the remaining charging time, the battery percentage,
charging voltage, charging current, temperature and
so on. The charger is fullycompatible with Li-ion,
IMR, INR, ICR, Ni-MH, Ni-Cd, LiFePO4 batteries. The
charger has a backlit LCD display, which can
display charging/charge-discharge-charge parameters
and charging status of thebattery.
The charger will select different charging methods
automatically accordingto different battery types.
For Li-ion, IMR, INR, ICR, LiFePO4 batteries, the
charger will apply normal Li-ion battery charging
mode (trickle, constant current, constantvoltage), for
Ni-MH/ Ni-Cd battery, the charger will apply -△Vfull
charging capacity termination method. Each channel
is fullyindependent, and has thefunction of calculating
the battery capacitythrough discharge.

Function Description
Charge curve (only 4.20V Li-ion batteries)
Charging to measure battery capacity
Automatically set the charging current
Put the Li-ion battery(under 3.4V)into the
charger, after fully charged, the charger will
automatically store the battery curve.
Put the Li-ion battery(above 3.4V)into the
charger, after fully charged, the charger will
not store the battery curve.
Note: The charger can only store two charging
curves at the same time. When there is a third
charge curve to be stored, the charger will
automatically cover the first charge curve.
Note: When the total capacity of the LCD
display and the actual capacity of the battery is
different, please discharge the battery and
recharge it again, the charger will store the
current battery charging curve, so that the total
capacity of the battery can be accurately measured
at the next charge, this function is only valid for
4.20V lithium battery.
“ ” flickering, the charged cumulative
capacity is displayed，
“ ” constant shinning，the battery total
capacity is displayed，（ The total capacity
of the battery is calculated based on the
accumulated capacity.
After a battery is inserted into any of the charging
slots, the charger will automatically set the most
suitable charge current according to the battery
characteristics. MAX 1.5A / MIN 0.1A.
Note: The default trickle current maximum is
800mA.
When the battery voltage is below 3.60V,
The charger automatically selects the
appropriate trickle current according to the
battery characteristics.
Li-ion(4.2V / 4.35V) battery
When the battery voltage is higher than 3.60V,
The charger automatically selects the
appropriate constant current according to
the battery characteristics.
When the battery voltage is below 3.30V,
The charger automatically selects the
appropriate trickle current according to the
battery characteristics.
LiFePO4 battery
When the battery voltage is higher than 3.30V,
The charger automatically selects the
appropriate constant current according to
the battery characteristics.

Battery activation function
If the charger will identify a protected lithium battery
that needs to be activated due to under-voltage,
it will attept to activate it in accordance with the
standard charging method.. If the charger will not
be able to activate the battery, it will be considered
to be damaged, corresponding channel prompt
“ ” and stop charging.
Lithium battery repair function
When the lithium battery was discharged to 0V,
the charger will apply the battery trickle charge
to repair the battery. The battery voltage will
slowly rise, and once it is fixed, the charger will
enter the normal charging mode. If the battery
voltage can not be raised for a long time, the
charger will identify it as damaged battery,
corresponding channel prompt “ ” and
stop charging.
1. The charger is only limited to charge the
lithium ion, IMR, INR, ICR, LifePo4 and Ni MH /
Ni Cd rechargeable battery: charging different
battery types may cause an explosion,
splitting, battery leakage, personal injury or
property damage.
Matters needing attention
When the battery is fully charged, it will
stop charging and prevent overcharge
High sensitivity -△V to determine the
battery charging saturation (Ni-MH /
Ni-Cd battery)
When the battery was fully charged, the LCD
screen will display “ ” Battery capacity
percentage “ ” Charging current “ ”
Charger automatically stops charging to prevent
the battery from overcharging and shortening
the battery Life.
For Ni-MH / Ni-Cd battery, the charger will use
-△V method to determine the saturation function.
It is an accurate method to determine end of
charge, that allows nickel-metal hydride /
nickel-cadmium batteries to achieve full saturation
without overcharging.

10. When the charger is not used, battery should
be removed, and the power cable should be
pulled out.
11. Do not insert conductive materials or metal
objects into the charger, in order to avoid the
short circuit or explosion.
12. Avoid mechanical vibration and shock to
prevent damage to the charger
13. Please carefully read the label on the charger;
ensure that the battery is placed correctly when
charging.
14. Please do not overcharge or over discharge
battery, please charge the battery as soon as
possible when it is used up.
15. Do not expose the charger to rain or snow.
16. Do not touch the heating surface, when the
charger full power, high power charge and
discharge, rechargeable batteries or charger
will give out heat.
2. Using environment: using temperature
-10~40℃, storage temperature: -20~60℃,
please do not store the charger directly in the
sunlight, near the heating equipment or other
high temperature sources.
3. The charger is suitable for adults over 18 years
old; children using the charger must be under
the supervision of adults.
4. It is prohibited to use this charger with batteries
that changed its shape, color or started leaking.
5. Do not use this charger to charge disposable
batteries, such as Zinc-Carbon (carbon zinc
battery), disposable lithium metal batteries,
CR123A batteries, CR2 batteries, and other
batteries which don’ t support charging,
otherwise it may cause the risk of fire or
explosion.
6. Do not charge the defective IMR battery, or it
may cause a short circuit and cause an
explosion.
7. When the charger starts working, it should not
be placed unattended. If charging process
suddenly stopped, you should not use the
charger, and read the instructions carefully.
8. Do not disassemble, assemble or repack the
charger, which may cause damage to the
charger or even explosion.
9. The charger should be used in a well ventilated
area. Do not use or put the charger in a damp
environment. Do not place inflammable and
explosive substances in the operating area.
