Signs My Car’s Battery Is Dying and Needs to Be Replaced

You already know this, but it bears repeating: Your car won’t start if your battery is dead. There are ways you can tell that your car, truck, utility vehicle, or van’s battery is dying. Mark’s Auto Service lists some telltale signs below. If you notice any of these things, bring your vehicle to our shop right away for a battery test. 

Age

The average lifespan of a car battery is 3 to 4 years old. If your battery is older than this, chances are it’s going to die soon if it hasn’t already. Aside from age, you may notice some of the other signs listed in this blog post.

Corroded Battery Terminals

Old or new, it’s always a good idea to check your battery regularly. Look for things like corroded battery terminals. If you combine the corroded terminals with your battery’s age, it could be that the battery is leaking acid and it needs to be replaced.

Cracked or Warped Battery Case

Another telltale sign that your battery is going bad is a cracked or warped battery case. You may also notice bubbling along the sides of the case. This is a sign that the chemical reaction is bad inside the battery.

Dashboard Warning Light

Your automobile has a light on the dashboard that is usually shaped like a car battery. It might also have an ALT or GEN light. If any of these lights turn on, this is a sign that your car’s battery is dying.

Dim Lights

You may also notice a difference in how bright your lights are. This includes all of the lights in your vehicle, not just the headlights. If the lights seem dimmer, your battery is not producing enough power for them to be shining at full brightness.

Electrical Problems

Another sign your car’s battery is dying is problems with the electrical systems in your car. This includes the accessories, such as your power windows and power seat adjustments. These things will slow down or stop working altogether if your car battery is not producing enough power.

Rotten Egg Smell

If you notice a rotten egg smell underneath your hood, it could be the car battery leaking battery acid. Battery acid is sulfuric acid, and burning sulfur smells like rotten eggs. It’s pertinent to note that this could also be a sign that your catalytic converter is dying.

Slow Starts

Finally, slow starts or the inability to start your automobile is definitely a sign of battery trouble. Keep in mind, however, that this can also indicate that your alternator is dead or that you have a problem with the starter.
