General Operation
19
Applying AC Power to the ODYSSEY®Battery Portable Charger
During the AC power on startup the blue Self Test mode LED will illuminate. When complete
and if there are no faults, the charger's “System Check OK” indicator will illuminate green
and the charger's solid red charging LED will be ON indicating the charge process is initiated.
Note: If there is a connection, polarity, or battery that is below 2.5 VDC that can not accept
a charge the RED Fault LED will illuminate and the charge process will not start. See page
21 for further troubleshooting details.
If there are no battery faults, the green “System Check” OK LED will illuminate and the
following sequences will proceed:
The red charge mode LED will illuminate indicating the charger has started its multi-stage
charging process as outlined in the Multi-Stage Charging overview section of this manual.
When the charge process is approximately 80% complete, the red charge mode indicator
will turn off and the amber conditioning LED will turn on indicating the conditioning mode.
When the multi-stage charge process is completed you will observe the following: The red
charging LED and the amber conditioning LED will be off and the green Auto Maintain (Energy
Saver Mode) LED will illuminate indicating your batteries are fully charged. In this mode the
charger will only come back on to maintain a full charge when or if the batteries require it
because the charger senses a drop in voltage.
The only LEDs on after the multi-stage charge process is completed are the green “System
Check OK” LED, blue AC power LED and the green Auto Maintain (Energy Saver Mode) LED
and the battery charge monitor showing the battery is full.
Battery Charge Monitor Overview
The Charge Monitor has five green LEDs and one red LED. All five green LEDs will illuminate
when the charger is initially connected as part of the self test. This feature is to provide a
rough indication of the charging process so at a glance you can see what charge level the
battery is at and what remains to complete the charge process 100%.
- First RED LED will light up when battery charge level is at 0-10%
- First GREEN LED will light up when battery charge level is at 10-30%
- Two GREEN LEDs will light up when battery charge level is at 30-50%
- Three GREEN LEDs will light up when battery charge level is at 50-70%
- Four GREEN LEDs will light up when battery charge level is at 70-90%
- Five GREEN LEDs will light up when battery charge level is at 100%
Special Operating Note:
The ODYSSEY®Battery Portable Charger Series includes over temperature protection. If the
operating temperature is out of range, the charger will slow down the charge rate automatically
to maintain its operating temperature. If the temperature is too high the “System Check OK”
LED will flash indicating the charger will stop charging and resume automatically when the
temperature drops to its normal operating range.

Storage & Maintenance
2 Step Integrated Cord Storage
The ODYSSEY®Battery Portable Charger is designed with a built-in cord storage. There
are arrows on the charger ends that direct how the cords are wrapped.
Step 1: The black DC lead should be wrapped first and the alligator clip attached to the
post on the charger end.
Step 2: The red DC lead and AC cord should be wrapped next following the direction of
the arrow. Attach the alligator clip on the red DC lead to the post on the charger end. The
AC cord will end just past the top handle and the hook and loop strap should be used to
secure the cord.

No Blue AC Power LED or Charge Mode Indicator or Battery Charge Monitor
Check for loss of AC power at the 120 VAC outlet. Confirm GFCI (Ground Fault Circuit
Interrupter) has not tripped. Check with a meter or 120 VAC test light that AC power is present
at the end or the extension cord. Reset AC power if it was not present. Confirm all charger
cables are installed with the correct polarity connections at the battery and that all connections
are clean and tight. Wait two minutes while unit performs a self test. If AC power is present
and all connections are correct and LEDs do not illuminate, contact our customer service
department at 1-660-429-2165 from 8:30 am to 5:00 pm Central Time.
Green “System Check OK” Indicator is OFF and a Red Trouble Status LED is ON.
Remove AC power and check the battery. Listed below are typical faults and what can be
done to clear the red battery bank trouble status indicator (reapply AC power after making
any corrections):
Poor battery connections - Make sure all connections are tight and clean
Reverse polarity - Make sure all wiring connections are color coded and connected
properly where (+) = red (–) = black.
Battery too low to charge - With a digital voltmeter make sure the battery is over 2.5 volts
DC (if not have it load tested by your local battery dealer to insure optimum performance.)
High battery voltage input - Check to make sure the battery is a 12V battery.
Battery Appears not to be Charging, Blue AC Power LED, RED Charging and
Battery Charge Monitor LEDs are ON Longer than Expected.
Confirm all charger cables are installed with the correct polarity connections at the battery,
and that all connections are clean and tight.
Check the Quick Application Guide to make sure the charger is not undersized for the battery
you are charging.
With the charger on, using a digital volt meter, read DC voltage across the battery. If the DC
voltage reading increases over time this will serve as a confirmation that the charger is
connected correctly and the charger is properly working. In the event you may have a deeply
discharged battery, it may require two charge cycles.
Note: If it appears the battery voltage is not increasing at all in a reasonable period of time
(30 to 60 minutes). Please call our customer service department at 1-660-429-2165 from
8:30 am to 5:00 pm Central Time.
