How do Extreme Weather Temperatures Affect Car Batteries?

If you live in an area that enjoys four seasons, you probably know all to well how extreme temperatures affect your car battery’s performance. Many people consider very cold temperatures to be the most destructive for a battery. While it does cause problems, heat is actually more detrimental.

Motor oil thickens in very cold temperatures. As a result, it creates more work for the battery and starter relay to turn the engine over and get the system charging. That means more work and energy. Add to that the longer times that lights, heater, and wipers are operating, and you have still more pull on the electrical system. Heat, however, causes liquids to evaporate, and the batteries electrolytes can be easily drained. When that happens, it causes the battery to overheat.

If you’re confronted with extreme cold in the winter, keeping your battery charged will help offset some of the energy it needs. Make sure that fluids are properly topped off in the summer. Routine fall and spring maintenance is recommended.
