Cold weather not only increases engine starting loads, but slows down the rate of electrochemical reactions (hence reducing the performance) of the battery. In addition, modern cars must contend with a greater consumption of electricity, smaller size of battery to save weight and space, and reduced charge rates because of lower idling speeds to save fuel. Tests at CFEC have shown that even if engines start quite quickly it can take half an hour of running to raise the state of charge from 50% to 75% at 20 C, and much longer in winter. Happily, battery manufacturers are aware of the problems and strive continually to improve the battery performance.
