A battery is normally rated at 75°F (25°C), the normal standard temperature. But when the temperature decreases, the battery capacity also decreases due to reduced molecular "activity" in the electrolyte. A 1,000 amp-hours (Ah) battery at room temperature has its capacity reduced to 70% at -4°F (-20°C), giving 700 Ah maximum capacity.
