MAINTAIN MODE
(FLOAT-MODE MONITORING)
When the CHARGED (green) LED is
pulsing, the charger has started maintain
mode. In this mode, the charger keeps the
battery fully charged by delivering a small
current when necessary. If the charger has
to provide its maximum maintain current for
a continuous 12 hour period, it will go into
abort mode (see Aborted Charge section).
This is usually 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.
MAINTAINING A BATTERY
The SE-2352-CA charges and maintains 12
volt batteries, keeping them at full charge.
NOTE: The maintain mode technology
allows you to safely charge and maintain a
healthy battery for extended periods of time.
However, problems with the battery, electrical
problems in the vehicle, improper
connections or other unanticipated conditions
could cause excessive current draws. As
such, occasionally monitoring your battery
and the charging process is required.
MAINTENANCE AND CARE
A minimal amount of care can keep your
battery charger working properly for years.
• Clean the clamps each time you are
nished charging. Wipe off any battery uid
that may have come in contact with the
clamps to prevent corrosion.
• Occasionally cleaning the case of the
charger with a soft cloth will keep the nish
shiny and help prevent corrosion.
• Coil the input and output cords neatly when
storing the charger. This will help prevent
accidental damage to the cords and charger.
• Store the charger unplugged from the AC
power outlet in an upright position.
• Store inside, in a cool, dry place. Do not
store the clamps on the handle, clipped
together, on or around metal, or clipped to
the cables.
TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE REASON/SOLUTION
Charger will not turn
on when properly
connected.
AC outlet is dead.
Poor electrical connection.
Battery is defective.
Check for open fuse or circuit
breaker supplying AC outlet.
Check power cord and extension
cord for loose tting plug.
Have the battery checked.
All three LEDs come
on for 2 seconds, then
turn off.
The charger is plugged into an
AC outlet.
No problem; this is normal.
Engine start does
not work.
Drawing more than 200 amps.
Failure to wait 3 minutes (180
seconds) between cranks.
The charger may be
overheated.
Battery may be severely
discharged.
Crank time varies with the
amount of current drawn. If
cranking draws more than 200
amps, crank time may be less
than 3 seconds.
When the Engine Start LED
blinks, wait 3 minutes of rest
time before the next crank.
The thermal protector may have
tripped and needs a little longer
to reset. Make sure the charger
vents are not blocked. Wait and
try again.
On a severely discharged battery,
use the 35A Boost rate for 10 to 15
minutes, to help assist in cranking.
