With a deep freeze expected this weekend, subzero temperatures will test the hardiest of car batteries, so be prepared, says AAA Northeast.
Slow engine cranking, dim headlights, and illuminated battery/charging warning lights are sure signs a car battery may be weak and may need replacement, especially if it’s more than five years old.
AAA Northeast offers some tips to make sure your battery starts in the season’s coldest weather:
- Clean/inspect the battery terminals for corrosion and loose or cracked connections. Clean corrosion with a 50/50 baking soda and water solution.
- If you haven’t driven much recently, drive your car for 30 minutes before the deep freeze to keep the charge.
- Before starting your engine in the cold, turn off your lights and accessories. If the car doesn’t start within 10 – 15 seconds, stop, take a moment, then try again.
- Idling is unnecessary. Once you secure your seat belt and adjust the heat, drive gently until you feel the heat coming from the climate control.
Electric-car owners may find that their EV’s range may be reduced up to 50% in cold weather. To maximize the range:
- Warm the battery while it’s plugged in, so it’ll accept a charge more efficiently. During cold weather preconditioning also increases your EV range because the battery will be warmed up to its best operating temperature.
- Warm the vehicle cabin while the car is plugged in. Depending on the vehicle, the seat heaters may be more efficient than the car heater.
- Drive at moderate speeds.
If battery issues continue, AAA Northeast offers a mobile battery service to test and replace your battery on the spot. Use our online request system for easy and convenient roadside service: AAA.com/GetMoving or through the AAA app.
