Car and Truck Battery Myths and Facts

Car batteries come in a variety of shapes and sizes, from heavy industrial car batteries to car batteries that can be lifted by hand, car battery technology has come a long way over the past century. Car batteries have evolved from large clunky units into much smaller units that can be more easily adapted to car and truck engines. 

At Arnold Motor Supply, we’ve heard it all. Here are some of the more common myths going around about vehicle batteries and electrical systems.

Battery Myth: A Vehicle Battery Will Last Forever

Battery Fact: A battery can–and will–wear out requiring it to be replaced. You should look at your battery as a replaceable part like wiper blades, filters, and brake pads. Car batteries usually only last between three and five years before they need to be replaced. However, car or truck owners who use their vehicles infrequently may find car batteries last anywhere from three to ten years.

Battery Myth: All Batteries Are Basically the Same

Battery Fact: Not all batteries are created equal, and not every battery is interchangeable. This is not just true for the types of batteries but the brands, too. Some battery brands are better for your vehicle than others. High price does not automatically equal high quality. If you have any questions about what brand of battery you should use, ask your professional technician or one of our knowledgeable counter professionals.

Battery Myth: A Short Drive Will Recharge a Spent Battery

Battery Fact: It’s rarely enough time to charge a battery back to a significant enough charge to be useful. Consider getting it recharged–or maybe even replaced–by a professional.

Battery Myth: The Battery is the Only Important Electrical Component

Battery Fact: It’s probably the most important, but it’s not the only electrical component you have to worry about. There are plenty of others like the starter and alternator.
