Using this battery charger is very simple.
First, connect the battery and AC power
following the precautions listed under
“OPERATING INSTRUCTIONS”. Then se-
lect the appropriate BATTERY TYPE and
charge rate for your battery. The charger
will then do everything automatically. This
section explains a few details.
CHARGING: If the charger does not
detect a properly connected battery,
the CONNECTED (yellow) LED will not
light. Charging will not begin unless the
CONNECTED LED is on. When charging
begins, the CHARGING LED will be lit.
AUTOMATIC SHUT OFF: When the
SMALL BATTERY or REGULAR BAT-
TERY charge is selected, the charger
is set to perform an automatic charge.
When an automatic charge is performed,
the charger stops charging automatically
after the battery is charged.
ABORTED CHARGE: If charging can’t
be completed normally, charging will be
aborted. When charging is aborted, the
charger’s output is shut off and the digital
display blinks on and off. In that state, the
charger ignores all buttons. To reset from
after an aborted charge, either disconnect
the battery or unplug the charger.
DESULFATION MODE: If a battery is
left discharged for an extended period,
it could become sulfated and not accept
a normal charge. If the charger detects a
sulfated battery, the charger will switch to
a special mode of operation designed for
such batteries. Activation of the special
desulfation mode is indicated by blinking
the CHARGING LED. If successful, nor-
mal 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 be aborted
and the digital display will blink.
COMPLETI ON OF CHARGI NG:
Charge completion is indicated by
the CHARGED (green) LED; when
lit, the charger has stopped charging
and switched to the Maintain Mode of
operation, if the DEEP CYCLE battery
type was selected. For other battery
types, the CHARGED LED comes on
when the battery is charged enough for
MAINTAIN MODE: When the CHARGED
(green) LED is lit, the charger has started
Maintain Mode. This mode of operation is
also known as Float-Mode Monitoring. In
this mode, the charger keeps the battery
fully charged by delivering a small amount
of current, when necessary. The voltage
is maintained at a level determined by the
BATTERY TYPE selected.
NOTE: For charge types other than DEEP
CYCLE, the CHARGED LED might be lit
before Maintain Mode is started.
GENERAL CHARGING NOTES:
The charger is designed to control its
cooling fan for efcient operation. Con-
sequently, it is normal for the fan to start
and stop when maintaining a fully charged
battery. The fan does not run in Tester
If the charge mode is changed after charg-
ing has started (by pressing the CHARGE
START or BATTERY TYPE button), the
charging process will be restarted.
The voltage displayed during charging
will usually be higher than the battery’s
The voltage displayed during charging is
the battery voltage, not the RMS charg-
