11.4 AUTOMATIC CHARGING MODE
charger is set to perform an automatic charge. When an automatic charge
is performed, the charger switches to the maintain mode (see below)
automatically after the battery is charged.
11.5 ABORTED CHARGE
If charging can not be completed normally, charging will abort. When
charging aborts, the charger's output is shut off and the CONNECTED
(red) LED will blink. In that state, the charger ignores all buttons. To reset
after an aborted charge, either disconnect the battery or unplug the char-
ger.
11.6 DESULFATION MODE
period of time, 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 the CHARGING (yellow) LED blinking.
If successful, normal charging will resume after the battery is desulfated.
The CHARGING (yellow) LED will then stop blinking and stay lit. Desulfation
could take up to 10 hours. If desulfation fails, charging will abort and the
CONNECTED (red) LED will blink.
11.7 COMPLETION OF CHARGE:
CHARGED (green) LED. When lit, the charger has stopped charging and
switched to the Maintain Mode of operation. On Models SSC-1000A and
SSC-1500A, if the DEEP CYCLE battery type is selected, the CHARGED
(green) LED comes on when the battery is charged enough for normal
use.
11.8 MAINTAIN MODE
has started Maintain Mode. 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.
11.9 USING THE BATTERy vOLTAGE TESTER
(MODELS SC-1200A, SSC-1000A AND SSC-1500A ONLy)
Overview
This battery 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
gradually 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, such as by turning
on lights or other accessories for a couple of minutes before you read the
display. Read it a couple of minutes after you have shut the headlights off.
Testing Sequence: There are four basic steps required to test the battery
state of charge:
: When a charge rate is selected, the
: If the battery is left discharged for an extended
Charge completion is indicated by the
: When the CHARGED (green) LED is lit, the charger
