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-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.

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.

9

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.

10

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.

Discharging voltage

(Figure 7)

Discharge Mode

After fully discharging the battery(s), they will be re-chargedagain. 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

12

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

During the first charging cycle, the display of current (Figure 8) and voltage (Figure 9) will alternate on the LCD.

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.

CARE AND MAINTENANCE:

Extreme temperatures, vibration and shock should be avoided as these may cause the damage to the unit.

When cleaning the displays and casings, use a soft damp cloth only. Do not wet the exposed metal part of the charging unit. Do not use solvents or scouring agents as they may mark the LCD and casing.
