Interesting. I decided to test that drill a bit and i put it to 3/8 strength and it worked, i held the drill and clutch got into effect. If i tried 4/8 or higher, it didnt, drill simply stopped. Then i recharged it just out of curiosity and tested it again. Put it to 8/8 ( highest setting ) and i couldnt hold it. Since i didnt use that drill much but batteries obviously discharged anyway, it got me thinking that while drill maybe has less torque, it still has enough to hurt my fingers when i am trying to hold it, but more importantly, obviously batteries are self discharging very quickly.
This is kind of strange. First of all, i put battery pack out of the drill when storing for this exact reason, to make sure there is no connections that could discharge battery. Also i tested those 12 batteries and their charge is very close to eachother, under load and when not under load. To my understanding for that fast self discharge, 1 or more batteries must have a lot lower charge then the rest. Here this is not the case, so why is that battery pack doing that ? It was maybe 2 or 3 weeks and power went down considerably.
