What to Do When Your Car Battery Dies: A Step-by-Step Guide

A dead car battery is one of the most common reasons for unexpected car troubles. It’s frustrating when your car won’t start, especially when you have places to be. But don't worry – we’ve got you covered with a practical guide to troubleshoot and manage a dead battery, from identifying the issue to replacing it, and how WeGotBatteries can make the entire process easier.

In this guide, we’ll take you through the steps to determine whether your battery is the issue, how to test it, and what to do next. We’ll also explain how WeGotBatteries can help you quickly and conveniently get a replacement.

Step 1: Recognize the Symptoms of a Dead Battery

Before jumping to conclusions, it’s important to understand the common signs of a dead or dying battery. Some typical symptoms include:

Your car won’t start: When you turn the key, you may hear nothing, or you might hear a clicking sound.
Dim headlights and dashboard lights: If your headlights appear dimmer than usual or flicker when you try to start the car, it could mean the battery is losing its charge.
Electrical issues: If other electrical components in your car, like the radio or air conditioning, aren’t working properly, it could be a sign of a failing battery.
A swollen or bloated battery: If the battery casing is swollen, it may indicate overcharging or excessive heat, which can cause the battery to fail.

If you notice any of these signs, there’s a good chance that your battery needs attention.

Step 2: Check the Battery’s Connections

Before assuming your battery is dead, check its connections. Loose or corroded battery terminals can prevent the car from starting properly. To inspect the connections:

Turn off your car and ensure it’s in "Park" or "Neutral."
Open the hood and locate the battery.
Check the positive (red) and negative (black) terminals for any visible corrosion, dirt, or looseness.
If you find any corrosion, carefully clean the terminals with a mixture of baking soda and water, using a soft brush. Dry the terminals before reattaching the cables tightly.

If the terminals are fine and there’s still no power, your battery may be dead, and you’ll need to proceed with further testing or replacement.

Step 3: Test the Battery’s Charge

If your car won’t start and the connections seem intact, you should test your battery to determine if it’s dead. You can do this with the following methods:

Method 1: Use a Voltmeter (Multimeter)

A voltmeter or multimeter can help you determine the state of your battery. Here’s how to use it:

Set the voltmeter to DC voltage (most likely 20V).
Attach the positive (red) probe to the positive terminal and the negative (black) probe to the negative terminal.
Read the voltmeter. A healthy battery should show between 12.4V and 12.7V when the car is off. If the reading is below 12.0V, the battery is likely weak or dead.

Method 2: Check the Headlights

If you don’t have a voltmeter, an old-school method is to check the car’s headlights:

Turn on the headlights.
Try starting the car.
If the headlights dim significantly or go out when you try to start the car, it’s a sign that the battery is too weak to power the engine.

Method 3: Jump-Start Your Car

If you’re unsure whether the battery is the issue, try jump-starting the car (refer to our step-by-step guide on jump-starting a car). If the car starts successfully with a jump, it’s almost certainly the battery that needs to be replaced.

Step 4: Assess the Battery’s Condition

If your battery is dead, you’ll need to decide whether to test it further or replace it. Here are some considerations:

Old battery: Car batteries typically last 3 to 5 years. If your battery is older, it’s probably time to replace it.
Swollen battery: If the battery casing is bloated, that’s a clear sign that the battery has reached the end of its life and should be replaced immediately.
Corrosion or leaks: Corrosion around the battery terminals or fluid leaks are indications of an unhealthy battery, which should be replaced.

Step 5: How to Replace Your Car Battery

If you’ve confirmed that the battery is dead and needs to be replaced, you have two main options:

Option 1: DIY Battery Replacement

If you’re comfortable with car maintenance, replacing the battery yourself can save you time and money. Here’s a brief overview of the steps involved:

Turn off the car and ensure it’s in “Park” or “Neutral.”
Remove the old battery: Loosen the clamps on both the positive and negative terminals, and carefully remove them.
Remove the old battery: Depending on your car, the battery may be secured with a bracket. Use the appropriate tools to release and remove the battery.
Install the new battery: Place the new battery in the battery tray, securing it in place. Reconnect the terminals, starting with the positive terminal and then the negative.
Check the connections: Ensure the battery is securely attached, and all connections are tight.
Test the new battery: Start your car and make sure everything is functioning correctly.
