INSTRUCTIONS FOR JAPCELL BATTERY CHARGER BC-4000
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 and used
charging time.
Insert the adaptor output terminal (DC plug) into the machine to
charge the battery.
The charging current can be selected from 200, 500, 700 and
1000mA. If two or less batteries are inserted in slot 1 and/or 4, the
charging current can go up to 1500mA or 1800mA.
The charger can charge batteries of different type and size and
with different capacity at the same time. It also integrates the mi-
nus delta voltage (-.V) function, which monitors the voltage over
the charging cycle. When battery is fully charged, the charger will
switch to trickle charging automatically. Therefore the battery will
be kept at its optimum capacity. The charger also includes over-
heat detection to protect rechargeable batteries and itself from
overheating.
The charger can only be powered by the specially designed pow-
er supply. Operate and store it in dry indoor environment only.
This product fullls European and national requirements related
to electromagnetic compatibility (EMC). CE conformity has been
veried and the relevant statements are available upon request.
Unauthorized conversion and/or modication of the device are
inadmissible because of safety and approval reasons (CE). Any
usage other than described above is not permitted and can dam-
age the product and lead to associated risks such as short-circuit,
re, electric shock, etc. Please read the operating instructions thor-
oughly before use and keep them for future reference.

3. Safety Instructions
We do not assume liability for resulting damages to property or
personal injury if the product has been abused in any way or dam-
aged by improper use or failure to observe these operating instruc-
tions. The warranty will then expire!
3.1. Product Safety
The product must not be exposed to substantial mechanical
strain or strong vibrations.
The product must be protected against electromagnetic les,
static electrical elds, extreme temperatures, direct sunlight and
moisture.
The manufacturer’s instruction for the respective batteries must
be observed, before they are charged.
The product should not be connected immediately after it has
been brought from an area of cold temperature to an area of
warm temperature. Condensed water might destroy the product.
Wait until the product adapts to the new ambient temperature
before use.
Sufcient ventilation is essential when operating the charger.
Never cover the ventilating slots of the charger, especially when
ambient temperature is over 35˚C.
3.2. Battery Safety
Correct polarity must be observed while inserting the batteries.
Non-rechargeable batteries, rechargeable alkaline batteries
(RAM), lead acid batteries and lithium batteries must not be
charged with this products. This could result in an explosion!
Batteries should be removed from the device if it is not used for a
long period of time to avoid damage through leaking. Leaking or
damaged batteries might cause acid burns when in contact with
skin, therefore use suitable protective gloves to handle corrupted
batteries.
Batteries must be kept out of reach of children. Do not leave bat-
teries lying around, as there is risk, that children or pets swallow
them. Batteries must not be dismantled, short-circuited or thrown
into re. Never recharge non-rechargeable batteries. This could
result in an explosion!
3.3. Miscellaneous
Repair works must only be carried out by a specialist or special-
ist workshop.
If you have queries about handling the device, which are not
answered in this operating instruction, please check with the dis-
tributor for further help.
4. Power Supply
Only the shipped power adapter is allowed to be used for this char-
ger!
When the charger is powered up, all LCD segments will light up
momentarily. The “null” icon will be shown until any batteries are
inserted.
5. Operation
Once a rechargeable battery is inserted, its present voltage (for
example “1.12V”) will be displayed for 4 seconds, then “200mA
Charge” will be shown on display for another 4 seconds.
If MODE or CURRENT button is not pressed during these 8 sec-
onds, the charging process will start. Afterwards, the charging cur-
rent can no longer be changed without re-inserting the recharge-
able batteries or re-power up the charger.
If defective batteries are inserted into the charger, the “null” icon
will be displayed on the display and the charger will refuse to
charge them.
If the battery voltage is too low the charger will refuse to
charge them!

5.1. MODE Selection
Press and hold the “MODE” button for 2 seconds to change the
operating mode for all charging slots.
Press the “MODE” button subsequently to toggle among the
“Charge”, ”Discharge”, ”Test” and “Refresh” mode.
5.2. CURRENT Selection
Within the rst 8 seconds after insert the battery, press the
“CURRENT” button to select desired charge current of 200, 500,
700 or 1000mA for slots inserted with batteries. The current can-
not be altered once the setting has been conrmed in the initial
stage. If one wants to change the applied current afterwards, the
rechargeable battery must be taken out and inserted again. The
maximum charging current is restricted by the current setting of
the rst inserted battery current. Discharge current is automati-
cally set to half of the selected charge current.
If two or less batteries are inserted in slot 1 and/or 4, the charg-
ing current can further be selected for 1500 or 1800mA. Maxi-
mum discharge current is limited to 500mA.
5.3. DISPLAY Selection
During or after the work mode complete, press the “DISPLAY” but-
ton to toggle among the display mode for voltage, current, capacity
and work time.
6. Overheat Protection
When overheating occurs, either batteries temperature over 55˚C
or charger controller board temperature over 70˚C, the charging or
discharging will be stopped immediately and the display will show
“000mA”. The charging process will only resume once the tempe-
rature of the rechargeable batteries drops to 40 degrees or charger
controller board drops to 50 degrees.
7. Operation Modes and Display
7.1. Operation Modes
Charge Mode: The rechargeable battery is charged up to its
maximum capacity.
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 nished, the battery will be charged at
the pre-selected charging current. Discharge current is always
half of the selected charge current.
Refresh Mode: The rechargeable battery is charged and dis-
charged 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, it can take 12
hours or even longer time before complete.
Test mode: Checks the present capacity of a rechargeable bat-
tery. 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.
7.2. Display
Charge/Discharge Current: The instantaneous current is dis-
played.
Time Elapsed: The charging/discharging time of the last cycle is
displayed.
Accumulated Capacity: The accumulated battery capacity is
displayed in mAh or Ah.
Charge Voltage: The instantaneous battery voltage is displayed.
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.
The Timer will resume and count from 0:00 again after the
time elapsed is longer than 20 hours. For example: 1:45 will
be shown if the time elapsed is 21hours and 45 minutes.
8. Maintenance
The device is maintenance-free but should be cleaned occasion-
ally. When cleaning, the device must be removed from any power
source. Only use dry and soft cloth to clear the housing of the
charger. Do not use abrasive or solvents.
9. Disposal
9.1. Disposal of waste electrical and electronic equipment
