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 the user is
recommended to carefully select the discharging current so that the charging current afterward will not be too high.
•
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 toggle
between the “Charge”, “Discharge”, “Test” and “Refresh” mode.

Finally, batteries will be fully charged in discharge mode and “Full” will be displayed. If the user presses the DISPLAY key at this time, "charge" icon
instead of "discharge" icon will be displayed.
REFRESH MODE
Old rechargeable batteries and those that have not been used for a long time require refreshing. 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.
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.
Note:
z
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 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.
z
The maximum refresh current is 1000 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) 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 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:
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 afterward-discharging current will be half of the selected charging current (see Table 3).

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.
