Battery Q&A At Mercedes-Benz of Denver

When you need to get somewhere important, the last thing you need to hear when you start your car is the grinding sound that means your battery is dead.

At Mercedes-Benz of Denver, we're dedicated to ensuring you drive with as few problems as possible. So, we've created this page to give you some tips to keep your Mercedes-Benz's battery in top condition.

How Long Do Car Batteries Last?

Because you drive a Mercedes-Benz, we know you believe that you get what you pay for. That holds true for auto batteries.

The typical battery is designed to last up to 4 years with proper maintenance. But if you decide on a cheaper model, you may find it lasting for significantly less time, (usually around 2 years). Conversely, a top shelf battery may last as long as 6 years.

Are There Other Factors That Affect My Battery's Performance?

Of course, the lifespan of your battery also depends on other factors related to how you use your vehicle. Here are some suggestions that can increase your battery's life:

  • Limit short rides
  • Turn off your lights when you exit your vehicle
  • Avoid using your lights and/or electronics when the vehicle's engine is not running
  • Avoid extensive idling
  • Make sure your battery is tightly fastened
  • Make sure your vehicle is serviced regularly

Our team of expert technicians at Mercedes-Benz of Denver can perform the routine diagnostics and maintenance that will help you get the most out of your battery.

What Are The Signs My Battery May Need Replacing?

Here are the warning signs of battery failure:

  • The engine is slow or sluggish to start
  • Check Engine light is on
  • Vehicle makes a clicking sound when you attempt to start it
  • Low battery fluid level
  • Battery appears to be leaking
  • Battery case appears swollen
  • Battery is older than 3 years

If you experience one or more of these symptoms, bring your vehicle to Mercedes-Benz of Denver and have us check your battery.

What About Corrosion?

Corrosion around the battery's terminals can also create trouble for you. You can clean the terminals yourself with an old toothbrush and a solution of baking soda and water. Make sure you clean the terminals with fresh water after you scrub. Also make sure you have disconnected the terminals before attempting your clean-up.

While you cannot keep your battery 100% corrosion-free, there is something you can do to reduce corrosion over time. Either spread a small amount of axle grease on the terminals or use one of the spray-on coatings designed for auto batteries. Ask one of our service technicians to show you how this is done.

Is It The Battery Or The Alternator?

Problems with either the battery or the alternator (which recharges the battery) can cause your vehicle not to start. So, how do you know which is which?

If you jump start your car and it soon stalls and dies, the problem is probably with your alternator. If you jump start and the car runs fine; but when you do shut it off, you can't restart it, then the problem is a dead battery.

Here are some troubleshooting tips that can tell you that you have alternator problems before the car fails to start:

If the interior or dashboard lights tend to dim while the car is running, that's a sign that the alternator isn't working properly.

Do you notice your headlights are brighter when the car is running, but dim whenever you come to a stop? That's another sign that you may have a problem alternator.
