XC6.0 wont charge
It charged the first time (or i think it did), then after that i get the red/green blink and won't charge.
None of my other M12 batteries have that problem. I'm going to imagine it's a M12 XC6.0 problem.
To top it off, the XC6.0 burned up one of my chargers. I put the battery on the charger, i got the infamous Red/green/red flash and the charger died. I tried the XC6.0 battery on another charger and the same red/green flash, then a solid red/green. I pulled the battery.

Waste of money
Does charge anymore. Have only had this m12 battery for a couple months. Now it just flashes. I thought milwaukee batteries were awesome? Maybe the m18s are but not the m12s

Batteries both won’t charge!
Bought the M12 red lithium for my Milwaukee heated jacket… To my dismay, I had both batteries on the charger for a day a piece only to have to work outside in 8 degree weather (-8 degrees with windchill) to find my batteries weren’t charged. I thought we’ll my truck has a an outlet so I will throw it back on the charger, only to see the led indicator flashing green and red. Haven’t had these very long and they have been stored indoors in a heated garage. Very frustrating and cold lesson to learn… unfortunate and not expected from a Milwaukee brand item.

good battery for the higher powered m12 tools and nice bag
nice not having to change out the typical 2ah batteries twice as frequently compared to the 4ah units. never hurts having more bags. I like to use them for less used tools to make easy to grab "kits" for when they are needed

Using in my heated jacket the 1.0 lasted only like 20 minutes on high the 2.0 about an hour and these 3.0 go for at least 3 hours big improvement over the original 1.0 batterys. My radio would go 7 hours on 2.0 battery but now with the 3.0, 16 hours later it was only down 1 bar. Got the 2 for 1 deal at homedepot.com. for 70$ free ship. Jacket seems to get warmer now too.
