Driving with your Battery Light on is not a good idea. If the battery is bad, the alternator is faulty, or the wiring is bad, these can cause the vehicle to lose power and not operate like it normally would. The battery powers essential parts of your car, so it is a must have piece of equipment.

Subsequently, question is, what does it mean when the battery light comes on and off? The battery light indicates a battery charging problem. If the battery light comes on and stays on while you are driving, the most common cause is a broken alternator belt. The reason why your car can operate normally even though the battery light is on is because your car can run off the energy stored in the battery.

In this regard, how long will my car run with the battery light on?

You can drive the car with the battery light on but you will only have on average 15 minutes. After roughly 15 minutes, your car will run out of electrical power and the car will stall.

Can a bad fuse cause the battery light to come on?

Each vehicle comes with a battery light on the dashboard. This light works as a warning in case the battery has a problem. It could be a damaged alternator, corroded wires, fuses, or the battery itself. In such a case, the battery light will then go on.
