Batteries hate winter. Cold temperatures slow down the chemical reaction inside, dropping your battery’s capacity by nearly 50% at 0°F (-18°C). That’s why dead batteries happen most on frosty mornings. Keep your cables in the cabin overnight—cold cables are stiff and less effective.
If you regularly drive short distances (under 15 minutes), your alternator never fully recharges the battery. A weekly highway cruise for 30 minutes keeps things healthy. Think of it as a spa day for your car’s electrical system.
