When the temperature drops, so does your car battery’s reliability. Many drivers have experienced the frustration of a dead battery on a cold winter morning. But why does this happen, and more importantly, what can you do to prevent it?
Why Car Batteries Fail in Winter
Cold weather puts extra stress on your vehicle’s battery for a few reasons:
Batteries lose strength in the cold. They simply don’t produce as much power when the temperature drops.
Your car needs more energy to start. Cold engines are harder to crank, and at the same time you’re probably using the heater, defroster, and lights—all of which drain the battery.
Old batteries give out faster. A battery that seemed fine in summer may show its weakness once the chill sets in.
Warning Signs to Watch For
Your engine cranks slowly before starting
Lights look dimmer than usual
You need to “pump the gas” to keep it running when you start up
Your battery is 3 years old (or older)
If you notice these signs, it might be time to check or replace your battery.
Easy Ways to Prevent Battery Trouble
Have it tested. You can test it yourself with a simple battery tester or have a shop check it in just a few minutes.
Keep it clean. A quick wipe of the terminals can help electricity flow better.
Park smart. If you can, park in a garage or somewhere sheltered from the wind.
Drive longer trips. Short drives don’t give your battery enough time to recharge.
Consider a charger. If you don’t drive often in the winter, a small battery charger can keep it topped up.
