WARNING: LEAD-ACID BATTERIES
GENERATE GASES WHICH CAN BE
EXPLOSIVE. IF THE CHARGE CYCLE MUST
BE INTERRUPTED, PRESS THE START/STOP
SWITCH TO STOP THE CHARGER, AND
DISCONNECT THE CHARGER POWER
SUPPLY CORD. KEEP SPARKS, FLAME, AND
SMOKING MATERIALS AWAY FROM
BATTERIES.
WARNING: ALWAYS SHIELD EYES WHEN
WORKING NEAR BATTERIES. DO NOT PUT
WRENCHES OR OTHER METAL OBJECTS
ACROSS BATTERY TERMINALS OR BATTERY
TOP. ARCING OR EXPLOSION OF THE
BATTERY CAN RESULT!
4. Monitor ammeter for correct initial charge rate.
Correct initial charge rate should be between
19 and 21 amps. As the battery reaches
approximately 70% of full charge, the charge
rate gradually decreases to a reading
determined by the condition of the batteries as
stated below.
Replaceable Electrolyte Deep Cycle Battery
With healthy batteries, the charging current
will decrease to between 8 and 10 amps and
remain until the charger turns off. As
replaceable electrolyte deep cycle batteries
lose capacity, the charge rate may no longer
decrease to this reading. The charger will still
determine when the batteries are as charged
as they are capable of being and will turn off.
When battery capacity has decreased to
where the charger is no longer able to taper
down to less than 10 amps, or the batteries
will no longer perform as desired, they should
be replaced.
Charger is equipped with a temperature
sensor which automatically turns charger off if
it overheats. Should charger turn off before
batteries are fully charged, check to be sure all
ventilation openings are free from obstruc-
tions. After charger cools down to a safe
temperature, it will automatically restart. If
charger repeatedly overheats, refer to a
qualified service agent.
5. If the charge needs to be stopped temporarily,
press the STOP/START switch to stop the
charger. To resume the charge, press the
STOP/START switch once again.
6. Charger turns off automatically when batteries
are fully charged. Charge time varies with
battery size and depth of discharge. Allow 8
hours for normal charging. Larger batteries
(greater than 225 ampere-hours) or severely
discharged batteries may require up to 18
hours to be properly charged. If the charger
operates up to 18 hours and is unable to fully
charge the batteries, an internal timer turns
the charger off.
7. After the charger has turned off, as indicated
by the ammeter reading to drop to zero (Note:
the RED light will glow until the AC power is
removed), disconnect AC cord.
WARNING: IF THE CHARGE CYCLE MUST
BE INTERRUPTED, FIRST PRESS THE STOP/
START SWITCH, THEN DISCONNECT AC
CORD. KEEP SPARKS, FLAME, AND
SMOKING MATERIALS AWAY FROM
BATTERIES. NO SMOKING.
WARNING: DO NOT LEAVE THE POWER
SUPPLY CORD PLUGGED IN WHILE
UNATTENDED FOR MORE THAN TWO (2)
DAYS. SEVERE OVERCHARGING AND
DAMAGE TO THE BATTERIES MAY RESULT IF
THE CHARGER DOES NOT TURN OFF.
BATTERY STORAGE MAINTENANCE
When the equipment is not in use, charge the
batteries once each week.
TROUBLESHOOTING GUIDE
CAUTION: DO NOT OPERATE THE
CHARGER IF IT IS DAMAGED OR APPEARS
TO BE MALFUNCTIONING. PERSONAL
INJURY OR DAMAGE TO THE CHARGER OR
BATTERIES MAY RESULT. DO NOT
DISASSEMBLE THE CHARGER. TAKE IT TO A
QUALIFIED SERVICE AGENT WHEN SERVICE
OR REPAIR IS REQUIRED. INCORRECT
REASSEMBLY MAY RESULT IN A RISK OF
ELECTRIC SHOCK OR FIRE.
1. If the charger does not turn on, check for one
of the following:
a. Charger is not plugged into a live AC
outlet.
b. Battery connections are wrong (reverse
polarity).
c. Battery is no longer serviceable (voltage
below 2.5 volts for 12 volt system).
2. If the charger turns off before the batteries are
fully charged, it indicates one of the following:
a. The AC power was interrupted during
charge.
b. The battery has been allowed to sulfate.
Charge the battery at least once every
three days when the equipment is lightly
