Why do car batteries die in the winter?

When it comes to living in areas where it gets really cold or even snows during the winter, you may have heard or even dealt with the dreaded dead car battery. It can happen much more often during the winter, and for good reason. So, why exactly do car batteries tend to die in colder weather? 

Funny enough, the real reason is because of the damage that summer can do to a car battery. During high temperatures, the internal plates of the battery can become corroded and it can vaporize the battery juices quickly. This summertime damage can lead to batteries dying more often in the winter because a cold battery has reduced cranking power and low temperatures can thicken motor oil, which can make it harder for the engine to turn over. 

Because of the colder temperatures, it essentially causes the battery to have to work harder in order to power your car. Processes are much difficult with thicker fluids and slower chemical reactions. This can be especially concerning for car batteries that are older than 3 years. 

Car batteries typically only last between 3 to 5 years, so if it has been within that time frame since you last replaced your battery, you should have the battery tested an inspection for charge and condition. Our professionals will test it to see how much life it has left and how much charge it can hold, and can let you know whether or not you may find yourself dealing with dead battery trouble this winter. 

Dealing with a dead battery on the road can definitely be stressful, especially during the winter months. If you have a newer battery, you should be fine. But if it has been a while and your battery is older, there’s no harm in bringing your vehicle into our shop for a check before the winter months arrive.
