VERY GOOD BATTERY!
Just purchased as a backup battery for the Milwaukee Compact Inflator M12 to keep tires inflated in the 2019 Midwest super cold winter. Works very well, provides enough power to inflate two to four vehicles, depending on level of tires deflation. Really like how it has performed thus far. Believe I made a very good purchase.

Long life.
The battery has a longer run time, but the larger size makes the ratchet a bit clumsy and heavier.

Poor Quality Control on M12 4A Hr
Purchased the M12 4.0 A hr. Opened package and could not insert into tool. The black battery housing was not installed over the red plastic guide properly. Misaligned by 1/4". Returned to store and opened up two more M12 4.0 A hr battery with the same misalignment problem.
Fourth battery was finally okay.

Great Battery
If you have the M12 Oscillating tool or the Fuel 5 3/8" M12 circ saw, these batteries are a must. In a drill or impact driver they will last for all day of average usage. They recharge fairly quickly. I have 4 of them and they are great.

M12 awesome battery
This battery provides so much more power and last much longer than the standard battery. I use it in my sds plus rotary drill and it kicks butt, do not have to worry about the battery dying right in the middle of drilling.

Great battery, like how it keeps the tool standing upright
This is a great battery to have as additional to the standard M12 smaller batteries. I really like the fact Milwaukee thought to include the shape of this extended battery in their blow molded plastic tool cases. Well done guys.

lots of added power with little added weight
great for added run time, actually kind of balances the unit out
obviously adds a little more weight, but is an easy trade.

Worth it
It does give you better runtime, but it also makes tools like drills and sawzall's feel better balanced in your hand. Worth the extra clams for sure.

Power of an M18 battery for your M12 tools.
I got this for free with some tools purchased around Father's Day. This battery packs a serious punch. It provides enough power that my M12 Sawzall barely noticed the 1" Crepe Myrtle trunks it was cutting through. It is big though and negates some of the advantages of the compactness of the M12 tools. If you need extra power and running time on your 12V tools and tight spaces aren't a concern, this is the best battery you can get.

Can u use this battery on the heated gear (hoodies,jackets,or hand warmers)
Meechie on Jan 7, 2016
BEST ANSWER: You sure can, but only on 2014 and newer model heated jackets. These newer jackets have an additional zipper on the pocket that allows it to be extended in order to accommodate a larger battery (the 4.0ah XC 12v battery and also the 18v compact 2.0ah.) Just keep in mind that this 4.0ah 12v battery's shape makes it a lot more uncomfortable and cumbersome in the jacket than the 2.0ah or the compact 18v since it has a squared corners. So if you absolutely need the additional runtime, I would recommend the 18v 2.0 red lithium battery with the 18v power source accessory (it's just a USB 12v jacket power adapter) over this 12v 4.0ah XC just for comfort's sake.

Will this battery work in any m12drills?
A shopper on Jan 14, 2017
BEST ANSWER: Yes it will work with any M12 tool. I particularly like that the drills and impact drivers "stand up" when these batteries are attached.
does this battery work in my m12 heated vest?
George Vanderstow on Feb 13, 2017
BEST ANSWER: Yes, the 4ah battery can be used with any of the M12 heated gear
Is this battery TSA compatible (M12 XC)
Rick on May 1, 2016
BEST ANSWER: TSA compatible? Do you mean allowed to take on a plane with you?
Yes, you can get on a plane with that battery. It's only a 48 watt hour battery (12V x 4Ah). All such batteries need to be in carry on luggage, not checked in baggage. Page 2 of the link below specifically shows a portable drill battery (albeit a DeWalt) as an example. Tape over the terminals to protect for short circuiting - or appear to protect from short circuiting. I wouldn't want my equipment confiscated just because someones opinion on what 'protected from short circuiting' is.
From the FAA website:
https://www.faa.gov/about/office_org/headquarters_offices/ash/ash_programs/hazmat/passenger_info/media/Airline_passengers_and_batteries.pdf
Spare lithium metal and lithium ion/polymer batteries are prohibited in checked baggage—this includes external battery packs. “Checked baggage” includes bags checked at the gate or planeside.
Hope that helps!
WHAT IS THE BEST BATTERY FOR YOUR HEATED GEAR ?
Joe on Nov 12, 2015
BEST ANSWER: The best battery depends on the individual. The longest running battery is the M12 4ah battery however that battery is bulky and may feel uncomfortable. The 2 ah battery is slim and considered more ideal given its size but it has 45% less run time than the 4 ah battery
