form factor than anybody else. They were able to more than DOUBLE the capacity of their old extended battery, while keeping the exact same form factor. The battery did not get a larger footprint at all, in any way. They managed to upgrade the internal lithium cells in the exact same space while literally doubling battery life. I am thoroughly impressed, and the extended battery life really does show. I used it in several tools and noticed the extended battery life, and also used it in my Milwaukee heated jacket, while uncomfortable, provided a much, much longer operating time than any other battery. Highly recommend to those that use and abuse your M12 tools!

Same GREAT power with LONGER life and .... a stand?
I love all of my Milwaukee tools. Every time I use something from my M12 collection I am pleasantly surprise about the amount of power I get from a lightweight tool. The new XC 6.0AH batteries add 2 great things to my M12 experience. First thing....Obviously extended run times. I notice this on certain tools that just gobble up battery power. For me ..it the HACKZALL. this is the main tool that just seems to not last quite as long as you would like it to last. This battery has changed that. Great run times with the new extended capacity battery. Second thing....This one is not so obvious. It makes a great STAND for my drill and impact gun. Seems like a little thing, but it is very nice added benefit!!

Improved capacity without being bigger
This M12 battery is a big improvement over the XC battery. The original XC battery is rated 32 Wh. This 6.0 AH battery is rated 72 Wh! I could notice any increase in external dimensions at all. See comparison image. It charged up quickly and works as expected in my M12 tools. I like that these batteries allow a drill to be stood up on the battery.

Long Lasting Power
It's dimensions are L = 3.5", W = 2.5", H = 4.5", weight 0.9 lbs. It takes 3 times as long to charge this battery (1.5 hrs) over my 1.5 ah battery but I was able to get more work done per charge, which also means that I'll get more life out of this battery as well. It fit into my M12 charger without tipping over. It's only downfall is that it is harder to pull out from my drill than a smaller battery. Since I love cordless, I have several M12 tools, chargers and batteries that I use because they are more compact and less weight than M18's. I use my M12 drill/driver with a 1.5 ah or 2.0 ah battery when working on small projects. This past summer I helped a friend remove screws from his deck boards so we could replace them with new boards. This involved a lot of pre-drilling and drilling. I began using my drill with my 1.5 ah battery. As I was exchanging my battery for another fully charged one he asked me if I wanted to try his 6.0 ah battery instead. Although it was double the weight of my smaller battery, it ended up lasting the whole project and the additional 0.5 pound did not tire me out. If you need more power and/or long lasting power, this is a great battery for your projects.

More power, more run time, in a small package
I've got both the standard and original XC batteries for the M12 system, which worked well, though I could occasionally have used more power or run time. This battery appears to add considerable power to the already good XC batteries, and does so with nearly identical dimensions and weight. I really haven't noticed any difference in handling between this and the original XC battery, and as you can see from the pictures, there's no noticeable difference in size (I actually mixed the two up, I meant to put the old XC in the middle but it's on the right end). Solid, sturdy, can take some beating, definitely worth it if you find yourself running out of juice with the lower capacity batteries.
