INTRODUCTION:

Congratulations on purchasing the BC-500charging unit. This device provides quick and efficient charging of “AA” and “AAA” rechargeable NiMH or NiCd batteries. TheBC-500offers several charging functions as well as individual LCD displays for the charging compartments. TheBC-500charging unit is reliable,user-friendlyand ideal for use in the home, office or while travelling. We hope you enjoy your newBC-500charger.

The Charging unit

CAUTION:

The charger is restricted to charging NiCd and NiMH

rechargeable batteries only. The charger will not charge ZnMn, NiZn or Li-ionbatteries. 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.

Trickle charging is available after the rechargeable battery is fully charged.

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).

“FULL” sign shows -Thebattery is fully charged

(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.

Notes:

The default charging current is around 500mA.

The actual charging current of rechargeable batteries depends on their condition and is controlled by the charger. It Is not user selectable.

In the case that the power source terminates, the charger will reset. Once the power source is back to normal, the battery(s) will be treated as newly installed battery(s). For a proper reset, unplug the DC jack and wait 5 seconds before plugging it back into the charger.

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 5).

“--”is displayed when no battery(s) are in the charging unit.

(Figure 5)

IF ATTEMPTING TO RECHARGE ALKALINE OR CARBON BATTERIES, IT MAY CAUSE RUPTURE, EXPLOSION OR THE LEAKAGE OF HAZARDOUS LIQUIDS.

During the charging process, the “CHARGE” sign is displayed if any rechargeable batteries are placed into the unit. It is the responsibility of the user to make sure that the batteries are either NiCd or NiMH type andnot alkaline or carbon batteries.
