INTRODUCTION: Congratulations on purchasing this intelligent charging unit, which enables definitely quick and optimum charging to “AA” and “AAA” rechargeable batteries. With charging functions as well as individual LCD displays for the charging compartments, this charging unit is reliable, user-friendly and ideal for use in the home, office or on journey. The Charging unit CAUTIONS: 1. 2. The charger is restricted to charging NiCd and NiMH rechargeable batteries only.
. 4. 5. 6. Always follow the charging instructions for the rechargeable battery. Never use other kinds of the power cable and transformer apart from those originally supplied with the charging unit. The rechargeable battery may become hot during charging. User should take extra care when taking out the battery after charging. Unplug the charging unit from the power source when it is not in use. FEATURES: The Charging unit Charging the rechargeable battery in around 450mA charging current.
Test function to check the capacities of rechargeable batteries. The LCD of charger displays the different operating status of different modes. Trickle charging is available after the rechargeable battery is fully charged. To prevent overcharge, charger timer is available to limit the charging time to 10 hours for each charging process.

START CHARGING THE RECHARGEABLE BATTERIES After the transformer has been plugged into the power source (Figure 1), user should insert a rechargeable battery into the charging unit and plug the DC jack into the battery charger. Shortly afterwards, the battery voltage (for example, “1.38V”) and the “CHARGE” sign will be shown on the LCD.
OPERATING MODES OF THE CHARGING UNIT This powerful charging unit provides three operating modes: a. Charge up the rechargeable battery (CHARGE) – to charge up the rechargeable battery, automatically switch to trickle charge after rechargeable battery is full. b. Discharge then charge up the rechargeable battery (DISCHARGE) – to discharge the rechargeable battery then charge it for minimizing the memory effect. c. Check the rechargeable battery capacity in Ah (TEST).
has to take off and reinstall all batteries for selecting the new mode. Only one mode can be used for all compartments at the same time! CHARGING MODE The unit can charge up the rechargeable battery. It will automatically switch to trickle charging after the rechargeable battery is fully charged. During the process of charging, the display of voltage (Figure 2) and percentage (Figure 3) will alternate with the “CHARGE” sign on the LCD.
Percentage Indication of battery charging (Figure 3) Once the battery is full, the voltage will display permanently with the “FULL” sign. (Figure 4) The trickle charging will start shortly and around 5% of the charging current to keep the rechargeable batteries being full. The only default charging current is around 450mA during the charging process. (Figure 4) “FULL” sign shows -The battery is fully charged Note: The charging current of the rechargeable batteries depends on battery condition.
For proper reset, unplug the DC jack and wait for 5 seconds before plugging it into the charger. The estimated charging time of different battery size is tabulated in Table 1. Table 1. Charging Time with Two Types of Battery Size Size of Battery Charging current (mA) Estimated battery Capacity charging time AA ~7 hrs 2600mAh around 450mA AAA ~2.
defect batteries are placed to the charging unit, the “DEFECT“ sign (Figure 6) will show on the LCD of charger. The “DEFECT” sign will flash for a while on the LCD when the charger detects the battery condition. When the defective condition of the battery is confirmed, the “DEFECT” sign will turn on permanently.
make sure that the charged batteries are either NiCd or NiMH type and should not use the alkaline or carbon batteries. Carbon or Alkaline batteries may be the cause of the defect. Those types of batteries are NOT suitable for this charger. Another defect cause may come from the rechargeable batteries which voltage is too low. DISCHARGE MODE It is for removing the memory effect of rechargeable batteries. To select the discharge mode, please refer to the SETTING UP THE CHARGER above.
sign. The trickle charging will start shortly and around 5% of the charging current to keep the rechargeable batteries being full. TEST MODE To select the test mode, please refer to the SETTING UP THE CHARGER above. In the Test mode, the rechargeable batteries will first be fully charged and then discharged to determine the capacities and then fully charge the batteries again. During the first time of charging, the display of current (Figure 8) and voltage (Figure 9) will alternate on the LCD.
When in the discharging stage, the voltage (Figure 10) and discharging capacity (Figure 11) are displayed alternatively. The voltage (Figure 10) Test mode The discharging capacity (Figure 11) Test mode In the second time of charging, the voltage and the capacity are displayed alternately. When the rechargeable batteries are fully charged, the capacity (Ah) (Figure 12) and the voltage (V) (Figure 13) will be shown alternately with the “FULLTEST” sign on the LCD.
The capacity (Figure 12) Test mode The voltage (Figure 13) Test mode 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 rechargeable batteries are fully charged and kept at the charging unit. The “FULL” or “FULLTEST” sign will be displayed on the LCD according to the mode user selected.
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.
