A bad alternator will result in a discharged (dead) battery and cause a vehicle to not start or run. Alternators are designed to maintain a battery's charge, not to recharge a dead battery. Your alternator's job is to maintain a consistent charge on your battery. Draining your car's battery is not advised.

What happens if you drive with a broken alternator?
Driving around with a bad alternator isn't a smart idea; as damaged or broken alternators can cause a wide range of problems. They can interfere with your car's electrical features, make it harder to start the engine, and even cause the battery to drain entirely, leaving you with an utterly unresponsive vehicle.
How serious is a broken alternator?
A bad alternator won't sufficiently charge the battery while the engine is running, causing the charge to deplete faster than usual. One way to test whether the issue is battery- or alternator-related is to jumpstart the car. If you jumpstart your car and it stays running, your battery may need replacing soon.
How does a car act when the alternator is going out?
When the alternator is failing, there might not be enough power in the spark plugs to keep the engine alive, which can cause it to stall for no reason while running, or to have trouble starting. Ignore this symptom, and your car eventually won't start at all.
What kills an alternator?
Running in full charge mode continuously can kill an alternator, so trying to have your new alternator try and charge your dead battery can result in immediate alternator failure.
How much does it cost to fix the alternator?
When your car starts having electrical problems, it's a sign you need an alternator replacement. Considering the price of a new alternator as well as labor, you should expect to spend anywhere between $500 and $1,000 to get a new one for your vehicle.
Can you jumpstart a car with a bad alternator?
While jumpstarting a vehicle with a bad alternator may technically be possible, do not leave jumper cables connected between vehicles longer than necessary as it can result in damage to sensitive electronics.
Do alternators fail suddenly?
When your alternator begins to fail it can cause a variety of different electrical problems in your car, and eventually cause a breakdown. Alternators can go bad suddenly, or slowly over time.
Will a bad alternator drain a battery?
A corroded or defective alternator diode will faultily continue charging the circuit even when the car off. This, in turn, will drain your car battery and cause the car not to start.
How long will a car run without alternator?
It entirely depends on the capacity of the car battery. If the battery does not have a full charge, the vehicle may run from 5 to 30 minutes. The runtime will increase in case of a fully charged battery.
How do you tell if it's your battery or alternator?
If your engine won't turn over or takes far longer than usual, it's time to grab the jumper cables and attempt a jump-start. If your engine starts and stays running but won't start again later, it's likely a battery problem. If your vehicle immediately stalls, it's probably a bad alternator.
What noise does a bad alternator make?
A common sound made by failing alternators is a very high pitched whining noise that you'll hear when the engine is running. When the RMPs increase, such as when you accelerate, you'll hear the noise get higher in pitch as the pulley spins faster.
How long does it take for a bad alternator to drain a battery?
In this situation, the battery could last as little as 30 minutes. If you are lucky and could get up to two hours. Note: In case you have to start the car without an alternator, don't turn off the engine once you're going. Starting the car flattens the battery down quickly.
What is the average life of an alternator?
The average longevity of an alternator is seven years or about 150,000 miles. Several factors can impact the lifespan of your alternator, including the quality of the part, the overall condition of the vehicle, and how many electronics are being used.
Can alternator be repaired?
Without them, some of the repairs cannot be done. The most popular and easy repair to do, in most cases, is replacing the voltage regulator. If you know how to take off and return the alternator, you will certainly know how to change a voltage regulator.
