Milwaukee 2604-22 Hammer Drill Arrived with issues.

[Kooshe]

I purchased the Milwaukee 2604-22 kit, Comes with the hammer drill,  2 of the 4 amp hour batteries and a charger. I purchased brand new, So i opened it and i noticed both batteries were dead (single led blinking) and none would turn the chuck, but the led work light came on. I charged one fully and when i tried the drill it was the same deal, Only the work light came on, Battery was full and was not even warm. Frustrated i charged the other only to find the same issue. I had an idea to turn the flywheel while holding the trigger, It did nothing... So i tried turning it and then pressing the trigger, When i did it that was it would run for a brief second before stopping and only the light on, I kept doing it until the drill finally pulled through and started chooching. When i put a load on it it stopped 2 more times and it hasn't again, Only used it in my 9h work shift though so time will tell. So im wondering if anyone has had a similar issue and any ideas on what may be the cause? Would it be the drill, or the batteries due to possibly being dead so long, Any thoughts would be greatly appreciated. (This is my first tool from the red side)
