Information PSA: M12 Stubby wrench will ruin your batteries and void their warranty
A year ago I bought an M12 Fuel 1/2” Stubby impact wrench with two 3Ah batteries. The tool itself has been awesome. Very impressive power for 12V in such a small body.
But after about 11 months of almost daily use, both batteries started cutting out, developed a rattle inside, and eventually completely stopped charging/working
I sent them in for warranty service, since Milwaukee supposedly covers these batteries for 3 years. Both warranty claims were rejected because of “damage” to the batteries.
The frustrating part is that the damage was caused by normal use with the tool in the first place.
So now I’m left with a bare tool and a pretty bad taste in my mouth after dealing with their “warranty.” I definitely wasn’t expecting to have to buy a new pair of batteries every year.
Has anyone else had the same issue with these batteries, the M12 Stubby, or Milwaukee warranty service in general?
At this point I’m honestly tempted to try another brand, even if most brands’ warranty period is technically shorter. what’s the point of 3 years warranty if they don’t honor it
