What Should I Do If My Car Battery Dies After a Jumpstart?
We've all been there before: you get in your car, start it up, and suddenly, the engine sputters and dies. After trying to restart it a couple of times, you realize your battery is dead. You don't panic, though, because you have jumper cables and a good samaritan to help you out. After a few minutes, the jumpstart works, the engine roars to life, and you're on your way. But then, just as you’re driving, your car stalls again. The battery dies once more, and you're left wondering: what do I do now?

1. Understanding Why Your Car Battery Dies After a Jumpstart
Before we jump into the solutions, it's essential to understand why your battery might have died again after the jumpstart. Car batteries don’t just fail randomly—they fail for reasons that are often linked to the health of your battery or other car systems. Here are a few reasons why this might happen:
- Bad Battery: If your battery is old or damaged, a jumpstart might only temporarily revive it, but it won’t hold the charge. A weak battery simply won’t be able to sustain your car’s electrical needs for long.
- Faulty Alternator: The alternator is responsible for charging the battery while the engine runs. If your alternator is malfunctioning, it won’t charge the battery properly, leading to repeated battery failure even after a jumpstart.
- Corroded Battery Terminals: Sometimes, it’s not the battery that’s the problem, but the connection. Corroded terminals can prevent the battery from properly connecting to the electrical system, causing charging issues.
2. What To Do When Your Car Battery Dies After a Jumpstart
If your car’s battery dies after a jumpstart, here are some essential steps to take:

2.1. Check Your Battery and Alternator
The first step is to check whether your battery or alternator is the issue. Here's how to do that:
- Test the Battery: If your car still starts up after a jumpstart, but dies after a short time, it's more likely that the battery is the problem. You can test your car battery using a voltmeter or take it to an auto parts store for a free battery test.
- Test the Alternator: If your car starts and runs temporarily but shuts down again after a short while, it's possible your alternator isn’t charging the battery properly. A mechanic can easily test the alternator to determine if it’s failing. If the alternator is not working, your car will eventually stop running even after a jumpstart.
2.2. Inspect the Battery Terminals
Another quick fix is inspecting your battery terminals. Corrosion can easily build up around the terminals, preventing a solid connection between your battery and the car’s electrical system. If you notice any greenish-blue corrosion around the terminals, you can clean them with a mixture of baking soda and water. Make sure the connections are tight, and the cables are securely attached.
2.3. Attempt Another Jumpstart
If you haven’t already, try jumping your car again. This time, keep the jumper cables on a little longer to make sure your battery gets enough charge to hold. However, if this doesn’t solve the issue, it’s time to move on to other options.
3. What If the Jumpstart Doesn’t Work? Call for Help!
If the jumpstart doesn’t work the second time around or if you’re still stuck with a dead battery, it’s best to call in professional help. A towing company or roadside assistance service can help in multiple ways:
- Roadside Assistance: Many car insurance policies or stand-alone programs offer roadside assistance, which can include jumpstarts, towing, and even getting a new battery installed right on the spot.
- Towing Services: If you don’t have roadside assistance, or if your car is too far from home, a reliable towing company like Rescue & Towing can help transport your car to the nearest mechanic or auto repair shop. In some cases, they can also take your car to a location where you can get a new battery installed.
4. What to Expect from a Professional Mechanic
Once you get your car to a mechanic, here’s what you can expect them to do:
- Battery Replacement: If your battery is the culprit, the mechanic will replace it with a new one. They may also recommend a new battery if yours is too old, even if it wasn’t the main issue.
- Alternator Repair or Replacement: If the alternator is the problem, the mechanic will test it and determine if it needs repair or replacement. This is a critical repair because if the alternator isn’t working properly, it will continue to drain your car’s battery.
- Electrical System Diagnosis: In some cases, there could be underlying issues with the car’s electrical system that cause battery problems. The mechanic will perform a comprehensive diagnosis to pinpoint the issue and fix it accordingly.
5. Preventing Future Battery Issues
While your car may be up and running again after a jumpstart or repair, it’s essential to take measures to prevent future battery issues:
- Regular Battery Maintenance: Make sure to check your battery regularly for corrosion or wear. Keeping the terminals clean and tight will prevent many common issues.
- Check the Alternator: Have the alternator checked regularly to make sure it's working properly. The alternator is key to keeping your battery charged, so addressing problems early can save you money in the long run.
- Keep Your Battery Charged: Try to avoid leaving your car unused for long periods, as this can cause the battery to lose its charge. Consider investing in a trickle charger if your car sits for extended periods of time.
6. Conclusion
If your car battery dies after a jumpstart, it can be frustrating and even dangerous if you’re stranded.
