Why Car Batteries Fail in Winter and How to Prevent It

Winter is no friend to your car battery. At Boise Towing Co, we receive more calls for dead batteries during the colder months than at any other time of year. Nothing’s more frustrating than a car that won’t start when it’s freezing outside. But why are batteries more likely to fail in winter? More importantly, what can you do to prevent it? Let’s dive into the reasons behind this common issue and share practical steps to keep your car battery alive through Idaho’s chilly season.

Why Do Car Batteries Struggle in Winter?
When temperatures plummet, car batteries face unique challenges. Here’s why:

Cold Weather Reduces Battery Efficiency
Car batteries rely on chemical reactions to generate the power needed to start your car. When temperatures drop, these reactions slow down, significantly reducing the battery’s ability to perform. At freezing (32°F), a battery’s power decreases by about 20%, and at 0°F, it can lose up to 50%.

Engines Need More Power to Start in the Cold
Cold temperatures thicken your engine oil, making it harder for the engine to turn over. This increased resistance demands more power from your battery—at the very time when your battery is at its weakest.

Higher Power Demands in Winter
In winter, we rely more heavily on features like headlights, heaters, defrosters, and heated seats. This extra load can strain an already struggling battery, especially on shorter trips.

Aging Batteries Are Vulnerable
If your battery is nearing the end of its life (typically 3–5 years), the cold weather can tip it over the edge. Older batteries lose their ability to hold a charge effectively, making them more likely to fail during winter.


How to Spot a Failing Battery
Before your battery leaves you stranded, it often gives warning signs, such as:

Slow Engine Crank: Your engine takes longer to start, especially in the morning.

Dim Lights: Interior or exterior lights that seem dimmer than usual can signal a weak battery.

Warning Lights: A battery or check engine light on your dashboard could indicate trouble.

Corrosion or Swelling: Visible corrosion around battery terminals or a bloated battery case means it’s time for a replacement.

If you notice any of these issues, don’t wait for your car to fail—act now to avoid being stuck in the cold.


Steps to Keep Your Battery Healthy in Winter
While you can’t control the weather, you can take proactive steps to keep your battery in good shape during winter:

1. Test Your Battery Before Cold Weather Hits
Many auto shops and parts stores offer free battery testing. This quick check-up can reveal whether your battery is ready for winter or needs to be replaced.

2. Clean Battery Terminals
Corrosion on the battery terminals can block the flow of electricity. Check your terminals regularly and clean any buildup with a mixture of baking soda and water.

3. Keep the Battery Charged
If your car sits unused for long stretches during winter, its battery may not stay adequately charged. A battery maintainer (also called a trickle charger) can help keep it charged and ready to go.

4. Limit Short Drives
Short trips don’t give your alternator enough time to recharge the battery after starting the engine. Combine errands into fewer, longer trips to help your battery maintain a proper charge.

5. Park in a Garage or Use a Battery Heater
If you have access to a garage, park your car indoors to keep it out of the harsh cold. If outdoor parking is your only option, consider a battery blanket or heater to keep the battery warm and functional.

6. Replace Batteries Near the End of Their Lifespan
Don’t gamble with an old battery in winter. If your battery is over three years old, consider replacing it before it fails unexpectedly.


What to Do if Your Battery Dies
Sometimes, even the best preparation isn’t enough. If your battery dies, Boise Towing Co is here to help with 24/7 roadside assistance, including jump-start services. Here’s what to do if you find yourself with a dead battery:

Prioritize Safety: If you’re on a busy road, turn on your hazard lights and move to a safe location if possible.

Call for Assistance: Contact Boise Towing Co, and we’ll send help your way quickly.

Plan for a New Battery: A dead battery is often a sign that it’s time for a replacement, so make arrangements to get a new one as soon as possible.

Winter in Boise, ID, brings beautiful snow-covered landscapes, but it also introduces hazardous driving conditions that can lead to accidents, breakdowns, and the need for towing services. At Boise Towing Co., we understand the dangers that come with winter driving, and we’re here to help when you need us. However, there are steps you can take to minimize your risk on the road and avoid needing emergency towing. Let’s explore the common hazards of winter driving and some preventative measures you can take to stay safe. Hazards of Winter Driving in Boise Winter weather in Boise can range from light snow to severe ice storms, creating several risks for drivers. Here are the most common hazards: 1. Icy Roads Ice is one of the most dangerous winter driving conditions. It can be difficult to spot, especially black ice, which is nearly invisible on asphalt. Even a small patch of ice can cause your vehicle to lose traction, leading to skidding, sliding, or worse, an accident. 2. Reduced Visibility Snowstorms and fog often reduce visibility on Boise’s roads, making it difficult to see other vehicles, signs, and hazards. Driving in low visibility increases the chances of accidents, and even if you're driving carefully, other drivers may not be. 3. Vehicle Breakdowns Cold temperatures can be hard on your vehicle, leading to breakdowns. Dead batteries, frozen fuel lines, and other mechanical issues are common during Boise's winter months. Being stranded in freezing temperatures is not only inconvenient but dangerous, especially if you’re far from help. 4. Snowdrifts and Deep Snow Even vehicles equipped for snow driving can get stuck in snowdrifts or deep, unplowed roads. Getting stuck in snow is one of the most common reasons people need winter towing services. Preventative Measures to Avoid Trouble on the Road While winter driving always carries risks, there are several things you can do to minimize your chances of needing a tow: 1. Equip Your Vehicle for Winter One of the best ways to stay safe in winter is to ensure your vehicle is properly prepared. Winter tires provide better traction on icy roads, reducing the chances of slipping or skidding. Keep tire chains in your car, especially if you’re driving in rural or mountainous areas where roads may not be well-maintained. Also, make sure your windshield wipers are in good condition and your washer fluid is filled with a winter solution to prevent it from freezing. 2. Slow Down and Drive Defensively Speed is a major factor in winter driving accidents. Slowing down allows you to react to unexpected hazards, like black ice or sudden stops in traffic. Leave plenty of space between you and the vehicle in front of you, and brake gently to avoid skidding. Defensive driving is key to avoiding accidents on slick winter roads. 3. Keep Your Car Well-Maintained Before winter hits, have your vehicle checked by a mechanic to ensure it’s in good working order. This includes checking the battery, brakes, and fluids, as well as ensuring that your heating system works properly. A well-maintained vehicle is less likely to break down in cold weather. 4. Carry an Emergency Kit Despite your best efforts, winter accidents and breakdowns can still happen. Be prepared by carrying an emergency kit in your car. Your kit should include blankets, a flashlight, non-perishable food, water, a first-aid kit, a phone charger, and basic tools like a shovel and ice scraper. These items can keep you safe and comfortable while waiting for help. How Boise Towing Co. Can Help Even with careful planning, winter accidents and breakdowns can happen, and when they do, Boise Towing Co. is here to help. Our experienced drivers are available 24/7 to provide quick, reliable towing services across Boise and the surrounding areas. Whether you’ve been in an accident, slid off the road, or your car simply won’t start, we have the equipment and expertise to get you out of a tough situation and back on the road safely. Winter driving in Boise comes with its fair share of hazards, but with the right preparation and precautions, you can reduce the chances of needing emergency towing.
