11. OPERATING INSTRUCTIONS
OVERVIEW
Select an unused outlet from the eight
available and connect the battery and
AC power, if necessary, following the
precautions listed under sections 6 and 7.
Then press START. This section explains
a few details.
CHARGING
The CONNECTED (red) LED will not light
continuously until a battery is detected.
If the charger does not detect a properly
connected battery, the CONNECTED LED
will not light. Charging will not begin until
the CONNECTED LED comes on. When
charging begins, the CHARGING (yellow)
LED will be lit.
AUTOMATIC CHARGE
Once the battery type is selected, press
the START button and the charger
automatically selects the charge rate
based on battery size and voltage. When
an automatic charge is complete, the
charger will switch to Maintain Mode and
the CHARGED (green) LED will be lit.
ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging is
aborted, the charger’s output is shut off.The
BAD BATTERY (red) LED will be lit and the
display will read “BAD BAT”. In this case,
the charger ignores all buttons. To reset
after an aborted charge, press the START/
STOP button to turn the charger off.
DESULFATION MODE
If a battery is left discharged for an
extended period of time, it could become
sulfated and not accept a normal charge.
The CHARGING LED will blink when the
special desulfation mode is activated.
When blinking, the charger has switched
to the Desulfation Mode of operation. If
successful, normal charging will resume
after the battery is desulfated. The
CHARGING LED will then stop blinking
and light continuously. Desulfation could
take up to 10 hours. If desulfation fails,
charging will abort, the BAD BATTERY
LED will light and the display will read
“BAD BAT”.
COMPLETION OF CHARGING
Charge completion is indicated by the
CHARGED LED. When lit, the charger
has stopped charging and has switched to
Maintain Mode of operation.
MAINTAIN MODE
When the CHARGED LED is lit, the
charger has started Maintain Mode. This
mode of operation is known as Float Mode
Monitoring. In this mode, the charger keeps
the battery fully charged by delivering a
small current, when necessary. To finish
the charging cycle press the START/STOP
button, and the OFF LED will light.
GENERAL CHARGING NOTES:
• The fan runs whenever one or more
batteries are being charged.
• The voltage displayed during charging is
the charging voltage and usually will be
higher than the battery’s resting voltage.
12. USING THE VOLTMETER TO TEST BATTERY STATE OF CHARGE
OVERVIEW
The charger has a built in voltmeter to
test your battery’s state of charge. The
charger does not have a built in load
tester. As such, a recently charged battery
could have a temporarily high voltage due
to what is known as “surface charge”. The
voltage of such a battery will eventually
drop during the period immediately after
the charging system is disengaged.
Consequently, the tester could display
inconsistent values for such a battery.
For a more accurate reading, the surface
charge should be removed by temporarily
creating a load on the battery by turning
on the lights or other accessories.
The battery tester is only designed to
test 12V batteries. Testing a device with
a rapidly changing voltage could yield
unexpected or inaccurate results.
TESTING SEQUENCE
There are three basic steps required to
test the battery state of charge:
1. Connect the battery charger’s clips
to the battery. Be sure to follow all of
the precautions listed under sections
6 and 7.
2. Connect the charger’s power cord
to a 120 VAC outlet. Again, be sure
to follow all of the precautions listed
under sections 6 and 7.
3. Read the voltage on the digital meter
or press the DISPLAY MODE button
to set the tester to BATTERY % and
read the battery percentage.
