I returned one of the combo kits to HD but kept the other (I needed to get some work done last night). Went to Lowe's and the guy there opened up a box for me. We plugged it in and put the battery on. The light blinked a few times, and went to steady red (indicating full charge). When I checked the power indicator on the battery, 2 out of the 3 green LEDs lit up, indicating it was between 50-70% fully charged. So, now I have checked 3 units and they are all acting the same way.
I'm thinking I should return my set and go with another brand. I really would hate to do that, but I'm not sure what other recourse I have? The service center is an hour away from me, and of course, they are not open on the weekend. The idea of taking a day off, driving 2 hours round trip, over a brand new $300 combo kit is not very appealing to me. This is not the DeWalt experience I was expecting.
If you think it is operator error, please feel free to suggest something. But, it is pretty idiot proof. Plug charger in, insert battery, watch the lights.
