Initialization Initialization. All LEDs of each channel turn on with
orange color one by one (after switching on the power).
Then top LED turn on with green color, if the slot is
empty. It means that the charger is ready.
When the battery is installed in the slot then the charging
will start immediately.
When all slots are empty.
Click to change
We DO NOT RECOMMEND to leave batteries inside the charger for a long storage period, as batteries can leak for various reasons and damage the
inner parts of the charger. If you have noticed any signs of batteries' defects then withdraw them from the charger and utilize.
ьYour charger can inconsiderably differ from the pictures in the manual.
ьThe producer reserves the right to change the package at his own discretion without modifying this manual.

Auto-start Auto-start. There is an auto-detection of IMR/Li-Ion 4.2V
or Ni-MH/Ni-Cd batteries, which will be shown by red
LEDs in proper line. Top LED will blink by green to show
charge current as 0.5A.
The charging will start automatically after 5 seconds.
When left slot has Ni-MH
battery and right slot has
Li-Ion 4.2V battery.
Charging Charging. Top LED shows by green color that the charging
goes with 0.5A current by default.
Always you can see an actual charge level (without button
touching). The blinking shows which charge stage is
going (>0%, >25%, >50% or >75%).
If the charge is finished then all LEDs will stay green and
stop blinking.
>0% >25% >50% >75% Finished
Advanced Operation
Selection of charge current Selection of charge current. You can change the current
during 5 seconds of Auto-start phase. Also while charging
click the button of proper slot to see the type of battery.
Anyway the blinking of top LED invites you to change the
current.
Shortly click the button to change the current cyclically:
0.5A -> 1A -> 0.1A -> 0.5A etc. Leave the button for 3
seconds to finish the selection.
0.5A 1A 0.1A
Hold to change Selection of battery type Selection of battery type. You can change the type of
battery during 5 seconds of Auto-start phase. Also while
charging click the button of proper slot. When you see the
blinking of top LED, hold the button (it works for any
charge current).
While pressing the button 4 LEDs will become red and
start blinking cyclically, one by one. Leave the button for
3 seconds to finish the selection. When the voltage is
higher than 1.7V then “Ni-MH” type will be passed during
cycling.

Auto-memorizing of battery type. The last used type of battery is memorized for quick start at next switching on. Also it is convenient
when the electricity is switched off temporary. Then the charger can continue the process with correct battery type.
How to prepare IMR/Li-Ion batteries for storage. When you need to keep your batteries for some months without usage then select the
type of battery “LiFePO4 3.7V” during charging. The voltage 3.7V is accepted for storage of these batteries.
Night mode of LED indication. The brightness of LEDs will become lower after 30 seconds from last button touching. Click the button to
return back maximal LED brightness.
Overtime prevention. The charger protects the batteries by limitation of charge time (20 hours for 0.5/1A and 30 hours for 0.1A current).
The time of charging. Precise charge algorithm utilizes independent negative delta V control (dV/dt) for Ni-MH/ Ni-Cd batteries
charging termination and optimized firmware for IMR and Li-Ion/Li-FePO4 batteries with Trickle charge and CC/CV stages. The charger
automatically stops when complete depending on the type of battery and can vary on different conditions.
Active temperature control. The charger design is developed for excellent heat dissipation. Anyway when the temperature will stay
much higher then the charge current will be reduced from 1A to 0.5A.
Battery stand-by charging. When the battery was left in the charger for a long time and the voltage was reduced below accepted level
then the charging will start again. It can help to keep the battery charged.
We recommend to use 1A current for batteries with capacity higher than 2000mAh. But 0.1A current is better for old batteries,
also when capacity is less than 300mAh. Otherwise, 0.5A can be used as default current.
Warning indication
Warning Constant 4 red lights after battery installation. The battery
has very high resistance and recognized as bad (it can be
primary battery or have low-quality chemistry).
Constant 4 red lights after 15 minutes of charge.
Li-Ion/LiFePO4 battery did not reach 3V during normal
time for restoration because of weak chemistry. You could
try again the charging, but we suggest to change this
