Quick Charge SCX - Manual (Page 11)

The cycle ends with Er
showing, and a
green/yellow flashing
LED. An incomplete cycle.
The batteries did not
reach minimum voltage
requirements, and the
charger bulk timed out. The batteries are too big
for the charger.
The batteries have
defective cells, and
cannot make minimum
voltage.
NOTE: An occasional
short cycle is not a
problem. Just unplug the
charger and plug back in
to complete the cycle.
