Richard,
I applaud you. You have taken the initiative to learn even if it meant discovering you had misconceptions. I have learned from apprentices and have given them verbal credit. Any person who thinks he or she has all the answers is a fool. You were curious about the performance of a battery in cold weather. Ironicaly a battery in service is adversally affected by cold weather. As temperature decreases,battery performance decreases. They are directly proportional. The common car battery is taken for granted when in fact a whole 3 semester hour course would be required to explain them. CAR54 where are you?
