Why Pothole Season is a Suspension Killer

If your car has ever struggled to start on a cold winter morning, your battery probably took the blame—and for good reason. Winter is one of the toughest seasons on your vehicle’s battery, and understanding why can help you avoid getting stranded when you least expect it. Cold Weather Slows Battery Power Your car battery relies on chemical reactions to produce power. When temperatures drop, those reactions slow down, reducing the battery’s ability to deliver the energy needed to start your engine. In fact, a battery can lose up to 30–50% of its starting power in freezing conditions. At the same time, cold weather causes engine oil to thicken, which makes the engine harder to turn over. That means your battery has to work even harder just to get the car started. Batteries Weaken Over Time Most car batteries last between three and five years. If your battery is already a few years old, winter often exposes its weaknesses. A battery that worked “just fine” in summer may suddenly struggle once cold temperatures arrive. That’s why many battery failures happen in winter—even though the damage often started long before the cold set in. Short Trips Make It Worse Winter driving often means shorter trips, which don’t give your battery enough time to fully recharge. Between cold starts, headlights, heated seats, defrosters, and other electrical accessories, your battery may be working overtime without getting a chance to recover. Over time, this constant drain can lead to a dead or weakened battery. Corrosion and Connections Matter Cold weather can also make existing battery issues worse. Corroded terminals or loose connections reduce the flow of electricity, making it harder for your battery to do its job. In winter, even a small amount of resistance can mean the difference between starting your car and calling for a jump. How to Protect Your Battery This Winter The best way to avoid battery trouble is with a simple battery test. A quick inspection can measure your battery’s strength, check for corrosion, and ensure your charging system is working properly. If your battery is nearing the end of its lifespan, replacing it before winter hits can save you from an inconvenient breakdown.
