5. Charger overview. Main controls.

MODE – selects charger operation mode: charge,

discharge, refresh, test (capacity), quick test (internal
resistance). To change the working mode for all 4 slots, this
button needs to be pressed for more than two seconds to
activate. When SLOT button is pressed prior to MODE, the
change will occur only within the selected charging slot.
DISPLAY – switches between various information:
charging/discharging currents, elapsed time, cell’s voltage,
capacity.
CURRENT – selects charging/discharging current for
inserted batteries. Button works for the first six seconds
after inserting batteries. Can be also used after pressing
MODE button.
SLOT – selects the desired slot(s) for different working
mode, charging current, or for different parameter display.

6. Power supply.

This charger should be used with original power
adapters only. When the charger is powered up, LCD
display turns ON, if there are no batteries inserted the
“null” icon should appear.

7. Basic operation.

Once rechargeable batteries are inserted, their voltage
level will be shown on the LCD display (for example 1.12V).
Voltage readings will be shown for the first 3 seconds, and
afterwards for the next 3 seconds display will show
“400mA” as default charging current. If not interrupted by
“Mode” and/or “Current” buttons within 6 seconds, the
default charge mode will start automatically. Operation
mode can be changed for all inserted batteries
simultaneously, anytime by holding “Mode” button, and if
change of electric current value is desired this operation
should be followed by pressing “Current” button. These
changes can be also made individually for each charging
slot by selecting “Slot” before holding “Mode” button.

The charger has the unique capability to detect and charge
near zero voltage cells. It will allow to charge every cell
with the open circuit voltage of min. 0.01V.

Mode selection.

Pressing and holding “Mode” button for about 2 seconds
activates mode change for all charging slots. Then short

8

pressing of “Mode” button will cycle between available
operating modes: “Charge”, “Discharge”, “Refresh”, “Test”,
“Quick test”.

For 3 seconds after selecting the desired operation mode
the user can adjust charging/discharging current by
pressing the “Current” button.

Additional mode/current changes can be applied to
individual cells by selecting each charging slot (pressing
“Slot” button repeatedly) before using “Mode/Current”
buttons.

Charging current selection.

For the first 6 seconds after the batteries are inserted the
user can adjust charging current by pressing the “Current”
button. Possible values are: 200, 400, 600, 800, 1000 mA.
Additional 1200, 1400 mA charging currents are available
when charging 1-2 pcs in the outer slots. Changes are
applied for all inserted batteries. Charging will start
automatically after 6 seconds from the moment last
button was pressed. If further changes are needed, the
user can select desired charging slot (“Slot” button) and
change mode/current anytime by using “Mode” followed
by “Current” button.
Please note that the recommended charging current
should be set to about 1/4 value in relation to inserted
battery’s rated capacity. For example for the 2000mAh
R6/AA batteries the recommended charging current is

9

500mA. For the 800mAh R03/AAA batteries the
recommended charging current is 200mA.

Full charge termination method -∆V is less accurate with
lower than recommended charging currents.

8. Overheat protection.

One of the most advanced and unique features of
everActive NC-3000 is the overheat protection system. The
charger was built using the latest, most advanced,
optimized, thermal efficient design. Overheat problem is
not likely to occur. But still, in general the temperature will
increase significantly when using highest charging currents
or bad quality cells. Therefore our charger is equipped with
six independent temperature sensors to protect both the
inserted batteries and the charger. If temperature of any
of the inserted cells rises over 60 degrees Celsius or the
charger’s internal circuitry temperature rises over 77
degrees then the operation will be interrupted and “0mA”
icon will be shown on display. The process will resume
when the battery’s temperature drops to 40 degrees
Celsius or the charger’s internal circuitry temperature
drops below 50 degrees.

9. Operation modes and display readings.

Charge mode – inserted batteries will be charged

automatically with the (pre)selected charging current.

10

Stage 1. Charging.

Various information can be read by pressing “Display” button – time of
operation, charging current, voltage level, charged capacity in mAh/Ah.

Stage 2. End of charging process, trickle charge is applied
to maintain full charge of the inserted batteries.

