BATTERY CHARGER (SN 030000199 TO
030000225 & SN 030000236 TO PRESENT)

LEAD ACID BATTERIES MAY GENERATE EXPLOSIVE HYDROGEN GAS DURING
NORMAL OPERATION. KEEP SPARKS, FLAMES, AND SMOKING MATERIALS
AWAY FROM BATTERIES. PROVIDE ADEQUATE VENTILATION DURING CHARG-
ING. NEVER CHARGE A FROZEN BATTERY. STUDY ALL BATTERY MANUFACTUR-
ERS' SPECIFIC PRECAUTIONS SUCH AS RECOMMENDED RATES OF CHARGE AND
REMOVING OR NOT REMOVING CELL CAPS WHILE CHARGING.

RISK OF ELECTRIC SHOCK. CONNECT CHARGER POWER CORD TO AN OUTLET
THAT HAS BEEN PROPERLY INSTALLED AND GROUNDED IN ACCORDANCE
WITH ALL LOC AL CODES AND ORDINANCES. A GROUNDED OUTLET IS
REQUIRED TO REDUCE RISK OF ELECTRIC SHOCK - DO NOT USE GROUND
ADAPTERS OR MODIFY PLUG. DO NOT TOUCH UNINSULATED PORTION OF OUT-
PUT CONNECTOR OR UNINSULATED BATTERY TERMINAL. DISCONNECT THE AC
SUPPLY BEFORE MAKING OR BREAKING THE CONNECTIONS TO THE BATTERY
WHILE CHARGING. DO NOT OPEN OR DISASSEMBLE CHARGER. DO NOT OPER-
ATE CHARGER IF THE AC SUPPLY CORD IS DAMAGED OR IF THE CHARGER HAS
RECEIVED A SHARP BLOW, BEEN DROPPED, OR OTHERWISE DAMAGED IN ANY
WAY - REFER ALL REPAIR WORK TO QUALIFIED PERSONNEL. NOT FOR USE BY
CHILDREN.

Operating Instructions

ALWAYS USE A GROUNDED OUTLET. WHEN USING AN EXTENSION CORD,
AVOID EXCESSIVE VOLTAGE DROPS BY USING A GROUNDED 3-WIRE 12 AWG
CORD.

The charger will automatically turn on and go through a
short self-test. All LED’s will flash in an up-down
sequence for two seconds. The yellow "Charging" LED
will turn on and a trickle current will be applied until a
minimum voltage is reached.

Once a minimum battery voltage of 2 volts per cell is
detected, the charger will enter the constant-current
charging stage and the yellow LED will remain on. The
length of charge time will vary by input voltage and
ambient temperature.

When the green "Charged" LED turns on, the batteries
are completely charged. The charger may now be
unplugged from AC power. If left plugged in, the char-
ger will automatically restart a complete charge cycle if
battery voltage drops below a minimum voltage or 30
days have elapsed.

If a fault occurred during charging, the red "Fault" LED
will flash with a code corresponding to the error.

Maintenance Instructions

For flooded lead-acid batteries, regularly check water
levels of each battery cell after charging and add dis-
tilled water as required to level specified by battery
manufacturer. Follow the safety instructions recom-
mended by the battery manufacturer.

Make sure charger connections to battery terminals are
tight and clean.

Do not expose charger to oil or to direct heavy water
spraying when cleaning vehicle.

Battery Charger Fault Codes

If a fault occurred during charging, the red "Fault" LED will
flash with a code corresponding to the error. Refer to the table
following for the flash codes and their removal.

Table 3-6. Battery Charger Fault Codes

Flash(s)

Fault

Fault Removal

Battery Voltage
High

Auto-recover - Indicates a high battery pack voltage

Battery Voltage
Low

Auto-recover - Indicates either a battery pack failure,
battery pack not connected to charger or battery volts
per cell is less than 0.5 VDC. Check the battery pack and
connections

Charge



time-out

Indicates the batteries did not charge in the allowed
time. This could occur if the batteries are a larger
capacity than the algorithm is intended for or if the
batteries are damaged old or in poor condition.

Check Battery

Indicates the batteries could not be trickle charged up
to the minimum voltage per cell level required for the
charge to be started.

Over Temperature Auto-recover - Indicates charger has shut down due to

high internal temperature

QuiQ Fault

Indicates that the battery will not accept charge
current, or an internal fault has been detected in the
charger. This fault will nearly always be set within the
first 30 seconds of operation. Once it has been
determined that the batteries and connections are not
faulty and fault 6 is again displayed after interrupting
AC power for at least 10 seconds, the charger must be
brought to a qualified service depot.
