How to Handle a Dead Car Battery
A dead car battery can be a major inconvenience. Tire World Exports offers essential troubleshooting tips to help you get back on the road quickly and safely.
1. Check for Loose or Corroded Connections
The first step in troubleshooting a dead battery is to check the battery terminals for loose or corroded connections. Corrosion can build up on the terminals, preventing a good connection. If you see a white or blue powdery substance, it’s likely corrosion. To clean the terminals, use a mixture of baking soda and water and a wire brush. Ensure the connections are tight and secure before attempting to start the car again.

2. Test the Battery Voltage
Using a multimeter, you can test the voltage of your battery to determine if it’s truly dead or just discharged. A fully charged battery should read around 12.6 volts. If the reading is below 12 volts, your battery is likely discharged. If the reading is significantly lower, it may indicate a dead battery that needs replacement. Knowing the voltage can help you decide the next steps.
3. Jump-Start the Battery
If your battery is discharged, jump-starting it can often provide a temporary solution. You’ll need a set of jumper cables and another vehicle with a working battery. Connect the positive (red) jumper cable to the positive terminal of your dead battery and the other end to the positive terminal of the good battery. Then, connect the negative (black) jumper cable to the negative terminal of the good battery and the other end to an unpainted metal surface on your car (not the negative terminal of the dead battery). Start the working vehicle and let it run for a few minutes, then try starting your car. If it starts, let it run for at least 20 minutes to recharge the battery.
4. Check for Parasitic Drains
If your battery frequently dies, there may be a parasitic drain—an electrical component that continues to draw power even when the car is off. Common culprits include lights, radios, and alarm systems. To check for a parasitic drain, disconnect the negative battery terminal and use a multimeter to measure the current draw. If the draw is higher than normal, start pulling fuses one at a time to identify the faulty circuit. Once identified, have a professional address the issue.
5. Replace the Battery
If your battery is old or damaged, it may need replacement. Car batteries typically last 3-5 years, depending on usage and conditions. If you’ve tried the above steps and your battery still won’t hold a charge, it’s time to replace it. At Tire World Exports, we stock high-quality Swiftex and Lucas batteries, known for their reliability and longevity. Choose a battery that fits your vehicle’s specifications and enjoy peace of mind with a dependable power source.
