What to Do When Your Car Battery Dies

1. Get a Jump Start

1. Get a Jump Start

If your car battery dies while you’re on the road, you may be able to jump-start it using jumper cables and another vehicle’s battery. Connect the cables to both batteries in the correct order, and then start the working vehicle to charge the dead battery. It’s a temporary solution, so make sure to head to a mechanic right away.

2. Replace the Battery

If you can’t get your car started with a jump, chances are your battery is dead and needs to be replaced. You can buy a new battery at an auto parts store and install it yourself if you’re comfortable with basic car maintenance. Otherwise, bring your car to a mechanic to have the battery replaced.

3. Check the Alternator

Sometimes a dead battery is a symptom of a larger problem with the car’s electrical system, such as a faulty alternator. If your battery keeps dying, even after it’s been charged or replaced, it’s likely that the alternator needs to be repaired or replaced. Bring your car to a mechanic to diagnose the issue.

This includes checking the battery’s connections and cleaning them regularly, as well as getting the battery tested and replaced if necessary. Don’t forget to also maintain your car’s alternator and electrical system to prevent future issues.

  • Regular check-ups with a mechanic can go a long way in preventing car troubles, including dead batteries.
  • It’s a good idea to keep jumper cables and a portable battery charger in your car in case of emergencies.

What You Need

Before attempting to jumpstart your car, you will need a few things:

  • A set of jumper cables
  • Another vehicle with a working battery
  • Your car with a dead battery

Getting Started

First, park the car with the working battery next to your dead car, making sure the two vehicles are close enough for the jumper cables to reach both batteries.

Next, turn off both vehicles and make sure that they are in park or neutral with the parking brake on. Then, connect the positive (+) cable to the positive terminal on your dead battery and the other end of the positive cable to the positive terminal on the working battery.

After that, connect the negative (-) cable to the negative terminal on the working battery and the other end of the negative cable to an unpainted metal surface on your car, like a bolt or bracket. Do not attach the negative cable to the negative terminal on your dead battery, as this could result in a dangerous spark.

Starting Your Car

Start the car with the working battery and let it run for a few minutes. Then, try to start your car. If it doesn’t start, wait a few more minutes and try again. Once your car has started, let it run for a few more minutes to allow the alternator to recharge the battery.

Final Steps

Once your car is up and running, detach the jumper cables in the reverse order that they were connected, starting with the negative cable attached to your car. Be careful not to touch the metal parts of the cables together as this could cause a dangerous spark.

Finally, leave your car running for at least 20 minutes to allow the battery to recharge before turning it off again. Better yet, take it for a drive to fully recharge the battery.

Replace Your Battery

Step 1: Purchase a New Battery

If your car battery is dead and cannot be recharged, it is time to replace it. Purchase a new battery that fits the specifications for your vehicle from an auto parts store.

Step 2: Turn Off the Car

Step 2: Turn Off the Car

Before replacing the battery, turn off the car engine and make sure all accessories are turned off as well. This will prevent any electrical discharge or injury.

Step 3: Remove the Old Battery

Locate the battery in your car engine. Disconnect the negative cable terminal first by loosening the terminal and then pulling it away from the battery. Do the same for the positive cable terminal. Remove the battery hold-down clamp and lift the old battery out of the engine compartment.

Step 4: Clean the Battery Tray

Wipe the battery tray with a clean cloth to remove any dirt or debris. This will ensure good contact between the new battery and the engine compartment.

Step 5: Install the New Battery

  • Do not touch the battery terminals with your hands or any metal objects as this can cause a shock or damage the battery.
  • Dispose of the old battery properly by taking it to a recycling center or auto parts store.

Preventative Measures

1. Regular Maintenance

Regular maintenance is key to preventing a dead car battery. It’s recommended to have your battery checked and serviced every six months or 10,000 miles, whichever comes first. This includes cleaning the battery terminals, testing the voltage, and topping off the electrolyte fluid if necessary.

The battery cables should also be inspected for corrosion, and replaced if necessary. In addition, make sure your alternator is functioning properly, as a faulty alternator can also cause your battery to die.

2. Avoid Overuse of Electronics

The more electronics you use in your car, the faster your battery will drain. It’s best to avoid overuse of electronics such as the radio, air conditioning, and charging your phone if you’re driving short distances or have a weak battery.

Also, make sure to turn off any electronics before turning off your car to avoid draining the battery unnecessarily.

3. Driving Your Car Regularly

3. Driving Your Car Regularly

Driving your car regularly can help prevent a dead battery. If your car is sitting unused for long periods of time, the battery can gradually lose its charge. To keep it charged, it’s recommended to drive your car at least once a week for 30 minutes or more, and to avoid short trips.

If you know your car will be unused for an extended period of time, it’s best to disconnect the battery or use a battery maintainer to keep it charged.

4. Invest in a High-Quality Battery

Investing in a high-quality battery can also help prevent a dead battery. While they may be more expensive, high-quality batteries are built to last longer and have a higher resistance to corrosion and damage.

Make sure to research and consult with a professional to find the right battery for your vehicle’s make and model.
