Preparing Your Car Battery for Fall and Winter
- by Joe Weber - updated on 8/30/2024
The fall and winter seasons will be here soon. As the temperature drops and the seasons begin to change, it's crucial to ensure your car battery is ready to handle the colder weather. A failing battery can leave you stranded in frigid conditions, turning a simple errand into a major inconvenience. To help you stay on the move, here are some practical tips for preparing your car battery for fall and winter.
1. Check the Battery Age
Car batteries typically last between three to five years. If your battery is nearing the end of its lifespan, it may start to show signs of battery failure and it might be time for a replacement. Check the date on your battery to see when it was installed. If it's over three years old, consider having it tested to see if it can handle the demands of the upcoming colder months.
2. Inspect for Corrosion
Corrosion on the battery terminals can impede the flow of electricity, making it harder for your car to start. Inspect the terminals for any white, blue or green crystal-like substance and clean it off using a mixture of baking soda and water. Use a wire brush to scrub the terminals, ensuring a clean connection. You can also use a terminal protection kit to make life a little easier.
3. Test the Battery Voltage
A fully charged car battery should read about 12.4 to 12.7 volts or more. You can test the voltage yourself with a multimeter or have a professional do it. If the reading is low, it may not have enough charge to start your car reliably in cold weather.
4. Ensure a Tight Connection
Loose battery connections can lead to many electrical problems. Make sure the battery terminals are securely tightened. If you notice any loose connections, use a wrench or screwdriver to tighten them but be careful not to over-tighten and damage the terminals.
5. Check the Alternator
Your car's alternator charges the battery while you drive. If the alternator isn't working correctly, your battery won't stay charged. Have your alternator tested to ensure it's functioning properly and delivering the right amount of charge to the battery. When you bring your car over to Batteries Plus for a battery test, we will also test your charging system to ensure that it is in good operating condition.
6. Maintain Proper Fluid Levels
Some car batteries have removable caps that allow you to check the fluid level. If the fluid is low, top it off with distilled water. Never use tap water, as it contains minerals that can damage the battery. If you're unsure how to check the fluid, consult your car's manual or have a professional do it for you.
7. Keep It Warm
Extreme cold can sap your battery's power quickly. If possible, park your car in a garage to keep the battery warmer. If you don't have a garage, consider using a battery blanket—a specially designed insulated wrap that keeps the battery warm for those especially cold days.
8. Regularly Drive Your Car
Cars that sit idle for long periods are more likely to experience battery problems. Make it a point to drive your car regularly. This helps keep the battery charged and prevents it from freezing.
9. Use a Trickle Charger
If you don't drive your car often, a battery maintainer (often called a trickle charger) can keep the battery charged while you are not using it. Trickle chargers deliver a small, steady charge to the battery, ensuring it remains at an optimal level. They are also designed for long-term use, so it is completely safe to leave a battery maintainer connected to the battery all season if it's being stored over the winter.
