Hello. Welcome to Just Answer. Please allow me to assist you. The

battery' light does not have anything to do with a faulty battery. The battery light comes on to indicate that the alternator is not producing sufficient voltage to charge the battery

You either have a loose drive belt that is not llowing the alternator to spin fast enough, or, the alternator has an internal fault.
