Sorry for the slow reply. Thanks KS for the suggestions. As to what batteries, I'm using the 60 v flex.volt 6amp. I have multiple and none of them make a difference. I have a lot of DeWalt stuff going back almost 25 years and I this is the first tool I've ever had go bad. (Or start out bad). I'll take it back in tomorrow and hopefully get it fixed this time.
