12V Lithium charge mode is designed for 12-volt
lithium-ion batteries only, including lithium iron
phosphate.
CAUTION:
USE THIS MODE WITH CARE. THIS
MODE IS FOR 12-VOLT LITHIUM BATTERIES
ONLY. LITHIUM-ION BATTERIES ARE MADE AND
CONSTRUCTED IN DIFFERENT WAYS AND SOME
MAY OR MAY NOT CONTAIN A BATTERY
MANAGEMENT SYSTEM (BMS). CONSULT THE
LITHIUM BATTERY MANUFACTURER BEFORE
CHARGING AND ASK FOR RECOMMENDED
CHARGING RATES AND VOLTAGES. SOME
LITHIUM-ION BATTERIES MAY BE UNSTABLE AND
UNSUITABLE FOR CHARGING.
Using 12V AGM+. [Press & Hold]
12V AGM+ charge mode is designed for 12-volt
advanced AGM batteries only. Advanced AGM
batteries are a new battery technology typically found
in start-stop micro-hybrid vehicles. These batteries
accept a higher than normal charging voltage around
15.5-volts. 12V AGM+ charge mode is NOT suitable
for traditional AGM batteries. Consult the battery
manufacturer before using this mode.
CAUTION:
USE THIS MODE WITH CARE. THIS
MODE IS FOR 12-VOLT LEAD-ACID ADVANCED
AGM BATTERIES ONLY. THIS MODE USES A HIGH
CHARGING VOLTAGE AND MAY CAUSE SOME
WATER LOSS IN WET (FLOODED) CELL
BATTERIES OR OVERCHARGE IN SOME
BATTERIES.

CHARGE
Using 16V Lithium. [Press & Hold]
16V Lithium charge mode is for 16V lithium-ion batteries only, including lithium iron phosphate batteries. 16-volt lithium-ion batteries
are commonly found in racing vehicles, where the alternator might be removed, or used to improve the performance of the injector or
fuel pump.
CAUTION:
THIS MODE IS FOR 16-VOLT LITHIUM BATTERIES ONLY. LITHIUM-ION BATTERIES ARE MADE AND
CONSTRUCTED IN DIFFERENT WAYS AND SOME MAY OR MAY NOT CONTAIN A BATTERY MANAGEMENT SYSTEM (BMS).
CONSULT THE LITHIUM BATTERY MANUFACTURER BEFORE CHARGING AND ASK FOR RECOMMENDED CHARGING RATES
AND VOLTAGES. SOME LITHIUM-ION BATTERIES MAY BE UNSTABLE AND UNSUITABLE FOR CHARGING.
Using 16V AGM. [Press & Hold]
16V AGM charge mode is for 16V AGM batteries only. 16-volt AGM batteries are commonly found in racing vehicles, where the
alternator might be removed, or used to improve the performance of the injector or fuel pump.
CAUTION:
USE THIS MODE WITH CARE. THIS MODE IS FOR 16-VOLT AGM BATTERIES ONLY. DO NOT USE ON A 12-VOLT
BATTERY. CONSULT THE BATTERY MANUFACTURER BEFORE CHARGING AND ASK FOR RECOMMENDED CHARGING
RATES AND VOLTAGES.
Using 13.6V Supply. [Press & Hold]
13.6V Supply converts the charger to a constant current, constant voltage DC power supply. It can be used to power 12VDC devices,
including; tire inflators, oil changers, coffee pots, seat heaters and more. 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 provides 13.6-volts at 5A with overload protection at 6A
(Max).
CAUTION:
THIS MODE IS FOR 12-VOLT LEAD-ACID BATTERIES ONLY. PRIOR TO USE, READ YOUR 12VDC DEVICE MANUAL
TO DETERMINE IF IT IS SUITABLE FOR USE WITH THIS MODE. BOTH THE SPARK PROOF AND REVERSE POLARITY SAFETY
FEATURES ARE DISABLED IN THIS MODE. DO NOT ALLOW THE POSITIVE AND NEGATIVE BATTERY CLAMP OR EYELET
TERMINAL CONNECTORS TO TOUCH OR CONNECT TO EACH OTHER AS THE CHARGER COULD GENERATE SPARKS.
CHECK THE POLARITY OF THE BATTERY TERMINALS BEFORE USING THIS MODE.
