USING YOUR BATTERY CHARGER
OVERVIEW
Using the SpeedCharge battery charger
is very simple. First, connect the battery
and AC power following the precautions
listed under “OPERATING INSTRUC-
TIONS”. Then select the appropriate
BATTERY TYPE and CHARGE RATE
for your battery. The SpeedCharge will
then do everything automatically. This
section explains a few details.
CHARGING:
If the charger does not
detect a properly connected battery, the
CHECK (red) LED will light continuously
until such a battery is detected. Charg-
ing will not begin while the CHECK light
is on. When charging begins, the
CHARGING LED will be lit.
AUTOMATIC SHUT OFF:
When the 2A
or 30A
10A charge rate 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 red
CHECK LED and digital LED blink on
and off (at opposite times). In that state,
the SpeedCharge 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 spe-
cial desulfation mode is indicated by
blinking the CHARGING LED. If suc-
cessful, normal charging will resume af-
ter 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 CHECK
(red) LED will blink.
30A CHARGE RATE:
When set to
30A
10A, the unit will charge the
battery for a few minutes at 10A. The
charger will determine whether to
increase the current to 30A, based on
factors including the battery voltage and
type selected. If the current is increased
from 10A to 30A, the 30A
10A LED will
change from yellow to orange. Eventu-
ally, the current will decrease from 30A
back down to 10A and the LED will
change from orange back to yellow. The
charge current may be increased to 30A
and decreased back down to 10A
several times during the charging
process. After the battery has been
charged enough for the display to
indicate 77%, the current will not be
increased to 30A.
COMPLETION OF CHARGING:
Charge
completion is indicated by the
CHARGED (green) LED; when lit, the
charger has stopped charging and
switched to the Maintain Mode of
operation.
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 current,
when necessary. The voltage is main-
tained at a level determined by the
BATTERY TYPE selected.
