At our shop, we see plenty of batteries fail on the first cold mornings even though they started the vehicle without trouble only a few days earlier. Cold Weather Reduces the Battery's Available Power A battery creates electrical energy through a chemical reaction. As temperature drops, that reaction slows down, and the battery cannot deliver current as easily as it can in warm weather. That loss is especially noticeable in a battery that has already lost capacity from age or previous deep discharges ... read more
