The performance of a car battery depends on its treatment and the driving conditions. Temperature has a specific effect on durability and can alter chemical reactions inside the battery.
High temperatures of over 130 degrees Fahrenheit can cause resistance problems, as melting can occur. Heat increases evaporation rate and can cause loss of water from the electrolytes, allowing the positive plate grids to corrode.
In areas of extremely low temperatures, special batteries may be necessary, with extra insulation so as not to damage components. At -77 degrees Fahrenheit, electrolytes will freeze and the cold can affect the chemical reaction inside the battery, increasing internal resistance.
Keep a stored battery fully charged, to stop freezing sulfation and further discharge. Place the battery in a dry area that is well ventilated.
