Using 12V Repair. [Press & Hold]
12V Repair is an advanced battery recovery mode for repairing and storing, old, idle, damaged, stratified or sulfated batteries. Not all
batteries can be recovered.
Batteries tend to become damaged if kept at a low charge and/or never given the opportunity to receive
a full charge. The most common battery problems are battery sulfation and stratification. Both battery sulfation and stratification will
artificially raise the open circuit voltage of the battery, causing the battery to appear fully charged, while providing low capacity. Use
12V Repair in attempt to reverse these problems. For optimal results, take the 12-volt battery through a full charge cycle, bringing the
battery to full charge, before using this mode. 12V Repair can take up to four (4) hours to complete the recovery process and will
return to Standby when completed.
CAUTION:
USE THIS MODE WITH CARE. THIS MODE IS FOR 12-VOLT LEAD-ACID BATTERIES ONLY. THIS MODE USES A
HIGH CHARGING VOLTAGE AND MAY CAUSE SOME WATER LOSS IN WET (FLOODED) CELL BATTERIES. BE ADVISED,
SOME BATTERIES AND ELECTRONICS MAY BE SENSITIVE TO HIGH CHARGING VOLTAGES. TO MINIMIZE RISKS TO
ELECTRONICS, DISCONNECT THE BATTERY BEFORE USING THIS MODE.
Using JumpCharge
JumpCharge is an innovative new feature for jumpstarting low-voltage or dead vehicle batteries. The JumpCharge process is much
different than your traditional battery charger with an “engine start” feature. JumpCharge uses precision charge control to avoid
overloading the battery that shortens the life of your battery. To operate JumpCharge, the charger must be connected to a 12-volt
battery with the Battery Clamp Connectors connected. Press the JumpCharge button to begin jumpstarting your vehicle. Once
initiated, the Charge LEDs will begin showing the progress of the JumpCharge from 25% to 100%.When using this mode, the Charge
LEDs do not display the battery’s state-of-charge (SOC), only the JumpCharge progress. Once the 100% green LED is illuminated
solid, and the 25%, 50% and 75% Charge LEDs are “off”, the JumpCharge process is completed and your are ready to start your
vehicle. For optimal results, allow JumpCharge to complete its five (5) minute charge.
If unsuccessful when starting your vehicle, let the battery rest for fifteen (15) minutes and try JumpCharge again. Most vehicles will
start with one (1) JumpCharge, but larger vehicles with dual battery systems, may require an additional JumpCharge. If when
pressing the JumpCharge button, an Error Condition (Error LED and Standby LED flashing) illuminates, the battery is below 2-volts.
To JumpCharge a battery below 2-volts, press and hold the JumpCharge button for three (3) seconds, and JumpCharge will begin
jumpstarting your battery.
CAUTION. USE THIS MODE WITH CARE. THIS MODE IS FOR 12-VOLT LEAD-ACID BATTERIES ONLY. DO NOT USE
JUMPCHARGE MORE THAN TWO (2) TIMES WITHIN A TWENTY-HOUR (24) HOUR PERIOD. IF TWO (2) JUMPCHARGES
CANNOT SUCCESSFULLY START YOUR VEHICLE, HAVE YOUR BATTERY EVALUATED BY A LOCAL BATTERY STORE.
Connecting the Battery
Do not connect t
he supply power
until all other connections are made. Identify the correct polarity of the battery
terminals on the battery. The positive battery terminal is typically marked by these letters or symbol (POS,P,+). The
negative battery terminal is typically marked by these letters or symbol (NEG,N,-). Do not make any connections to the
carburetor, fuel lines, or thin, sheet metal parts. The below instructions are for a negative ground system (most
common). If your vehicle is a positive ground system (very uncommon), follow the below instructions in reverse order.
1.
Connect the positive (red) battery clamp or eyelet terminal connector to the positive (POS,P,+) battery terminal.
2.
Connect the negative (black) battery clamp or eyelet terminal connector to the negative (NEG,N,-) battery terminal
or vehicle or equipment chassis.
3.
Connect the battery charger’s power plug into a suitable electrical outlet, or restore power for hardwired units. Do
not face the battery when making this connection.
4.
When disconnecting the battery charger, disconnect in the reverse sequence, removing the negative first (or
positive first for positive ground systems).
Begin Charging
1.
Verify the voltage and chemistry of the battery.
2.
Confirm that you have connected the battery clamps or eyelet terminal connectors properly and the
supply power is
connected
.
3.
The charger will begin in Standby mode, indicated by an orange LED. In Standby, the charger is not providing any
power.
4.
Press the mode button to toggle to the appropriate charge mode (press and hold for three seconds to enter an
advanced charge mode) for the voltage and chemistry of your battery.
5.
The mode LED will illuminate the selected charge mode and the Charge LEDs will illuminate (depending on the
health of the battery) indicating the charging process has started.
6. The charger can now be left connected to the battery at all times to provide maintenance charging.
