charging current can be set up to 1500 or 1800 mAh when two batteries are charged.
 Fast charging – 70 mins to charge up 2000 mAh batteries
 Individual LCD display for all compartments
 Charging both “AA” and “AAA” rechargeable batteries simultaneously
 Overheat detection to protect rechargeable batteries from over-charging
 Minus delta voltage (-dV) detection for charge termination
 Damaged batteries detection

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 toggle between the “Charge”, “Discharge”,
“Test” and “Refresh” mode. To change the operating mode for an individual rechargeable
battery, first press the 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 or Ah) during the
charging or discharging process.
To change the display content of a particular rechargeable battery, first press the
corresponding NUMBER key then press the DISPLAY key.
7
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 the rechargeable battery (CHARGE) – to charge the rechargeable battery,
automatically switches to trickle charge after the rechargeable battery is full.
b. Discharge then charge the rechargeable battery (DISCHARGE) – to discharge the
rechargeable battery then charge it to minimize 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 time, refreshing may bring the rechargeable
battery back to the optimum condition.
d. Check the rechargeable battery capacity in mAh/ Ah (TEST)
