Winter mornings can be tough enough without the added frustration of a car that won’t start. In most cases, the culprit behind those chilly inconveniences is a failing battery. But why does winter take such a toll on car batteries? Understanding the reasons can help you avoid getting stranded and keep your vehicle running reliably through the colder months. Batteries vs. Cold Weather Car batteries work by converting chemical energy into electrical energy to start your vehicle. This chemical reaction depends on a fluid called electrolyte, which allows the movement of charged particles. However, when temperatures drop, the electrolyte thickens, slowing the chemical reaction and reducing the battery’s ability to generate power. At 32°F, a fully charged battery loses about 20% of its capacity. At 0°F, it can lose up to 50%. This means the colder it gets, the harder it is for your battery to provide the power needed to start your car. How Win ... read more
