How Cold Weather Affects Car Batteries

Low Temperatures Decrease the Battery’s Life

Low Temperatures Decrease the Battery's Life

Car batteries are chemical factories that produce electricity by converting chemical energy into electrical energy. When temperatures fall, the chemical reaction that generates the electricity slows down, causing the battery to weaken and ultimately fail. In cold weather, the battery loses its strength faster, and it may not have enough power to start the car.

Thickening Motor Oil Makes It Harder for the Battery to Start

Cold temperatures cause the oil to thicken, making it harder for the motor to turn over. When the engine requires more power to start, the battery may not have enough capacity to provide it. It is common for car batteries to fail due to low temperatures and thick oil during winter months.
