The excessive use of features hungry for power may cause the batteries to die. The extreme cold temperatures cause the batteries to discharge, which makes winter an enhanced threat. In winter, the batteries require more charge to remain functional.

When a battery runs in the heat, the internal corrosion occurs at an accelerated rate. The reason why car batteries die in winter rather than summer is because the battery doesn't require as much power to run the engine when its warm out, so it can run at a lower charge.

Full Answer

Why do car batteries fail in winter?

Left too long without a fresh charge, a battery can discharge beyond recovery. So why do batteries fail in winter? Extreme heat or cold can increase your battery's rate of discharge, making winter a triple-threat to your battery. All that exposure to summer's heat evaporates the water in the electrolyte, increasing sulfation.

They are Working Harder

Batteries do the most job during winter. As the temperatures drop, the oil thickens and requires more power from the car battery to move the oil to the required destinations. It might be explicitly challenging for batteries more than two years old, and they may eventually become powerless and limit their functioning., The batteries might also die.

Struggles Warming Up

Car batteries struggle warming up during winter. Some chemical reactions in a lead battery acid must occur, enabling the battery to hold charge. The cold temperatures slow down the chemical reactions making the battery sluggish in winter.

More Power in Winter

Some features in winter require more power, which might take a toll on the batteries. Due to more extended periods of darkness, the lights need the energy to keep running, and the cold also requires heat to warm car occupants. The excessive use of features hungry for power may cause the batteries to die.

How much power does a car battery lose in cold weather?
