Note:
 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
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.)
Then the 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
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 is not affected by the number of
rechargeable batteries inserted.
TEST MODE
21
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) of (Ah) will be estimated and shown after the discharging ends.
By pressing the MODE key within 8 seconds after inserting the rechargeable batteries, the
Test mode can be selected. (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.)
Note:
 After selecting the Test mode the user may select different charging currents in the

 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).
