home, office or while travelling. We hope you enjoy your new BC-500
charger.
The Charging unit
CAUTION:
The charger is restricted to charging NiCd and NiMH
3
rechargeable batteries only. The charger will not charge ZnMn,
NiZn or Li-ion batteries. Never use this device to charge other
types of batteries, such as alkaline, lithium, carbon zinc battery
or any other type of battery that is not specified.
The charging unit shall only be used at normal indoor room
conditions.
Always follow the charging instructions for the rechargeable
battery.
Never use other kinds of power cables or AC wall adaptors
apart from those originally supplied with the charging unit.
The rechargeable battery(s) may become hot during charging.
Take extra care when removing the battery after charging.
Unplug the charging unit from the power source when it is not in
use.
FEATURES (Charging unit):
Roughly 500mA charging current.
Individual LCD display for different compartments.
Ability to charge both “AA” and “AAA” rechargeable batteries
4
simultaneously.
Minus delta voltage (-dV) detection for charge termination.
Defective battery detection.
Discharge mode (first discharging and then charging) to remove
memory effect of rechargeable batteries.
Test function to check the capacity of rechargeable batteries.
The charging/discharge/test function can be launched
independently and simultaneously for each rechargeable battery
in the compartments.
The LCD of the charger displays the operating status of the
different modes.

After the AC wall adaptor or DC car power
adaptor has been plugged into an
appropriate power source (Figure 1), insert
a rechargeable battery into the charging
unit and plug the DC jack into the battery
charger. After about 5 seconds the status
will be displayed, along with the battery
voltage (example, “1.38V”) Then the
“CHARGE” sign will be shown on the LCD.
(Figure 1) (AC power adaptor shown)
OPERATING MODES OF THE CHARGING UNIT
The charging unit provides three operating modes:
1. (CHARGE) – to charge up the rechargeable battery.
Automatically switches to trickle charge after rechargeable battery
is full.
2. (DISCHARGE) – to discharge the rechargeable battery then
charge it for minimizing the memory effect.
6
3. (TEST) Check the rechargeable battery capacity in Ah.
CHARGE MODE
When in this mode, the unit charges the rechargeable battery(s). It will
automatically switch to trickle charging after the rechargeable battery is
fully charged.
During the charging process, the display will show the “CHARGE” sign
on the LCD. It will also show alternate between the percentage (Figure
3) of the battery charged, and the voltage (Figure 2) of the battery.

Once the battery is full, the voltage will display the “FULL” sign (see
Figure 4).
The trickle charging then starts providing around 5% of the charging
current to keep the rechargeable batteries full.
The estimated charging time of the different battery sizes is tabulated in
Table 1.

When the AC wall adaptor is first plugged into the power source,
all the segments light up momentarily and then the version
number of the charger (for example “48”) is displayed.
If no batteries are in the unit, the “--” sign is displayed (see Figure

Carbon or Alkaline batteries may cause the charger to display the
“DEFECT”. These types of batteries are NOT suitable for this
charger.
DEFECT INDICATOR
The “DEFECT” indicator will flash (Figure 6) for a while on the LCD while
the charger detects the battery condition. If a defective battery condition
is detected, the “DEFECT” sign will remain on until the defective
battery(s) are removed.
Warning: This charger will not necessarily recognize all types of
defective batteries. Owner discretion is required before attempting to
charge batteries of any condition.
If “DEFECT” is displayed, a bad battery has been
placed into the charging unit.
(Figure 6)

DISCHARGE MODE
To select the Discharge Mode, press the MODE key for 3 seconds after
the status of the batteries is displayed. Discharge mode will first
discharge the battery, then charge it. When discharging, the
“DISCHARGE“ sign and battery voltage (Figure 7) will be shown on the
LCD.
After fully discharging the battery(s), they will be re-charged again. The
display of voltage and percentage will alternate on the LCD. Once the
battery is full, the voltage will be displayed with the “FULL” sign. The
charger will switch to trickle charge with around 5% of the charging
current to keep the rechargeable batteries full.
TEST MODE
Press the MODE key for 5 seconds after the status of the batteries is
displayed, and the Test mode can be selected. In Test mode the

rechargeable batteries will first be fully charged and then discharged to
determine the battery(s) capacity(s). They are then fully charged again.

TRICKLE CHARGING
After the rechargeable battery is fully charged, the charger will give a
small amount of current to the rechargeable batteries to maintain the
fully charged level. This stage is automatically launched after the
rechargeable batteries are fully charged and kept in the charging unit.
The “FULL” or “FULLTEST” sign will be displayed on the LCD according
to the mode user selected.
