Plenty of power
These are definitely big and full of power. I ran this on my fuel cric and it seemed to give it better performance in addition to the run time. i use it on my bench top saws as well but I don't suggest it for the drills or impact drivers given the weight is a bit much for those and unnecessary.

Runs cool and lasts all day!
I use this battery mainly in my new Fuel Sawzall on my farm. It is perfect to trim off overhanging branches that try to take me off the tractor seat while brush hogging, cut down small trees, and deal with smaller blown-down trees that are obstructing trails.

This battery makes the front end of my Sawzall lighter, due to the counterbalance effect of it being near my hand on the back end of the tool, making it very easy to use one hand to reach up and cut branches off.

A good pruning blade is a must-have for this task. They really zip though branches! As is good eye protection when cutting above your head.

Having and using my new Fuel Sawzall and this 12.0 H.O. battery is far handier and safer than getting my gas chainsaw out all the time, especially when trying to make cuts above your head.

With this combination I can plug along all day, and get a lot of progress made. Makes a big difference on hot summer days.

I got this with the chainsaw kit I purchase when it was first released. I have used it in the chainsaw with great success as well as my miter saw. I used the battery over three days cutting down several poplar stands on my property. Battery was down to one bar after several hours of use over the three days. really good battery, just got some high output 3.0s looking for forward to running those. I do wish the battery fit in my transfer pump but alas....

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.

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.

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.
Will Milwaukee 48-11-1812 M18 REDLITHIUM HIGH OUTPUT HD12.0 Battery Pack fit and still work?

Milwaukee 0880-20 M18 18V Lithium-Ion 2 Gallon Wet/Dry Vacuum (Tool Only)
Milwaukee 0880-20 M18 18V Lithium-Ion 2 Gallon Wet/Dry Vacuum (Tool Only)
BEST ANSWER: The 0880-20 was re-designed in 2017 in order to allow larger packs (including the HD12.0) to fit. The HD12.0 will not fit in the original design of the 0880-20. You can tell at a quick glance which version of the vacuum you have - if your hose is stored under the lid, it is the newer design. If it is stored on the side, it would be the original design.
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.
Will it charge on any charger?
CWMJR on Aug 17, 2018
BEST ANSWER: This battery will charge on any charger. For best performance, we recommend using the new Milwaukee Super Charger, part number 48-59-1811. It will charge a HD12.0 battery in approximately an hour.
