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 stratication. Both battery sulfation
and stratication will articially 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.

CHARGING VOLTAGES. TO MINIMIZE RISKS TO
ELECTRONICS, DISCONNECT THE BATTERY BEFORE
USING THIS MODE.
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,
666

CHARGE
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 ve (5) minute charge.
If unsuccessful when starting your vehicle, let the battery
rest for fteen (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
ashing) 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 being 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 to the Battery.
Do not connect the AC power plug 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

The 25% Charge LED will slowly
pulse “on” and “off”, when the
battery is less than 25% fully
charged. When the battery is 25%
charged, the red Charge LED will
be solid.
The 50% Charge LED will slowly
pulse “on” and “off”, when the
battery is less than 50% fully
charged. When the battery is 50%
charged, the red Charge LED will
be solid.
The 75% Charge LED will slowly
pulse “on” and “off”, when the
battery is less than 75% fully
charged. When the battery is 75%
charged, the orange Charge LED
will be solid.
The 100% Charge LED will slowly
pulse “on” and “off”, when the
battery is less than 100% fully
charged. When the battery is fully
charged, the green LED will be solid,
and the 25%, 50% and 75% Charge
LEDs will turn “off”.
During maintenance charging, the
100% Charge LED will pulse “on”
and “off” slowly. When the battery
is topped off and fully charged
again, the 100% Charge LED will
turn solid green. The charger can
be left connected to the battery
indenitely.

Charging Steps.
Voltage (V)
Step
Current (A)
Step 1 & 2: Analyze & Diagnose
Checks the battery’s initial condition, including voltage,
state-of-charge and health, to determine if the battery is
stable before charging.
Step 3: Recovery
Initializes the Recovery desulfation process (if needed)
for deeply discharged or sulfated batteries by pulsing
small amounts of current.
Step 4: Initialize
Starts the charging process with a gentle (soft) charge.
Step 5: Bulk
Begins the Bulk charging process based on the
condition of the battery and returns 80% of the battery’s
capacity.
Step 6: Absorption
Brings the charge level to 90% by delivering small
amounts of current to provide a safe, efcient charge.
This limits battery gassing and is essential to prolonging
battery life.
Step 7: Optimization
Finalizes the charging process and brings the battery
to maximum capacity. In this step, the charger utilizes
multi-layered charging proles to fully recapture capacity
and optimize the specic gravity of the battery for
increased run time and performance. The charger will
switch to Maintenance if the battery tells the charger that
more current is needed.

Step 8: Maintenance
Continuously monitors the battery to determine when
a maintenance charge should be initiated. If the battery
voltage falls below its target threshold, the charger will
restart the Maintenance cycle until voltage reaches its
optimal state and then discontinues the charge cycle.
The cycle between Optimization and Maintenance is
repeated indenitely to keep the battery at full charge.
The battery charger can be safely left connected
indenitely without the risk of overcharging.
Charging Times.
The estimated time to charge a battery is shown below.
The size of the battery (Ah) and its depth of discharge
(DOD) greatly affect its charging time. The charge time
is based on an average depth of discharge to a fully
charged battery and is for reference purposes only.
Actual data may differ due to battery conditions. The
time to charge a normally discharged battery is based
on a 50% DOD.
