PROBLEM
POSSIBLE CAUSE
SOLUTION
The BAD BATTERY
LED is lit.
The battery is sulfated.
Lack of progress is detected and
battery voltage is below 14.2V.
The battery’s initial voltage is
below 12.2V and the total input
is less than 1.5 Ah.
The battery voltage drops to
below 12.2V in Maintain Mode.
The charger is in desulfation mode.
Continue charging for several
hours. If not successful, have the
battery checked.
The battery may be overheated. If
so, allow the battery to cool. The
battery may be too large or have a
short circuit. Have battery checked
or replaced.
The battery capacity is too low,
or the battery is too old. Have it
checked or replaced.
The battery won’t hold a charge.
May be caused by a drain on the
battery or the battery could be bad.
Make sure there are no loads on
the battery. If there are remove
them. If there are none, have the
battery checked or replaced.
Short or no start cycle
when cranking engine.
Drawing more than the Engine
Start Rate.
Failure to wait 3 minutes (180
seconds) between cranks.
Clamps are not making a good
connection.
AC cord and/or extension cord
is loose.
No power at receptacle.
The charger may be
overheated.
Battery may be severely
discharged.
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.
Wait 3 minutes of rest time before
the next crank, to allow the battery
and charger to cool down.
Check for poor connection at
battery and frame.
Check power cord and extension
cord for loose fitting plug.
Check for open fuse or circuit
breaker supplying AC outlet.
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.
On a severely discharged battery,
use the 20A Boost setting for few
minutes, to help assist in cranking.
