Generally, a car battery can last between three and five years, but there are many factors that can influence the longevity of a battery. Beginning with the quality of the battery, some batteries are just built better and are designed to last longer. Other factors include the climate you live in, your driving habits, and how often you drive the vehicle.
Additionally, if you are intentional about keeping your vehicle maintained, like regular battery checks, cleaning your battery terminals and connectors, your battery will last longer. If your battery has been in use for three or more years, you’ll want to bring it in to have it checked with a voltmeter to verify its health. If you have had it for five years or longer, consider replacing it to avoid being stranded with a dead battery.
