Your car is a complex machine with many moving parts. The battery is one of the parts that causes issues frequently. Both extreme heat and extreme cold can contribute to problems. The team at Reynolds Collision Center is here to explain.

Let's start with cold weather. It makes the oil in your car thicker, which makes it harder for it to move through your engine. Your battery, which is producing less power in the cold, then has to work harder to turn the engine over. Your alternator will also need more time to recharge your battery during cold weather.

Heat is considered harder on car batteries. Why? It can cause evaporation, which will damage the internal structure of your battery. It can also cause key metal parts underneath your hood to corrode, which causes a multitude of problems. Extreme heat can even lead to your battery overcharging.
