Note:
User shall always observe the recommended maximum charging current of the
rechargeable batteries. In general, 200 mA is a recommended charging current if rapid
charging is not necessary. It is definitely safe and optimum to the rechargeable batteries.
When the transformer has been plugged to the power source, the version number of the
charger (for example “29” ) will be displayed first. Then all the segments will light up
momentarily and the “null” sign will be shown before batteries are placed. If damaged
batteries are placed to the charging unit, the charger will also show “null” on LCD.
“null” displayed - No battery or damaged battery is
placed to the charging unit
43
START CHARGING THE RECHARGEABLE BATTERIES
Once a rechargeable battery is inserted after the transformer has been plugged to the power
source, the battery voltage (for example, “1.39V”) will be displayed for 4 seconds. Then “200 mA
Charge” (default mode) will be shown on LCD for another 4 seconds, indicating that charging
with 200 mA is to be started if no alternation in setting is made.
Within this 8-second time from inserting the batteries the user may first select the
operating mode by the MODE key. (The mode key shall first be pressed and held for 1 second
to activate the mode change. The subsequent pressing of the mode key will enable to toggle
between the “Charge”, “Discharge”, “Test” and “Refresh” mode.)
Then within 4 seconds from the last key pressing, user may select the charging/
discharging current by pressing the CURRENT key.
Note:
There is a 4-second time allowed for choosing further functions after each key pressing. If no
more key is pressed, the LCD will blink one time to indicate the end of setting. Afterward, the
current can no longer be changed during the process and the selected mode will be undergone.
44
Charging current: 200 mA
After 4 seconds from no more keys
pressing, the LCD will blink once to
indicate the setting is confirmed and
the selected mode activated
Charge Mode
During charging, the different displays- Charging current (in mA), Time elapsed (in hh:mm),
Terminal voltage (in V) and Accumulated capacities (in mAh or Ah) may be toggled and
selected by pressing the DISPLAY key (refer Table 4).
After the rechargeable battery is fully charged, “Full” sign will be shown on the display and the
user may take out them at this time. Or if the rechargeable batteries are kept placing at the
compartments, trickle charging will start. The trickle charging current is around 5% of the
selected charging current to keep the rechargeable batteries being full.
45
“Full” sign is shown -The
battery is fully charged
Note :
The current cannot be altered once the setting has been confirmed in the initial stage.
This can avoid the user changing the current setting accidentally while doing setting on
other rechargeable batteries. If one wants to change the applied current afterward, the
rechargeable batteries must be taken out and inserted again.
The maximum charging current of other rechargeable batteries are restricted by the
current setting of the first inserted rechargeable battery. For instance, if the first inserted
rechargeable battery is set to charge at 700 mA, then the second, third and fourth
rechargeable batteries can be only set to charging at a maximum current of 700 mA.
46
Therefore, user is recommended to place the battery with the highest expected charging
current at Compartment 1 first. To release the restriction of setting charging current, user
shall take out all four rechargeable batteries from the charging unit.
To change the operating mode during charging, one can press the MODE key (for
selecting all rechargeable batteries) or NUMBER key then MODE key (for selecting
individual rechargeable battery). 4 seconds after the last key press the LCD will blink one
time to indicate the end of changing.
When overheating condition occurs (over about 53°C, usually due to too high a charging
current selected), the charging will be stopped immediately and the display will shown
“000 mA”, the charging process will only resume once the temperature of the
rechargeable batteries drops to a safe level. If overheat conditions continue to occur, the
rechargeable batteries shall be taken out to cool down and then charged at a lower
current.
When the battery is overheated the
charging will ceases automatically.
“000 mA” will be displayed.
47
For new rechargeable battery it is recommended to charge it with 200 mA current for reconditioning it from the long storage status.
DISCHARGE MODE
Discharge mode will first discharge the rechargeable battery then charge it. It is for removing the
memory effects of rechargeable batteries.
By pressing the MODE key within 8 seconds after inserting the rechargeable batteries, the
Discharge mode can be selected. (The mode key shall first be pressed and held for 1 second to
activate the mode change. The subsequent pressing of the mode key will enable to toggle
between the “Charge”, “Discharge”, “Test” and “Refresh” mode.)
Then user may also select different discharging current (see Table 2) by pressing the
CURRENT key, within 8 seconds after inserting the batteries. (The display will blink once to
indicate the setting has been confirmed and the current cannot be changed afterward.)
Discharging current: 250 mA
Discharge Mode
48
Note: The discharging current is always set to be half of the coming charging current whose
upper limit is 1000 mA (see Table 2). Therefore user is recommended to carefully select the
discharging current so that the charging current afterward will not be too high.

This process will recover the optimum capacity of the rechargeable batteries. By pressing the
MODE key within 8 seconds after inserting the rechargeable batteries, the Refresh mode can be
selected.
49
Refresh mode will start with discharging the rechargeable battery, then charging it. The
repeated discharging and charging cycles will be launched until no further increase in the
measured capacities is estimated.

By pressing the MODE key within 8 seconds after inserting the rechargeable batteries,
the Refresh mode can be selected. (The mode key shall first be pressed and held for 1
second to activate the mode change. The subsequent pressing of the mode key will
enable to toggle between the “Charge”, “Discharge”, “Test” and “Refresh” mode.)
Then user may also select different discharging current by pressing the CURRENT key
(see “Note” in Discharge mode and Table 2), within 8 seconds after inserting the
50
batteries. (Or the display will blink once to indicate the end of setting and the current
cannot be changed afterward.)
It may take up to several days to finish the refreshing process, depending on the selected
discharging current.
The maximum refresh current is 1000 mA and not affected by the number of
rechargeable batteries inserted.
