The 6.0 is highly prone to failure, Google it before you buy.

The 2-pack of the M12 5.0 batteries I bought from Woot last month appear to be genuine Milwaukee and not fake. Came as two individual batteries, each one in the annoying AF customer-maiming plastic blister pack. All of the various markings, stickers, vent locations in the shell, and screw types match genuine Milwaukee batteries. I haven't fully drained to determine capacity, but I did just use one in the inflation tool and after doing all 4 tires the battery still shows as full and it ran at full speed the entire time unlike when I use it with one of the 2.0 batteries.

Same here. I didn't want to believe it until both of my 6.0's failed a bit after a year with infrequent usage at that.

Careful. I got fakes* and returned it. Compare packaging and verify serial number
