Will a car stay running if you disconnect the battery?

I think my car’s battery is the root of some problems I’ve been experiencing. But to test whether it’s the battery, I want to try running the car even with the battery disconnected. Is this possible?

Sorry to hear that you’re having car troubles!
Yes, a car will stay running if you disconnect the battery. This is because the alternator should provide sufficient energy to power the vehicle even when the battery is removed. However, if the vehicle dies, you have a faulty alternator that should be replaced.
If you’re experiencing more car issues than usual, it may be a good time to consider buying additional car insurance. Not only will this protect you from breakdowns or accidents that are a result but it can also save you money on your annual premium! The easiest way to do this is to download the Jerry super app.
