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