Great battery. Still need something bigger.
I use this battery on my m18 grinder. Its the 6 1/2" one. I can eat this battery up in 15 min or less with a cutting wheel on it. Still a great strong battery

As with all the Milwaukee products I've used, this is another winner! Plenty of power to run my 1 3/4" Rotary Hammer Drill, even a 4" core bit through a 22" thick brick wall (6 bricks), and still have 2 bars left.

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....

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.
