Hello, It sounds like you may have faulty voltage regulator that may not be allowing the alternator to charge the battery properly. The voltage regulator is a unit that regulates the charging of the battery by the alternator and maintaining a certain amperage while the engine runs. Unfortunately, even with a properly functioning alternator, the voltage regulator may cause your car not to charge properly. I would suggest having a professional from YourMechanic come to your location to inspect your charging system.
