I thought this question was banal. But, so far, everyone is speculating. Let me put it in a more abstract form: Experiment A. 1. Charge a li-ion battery, starting at voltage V1 at temp T1 with amount W1 kWh to voltage V2. 2. Cool it to temp T2. 3. Discharge it at rate A amps, where A is low

I'm sure that if you kept your Leaf inside a warm garage anytime you were not driving it, it's cold weather range would be better than if you park it outside. (However, it may not be as high as it's normal warm weather range, especially if you use the resistive cabin air heater.) Jay
