Select different discharging current by pressing the CURRENT key (see “Note” in
Discharge mode and Table 2), within 8 seconds after inserting the batteries. (Or the
display will blink once to indicate the end of setting and the current cannot be changed
afterward.).
z It may take up to several days to finish the refreshing process, depending on the selected
discharging current.
z The maximum refresh current is 700 mA and is not affected by the number of
rechargeable batteries inserted.
TEST MODE
In the Test mode the rechargeable batteries will first be fully charged and then discharged to
determine the capacities. Finally, the rechargeable batteries are charged up again and the
capacity in (mAh) or (Ah) will alternate every 3 seconds with the FULL sign.
Press the MODE key within 8 seconds after inserting the rechargeable batteries; the Test mode
can be selected. (Hold the MODE key for about 1 second to activate the mode change. Press
and release the MODE key to select the “Charge”, “Discharge”, “Test” and “Refresh” mode)

NOTE:
z After selecting the Test mode the user may select different charging currents in the Test
mode by pressing the CURRENT key, within 8 seconds after the batteries are inserted.
The discharging current will be half of the selected charging current (see Table 3).

z The maximum charging current is 700 mA and is not affected by the number of
rechargeable batteries inserted.
z After the test mode is finished, the display will shift between the “Full” sign and the
battery capacity (in mAh or Ah) automatically in 3-second intervals until the rechargeable
batteries are removed. The user can switch to other displays by pressing the DISPLAY
key.
TRICKLE CHARGING
After the rechargeable battery is fully charged in any of the operating modes, the charger will
give a small amount of current to the rechargeable batteries to maintain the fully charged level.
This mode is automatically launched after rechargeable batteries are fully charged and kept in
the charging unit. The signal “Full” will be displayed on the LCD.

DISPLAY MODE INFORMATION
The user can use different display modes to monitor the rechargeable battery condition during
the different operations (see below figure and Table 4 to 7).

Capacity:
Milliamp hours: mAh is the capacity of the battery or the amount of charge added to a battery. If
a 2600mAh capacity battery is already half full when you charge it you will not add 2600mAh of
capacity to the battery.
Amp hours: Ah is the capacity of the battery or the amount of charge added to a battery. When
the battery charger shows values above 1999mAh, it changes to Amp hours. Due to the limited
space on the four displays the charger cannot display over 1999mAh. When the mAh
23
(Milliampere hour) reaches 2000 the display switches to Ah (Ampere hour) by moving the
decimal point. A mAh is 1/1000 of an Ah. Example: 2.29Ah and 2.34 Ah would be 2290mAh and
2340 mAh.
