In mobile phones, the battery indicator usually takes the form of a bar graph - the more bars that are showing, the better the battery's state of charge.Ĭomputers may give a signal to users that an internal standby battery needs replacement. In the adjacent picture, the ammeter is marked "Alternator" and the symbols are "C" (charge) and "D" (discharge).īoth ammeters and voltmeters individually or together can be used to assess the operating state of an automobile battery and charging system.Ī battery indicator is a feature of many electronic devices. This indicates whether the battery is being charged or discharged. This can be somewhat misleading as it may be confused for an indicator of a bad battery when in reality it indicates a problem with the vehicle's charging system.Īlternatively, an ammeter may be fitted. Many newer cars no longer offer voltmeters or ammeters instead, these vehicles typically have a light with the outline of an automotive battery on it. This meter is, essentially, a voltmeter but it may also be marked with coloured zones for easy visualization. Some automobiles are fitted with a battery condition meter to monitor the starter battery. 1966 Dodge Charger dashboard, note ammeter marked "Alternator" at top left
