Charger DW9116 Batteries DC9096

I just bought a new DC825KA I have several Dewalt 18V tools, So I have a DeWalt charger DW9116 in my garage....I charged one of my new batteries from my new kit in this charger...no problem, 1hr later new battery is charged. I charge the second battery from my new kit using the charger from the kit, 1hr later, light is flashing Hot Cold pack delay and the battery is very hot....temp in my neck of the woods is around 70 degrees today. Also wondering, when I run the impact driver I see sparks in the rear vents....don't recall seeing that with my buddies 825 the other day. Wondering if I should return the kit and exchange it for another one.
