Your car battery is one of the most important parts of your car’s electrical system. Without the battery, your car simply isn’t going to work. Your battery works hard, and eventually, it’s going to wear out. So, how long can you expect your battery to last, and how will you know when it needs to be replaced?

When do battery problems happen?

Most cars are equipped with six-cell batteries, equipped with lead and lead-oxide plates that contain diluted sulfuric acid. Battery problems occur when the battery loses some of its capacity due to a process called sulfation. That means that your battery’s sulfuric acid content has dropped to the point where it’s no longer effective, and it won’t start your car. You have a dead battery.

How long do batteries last?

Generally speaking, you can expect your car battery to last anywhere from five to seven years, with a few caveats. First of all, you get far more life out of your battery if you check your battery and drive your car regularly. If you park your car for the winter, for example, you’ll likely need to replace it sooner. That’s because when you’re driving regularly, your battery maintains its charge. If you have a “summer car” that you park during the winter, you should remove the battery and bring it indoors. Simply going out and starting the car from time to time won’t deliver enough of a charge to the battery.

Your mechanic can test your car battery to determine if it’s charging properly, and even give you an idea of how much more life you can reasonably expect from your car battery.

Unless you’re experiencing a really quick drain, you probably don’t have to replace your battery right away. A car battery problem typically worsens over time, so check your battery from time to time, make sure the terminals are clean (you can clean them up yourself just by disconnecting the cables, negative first, and roughing up the terminal posts and the insides of the cables with steel wool), and be alert to any potential battery problems. A dead battery, of course, has to be replaced immediately. A dying battery can be nursed along for a while but should be replaced as soon as is reasonably possible.

Nissan Sentra - Battery will not hold a charge - Jacksonville, Florida
I have to say Brian did a great job. First he came super early which was good for me. He was there to fix my son's car while I was at work. He kept me in the loop and did not take advantage of my son. The problem we thought what was wrong with the car was something else and fixed it on the spot. He did everything to get me a better price. I would give him more stars if I could. Thank you Brian for being a professional and not taken advantage of my son. I would recommend you to anyone. Stay blessed.
