1. Intended Use
The product is intended to charge and discharge NiCd or NiMH
rechargeable batteries. It provides four independent charging slots for
AA/AAA rechargeable batteries. The charger can also optimize and test
the maximum capacity of the rechargeable batteries. Each charging slot
has its own display to show various information, such as, charging current,
battery voltage, charged capacity, battery internal resistance and ellapsed
charging time.
The charging current can be selected from 200mA to 1400mA with 200mA
per increment. If 4 batteries are needed to be charged, then the maximum
current for each slot is limited to 1000mA. If battery in slot 2 or 3 is not
present, then the maximum current for slot 1 and 4 can be selected up to
1400mA.
The charger can charge batteries of different type and size and with
different capacity at the same time. It also integrates the minus delta
voltage (-ΔV) function, which monitors the voltage over the charging cycle.

5. Power Supply
The shipped power adapter is the power supply for this charger. In case
you need to use other power adapter, please be aware that power supply
has the correct polarity plug. Also please be noted that power supply need
be able to supply minimum 1.0A current. Low output power adapter could
lead to working improperly.
When the charger is powered up, 2.1 version number is displayed for 2s .
Then all LCD segments will light up momentarily. “null” will be shown until
any batteries are inserted.
6. Operation
Once a rechargeable battery is inserted, its present voltage( for example,
“1.12v”) will be displayed for 3 seconds, then 400mA default charging
current will be shown on display for another 3 seconds. If MODE or
CURRENT button is not pressed during this 6 seconds, the charging
process will start. During the first 6 second time, If any button is pressed,
the unit will wait for another 10s before finishing current slot setting. Press
“SLOT” button will confirm the setting right way without the needs of
waiting the 10s auto time-out time elapsed. All other battery can be
handled the same. So each battery can have its own setting independently.
While the previous battery slot setting mode is in effective (telling by the
flashing display of that battery slot LCD ), and the next battery is inserted,
then both battery slot display will be flashing, which means that any setting
change will be applied for all batteries in setting mode at the same time.
Once start normal working mode, charging current can no longer be
changed unless its working mode is changed or batteries are taken out
from charger and insert into charger again.
During normal working mode, if no particular slot is selected by pressing
the SLOT button, MODE, CURRENT and DISPLAY button are always
referring to 4 slots simultaneously. If a different working or display mode is
desired for particular slot, press the SLOT button to select the slot and then
press “Mode” or “Display” to select your wanted working or display mode..
6.1 Mode Selection
Press and hold the “MODE” button for 2 seconds to start working
mode selection for all four battery slot.
Press the “MODE” button subsequently to toggle among the
“Charge”, ”Discharge”, ”Test” , “Quick Test” and “Refresh” mode
When particular slot working mode need to be changed, press SLOT
button to select the desired slot and then press MODE button to
choose wanted working mode.
When working mode is changed, working current adjustment is
possible.
6.2 Current Selection
Within the first 6 seconds after inserting the battery or right after power up,
press the “CURRENT” button to select desired charge current for slots
loaded with battery at the same time. Current setting can not be altered
once the setting has been confirmed in the initial stage. If different working
current is needed afterwards, either changing the working mode or
rechargeable battery must be taken out and inserted again. Discharge
current is automatically set to half of the selected charge current.
Batteries for slot 1 and 4( no batteries present at slot 2 or 3), its charging
current can be selected for 1200 or 1400mA further. Slot 2&3 maximum
charging current is limited to 1000mA only.
6.3 Display Selection
“DISPLAY” button is for toggling display information for voltage, current,
capacity, work time etc.

6.4 SLOT Selection.
This button is used to select desired slots for different working mode,
charge current or display mode. Press SLOT button will start the slots
selection processing in the sequence cycle of 1->2->3->4->4 slots->exit.
7. Overheat Protection
With our improved charging circuit design, for normal good quality battery
with low impedance, heating built up on battery during charging process is
almost unnoticeable. However during the last charging stage, when battery
is almost full, batteries can become hot. This is normal: the larger charging
current applied, the more heat will build up. When battery temperature is
sensed to be over 60C, then over heat protection will be kicked in for
safety reason. Beside the four battery temperature sensor, there are also
two temperature sensor located on controller board, located at the area
where most heat is generated. So both battery and controller temperature
is monitored during the operation of the charger.
