Failure to wait 3 minutes (180
seconds) between cranks.
The battery may be severely
discharged.
The battery is drawing more
than the Engine Start rate.
The charger may be
overheated.
The battery voltage is still
below 10V (for a 12V battery)
or 5V (for a 6V battery) after 2
hours of charging.
(or)
In maintain mode, the output
current is more than 2.0A for
12 hours.
Desulfation was unsuccessful.
Lack of progress is detected
and battery voltage is below
14.2V (for a 12V battery) or
7.1V (for a 6V battery).
The battery's initial voltage
is below 12.2V (for a 12V
battery) or 6.1V (for a 6V

On a severely discharged battery,
use the
for few minutes, to help assist in
cranking.
Crank time varies with the amount
of current drawn. If cranking draws
more than the Engine Start rate,
crank time may be less than 3
seconds.
The thermal protector may have
tripped and needs a little longer to
close. Make sure the charger vents
are not blocked. Wait and try again.
The battery may be defective.
Make sure there are no loads on
the battery. If there are, remove
them. If there are none, have the
