Genuine battery

THIS IS A GENUINE MILWAUKEE BATTERY. I was nervous at first to be honest. But I’m glad I got it because it is a genuine part. Everything about it is great, I use it on my half inch impact and it takes off bolds that a 5.0 wouldn’t budge!

Great battery

After researching batteries for my Milwaukee 3/8 impact wrench I went for this 18v 8.0 it's got more power than the 5.0 and I like that it lasts longer between charges so if your looking for power then this is the battery for you.
