How Do Employees Test a Battery at AutoZone?

According to a former AutoZone employee, you can either drive the car to the store or take the battery to the store for a staff member to test your battery.

When you take your car to AutoZone, the store has a handheld tester that checks the voltage in the battery. If the battery is okay, the staff will test the alternator to check the current flow.

What Are the Signs That You Need Your Battery Tested?

To determine whether you need your battery tested, here are some of the signs to look out for:

Swollen Battery

If you notice that your battery is swollen more than its usual size, you need to get it tested.

A battery will swell when the alternator has a faulty voltage regulator, or your battery is overcharged.

When your battery has a hydrogen gas build-up that’s more than it can dissipate, it overcharges.

You should test your battery when this happens; otherwise, if the damage worsens, it can’t be reversed, but you’ll have to buy a replacement.

Sudden Slower Start

Ideally, when the temperature drops below 20 degrees, your car battery will have a problem starting.

However, if you notice that the battery has suddenly slowed down, and is not starting under normal temperatures, it’s time to test it.

If the slow battery tests okay and has no problem charging, the AutoZone staff will check whether there is a parasitic drain or discharge.

Your Accessories Work But the Car Doesn’t Start

If your headlights, radio, and other vehicle accessories but the car doesn’t start, it’s time to test the battery.

Normally, your battery should power the car and supply enough power for the lights and accessories.

When this fails, your battery charge might be low; therefore, you should take it to AutoZone for testing.

The Radio Doesn’t Work

When your car ignition is on, the battery powers your radio, headlights, wipers, and other electronic devices.

Therefore, if these don’t work when you start your vehicle, you need to take your battery for testing.

Battery Smell

Ideally, your battery should not have any smell. However, if you detect any odd smells, your battery could be damaged and release acid that can harm other parts of the engine.

This is a sign you should have it tested and even replaced.

Check Engine Light Is On

When your battery has a problem, you might notice that the check engine light is on.

When this happens, you should take the battery to AutoZone for testing to confirm whether your battery is operating correctly.
