Blown away with the improved performance and runtime of these 12.0 batteries over even the 9.0HD batteries I have.
Holy crap this is an impressive battery! I got a couple of the 9.0 batteries a few years back with the gen 1 Fuel weed trimmer and the early gen 7-1/4" circular saw. Before then all of my M18 batteries were the 4.0AH size. My goal with those 9.0 batteries was to basically double my runtime between charges. Mostly I use them on the Fuel 5" angle grinders in my welding shop. One I keep a metabo or cutoff wheel on all of the time, and the other one I keep a flapper wheel on. If I just have to use a grind rock or a big grinder, I keep my corded grinders handy for that. 90% of the time or more I get by with those 2 M18 Fuel grinders.

Typically I could get through a whole day of welding and fabrication work without changing batteries on either grinder when all I had were the 4.0XC batteries. With the 9.0 batteries these little grinders wake up! It isn't corded performance but it's damn close with the 9.0 batteries. With these new 12.0 batteries it's as good as corded for about 30 minutes or so of actual grinding time. They are at another level over even the 9.0 HD batteries. I was just hoping for longer run time, again, with the bigger battery pack. And again, I was very surprised and happy with the performance improvement of the tools using the 12.0 batteries now.

I purchased the 16" chai saw kit with the one 12.0 battery while there was a promotion to get a free 2nd 12.0 battery, and I jumped all over it. Super glad that I did. Whenever the pole saw becomes available I am hoping they have a 12.0 battery kit for it. With 3 of them you can work non stop and never run out of battery with a rapid charger, even with using the chain saw. How cool is that.

Not sure about this
Have used it in two cordless Hole Hawgs. Both burned up under normal conditions. Don’t know if its the battery or the tool. Any thoughts?

Works great full charge, doesn't make the claims of 150 cuts on chainsaw, falls well short, does good on 7 1/4" circular saw

I have bought this product again.
This battery is a beast ! It lasts forever it seems. I have at least one of each type saw, that Milwaukee makes in the 18V Fuel series. I use the new 12.0 in them all, and cut out the mid day battery swap. Not to mention it’s really a must have for the table and miter saw. One cane with a 9.0 which was ok ..12.0 is better.

These 12.0 High output batteries make your tools run longer. That’s obvious. They also make your tools more powerful under heavy loads. Bigger hammer drills and saws definitely run better than the competitors on these packs. I have 7 and want more.

Use it at work with fuel 5" grinder. Works perfectly. Thinking about buying 7"/9" to see how it does but my guess is it will be great.

Very Impressive Power & Battery Life
I use Milwaukee tools daily, with the majority being the M18 Line. The M18 HD12.0 Battery was a welcome addition to my arsenal, and it definitely has the power I was looking for. I was on a job recently where a homeowner was concerned about a dead tree on their property, and although I didn't have the chainsaw with me, I used my M18 Sawzall with the HD12.0 Battery. I was worried that my Sawzall was going to overheat because it's not the Fuel version, but it actually ran great while I cut the tree down, and trimmed it into smaller pieces. Overall, this took about an hour and a half, constantly cutting the tree in different places(It would have gone much faster if I had my rough tree trim blade on. Out of my M18 5.0's & HO9.0, I'm massively impressed with the HD12.0. Some tools do take more of a toll on the battery life than others, but that's what the speed charger is for. If you don't have one, it will change your battery charging life. I would highly recommend this battery. GET IT! By the way, when I finished cutting the tree down the HD12.0 Still had 2 bars on the battery!

How long does this carge last?
sheran g on Aug 5, 2018
BEST ANSWER: No matter the task or the tool, I get nearly twice the run time out of these than I get with the 9.0 batteries. Wasn't expecting that, but it's been my experience so far. A significant power increase for the tools too, even over the 9.0 batteries.
Is it compatible with my Milwaukee circular saw and surge impact driver?
Mark H on Nov 7, 2018
BEST ANSWER: If they are part of the m18 platform, then yes. I suspect they are.
