Cold weather wreaks havoc on car batteries. According to AAA’s Automotive Research Center, at zero degrees, a car’s battery loses about 60 percent of its strength and at 32 degrees, a battery loses 35 percent of its strength but the engine needs about twice as much power to start. Dead or dying batteries are one of the biggest reasons for roadside assistance calls in the winter.

Car batteries typically last 3-5 years but the lifespan can depend on internal and environmental conditions impacts a battery’s health. With the increase in electronics in vehicles, experts at AAA are noting that battery life is moving closer to 3 years. Accessories can strain and drain car batteries.

There are some warning signs that your battery is dying so to avoid being stuck on the side of the road, be on the look out for these signs:

  • A grinding or clicking sound when you turn on the ignition
  • Your vehicle cranking slowly when attempting to start
  • Your headlights dimming when idling but brighten when the engine is revved

If you think your car battery is dying, turn off all accessories including the heater blower, radio, lights and unplug your charger. Before you turn off your engine, turn off all lights, wipers, heaters  and lights to prevent unnecessary drain on the battery. Avoid using heaters or heated seats  for longer than necessary as they drain the battery and if you are able, park your vehicle in a garage for extra protection.
