OPERATING INSTRUCTIONS. Battery Charger NT-2000
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, inner resistance and used charging
time.
The charging current can be selected from 200 mA, 500 mA, 700 mA and 1000 mA.
The charger can charge batteries of different type and size and with different
Page 4

capacity at the same time. It also integrates the minus delta voltage (-AV) 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 overheat detection to protect rechargeable
batteries and charger itself from overheating. The charger can only be powered by the
specially designed power supply. Operate and store it in dry indoor environment only.
This product fulfills European and national requirements related to electromagnetic
compatibility (EMC).CE conformity has been verified and the relevant statements are
available upon request. Unauthorized conversion and/or modification of device are
inadmissible because of safety and approval reasons (CE). Any usage other than
described above is not permitted and can damage the product and lead to associated
risks such as short-circuit, fire, electric shock, etc. Please read the operating instructions
thoroughly 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 damaged by improper use or failure to observe
these operating instructions .The warranty will then expire!
3.1Product Safety
The product must not be exposed to substantial mechanical strain or strong
vibrations.
The product must be protected against electromagnetic files, static electrical fields,
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.
Sufficient ventilation is essential when operating the charger .Never cover the
ventilating slots of the charger. Please take cautions especially when ambient
temperature is over 35 degrees Celsius, when the device is more easily entering
protection mode and thus longer charging time will be needed.
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 product. There is danger of
explosion!
Page 5
4
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 the battery lying around,
as there is risk, that children or pets swallow it. Batteries must not be dismantled,
short-circuited or thrown into fire. Never recharge non-rechargeable batteries. There is a
risk of explosion!
3.3 Miscellaneous
Repair works must only be carried out by a specialist/ specialist workshop.
If you have queries about handling the device, which are not answered in this
operating instruction, please check with the distributor for further help.
4. Operating Elements
MODE-Select mode: charging, discharging, refrsh, testing.
The button should be held down for more than one second to
activate mode.
SLOT-selection of the charge/discharge current value
button Works in the first eight seconds after inserting batteries,
or after activation of mode selection.
5. Power Supply
Only the shipped power adapter is
allowed to be used for this charger! When
the charger is powered up, all LCD
segments will light up momentarily. The “null” icon will be shown until
any batteries are inserted. When it’s powered up, the USB output can
be used a charger which can charge your phone or other electronics
no matter batteries are inserted or not.
6. Operation
Once a rechargeable battery is inserted, its
present voltage (for example,”1.2v”) will be displayed
for 4 seconds, then “200mA Charge” will be shown
on display for another 4 seconds as the default
charging current. If MODE or SLOT button is not
pressed during these 8 seconds, the Charging
process will start. After that charging current and/or
mode can be changed by activation <<MODE>> Discharged or
defective batteries may not be able to charge, and the display will
show “zero” icons. Sometimes, for fully discharged batteries “slow”
charger will be more effective Afterwards, the charging current can no
longer be changed without reinserting the rechargeable batteries or
re-power up the charger. If completely empty or defective batteries are
inserted into the charger, the “null” icon will be displayed on the display
and the charger will refuse to charge them. Sometimes those
Page 6

completely empty batteries ate still usable because they are not used for a long time and
the internal leakage current emptied the battery by itself. To avoid this refusal by the
charger, we suggest charging then with a normal 3v battery pack for a few seconds
before insert into the charger.
6.1 Mode Selection
Press and hold the “MODE” for 1 second to change the operating mode for all
charging slots.
Press the ： “MODE” button subsequently to toggle among the “Charge”,
“Discharge”, “Test” and “Refresh” mode.
After selecting the mode you can change the charging/discharging current
pressing<SLOT>.
6.2 Current selection
Within the first 8 seconds after insert the battery, press the “SLOT” button to select
desired charge current of 200, 500, 700 or 1000mA for slots inserted with batteries. After
expiration of 8 seconds the charger will go into setting mode. After that, the charging
current and / or mode can be changed by activation <MODE> and <SLOT>
7. Overheat protection
When overheating occurs, either batteries temperature over 55
degrees Celsius or charger controller board temperature over 70
degrees Celsius. The charging or discharging process will be paused
immediately and the charging or discharging current display will show
“000mA”. The charging/discharging process will only resume once the
temperature of the rechargeable batteries drops below 40 degrees
and charger controller board drops below 50degrees. This feature is
extremely important in protecting the batteries or charger itself from
over heating.
8. Operation Modes and Display
8.1 Operation Mode
Charge Mode: The rechargeable battery is charged up to its maximum capacity.
Stage1 Charge

Stage 2 Charge over, trickle charge.
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, the battery
will be charged at the pre-selected charging current. Discharging current is always half of
the selected charge current.

Refresh Mode: The rechargeable battery is charged and discharged repeatedly to
optimize to its maximum capacity. Old 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 tens hours or even days time before complete.
