    Why is my OzCharge OC-SW121080 Battery Charger showing no charging current?
    • E
      ecohenAug 8, 2025
      If your OzCharge Battery Charger isn't providing any charging current, the battery may be severely sulphated. Consider checking the battery's condition and age. Also, a damaged cell in the battery could be the reason; if rejuvenation isn't successful, the battery should be replaced. Finally, the charger might be in overheat protection mode, so move both the battery and charger to a cooler place.

    Why does my OzCharge OC-SW121080 Battery Charger take so long to charge, and the full light doesn't come on?
    • T
      Todd HowellAug 16, 2025
      If your OzCharge Battery Charger takes a long time to charge and the 'Full' light doesn't illuminate, it could be due to several reasons. First, ensure the charging rate and battery type selection matches the battery requirements. If the battery capacity is too large, or if the battery is defective, it cannot be charged and must be replaced. Also, the battery cannot be charged and must be replaced if the 6-hour soft start timer or the 24-hour bulk charge timer has been reached.

      If your OzCharge Battery Charger has no DC output, check the DC connection between the charger and the battery to ensure there are no short circuits. Make sure the output cables are properly connected to the battery terminals. Also, verify that the crocodile clips or ring terminals are connected with the correct polarity.
