The charger will automatically adjust the charging current according to the battery’s capacity rating and diagnose and try to recover a sulphated battery. It can recover high resistance caused by sulfation, which a conventional charger is not able to perform, as well as check and indicate a weak or damaged battery. Long term connection will not damage the battery due to the automatic voltage management system which will cut charging when battery is fully charged. Additional features are: ‘ Polarity Reverse Protection. ‘ Short Circuit Protection. ‘ Over Temperature Protection. ‘ Over Current Protection. ‘ Over Voltage Protection.
