What to do if the red Bad Battery LED is lit and yellow/orange Charging LED is flashing on my Craftsman CMXCESM14144?

  If the red Bad Battery LED is lit and the yellow/orange Charging LED is flashing, it could mean the battery voltage is too low after charging (below 10V for a 12V battery or 5V for a 6V battery) or, in maintain mode, the output current exceeds 1.5A for 12 hours, indicating unsuccessful desulfation. The battery may be defective. Ensure no loads are on the battery; if present, remove them. If there are no loads, have the battery checked or replaced.

  The red Bad Battery LED being lit indicates a few potential issues. It could mean the battery is sulfated, there's a lack of charging progress and the battery voltage is low (below 14.2V for a 12V battery or 7.1V for a 6V battery), the battery’s initial voltage is low (below 12.2V for a 12V battery or 6.1V for a 6V battery) with low total input, or the battery voltage drops too low in Maintain Mode. The charger may be in desulfation mode, so continue charging it for several hours. If that doesn't work, have the battery checked. Also check for overheating and allow to cool if needed. The battery may be too large, have a short circuit, have low capacity, be too old, or won’t hold a charge. Make sure there are no loads on the battery. If there are, remove them. If there are none, have the bat...
