Your car battery will eventually wear out, and you’ll usually experience problems like slower starting, dim headlights, and other issues. As your local Hyundai dealership, we’d like you to know a few signs that your battery is failing so you can visit us for a new car battery before the old one dies.

Old Battery

The battery is a vital component but has a relatively short lifespan. On average, a new battery lasts three to five years before it needs replacement. This time can also be shortened due to extreme hot or cold temperatures or problems in the electrical system, like a weakening alternator.

We can connect your battery to our battery tester, and we advise a battery test when your battery is three years old. The battery tester provides detailed information on your battery’s ability to store a charge and recharge. If your battery is healthy, we’ll test it again a year. If your battery is failing, we can replace it while you wait.

Phantom Drain

This spooky name refers to an odd condition where your battery can rapidly drain overnight. When your engine is switched off, the battery supplies power to all your car’s systems. Ordinarily, this doesn’t require a large amount of power as most systems aren’t active. A phantom drain occurs when a system that should be switched off, remains on and continues to draw power.

Two of the most likely causes of this problem are the glove box light ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​and trunk light. These lights should switch off automatically when the relevant lid is closed. If either remains on, they can draw a large amount of power. Our technicians will trace the flow of electricity through your Hyundai to identify the cause of the phantom drain, then we’ll repair it.

Loose Connectors

The battery connects to your electrical system via two cables: a red positive and a black negative. These cables fit tightly onto the battery terminal and are secured in place by strong metal clamps. These clamps ensure electricity flows easily into and out of the battery as needed.

When you’re driving, these cables move slightly. As time passes, the cables can move enough to create a slight gap between the battery and a terminal. Electricity can’t pass through a gap, and this will cut your battery off from the electrical system. We can solve this problem by securely tightening the clamps to ensure they fit tightly again.
