As the days grow shorter and the temperatures drop, fall and winter bring beautiful scenery, cozy evenings, and unfortunately, a bit of extra strain on your vehicle. Cold weather can take a toll on your car's electrical system, especially the battery and alternator, which are vital for keeping your vehicle running smoothly. At Old Town Auto Service, we want to make sure your car is ready for the challenges that come with colder weather. Let’s talk about why it's so important to take care of your battery and alternator this time of year.
Why Cold Weather Affects Your Car Battery
Cold weather can have a significant impact on your car’s battery. When temperatures drop, the chemical reactions inside the battery slow down, reducing its capacity to hold a charge. A car battery that performs well in the summer may suddenly struggle to start your engine in the winter. Additionally, using more electricity for heaters, defrosters, and lights in the darker months puts extra strain on your battery.
Here are some reasons your battery might be more vulnerable during colder months:
- Reduced capacity: Cold temperatures can cut a battery’s power by up to 50%. What worked fine at 70°F may struggle at 20°F.
- Increased power demand: Your vehicle needs more power to start in the cold, as oil becomes thicker, making the engine harder to crank.
- Extra accessory use: With headlights, seat warmers, and defrosters working overtime, your battery has to support all these extra functions.
Here are some signs of a Weak or Failing Battery:
- Electrical Issues: If you experience dim interior and headlights, power windows and locks might not function correctly, that maybe a sign of a weak battery
- Starting Issues: If you are having difficulty starting engine, clicking sound when trying to start, that maybe a sign of a failing battery
- Corrosion: If you see corrosion around battery terminal it may be a sign of a failing
The Role of the Alternator in Cold Weather
While your battery gets most of the attention, the alternator is equally important in ensuring your car can start and stay running. The alternator’s job is to recharge the battery after it starts your vehicle and to power the electrical systems while the engine is running.
In colder months, the alternator works harder because of the additional power required by heating systems, wipers, and defrosters. If the alternator isn’t in top shape, it can struggle to recharge the battery and keep everything running smoothly.
Signs of alternator trouble:
- Dim headlights: If your headlights are flickering or dimming, especially when using other accessories, it could be a sign that your alternator is failing.
- Battery warning light: If this light comes on, your alternator might not be charging the battery properly.
- Strange noises: A failing alternator might produce whining or grinding noises.
Winterizing Your Car’s Electrical System
The good news is that there are some simple steps you can take to ensure your battery and alternator are in good shape before the cold sets in.
- Get your battery tested: Before the cold weather hits, have your battery checked to ensure it has enough charge. Batteries over three years old are more prone to failure in the winter months.
- Inspect your alternator: Have your alternator inspected to ensure it's providing enough power to the battery. Our technicians at Old Town Auto Service can test its output and make sure it’s running properly.
- Clean the terminals: Corrosion on battery terminals can reduce the efficiency of your battery and alternator. Cleaning them before winter can help maintain a strong connection.
- Replace old batteries: If your battery is showing signs of weakness, such as slow engine starts, consider replacing it before the winter months to avoid an inconvenient breakdown.
