A car can typically travel a short distance without an alternator, generally up to 30-60 miles, depending on the battery's condition. Once the alternator fails, the car relies on the battery for electrical power. To extend mileage, switch off non-essential electrical components like the radio and air conditioning. However, it is essential to repair or replace the alternator promptly to avoid being stranded.
