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.
