How Does Cold Weather Affect A Cars Battery? (Can It Kill It?)
Can cold weather cause your car battery to die? Absolutely! The car battery doesn’t handle cold weather well. Why does cold weather affect the car battery? For starters, it creates a reduced capacity. When the temperature hits 32 degrees, the capacity of the battery drops 20-percent. It drops even further as the temperature goes down.
Additionally, the recharge rate while driving becomes diminished. You will need to drive longer and further to get the same charge as during normal temperatures. The load also becomes more increased as you use the heater, defroster, heated steering wheel, and windshield wipers, creating a larger strain on the battery.
Finally, oil in the engine becomes thicker during cold temperatures. As it starts to solidify, turning the engine over becomes more challenging, requiring more power from the battery. Forcing it to work this hard when the capacity is lowered can often cause the battery to die.
