Why does the green CHARGED light turn on quickly after connecting my Schumacher Battery Charger?

  Ian BlackwellJul 30, 2025
  If the green CHARGED light illuminates shortly after connecting the battery to your Schumacher Battery Charger, the battery might already be fully charged or recently charged. Try turning on the vehicle's headlights for a few minutes to lower the battery voltage and then attempt charging again. Alternatively, the battery could be faulty (sulfated), so try selecting a lower BATTERY SIZE setting.

  If the 'Connected' light on your Schumacher Battery Charger isn't on, ensure the battery is correctly connected by adjusting the clips. Verify that you've selected the correct voltage (12V or 6V) on the charger, and that the connection to the battery isn't reversed. Press the button to select the correct size and type. If the battery voltage is less than one volt, correct the connection, replace the battery, or try using a manual charger to bring the voltage above 1V.
