Really slow cranking battery this morning.

The 890 CCA battery in the kia ripped the 2.4L over & started in a split second with it well below zero.. and 5W30 synthetic in the engine.. I could tell no perceivable difference from 40F to deep into the negative temps.

The Sonata on the other hand took a double take. Battery is a few years old and the below zero temps are making it show its age. but it did start after a second or two on the 2nd attempt..
