How to Keep Your Car Battery Healthy During the Late Winter Months

Devin Kelley • February 19, 2025

As we finish up February, winter continues to challenge your car battery. Cold temperatures slow down the chemical reactions inside your battery, making it harder for your engine to start. If your battery is already weak, the lingering winter chill can push it over the edge, leaving you stranded at the worst time. At All-Star, we want to help you keep your vehicle running smoothly as winter starts winding down. Here are some essential tips to maintain your car battery’s health through the final stretch of the season.


1. Test Your Battery Before Spring Arrives

If your battery has been struggling throughout the winter, now is the time to get it tested before transitioning into warmer months. A professional battery test can determine if your battery is holding a charge properly. 


2. Keep Your Battery Clean

Winter conditions bring snow, slush, and road salt, all of which can lead to dirt and corrosion on your battery. Corrosion on the terminals can prevent a proper connection, making it harder for your car to start. Clean the battery terminals with a mixture of baking soda and water using a wire brush to ensure a strong connection.


3. Park in a Garage or Insulated Area

Even as winter starts winding down, February can still bring freezing temperatures. Parking your car in a garage or a sheltered area can keep your battery from being exposed to extreme cold, helping to prolong its life.


4. Limit Short Trips

Short trips don’t give your battery enough time to recharge fully. In winter, try to combine errands into longer drives to allow your battery to regain its charge. If your car sits for long periods, consider using a battery maintainer to keep it charged and ready to go.


5. Turn Off Accessories Before Starting Your Car

Before starting your car, turn off lights, the heater, defroster, and the radio. These accessories draw power from the battery, and in cold weather, every bit of energy counts when trying to start your vehicle.


6. Consider a Battery Warmer

If your area continues to experience deep freezes in February, a battery warmer can help maintain a proper operating temperature. These warmers wrap around your battery and keep it from getting too cold overnight, making it easier to start in the morning.


7. Replace an Old or Weak Battery

If your battery is nearing the end of its lifespan or has been struggling to start your car all winter, replacing it before the next cold snap is the best preventative measure. A new battery ensures reliability and prevents unexpected breakdowns in the cold.
