The room temperature may not have any meaning insofar as the battery alone is concerned at all. For "optimum" jump starting I would want the engine "warm" and the battery "cold", so room temperature seems to be a reasonable "optimal, in the middle, optimal point.
And, if the battery were to perform best at 140F why waste fuel running the A/C to cool it? Anyone know at which point, hybrid battery temperature, the A/C begins cooling the hybrid battery?

Cool yes (as in 80F or something like that).... not COLD. Try putting your flashlight batteries in the freezer for a couple of hours and then see how bright that flashlight is.