Icon “Full” will be shown on display. Pressing “Display” button will show
various information – time, trickle charging current, voltage level, charged
capacity in mAh/Ah - please note it is not the same value as battery’s
rated capacity.

Discharge mode – can be used to reduce and minimize
memory effect and lazy battery effect. Such cell will be
discharged to level of 0.9V. Please note that the cell stays
discharged after completing this process. Further action
will be needed to charge the cell.

Can be also used to discharge (test) primary (i.e. alkaline)
batteries. Please note that you should not try to recharge
primary, non-rechargeable batteries.

Stage 1. Discharging.

Pressing the “Display” button will show various information – time,
discharging current, voltage level, momentary capacity in mAh/Ah. When
complete, “0mA” current will be shown and the capacity measured during
the operation can be displayed. This advanced function can be used i.e. to
test the self discharge rate of the cells.

Refresh mode – a special combination of several charge
and discharge cycles. The charger tries to maximize the

11

capacity of older cells, which were not used for an
extended period of time. Can be used to initialize/form
new batteries and check their real capacity or to reduce
the memory effect. Please take note that this process can
take even few days to complete. At the end of the process
maximum cell capacity can be read from LCD display.

Please take a note – discharging current which is used to
determine the capacity is always ½ of the selected
charging current.

Stage 1. Several charge/discharge cycles with capacity test.

Pressing “Display” button will show various information – time,
discharging current, voltage level, momentary capacity in mAh/Ah.

Stage 2. End of refresh process. Trickle charge is applied to
maintain full charge of the inserted batteries.

Icon “Full” will be shown on display. Pressing “Display” button will show
various information – time, trickle charging current, voltage, maximum
measured capacity from the last cycle in mAh/Ah.

Test mode – can be used to test rated capacity of inserted
batteries. Please take note that new rechargeables may
need few charge/discharge cycles to reach their maximum
capacity. Batteries with much lower results than declared
should not be used. For the best results and performance
it is recommended to use the “everActive” rechargeables.

Please take a note – discharging current which is used to
determine the capacity is always ½ of the selected

12

charging current.

Stage 1. Charging.

Stage 2. Discharging.

Stage 3. End of discharge process. Charge is re-applied. At
this moment reading of measured capacity is available (by
pressing “Display” button).

Stage 4. End of test mode. Batteries are fully charged and
trickle charge is applied to maintain full charge of the
inserted batteries.

Pressing “Display” button will show various information – time, trickle
charging current, voltage level, measured capacity in mAh/Ah.

Quick test mode – determines the internal resistance of
the inserted cell (can be used also with the primary i.e.
alkaline batteries). The result is displayed in mΩ
(milliohms). For the proper results, the inserted cell
should not be empty (discharged). The test needs about
10s to complete. Please take a note that the result should
be considered as approximate – it may differ when
compared to a specialized laboratory tester. It is
recommended to repeat the test 2-3 times for each cell.
The test is performed correctly when the difference
between the following results is less than 30%.

The general rule for this test is: lower value is better.
How to read the results:

13

20-80 mΩ - best quality, mainly new cells able to deliver
high output currents – can be used in the high drain
devices i.e. flashlights, digital cameras, toys.
81-200 mΩ - standard quality, still can be used in most
devices.
201-500 mΩ - not able to deliver high currents,
recommended for low drain devices i.e. clocks, remotes,
computer mouse and keyboard. Often, for the Ni-MH
cells, the result can be improved by using the “Refresh”
mode.
>500 mΩ - low quality or old, used up cells. For the best
reliability and safety reasons we recommend to replace
such cells with the new ones. Charging time of such cells
can be significantly longer and they can heat up during
the charge/discharge process. In most devices they will
show “discharged battery” warning even when they are
fully charged and just removed from the charger.

Please note that this test is not accurate when using
additional C/D size charging adapters.

The contact points/pins have to be clean and in good
condition to achieve good, reproducible results.

Stage 1. Testing. After 10s after the cell is inserted/the
“Quick test” mode is applied the result can be read from
the LCD display.
