FUNCTION KEYS:
There are three easy-to-use function keys and four number keys in the charging unit:
Compartment
Number keys
DISPLAY
MODE key
CURRENT key
Compartment Number key
Press and release the Number key to select a particular battery compartment for charge
modes and/or display mode adjustment.
MODE key
The mode key shall first be pressed and held for about 1 second to activate the mode
change. The subsequent pressing of the mode key will enable to toggle between the
37
38
“Charge”, “Discharge”, “Test” and “Refresh” mode.To change the operating mode for
individual rechargeable battery, first press corresponding NUMBER key then press the
MODE key.
DISPLAY key
Press and release to select the displays of the charging current (in mA), time elapsed (in
hh:mm), the terminal voltage (in V) and accumulated capacities (in mAh orAh) during the
charging or discharging process.
To change the display content of a particular rechargeable battery, first press corresponding
NUMBER key then press the DISPLAY key.
CURRENT key
Press to select the amount of current to be applied (within the first 8 seconds after batteries
are inserted) in different operating modes (also see “Start charging the rechargeable
batteries” below).
OPERATING MODES OF THE CHARGING UNIT
This powerful charging unit provides the following operating modes:
a. Charge up the rechargeable battery (CHARGE) – to charge up the rechargeable
battery, automatically switch to trickle charge after rechargeable battery is full.
39
b. Discharge then charge up the rechargeable battery (DISCHARGE) – to discharge the
rechargeable battery then charge it for minimizing the memory effect.
c. Refresh the rechargeable battery (REFRESH) – to refresh the rechargeable battery to
its maximum capacity by charging and discharging the rechargeable battery
repeatedly until no further increase in the capacity is estimated. For old rechargeable
batteries or those have not been used for a long times, refreshing may bring the
rechargeable battery back to the optimum condition.
d. Check the rechargeable battery capacity in mAh/ Ah (TEST)
CHARGE MODE
Charging at 200 mA is the default-operating mode of the charging unit. User may select a
charging current of 200, 500 or 700 mA.
40
The estimated time of charging by various charging current is tabulated in Table 1.
Table 1. Charging Time with various charging current
Size of battery Battery Capacity Charging current selected (mA) Estimated charging time
700 ~3 hr 35 min
500 ~5 hr
AA 2500 mAh 200 ~13 hr
700 ~60 min
500 ~84 min
AAA 700 mAh 200 ~3 hr 30 min
Note:
zUser 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.
zIt may be necessary to charge and discharge the new rechargeable batteries for
several times in the beginning before the optimum capacity of the rechargeable
batteries can be obtained. And user is recommended to adopt once the "Refresh"
mode to the new rechargeable batteries in order to achieve the optimum battery
capacity.
zWhen 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

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. Then within 8 seconds from the last key pressing,
user may select the charging/ discharging current by pressing the CURRENT key.
Note:
The mode key shall first be pressed and held for about 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.
There is a 8-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.
