I am a HVAC Technician. Love a your tools the only thing we don't have yet is your new vaccuum pump it's next.
Great for my heated gear!
All of my power tools so far are M18, I use the M12 batteries for all of my Milwaukee heated gear, they are amazing and you can never have too many batteries right?
Great for small projects
Great batteries but can die rather quickly. They also charge quickly so that is very helpful.
M12 battery.
I use these batteries in my M12 impact driver and the have good power and durability. They work really well for my workbench jobs.
Battery dies after 30 minutes
I got a heated hoodie and got this battery with it and it dies after 30 minutes of being used I really hope i could get help from Milwaukee
M12 CP2.0 appears rugged, reliable and practical.
Liked the performance behaviour so much that I bought three more. The power density seems to be deep - at least deep enough to be very practical. In addition, M12 products can run off of vehicle 12V system, in a pinch.
Great
Long lasting, lightweight, charges quick and very compact to store anywhere

Red and green l.e.d. lights flashing on charge ? After few hours still same. Using on my heating jacket.
M12 batteries
I have only had this item for about 2 weeks and haven’t really had a chance to fully observe all of it’s capabilities. So far though it seems like you would expect a Milwaukee tool to preform.
on charge the red and green both both flash
use on Heated Jacket This is my Second Battery already on ly used a few times
Clips keep braking Tired of taping batterys in
Hold in clips keep braking wish i could buy the black part with the clips on it. If Milwaukee can't make battery that will stay in there tools
I have purchased this item a few times but...
The outer case keeps breaking and I can’t find a replacement that isn’t a offbramd knock off
Great battery, but why the packaging thats so hard to get in
This is a great battery for the tool, but the packaging is really overkill. Very hard to get into.
