• How to Improve Car Battery Life

    Extending your car battery life is a great way to maximize your return on investment on your battery purchase. Car battery life is usually given as a specific number of months. Average warranty periods for car batteries are either 60 months, or five years and 72 months, or six years. Here are some tips on how you can increase the car battery life expectancy of your battery.

    Protect From Temperature Extremes

    Extremes in temperatures are probably the single biggest factor which can decrease average car battery life. Look into buying a battery blanket or thermal insulator. If you live in an area that regularly sees temperatures below freezing, you should look into a thermal blanket that is also a battery heater. Additionally, if you live in this type of environment, you should also purchase an engine block heater. Cold oil doesn’t flow very easily and will add drag to your engine, putting increased strain on your battery, decreasing your car battery life expectancy.


    Proper maintenance is the single best way to increase your car battery life. This means regular corrosion control with baking soda and water. It also means checking the electrolyte level and specific gravity and maintaining proper levels of both.

    Constant Charge Levels

    Once a week you should electrically test your battery. Make sure it is holding a constant 12.5 to 13 volts. Perform a load test and make sure the voltage doesn’t drop below 10.5 volts during the load test.

    The paragraphs above list some methods you can use to increase your car battery life expectancy.
