Use 14.4V batteries in a DeWalt 12V Drill?
I have lots of DeWalt 18V XR tools plus two 18V batteries. I have one DeWalt 12V tool, a drill (XTR I think) that works great plus one 12V battery. I happened upon two 14.4 DeWalt XR batteries with charger. The batteries fit the 12V drill (after paring off a small tab). Will I (correct that to "am I likely to) damage my 12V drill by using the 14.4V batteries?
