How much time does it take a car alternator to charge a battery?

It varies depending on how much other electronics you are using on the vehicle at the time. Could take hours. I do not recommend you charge any dead battery with the alternator if you can avoid it. it puts too much of a strain on the alternator and may damage it. Charge a dead battery with a battery charger.

If you have already checked the connections on the battery I would suggest testing the alternator and the battery. If the battery will not take a charge or the alternator will not give a charge you could have similar problems.

Why is your battery light on and Battery meter pegged high on the instrument panel in your 2002 F150 pickup Alternator If so how do you change it out?
I had this problem. The alternator was fine, it was the battery that was bad. The alternator was "pegging" out the indicator bc it was trying to charge the battery, but it wasnt taking charge. Take the battery out and have it checked.

How long to run your car battery after jump charging?
It is best to drive home and put a battery charger on the battery and let it fully charge. Letting it charge with the alternator puts a strain on the alternator and should be avoided if possible. But if you have no charger then you will need to let the engine run for around 30 minutes to charge the battery enough so that it will start the next morning. It will take a couple of hours of driving to fully charge the battery.
If a car's engine light went on battery dropped to 0 and now the car is dead is it the alternator or does it need a new battery?
