minimize risks, disconnect the battery from the vehicle before using this mode.
13.6V SUPPLY – Once at + REPAIR tap CHARGE MODE to access
This mode converts the charger to a constant voltage, constant current DC power
supply. When the charger is not connected with battery, it can be used to power
12VDC devices. Prior to use, read your 12VDC device manual to determine if it is
suitable for use with this mode. As a power supply, it can also be used to retain a
vehicle’s on-board computer settings during battery repair or replacement. 13.6V
Supply Mode provides 13.6V at 9.5A with overload protection at 10A (Max). Both
spark proof and reverse polarity protection are disabled in this mode. Do NOT
allow the positive and negative battery clamp to touch or connect to each other as
the charger could generate sparks.
BOOST CHARGE – Press BOOST CHARGE button to access
USE THIS MODE WITH FULL ATTENTION AS THE CHARGING CURRENT
IS 20A. This mode is for 12-volt LEAD-ACID batteries only. To operate BOOST
CHARGE, the charger must be connected to a 12V battery with the battery clamps
connected. Press the BOOST Charge button to begin jumpstarting. For optimal
results, allow BOOST CHARGE to complete its 5-minute charge. After 5-minute
boost charge, the charger will automatically enter mandatory 5-minute rest for
cooling down, and it does NOT work when any button is pressed. After mandatory
cooling down, the charger will automatically enter Standby Mode, whether 100%
battery level indicator is illuminated or not, and you are ready to start your vehicle.
If unsuccessful when starting your vehicle, let the battery rest for 15 minutes
and try BOOST CHARGE again. Most vehicles will start with one (1) BOOST
CHARGE, but larger vehicles with dual battery systems, may require an additional
BOOST CHARGE. Do not use BOOST charge more than two (2) times within a
24-hour period. If two (2) BOOST charges cannot successfully start your vehicle,
have your battery replaced or evaluated by a battery service dealer.
CHARGING STEPS
During the charging process, the charger performs the following operations.
BATTERY LEVEL INDICATORS
LED
Explanation
25% 50% 75% 100%
The 25% Charge Red LED will slowly flash when the
battery level is less than 25%. At 25% the LED will be
solid.
25% 50% 75% 100%
The 50% Charge Red LED will slowly flash when the
battery level is less than 50%. At 50% the LED will be
solid.
25% 50% 75% 100%
The 75% Charge Red LED will slowly flash when the
battery level is less than 75%. At 75% the LED will be
solid.
25% 50% 75% 100%
The 100% Charge Green LED will slowly flash when
the battery level is less than 100%. At 100% the LED
will be solid. The 25%, 50% and 75% Charge LEDs
will turn off.
STEP 1
–
DIAGNOSIS
Checks if battery is connected with the charger; also
checks battery voltage.
STEP 2
–
DESULFATION
(if needed) If battery voltage is too low,
automatically generates pulsing current for up to 5 hours to remove sulfate.
STEP 3
–
ANALYZE
(if needed) Checks if the battery voltage reaches minimum
charging threshold after desulfation; charging begins if the battery voltage is
sufficient.
STEP 4
–
SOFT START
Charges with step-ups of constant current.
STEP 5
–
BULK CHARGE
Charges with constant maximum current until battery
voltage reaches charging threshold.
STEP 6
–
ABSORPTION
Continues to charge with gradually declining
current until battery is at 100% charge.
STEP 7
–
VALIDATION
Tests if the battery can hold charge.
STEP 8
–
MAINTENANCE
Continuously monitors the battery; charging
current will adapt to the variable battery voltage.
