How Long Do Car Batteries Last?

Many drivers are interested in learning how long car batteries last so our service team at Mercedes-Benz of St. Louis near Clayton has put together this helpful guide. Typically, a car requires a new battery after three or four years. However, this can vary from car to car. To learn how long car batteries last as well as to find out more specific battery information on your vehicle, trust our service team.

Average Vehicle Battery Life

So how long does a car battery last? This is hard to tell as it depends on a few factors. Some drivers will suggest waiting five or six years to change a car battery while others may say to wait as little as one to two years. In general, we recommend you schedule a battery change every three to four years to avoid any issues.

Much like oil changes and tire service, car battery replacement is a crucial part of routine vehicle maintenance. When you’re at our Ladue service center for a maintenance appointment, have your battery inspected.

Factors That Can Shorten Battery Life

Over time, where you drive and how you drive can ultimately shorten your car battery life. This could lead to you having to replace the battery before the three or four year mark:

• Driving Habits: If you don’t drive much, and tend to leave your vehicle sitting for long periods of time, you could be weakening your car’s battery. During your commute, try taking the longer scenic route, so your car’s battery has more time to charge. Also, make sure you don’t leave the power on when the ignition is off. Leaving an interior light on overnight can easily drain the battery.
• Climate & Location: Driving in a hot climate year-round will weaken your battery more than if you drive in a cooler climate.

What Are the Signs Your Car Battery is Low?

Since the signs are small, you may not notice there’s a battery problem until your car won’t start. Here are some of the signs to look out for:

• Check engine light is on
• The engine is slow to start
• Car lights are dim
• Electric issues (cell phone charger, heated seats, etc. aren’t working)
• Connectors for the battery are corroded
• The battery case looks warped or misshapen

Age is the most obvious sign that your battery is nearing the end of its life. If you’re approaching the three year mark on your current battery, visit our team near Frontenac to have your battery inspected to make sure it’s working properly.
