  This indicates the Schumacher Automobile Battery Charger is in abort mode, possibly due to a faulty battery or the battery not reaching full charge within 36 hours because it's too large. To resolve this, reset the charger by unplugging it, then re-select the desired battery size and type if needed.

  The battery may already be fully or recently charged, or it could be faulty (sulfated). If the battery is in a vehicle, turn the headlights on for a few minutes to reduce the battery voltage, then try charging again. You might also try a lower BATTERY SIZE selection on your Schumacher Automobile Battery Charger.

  The 'Connected' light may not be on because the battery isn't connected correctly, the polarity is reversed, the wrong voltage is selected (6V instead of 12V), or the battery voltage is too low (less than one volt). Connect or adjust the clips, ensuring correct polarity. Select the correct battery size and type. Correct the connection. If the battery voltage is too low, replace the battery or try using a manual charger to bring it above 1V.