When overheating occurs, either from battery over 60 degrees Celsius or
controller board over 77 degrees Celsius, current working mode will be
automatically halted. If controller board over heat is detected, over heat
protection will be applied for the corresponding 2 battery slots at the same
time. If battery temperature over heat detected, only the over heated
channel will be halted accordingly. To tell if it is in the state of overheating
protection mode, charging current will be reduced to 0mA.
Charging/discharging process will only resume after battery temperature
drops below 40 degrees Celsius and/or charger controller board drops
below 50 degrees Celsius.
8. Operation Modes and Display
8.1 Operation Modes:
Charge Mode: The rechargeable battery is charged up to its
maximum capacity. Accumulated charging capacity is displayed
at mAH display mode.
Discharge Mode: It is used to reduce the memory effect. The
rechargeable battery is discharged to a preset battery voltage
(0.9v). Once discharge is finished, total accumulated discharging
capacity is displayed at mAH display mode, showing how much
energy is discharged from the battery, which is always referring to
the accumulated discharging capacity. No trickle charge current
will be applied after discharge cycle is finished.
Refresh Mode: The rechargeable battery is charged and
discharged repeatedly to optimize to its maximum capacity. Old
rechargeable batteries or rechargeable batteries that have not
been used for a long period of time can be restored to their rated
capacity. Depends on the selected charge current and battery
impedance, it can take tens hours or even days time before
complete. Refresh mode will make 3 complete discharge-charge
working cycles before complete. After charge cycle is complete,
the total charged capacity will be displayed in mAH display mode
even it is at discharging stage of that cycle.
Test mode: Checks the present capacity of a rechargeable
battery. The maximum capacity is determined by discharging the
rechargeable battery after it was fully charged. If the maximum
capacity is much lower than the rated capacity then it may reach
the end of its lifetime.
Quick Test mode: The charger will analyze the dynamic internal
battery resistance by applying a load current and this current
reading is referred to the voltage drop detected on the battery.
Within 10s, the tested battery resistance will be displayed in the
unit of milliohm. For good quality batteries, the internal resistance
is very low: in the range of 20 ~ 80 milliohms. If battery internal
resistance is over 500milliohms, then these batteries are not
good for supplying power to high current loads, such as digital
camera etc. But they can still be used for low energy loads, such
as clock, remote controllers etc. Always use batteries with close
internal resistance range when they are used in serial to achieve
maximum battery life. Alkaline and any other 1.5v batteries can
be tested on this charger as well. If a completely empty battery is
to be tested, it is not possible to give any correct reading. Please
be noted that since the internal battery resistance can be very
small, and contact resistance can be a major influence factor,
thus same battery tested in different slot or even at the same slot
with different contact condition, the reading can be varied for 10%
to 20%. This is normal.
When a high impedance battery( eg. Over 2500milli ohm) is
loaded onto the charger, due to its high internal impedance, real
displayed charging current can be much less than your
pre-selected charging current. When this happened, it doesn’t
means the charger is defective. Eventually it needs longer
charging time until fully charged.
8.2 Display
Charge/Discharge Current: instantaneous current is displayed.
Time Elapsed: The charging/discharging time of the last cycle is
displayed.
Page 4
Accumulated Capacity: The accumulated battery capacity is
displayed in mAh. For discharge mode, it is referring to the
accumulated energy discharged from that battery. For refresh mode,
previous charging capacity is displayed even when current working
stage is at discharge cycle.
Battery Voltage: The instantaneous battery voltage is displayed.
At QUICK TEST mode, it shows the internal battery resistance in
mili- ohm(0.001R).
Full: After the rechargeable battery is fully charged in any of the
operation modes, trickle charging will be started automatically.
Trickle charging prevents the rechargeable batteries from being
overcharged and compensates for self-discharging of the batteries
9. Maintenance
