5. Automatic charging indicator: it indicates the
charging rate you choose is automatic.
6. 4A current indicator: It indicates the charging rate
you choose is 4A.
7. 10A current indicator: It indicates the charging rate
you choose is 10A.
8. 20A current indicator: It indicates the charging rate
you choose is 20A.
9. 40A current indicator: It indicates the charging rate
you choose is 40A.
10. Charging state selecting switch: You can choose
the charge rates-4A, 10A, 20A or 40A ,by pressing
this switch. The default charging rate is the 4A.
11. Display Button Switch: You can choose what to
display on the panel by pressing the button. The
default display is the current charging rate.
12. Reverse Polarity LED Indicator: It is a red LED.
With AC input, when clips connected the battery in the

The charger will estimate automatically whether the
battery recondition is needed. It will recondition
the battery only when the voltage is lower than 13V
and when the battery has gone into float charge. The
maximum output voltage is 16.5±0.3V during the
process of recondition. The process cycles every
4±0.5h until the voltage is higher than 13V. If it cycles
5 times and the voltage is still lower than 13V,
there will be a code "F01" present on the display
panel, indicating error. Please replace the battery.
14. Charging State LED Indicator: It is a green
LED, when battery is charged at a constant current or
a constant voltage, the green LED flash. When
the battery goes into float charge, the charger will
cut receiving power to battery for1 minute to check
the charging state. The green LED illuminates. After
the check, if the battery is full charged or goes into
float charge, this green LED will also illuminate.
OPERATIONS
Warning! Working in the vicinity of a battery is
dangerous. Batteries generate explosive gases
during normal battery operation. For this reason, it
is of utmost importance that each time before using
a battery charger, you read this guide and follow the
instructions exactly.

Personal Precautions

f Someone should be within range of your voice or
close enough to come to your aid when you work near

f If battery acid contacts skin or clothing, wash
immediately with soap and fresh water. If acid enters
eyes, immediately flood eye with running cold water
for several minutes and get medical attention
immediately.
f Never smoke or allow a spark or flame in the vicinity
of battery or engine.
f Be extra cautious to reduce risk of dropping a metal
tool onto a battery. It might spark or short-circuit the
battery. These may cause an explosion.
f Remove personal metal items like rings, bracelets,
