Using 12V LITHIUM
This mode is designed for 12V lithium-ion (LiFePO4) baeries only. Some lithium-ion baeries may be unstable and unsuitable for charging. Consult the lithium
baery manufacturer before charging and ask for recommended charging voltage and current.
Using REPAIR (12V only)
This mode is for LEAD-ACID baeries only. It is an advanced baery recovery mode for repairing old, idle, straed or sulfated baeries. NOT all baeries can
be recovered. For opmal results, take the baery through a full charge cycle, bringing the baery to full charge, before using this mode. One REPAIR cycle can
take up to eight (8) hours to complete the recovery process and will enter to standby when completed. This mode uses a high charging voltage and may cause
some water loss in WET cell baeries. Plus, some baeries and electronics may be sensive to high charging voltages. To minimize risks, disconnect the baery
from the vehicle before using this mode.
Using 13,6 V SUPPLY
This mode converts the charger to a constant voltage, constant current DC power supply. It can be used to power 12 V DC devices. Prior to use, read your 12 V
DC 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 sengs
during baery repair or replacement. 13,6 V Supply Mode provides 13,6 V at 5A (Max). Both spark proof and reverse polarity protecon are disabled in this
mode. Do NOT allow the posive and negave baery clamp to touch or connect to each other as the charger could generate sparks.
Using 12 ALTERNATOR CHECK (press ALT-CHECK in standby)
Alternator % (12 V only) – Before the charger is connected with the baery which is well seled in the vehicle and ALTN CHECK buon is pressed, start the ve-
hicle and turn on the vehicle’s headlights. The digital display shows an esmated output percentage of the vehicle’s charging system connected to the charger’s
baery clamps, compared to a properly funconing system. The alternator percent range is from 0% to 100%, and LCD will show “OUTPUT GOOD”. Readings
below 0% (13.2 volts) will be regarded as LOW (LCD show “OUTPUT LOW”) and readings above 100% (14.6 volts) will be regarded as HIGH (LCD show “OUTPUT
LOW”). If you get a LOW or HIGH reading, have the electrical system checked by a qualied technician.
Using 12 BATTERY HEALTH CHECK
This mode is the advanced mode that takes a close look at the health of LEAD-ACID baery. Following parameters are what the charger checks to determine
baery health.
CCA (Cold Cranking Amperage): The starng current that the baery can provide to the engine at low temperature. More than 30% of the labeled value is
normal, and less than 30% of the labeled value requires replacement of baeries.
SOC (State of Charge): The rao of the remaining capacity of the baery aer a period of me or long-term shelf to the capacity of its fully charged state, com-
monly expressed as a percentage. When SOC = 0, the baery discharges completely, and when SOC = 100%, the baery is fully charged.
SOH (State of Health): The rao of performance parameters aer a period of service to nominal parameters of baeries. SOH of new baery is 100% and reject
baery is 0%.
Internal Resistance: The larger the internal resistance, the worse the capacity of the baery to absorb electricity.
How to operate: Press CCA buon will enter CCA RATE SET, you can press “+” and “-”buon to set CCA rate and default value is 500. When CCA rate has been
set, press CCA buon again, and LCD will display the actual CCA, SOH, SOC, and internal resistance. If SOC is less than 15% which means the baery power
is very low, the CCA detecon value may be incorrect, LCD will display “RETRY AFTER CHARGE”, please try to charge the baery and try the BATTERY HEALTH
CHECK mode again.
