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.
It may be necessary to charge and discharge the new rechargeable batteries several
times in the beginning before the optimum capacity of the rechargeable batteries can
be obtained. It is recommended to use the "Refresh" mode for new rechargeable
batteries in order to achieve the optimum battery capacity.
When the transformer has been plugged into the power source, the version number of
the charger (for example “33” ) 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 into the charging unit, the charger will also show “null” on LCD.

selected mode will begin.
START CHARGING THE RECHARGEABLE BATTERIES
Once a rechargeable battery is inserted after the transformer has been plugged into 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 alteration 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. “Charge”, “Discharge”, “Refresh” and “Test” mode
may be chosen.
Charging current: 200 mA
After 8 seconds from the last key
press, the LCD will blink once to
indicate the setting is confirmed and
the selected mode is activated

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 toggle between the “Charge”,
“Discharge”, “Test” and “Refresh” mode.
There is an 8-second time allowed for choosing further functions after each key
pressing. If no more keys are pressed, the LCD will blink one time to indicate the end of

Note :
The current cannot be altered once the setting has been confirmed in the initial stage.
This prevents the user from changing the current setting accidentally while setting 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 the other rechargeable batteries is 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
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” will be shown on the display and the user
may take out them at this time. If the rechargeable batteries are left in place in the
compartments, trickle charging will start. The trickle charging current is around 5% of the
selected charging current to keep the rechargeable batteries full.

a charging current selected), the charging will be stopped immediately and the display
will read “000 mA”, the charging process will only resume once the temperature of the
rechargeable batteries drops to a safe level. If overheating conditions continue to
occur, the rechargeable batteries must be taken out to cool down and then charged at
a lower current.
For a new rechargeable battery it is recommended to charge it with 200 mA current to
re-condition it from the long storage status.

some charge over time.
Why does my display flash a number?
Your station will flash when first plugged in. If it continues to flash your a/c cord may be
defective.
It is not recommended to “condition” batteries until after they have been charged and used 10
times.
What type of batteries can I charge?
NiMH (Nickel Metal Hydride) or NiCd (Nickel Cadium) rechargeable batteries only may be
used in this product. Charging other types of batteries may result in failure of the charger.
As you use your batteries they will gain greater capacity and last longer. It is common for
your batteries to run down quickly at first.
My battery reads “Null”.
This charger requires at least .9v in the battery in order to charge it. If the battery is depleted
below that point, you will not be able to charge it on this battery charger.
