When the temperatures drop in Northern Ontario, your vehicle’s battery feels it first. Cold weather puts extra strain on battery performance—making winter the most common season for unexpected vehicle failures.
At NFS Auto Repair, we understand how Sudbury winters can challenge even the best-maintained vehicles. That’s why we’re sharing expert advice to help you protect your battery, reduce cold-weather headaches, and ensure reliable starts every morning.
Why Cold Weather Affects Your Battery
As the weather cools, your battery’s ability to deliver power decreases. Here’s how:
-
Reduced Chemical Activity – Cold temperatures slow the chemical reaction that generates power, which means your battery can struggle to crank the engine.
-
Increased Internal Resistance – Batteries work harder in the cold, requiring more energy just to start your car.
-
Thicker Engine Oil – As oil thickens in low temperatures, your engine demands even more from your battery at startup.
These combined factors often result in dead batteries—especially if your battery is nearing the end of its lifespan.
Expert Winter Battery Care Tips
Fortunately, a few smart habits can go a long way toward preventing issues. Here’s how to keep your battery strong through the coldest months:
Schedule a Winter Battery Inspection
Regular checkups are your best defense. At NFS Auto Repair, we inspect terminals, clean off corrosion, and test your battery’s cold cranking amps to ensure it’s ready for winter.
Park in a Warmer Spot
Whenever possible, park your vehicle in a garage or use a battery blanket. Even a few degrees of warmth can improve battery performance.
Avoid Frequent Short Trips
Starting your vehicle requires a large power draw. However, short drives don’t give the alternator enough time to recharge the battery fully. Instead, combine errands or let the engine run a bit longer when needed.
Invest in a Winter-Ready Battery
If your battery is over three years old or already showing signs of weakness, consider upgrading to a high-quality, cold-climate battery designed to handle Canadian winters.
Turn Off Accessories Before Shutoff
Before turning off your engine, switch off the headlights, defrosters, and other power-draining accessories. This reduces stress on your battery during the next startup.
