Have you made allowance for the battery plates being closer together the colder the battery is...?
I don't think the difference would be significant. However, as I understand things, both are right in some sense of the word. A COLD battery will produce less current when it is drawn on because the chemical reactions are temperature dependent. A HOT battery will have a high internal resistance and will therefore have a larger voltage drop when current is drawn from it. The battery will operate best, somewhere in the middle.... not at the two extremes.
