The Milwaukee batteries just suck.
I bought an 18V combo package 5 - 6 years ago. Came with two batteries, small circ saw and sawsall. The batteries lasted least than 15 months. I read reviews of the batteries at Amazon most reviews had the same life on their batteries.
Of course I recycled them at HD long ago.
Last year, milwaukee had a recall on the old batteries, they had a metal serial number tab.
They waited years before a recall. That was the only one that could be returned.
Well hello, the batteries died years ago are long gone. How many people would hold onto a battery for 5 - 7 years??
Never, will I buy another battery tool from milwaukee again.
I use Makita or Panasonic battery tools only
