Extend the Life of Your Car Battery

Your car battery is designed to last about 3 to 5 years, but the reality is that many people find that they have to change their car battery every 1 to 2 years.

Why is this, and what can you do to prolong your car’s battery life?


Each battery has a lifespan called a “calendar life” and it is completely independent of how many times the battery has been charged or discharged. Once a battery reaches the end of its “calendar life” it will become unusable. However, because of poor maintenance and care, most batteries never reach the end of their “calendar life”.



Simple maintenance and care will increase the life span of your battery. These most basic maintenance should be doing a monthly inspection of the battery terminals to make sure they are clean and corrosion free. Corrosion on the terminals of a battery disrupts the connection between the battery and the car which will lead to your battery not charging properly and your vehicle not working. Many batteries are replaced before the end of their “calendar life” due to too much corrosive build up.


Reducing battery corrosion can be done by simply pouring a small amount of Cola or a DIY anti-corrosion paste (one part water to three parts baking soda) over the corroded areas. The acid in the Cola or the alkaline properties in the DIY anti-corrosion paste will eat the corrosion away.

After the corrosion is gone, use a clean damp rag or sponge to clean up the remaining residue and moisture.
Be sure to let it dry, then rub some petroleum jelly on the terminals to prevent future corrosion.
