Test Car Battery Levels For Winter
In case the battery is low, you can attempt charging it, but make sure the battery holds a charge.
Low temperatures automatically reduces battery cranking power, and that means you want to make sure the battery is fully charged during cold weather.
Check battery terminals for any corrosion. When there is corrosion around the terminals, clean them thoroughly.
Check battery fluid level. If the fluid is low, you can add distilled water.
Generally if the battery is more than 5 years old and shows signs of weakness, All American Chevrolet of Killeen suggests replacing the battery with a new one.
