CHARGING
When charging begins, the yellow/orange
Charging LED will be lit.
COMPLETION OF CHARGING
Charge completion is indicated by the
green Charged/Maintaining LED.
When lit, the charger has stopped
charging and has switched to Maintain
Mode of operation.
ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging is
aborted, the charger’s output is shut off.
The display will show “BAD BAT” and an
error code. See section 16, Troubleshooting
and Error Codes . To reset after an aborted
charge, press the START/STOP button to
turn the charger off.
RECOVERY MODE
(Non-lithium ion batteries only)
If a battery is left discharged for an
extended period of time, it could become
sulfated and not accept a normal
charge. The charger will detect this and
automatically enter Recovery mode.
When this mode is activated, the display
will read “BAD BATT REC”. The display
will revert to normal operation when
normal charging begins after the battery is
recovered. Recovery Mode could take up
to 10 hours. If it fails, charging will abort
and the display will read “BAD BAT F02”.
For more information, see section 16,
Troubleshooting and Error Codes
.
MAINTAIN MODE
When the green Charged/Maintaining
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.
The voltage is maintained at a level
determined by the battery type selected.
GENERAL CHARGING NOTES
• The large chassis-mounted main fan runs,
based on temperatures of the individual
charging boards within the unit and the
total power being supplied by the unit. The
board-mounted fans run, based on the
corresponding board temperature.
• If the charge mode is changed after
charging has started (by pressing the
Battery Voltage or Battery Type button),
the charging process stops and begins
again automatically at the new selection.
• The voltage displayed during charging is
the charging voltage and usually will be
higher than the battery’s resting voltage.
POWER CONTROL
To keep the unit from exceeding its input
current level specification of 10 A, all
charging stations are connected by an I
2
C
(pronounced “i squared c”) communication
bus, and power data is accumulated by
one station communicating with all other
stations. If the power is greater than 1000 W
(this corresponds to an input AC current of
about 10 A), the max current of all stations
is reduced from 12 A to 8 A. After 2 minutes,
if the total power is still above the 1000 W,
the max current of all stations is reduced
to 6 A. Then, after two more minutes, if the
power persists above 1000 W, all stations
are turned off. After any of these power
reductions, excluding shut down, if the total
power drops below 600 W for 1 hour, the
max current in all stations is then increased
back to 12 A.
13. 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
6V and 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
7 and 8.
2. Connect the charger’s power cord to
a 220-240 VAC outlet. Again, be sure
to follow all of the precautions listed
under sections 7 and 8.
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.
TESTER AND CHARGER
When first turned on, the charger operates
only as a tester, not as a charger. To
continue to use it as only a tester, avoid
